Definitions

  • the invention relates to a moulding mixture for manufacture of mouldable products. More particularly, this invention relates to a moulding mixture for manufacturing products from plant fibers.
  • a product formed using the moulding mixture of the invention may be of any convenient shape and may optionally include partitions or protrusions.
  • Many currently used products are made from plastics and petroleum based derivatives or natural wood. Plastics materials do not degrade and cannot be disposed of effectively. Such materials may be collected and often recycled. However, recycling does not completely solve the environmental problems posed by many plastics because the breakdown of these compounds releases harmful gases into the atmosphere. Plastics products which are not recycled may lead to land and water pollution causing irreparable damage to the environment. Wood-based products, such as paper boxes and paper pulp packaging, lead to deforestation.
  • chipboard or particle board uses a compression method and adhesives. However it is not convenient to produce shaped articles from chipboard.
  • thermo-foaming process relies on foam formation of the material to shape the material into receptacles.
  • Khashoggi patents all teach the addition of at least 10 wt % of starch and quote a typical range as being 10-80 wt %.
  • Khashoggi US patent number 5,783,126 teaches a preferred starch content of 30 to 70% which gives rise to a problem due to the relatively high cost of starch-based binder and the excess time and energy necessary to remove the solvent.
  • Khashoggi therefore teaches the addition of inorganic fillers or aggregates.
  • the Khashoggi patents also teach the addition of inorganic fillers in relatively high concentrations and quote a typical level of inorganic aggregate as being greater than 20 wt %.
  • a moulding mixture for use in moulding a product including:
  • a moulding mixture for use in moulding a product including: (i) 40 to 60 wt% plant fibre pieces optionally combined with 0 to 2 wt% added starch; and (ii) 10 to 55 wt % water and 3 to 10 wt % one or more water-soluble binding agents or adhesives

  • a moulding mixture for use in moulding a product including:
  • the moulding mixture of the present invention is suitable for a range of moulding processes known to the person skilled in the art.
  • the moulding mixture has also been
  • novel process suitable for use with the moulding mixture of the present invention may be any novel process suitable for use with the moulding mixture of the present invention.
  • the aforementioned novel process comprises a further step of trimming the edges of the product prior to coating the product in step (h).
  • trimming is conducted using a die-cut machine.
  • Other methods for trimming may also be used within the scope of the invention including polishing and/or sanding down the edges of the product.
  • the main component of the mixture is plant fibers which are bonded together by an adhesive which hardens as it cures, the cured product will not disintegrate immediately upon contact with liquid.
  • the product will take a minimum often minutes before it starts disintegrating and could last as long as one hour.
  • the density of the product is dependent on the pressure applied during formation of the product. Therefore, the product is liquid- resistant enough to withstand treatment with water-resistance agents or decorative materials.
  • the cured product formed from the moulding mixture can be further treated with a water resistant material or decorative materials.
  • the plant fibers can come from any source.
  • suitable plant fibres maybe chosen from the group comprising rice stalks, wheat stalks, sugar cane, corn leaves, banana leaves, corn crops, roots, grass, flowers, recycled paper or combinations thereof.
  • the size of the fibers affects the texture of the final product. The requirements of the final product will dictate the size of the fibers required. For example, a table top will need to be strong and is flat so this will allow larger longer pieces of fiber to be used than those used in a smaller or curved item such as a cup.
  • the plant fiber pieces used in the composition and process are in the range from 0.1mm to 5 mm. More preferably, the length should between 1 mm to 2 mm. However it is possible to use plant fibers which have been ground smaller than 1 mm, eg. powdered.
  • the binding agents or adhesives which are used to bind the fibres are water soluble and preferably are environmental friendly. It is preferred that non-biodegradable plastics or synthetic polymers are not used so that the process provides a biodegradable product although it is to be appreciated that biodegradability of the binding agents or adhesives is not essential where the end product does not need to be biodegradable.
  • water based biodegradable adhesives are used so that the end product is biodegradable.
  • latex-based adhesives such as Neoprene, are used in accordance with the invention.
  • any added starch used in accordance with the present invention is selected from the group comprising tapioca flour, ground sweet potatoes or any other root powder, corn starch, flour and combinations thereof. While corn starch and flour are suitable for use as added starch in accordance with the present invention the results are not as good as when other starch sources are used. There is no need to modify the added starch prior to processing.
  • step (a)(i) The fiber and flour or other added starch are mixed together initially in step (a)(i) to produce an even mixture. Further, if the liquid ingredients contact the flour before it is evenly mixed in, the flour will form lumps and this will create holes in the product as the starch is removed during the process.
  • step (b) the mixture is stored in a sealed container until required for step (b) to prevent the mixture from drying out.
