Description

Production method and equipment for recycling carbon black to produce black masterbatch or black glue

The present invention relates to a production method and production apparatus, particularly a production method and production apparatus for producing black masterbatch or black rubber from recycled carbon black obtained from scrap tires or rubber.

Please refer to Figure 9, which shows the structure of carbon black. The global automotive market is estimated to produce approximately 30 million scrap tires annually, with Taiwan producing approximately 120,000 of these tires. However, there is still a lack of effective recycling and reuse of these scrap tires into carbon black and waste recycling. This has resulted in the inability to achieve an environmentally friendly circular economy and reduce waste and garbage. New environmentally friendly carbon-reducing materials, such as black masterbatch made from recycled carbon black, cannot be created. Carbon black 6 is composed of over 95% carbon, along with small amounts of oxygen, sulfur, nitrogen, and ash. It is an extremely light and fine black powder. The particle size of carbon black primary particles 63 ranges from approximately 10 to 500 nm. These particles are densely linked into spherical aggregates 62, representing the primary structure of carbon black. These aggregates, adsorbed by van der Waals forces, form agglomerates 61. Finally, after pelletization, they become the carbon black particles commonly found in the market. Electron microscopy reveals significant differences in particle size and structural complexity. Because carbon black 6 does not exist as a single primary particle 63, its particle size is often expressed in terms of specific surface area (as shown in Figure 9). Generally, furnace-processed carbon black has few surface functional groups and is generally neutral to slightly alkaline. No one on the market has developed a method for adjusting the surface functional groups and, consequently, the pH value of carbon black to achieve optimal properties based on the needs of different applications through specialized surface modification methods. Carbon black is an important black coloring material. It is derived from hydrocarbons through thermal cracking or incomplete combustion. Different grades of carbon black are also available. Due to the large number of carbon black types, the American Society for Testing and Materials International (ASTM) has standardized carbon black nomenclature to help differentiate them. Carbon black for rubber is generally classified and named according to ASTM D1765. The naming method consists of four parts: the curing speed (N/S), which is composed of an English letter N or S representing the curing speed and three Arabic numerals representing the range of carbon-nitrogen surface area and the different levels of carbon black structure; the specific surface area of carbon black (1-9); and the structural complexity. Commonly used rubber grade carbon blacks include specifications such as N220, N330, N660, and N990. According to the different functions and uses of carbon black, it can be roughly classified into: carbon black for scrap tires and rubber applications, pigment carbon black, and conductive carbon black. Generally, black masterbatch uses 100% virgin pigment carbon black (Virgin Carbon Black). Carbon black has a small primary particle size and high oil absorption. Due to its high cost, no one in the market directly uses recycled carbon black, which has a large primary particle size, low oil absorption, low coloring power, and no commercial value. Its source and quality are unstable, and its surface properties differ from those of pigment carbon black. It is difficult to finely disperse it in plastic carriers and has low coloring power. Furthermore, no one uses equipment to produce black masterbatch or black glue with appropriate physical properties and processability. This greatly reduces its practicality, which is an area that technicians and consumers in this field are eager to break through.

To address the aforementioned shortcomings of existing technologies, the main purpose of this invention is to provide a production device for recycling carbon black to produce black masterbatch or black glue. The device comprises: a coarse screening and grading mechanism, a carbon black surface pretreatment and mixing mechanism, a dispersion mechanism, a molding mechanism, and an inspection mechanism, thereby overcoming the difficulties of existing technologies.

A secondary purpose of this invention is to provide a production method for recycling carbon black to produce black masterbatch or black rubber, comprising the following steps: (1) coarse screening and classification, (2) carbon black surface pretreatment and mixing, (3) dispersion, (4) molding, and (5) inspection.

Another object of the present invention is to provide a production method and production device for recycling carbon black to produce black masterbatch or black rubber, which uses waste tires or rubber to obtain recycled carbon black and a coarse screening and grading mechanism to screen and grade it to remove some impurities; a carbon black surface pre-treatment mixing mechanism to coat and modify the carbon black and combine it with a resin carrier and add a dispersant to obtain a carbon black powder mixture; a dispersing mechanism to break up the carbon black powder mixture into carbon black agglomerates and then refine it to achieve dispersion conditions; a molding mechanism to extrude and cut the pellets to produce black masterbatch with plastic as the resin carrier or black rubber with artificial rubber as the resin carrier (Black Rubber Masterbatch); an inspection mechanism to ensure that a certain proportion of the black masterbatch or black rubber (Black Rubber Masterbatch) color development is used to confirm that hue and dispersion meet the set conditions. Its application in foamed or rubber-soled footwear reduces material costs and the product's carbon footprint, replacing carbon black produced by petroleum processes and achieving environmental protection and carbon emission reduction.