  • the mixture is preferably stored at room temperature prior to use to prevent hardening.
  • the mixture may be stored at a temperature in the range from the freezing point of the mixture to about 25 °C. Preferably, the mixture is stored at a temperature in the range from 15 to 25°C.
  • step (a) occurs at a temperature at or below 25°C.
  • the water used can be of any quality. The water quality chosen will depend on the intended use for the product. For example, non-potable water such as sea water may be used as well as normal utility water. However, products intended for food contact must be made from drinking quality water.
  • the water is converted to steam during the process. This aids in spreading the mixture evenly in the mould. The mixture does not foam because the pressure prevents the mixture from expanding, and the action of the steam is directed towards spreading the mixture throughout the mould. Once the spreading is complete, the steam is removed to allow the product to dry.
  • the amount of pressure applied to the mould will affect the density of the final product. The denser the product, the harder it is. Therefore, if a more flexible product is desired then a lower pressure should be used.
  • the pressure is applied to the mould, any excess material will be squeezed out of the mould.
  • the pressure is at about 4000 PSI.
  • the strength of the product produced using the moulding mixture will depend on four factors:
  • the type of adhesive including the crystallization rates and viscosity of the adhesive. Different types and grades of adhesive contribute differently to the strength of the products. Different crystallization rates and viscosities of different adhesives result in different products. Crystallization determines the rate of initial strength development. The faster the rate of crystallization, the faster the rate of strength development. Viscosity influences the inherent strength of the adhesive film, the solution viscosity, and solids content. The higher the polymer viscosity, or the higher the molecular weight, the higher the film strength, the higher the adhesive viscosity, or the lower the solids at a given adhesive viscosity.
  • the product design may enhance the strength of the overall product. For example, a box with ribs will be stronger than one without.
  • sugar cane fibre provides a moulded product that is inherently resilient but not brittle.
  • rice husks tend to provide a product that is hard, but comparatively brittle.
  • Products produced from the moulding mixture of the invention can be recycled with very minimal loss of original material and with no harmful by-products. In other words, a product can be recycled to produce an almost identical product.
  • products produced from the moulding mixture of the invention will breakdown and disintegrate to form substances which are not detrimental to the environment. This is because all of the materials used are non-toxic and are mostly natural and edible. If the products are collected after disposal and left to decompose, the resultant manure can be used as a fertilizer because of the fact that the main component of the product is plant fibers.
  • the plant fibers may be obtained from the unwanted parts of crops such as rice- stalks, sugar cane pulps or any other fibers that are not directly consumed. This helps to dispose of such waste from harvesting sites, factories etc. which would otherwise be disposed of by burning and thus causing air pollution. The use of such raw material helps to reduce this air pollution.
  • the present invention relates to biodegradable as well as non-biodegradable materials. Since the manufacture of products from biodegradable materials requires that steam be able to escape from the mould, the use of biodegradable materials to produce large objects, such as table tops, has not been viable due to the extended drying time required for such large objects.
  • the moulding mixture of the present invention may be used in a range of moulds known to the person skilled in the art.
  • the moulding mixture is also suitable for use in a novel mould, comprising one or more valves in the top and/or bottom ends of the top and/or bottom parts of the mould to enable steam to be removed wherein the openable valves are closed when the mixture is placed into the mould and then the valves open when the steam needs to be removed.
  • this novel mould consists of at least two parts - a top and a bottom part and is typically made of metal.
  • moulds which come in three or more parts provided that there is still a top and a bottom part.
  • the mould is preferably compressed vertically, that is, in a downward and upward manner so that the top part is compressed against the bottom part.
  • valves enable the steam to be removed from the mould so that the product will dry out faster. Further, the steam is removed more quickly and the product is less likely to be burnt.
  • the moulding mixture of the present invention enables the processing of a certain prescribed mixture to form products of various shapes and sizes suitable for protective packaging such as boxes and receptacles and coverings for electronic goods, cushioning packaging for delicate and fragile electronic and computer systems and components, food and beverage containers such as cups, plates, lunchboxes etc, building material and prefabricated boards such as partitions, ceiling boards and other shaped products eg garment hangers, horticultural and agricultural planters and pots, and disposable golf tees.

  • the moulding mixtures of examples 1 to 40 were used to make golf tees according to the moulding process of the present invention.
  • the golf tees were of good quality and suitable for their intended use.
  • Further moulding mixtures were prepared, analogous with the compositions of examples 1 to 40, except that the sugar cane pulp added as a source of fibre was replaced with fibre chosen from the group comprising wheat stalks, tea leaves, rice stalks, rice husks mixed with rice stalks, corn cobs including the leaves and the carbonaceous residue of burnt coconut shells.
  • the molding mixtures comprising each of the listed sources of fibre were used to make golf tees according to the moulding process of the present invention.
  • the golf tees comprising each different type of fibre were compared with the aforementioned golf tees comprising sugar cane pulp. While there were differences in quality of the golf tees depending on the type of fibre used, these differences did not have any significant effect on the performance of the golf tees.
  • Of the aforementioned sources of fibre only rice husks have any inherent starch content. The rest of the listed fibre sources have no inherent starch content and therefore make no contribution to the starch content of the moulding mixture. Accordingly, when rice husks were used to make the moulding mixtures of examples 1 to 40, the proportion of starch present was slightly greater than the quantities listed in the table.
  • the mould 20 shown in the drawings has a top mould part 21 and a bottom mould part 22.
  • the top mould part 21 has a valve 23 located in its upper surface 24.
  • the bottom mould part has a cavity 25 to receive mixture 26.
  • When mould 20 is closed there is a gap 27 of about 1 mm between the top mould part 21 and the bottom mould part 22. Once closed, pressure is applied to upper surface 24.
  • the valve 23 is operated either manually or automatically via a controller (not shown). Typically, the valve 23 is opened (see Figure 6) when the temperature of the mould 20 is at about 110°C. Once the article 28 has dried, the mould 20 is opened and the article 28 removed. Manufacturing an Article from the Mixture
  • the process commences at A with pre-heating the mould 20 to 70°C. This heating is only required the first time that the mould 20 is used because in a continuous process the mould 20 would be at about 140°C from forming the last article 28 and is actually cooled to 70°C at B. Once formed the article 28 is removed from the mould 20 at C to be trimmed, sealed and further treated as desired. Once the mould 20 is brought to about 70°C, the mould 20 is opened (see D of Figure 2) and overfilled with mixture 26 (see E). Ideally the mixture is kept at ambient temperature (about 25 °C) or at least within the range of 15 to 40 °C. The mould 20 is intentionally overfilled to ensure that there is sufficient mixture to evenly and completely fill the mould 20.
  • the mould 20 is not left cold because when the mixture 26 is compressed under pressure, the solids in the mixture would be forced and compressed to the bottom of the mould and water would separate from the mixture and be squeezed out through the gap or air vent. If the temperature goes above 100°C, the moisture will turn into steam too quickly and can cause an explosion. However when the mould 20 is hot (70°C to 100°C) and the materials are compressed, the moisture will immediately transform into vapor and start to look for a space or gap to escape. This action will move the solids in the mixture into all the open spaces in the mould 20 with excess mixture seeping out of the mould 20. This action typically takes 5 to 10 seconds.
  • the mould 20 is then closed (see F of Figure 2).
  • F of Figure 2 When closed, there is typically a gap 27 of about 1 mm between the top 21 and bottom 22 parts of the mould through which steam and excess mixture can escape.
  • a pressure of about 4000 PSI is applied to the top of the mould 20 (see G) for about 3 to 10 seconds until excess mixture starts coming out of the gap 27 between the mould parts 21 and 22.
  • the appearance of the excess material indicates that the mixture 26 has spread evenly throughout the mould 20 - this is especially important where the product is not flat and the mixture will need to move up the sides of the mould 20.
  • the pressure also ensures that the shape of the product is maintained (that is, there is no foaming), and controls the desired density/porosity of the product.
  • the pressure is reduced to atmospheric and then increased back to a pressure in the range of from 500 to 1500 PSI. In the examples we used a pressure of about 1000 PSI. Then the temperature was increased to about 140°C. The pressure is reduced to prevent an explosion due to the water toning into steam too quickly.
  • the steam will be rushing out through all openings and the faster the steam can escape, the faster the product will cure and this reflects the importance of having a valve 23 being operated to let the steam escape.
  • the valve 23 is opened to increase the rate of steam escaping (see H).
  • the mould 20 is opened and the substantially dried article 28 removed (see I).
  • the edge of the article has to be trimmed using a die cutting machine or manually (see J).
  • the article is then optionally coated with further adhesive by spraying or dipping (see K) and heated at 100°C to 140°C for about 10 seconds to 10 minutes to cure the adhesive. In the example we used temperature of about 130°C for about 8 minutes.
  • the article may be further coated with Neoprene to further enhance its water resistance (see L). Typically about 3 grams of Neoprene is used per square foot of the product. The coating is applied by spraying or dipping.. In addition, a decorative painting or print can be added to the surface of the product.
  • FIG 8 shows a top part of a mould (100) comprising mould part (101) and valve (102).
  • Valve (102) sits in a complementarily shaped cavity (103) in mould part (101) and is free to move relative to mould part (101).