Another object of the present invention is to provide a production method and apparatus for recycling carbon black to produce black masterbatch or black glue, effectively improving its ease of use, achieving environmental protection, carbon reduction, and waste reduction, and serving as a production material for use in a circular economy.

The problem that this invention aims to solve is that the global automotive market is estimated to produce about 30 million scrap tires each year, and Taiwan produces about 120,000 scrap tires. However, there is still a lack of effective recycling and reuse of these scrap tires and the recycling of waste into carbon black, which makes it impossible to achieve an environmentally friendly circular economy and reduce the generation of waste and garbage. The invention aims to create a new environmentally friendly carbon-reducing material that uses recycled carbon black to make black masterbatch. Generally, carbon black is an important black coloring raw material, and black masterbatch uses 100% virgin carbon black (Virgin Carbon Black). Carbon black has a smaller primary particle size and higher oil absorption. Due to its high cost, no one in the market uses recycled carbon black, which has a larger primary particle size, lower oil absorption, lower coloring power, and no commercial value. Its source and quality are unstable, and its surface properties differ from those of pigment carbon black. It is difficult to mix and disperse it in plastic carriers, and its coloring power is low. Furthermore, no one uses equipment to produce black masterbatch or black glue with appropriate physical properties and processability, which greatly reduces its practicality.

Through a grading control method and purification steps to remove impurities, the quality of the material is improved and the material is environmentally friendly and suitable for mass production. The recycled carbon black obtained through high-temperature pyrolysis of scrap tires or rubber is mixed with pigment carbon black in a certain proportion (as shown in the first figure).

The carbon black surface pre-treatment mixing mechanism 2 is connected to the coarse screening and grading mechanism 1 and coats and modifies the surface of the recycled carbon black. The recycled carbon black screened by the coarse screening and grading mechanism 1 is input and uniformly mixed with a certain proportion of a resin carrier, and a dispersant is added for pre-mixing to obtain a uniform carbon black powder mixture.

The granulated black masterbatch 101 of the present invention can be used in foamed shoe materials, while the black rubber masterbatch 102 can be used in rubber-soled shoe materials, thereby reducing material costs and the product's carbon footprint. Not only can it replace carbon black produced by petroleum processes, achieving environmental benefits and reducing carbon emissions, but the new black masterbatch 101 or black rubber masterbatch 102 made from recycled carbon black can also be used as a production material that is sustainable and recyclable (as shown in Figures 1, 2, 3, 4, and 5).

Please refer to Figure 6 for a production method for recycling carbon black to produce black masterbatch or black rubber. The recovered carbon black (rCB) and the steps of the production method for producing black masterbatch or black rubber from recycled carbon black include: coarse screening and grading S1, carbon black surface pretreatment and mixing S2, dispersion S3, molding S4, and inspection S5.

The aforementioned (1) coarse screening and grading S1 utilizes a coarse screening and grading mechanism 1 to screen and grade the recycled carbon black obtained through high-temperature pyrolysis of waste tires or rubber, removing some impurities. Through a grading control method and purification steps to remove impurities, the quality of the material is improved and an environmentally friendly material suitable for mass production is produced. In the coarse screening and grading mechanism 1 of step (1) of the production method for producing black masterbatch from recycled carbon black, the recycled carbon black obtained through high-temperature pyrolysis of waste tires or rubber is mixed with pigment carbon black in a certain proportion.

The aforementioned (2) carbon black surface pre-treatment mixing S2: a carbon black surface pre-treatment mixing mechanism 2 is connected to the coarse screening and grading mechanism 1 of the coarse screening and grading mechanism S1 of the production method for producing black masterbatch in step (1), and the surface of the recycled carbon black is coated and modified, the recycled carbon black sieved by the coarse screening and grading mechanism 1 of the coarse screening and grading mechanism S1 is input and uniformly mixed with a certain proportion of resin carrier, and a dispersant is added for pre-mixing. The carbon black powder is mixed to obtain a uniform carbon black powder mixture; the carbon black surface pre-treatment mixing mechanism 2 of the carbon black surface pre-treatment mixing S2 of the production method for producing black masterbatch of the recycled carbon black is input into the coarse screening and classification S1, the coarse screening and classification mechanism 1 is screened, and a certain proportion of the resin carrier is uniformly mixed. The resin carrier includes a plastic of ethylene-vinyl acetate copolymer (Ethylene-Vinyl Acetate Copolymer). Acetate (EVA) and the artificial rubber are styrene-butadiene rubber (SBR); the dispersant in the carbon black surface pre-treatment mixing mechanism 2 of the carbon black surface pre-treatment mixing step (2) of the carbon black surface pre-treatment mixing step S2 is, but is not limited to, polyethylene wax or an aliphatic compound.

The aforementioned (3) dispersion S3 utilizes a dispersion mechanism 3 connected to the carbon black surface pre-treatment mixing mechanism 2 of step (2) of the production method for recycled carbon black to produce black masterbatch. The carbon black powder mixture is subjected to high-temperature kneading dispersion and secondary roller method, or a double-shaft extruder for dispersion, to break up the carbon black powder mixture into carbon black agglomerates and further refine it to achieve dispersion conditions.

The aforementioned (iv) molding S4 utilizes a molding mechanism 4 connected to the dispersing mechanism 3 of the dispersing S3 of step (iii) of the production method for producing a black masterbatch from recycled carbon black. The carbon black powder mixture, which has been broken into carbon black agglomerates, is then extruded and pelletized to produce a black masterbatch 101 with the plastic as a resin carrier or a black rubber 102 with the synthetic rubber as a resin carrier . The black masterbatch 101 or the black rubber 102 is formed by uniformly mixing a certain proportion of carbon black with the plastic as the resin carrier or the synthetic rubber as the resin carrier. The black masterbatch 101 or the black rubber 102 can be used as a coloring material for shoe materials such as midsole plastic foam or rubber base materials.

The aforementioned (5) test S5 utilizes a testing mechanism 5 connected to the molding mechanism 4 of the molding S4 of step (4) of the production method for producing black masterbatch from recycled carbon black, and causes a certain proportion of the black masterbatch 101 or the black rubber masterbatch 102 to develop color to confirm that the hue and dispersion meet the set conditions. The testing mechanism 5 of step (5) of the production method for producing black masterbatch from recycled carbon black in test S5 causes the black masterbatch 101 or the black rubber masterbatch 102 produced from the recycled carbon black to develop color at a certain proportion (4%, 1%). The testing mechanism 5 of step (5) of the production method for producing black masterbatch from recycled carbon black in test S5 causes the black masterbatch 101 or the black rubber masterbatch 102 produced from the recycled carbon black to develop color at a certain proportion (4%, 1%). Masterbatch 102 can be formulated as needed to meet industrial application requirements. Colorant testing methods can be used to test dispersibility (as shown in Figure 4) to ensure its jetness is comparable to that of standard products. Recycled carbon black (rCB) is produced by high-temperature forging after decomposition of scrap tires or recycled rubber products. A comparison of conventional carbon black and recycled carbon black (see Table 1 below) includes characteristics such as particle size, jetness, specific surface area, oil absorption, impurities, and carbon footprint. Recycled carbon black (rCB) has the advantage of significantly lower carbon content, but drawbacks include impurities, poor dispersibility, and low jetness when coloring. Improvements are needed to overcome these drawbacks. The specific surface area and oil absorption of recycled carbon black lie between those of conventional carbon black N330 and N660, so appropriate carbon black specifications can be selected to adjust the hardness.

Note: *1 The carbon footprint calculation table provides relative reference values based on current manufacturer data and may vary depending on the manufacturing process. Figure 7 shows the distribution of carbon black nitrogen adsorption surface area and oil absorption value.

Figure 8 shows a comparison of three types of carbon black aggregates.

The particle size distribution of recovered carbon black agglomerates shows that the D50 particle size of recovered carbon black is higher than that of N330. Large particles may affect processability and dispersibility, while excessive impurities can affect physical properties. The present invention utilizes coarse to fine filtration to remove oversized carbon black particles and reduce impurities.

Therefore, a new black masterbatch can be obtained by mixing pigment carbon black, recycled carbon black and dispersant. By adjusting the ratio according to the present invention, the physical properties and processability can be improved. When the recycled carbon black accounts for about 1/3 to 1/2 of the total carbon black, appropriate physical properties can be obtained; if 5-10% of the total amount of dispersant is added, the wettability of the black agglomerate can be increased, and appropriate physical properties and processability can be obtained. Since the use of colorants is based on the added amount in the total formula, the comparison method of the black masterbatch 101 and the black rubber (Black Rubber Masterbatch) 102 is to use the black masterbatch 101 in a ratio of 4% and 1% of the total composition, and to develop color under a resin carrier as the color comparison condition of dark shade (Full shade) and light shade (Tint shade); the black masterbatch 101 or the black rubber (Black Rubber Masterbatch) of the present invention is used as the color comparison condition of dark shade (Full shade) and light shade (Tint shade). Masterbatch 102 is a product formed by uniformly mixing a certain proportion of carbon black with a resin carrier. It can be used as a colorant for shoe materials such as midsole plastic foam or rubber soles. To reduce waste and promote reuse, recycled carbon black from scrap tires can be used as a raw material in a black masterbatch. This recycled carbon black can then be used in shoe materials, creating a new, environmentally friendly, and waste-reducing material that promotes a circular economy.
