Description

Functional sterilization and deodorant coating using nano silver and charcoal

Conventional technology using charcoal is used for various deodorization, purification, and water purification purposes by using charcoal powder pulverized in solid phase or various sizes to produce deodorizing effect by using pores of charcoal itself. .

However, as charcoal in high humidity or submerged charcoal, as time passes, it can be seen that the environmental conditions in the pores of charcoal gradually grow mold due to the humidity and environment where bacteria can grow.

Charcoal itself does not generate mold, but many bacteria and molds feed on organic substances adsorbed in the pores, causing bacteria to multiply in the pores of the char. As a result of falling side effects, it is usually a hassle to go through the process of washing with water and drying in order to discard it or to separate bacteria.

In addition, existing waterborne paints contain large amounts of water, which means that they are always exposed to the risk of corruption. Existing water-based paints use various chemical preservatives and organic antimicrobial agents, the main component of which is formalin, in order to prevent its own decay.

In particular, various chemical preservatives should be suppressed as much as possible because they can threaten the human body and natural ecosystem due to toxin action and cause fatal adverse effects on our living environment.

Using charcoal, nano silver and anion minerals as the main raw materials, the efficiency of deodorization, air purification, sterilization and deodorization of various bacteria such as harmful gases and odors generated in various buildings and furniture in our daily life This excellent eco-friendly functional aqueous paint is produced, applied to indoor building, applied and dried, and the air purification effect, antibacterial effect, anion emission, far infrared emission, It removes harmful gases generated in various buildings by warming blood, cleans the air, and absorbs and sterilizes airborne bacteria in the air, so we use functional sterilization and deodorant paints to make our living space safer and more comfortable. Wish to provide

The present invention relates to the production of functional silver and charcoal paint which effectively sterilizes bacteria adsorbed in pores with air purification by using strong sterilizing power of charcoal powder and nano silver having a deodorizing power with a porous structure. same.

Activated charcoal or charcoal (325 mesh size) pulverized using charcoal powder produced at a high temperature of more than 1200 degrees Celsius is used.The charcoal itself, whose main component is carbon, does not cause mold, but due to the porous structure of charcoal, Gases and various organic compounds are naturally adsorbed.

The fungus feeding the adsorbed organic materials can occur in the pores of the char.Because a lot of bacteria and molds are fed to the organic substances adsorbed in the pores, bacteria grow in the pores of the char. Due to the intrinsic function of charcoal deodorization performance is markedly reduced results, it is necessary to antibacterial treatment charcoal in order to effectively remove these bacteria.

These harmful bacteria can be reduced to some extent by the ability of the charcoal itself, but no effect can be expected at all where many organic substances are adsorbed or in high humidity.

Therefore, there is a need to give artificially more powerful and effective sterilization and antibacterial ability.

In general, silver has excellent conductivity, blocks static electricity and electromagnetic waves, has a water vein blocking effect, and is known to be a semi-permanent inorganic substance exhibiting toxicity, antimicrobial, and sterilizing effects from ancient times.

In general, in order to have antibacterial activity against various bacteria through silver, it is necessary to secure a silver ion concentration of about 200ppm. In order to easily quantify this functional coating, nano silver was used. Nano silver is a collection of 250 nanoparticles of silver decomposed to a high purity of 99.99% silver by exploding through high voltage, so pure silver particles can be easily measured to obtain a uniform concentration ratio.

In order to liquefy pure silver ace, which is harmless to human body and has strong sterilization and antibacterial effect, it was carried out as follows.

After compressing the electric energy stored through the transformer at both ends of the silver wire, which is 99.99% purity, with a pulse, and applying a high-density current of 150,000 volts to the metal wire through a high voltage switch, an extremely high temperature plasma is generated. However, through the generated heat of resistance, silver was vaporized or ionized to obtain nanosilver particles decomposed to a size of 150nm-250nm.

In addition, the obtained nano silver particles were collected and dispersed in water to prepare an aqueous solution containing nano silver.

The nano silver obtained by the electroplasmic method is a colloidal silver solution obtained by the physical and chemical method of extracting by adding the existing ultra weak nitrate and caustic soda or the formalin-based preservative or organic antibacterial agent. It is a differentiated nano silver technology that uses pure silver in an environmentally friendly way, with strong sterilization and antibacterial action, while avoiding the hazards and potential environmental hazards of the pollutants inherent in the product.

Anion tourmaline minerals with large anions are added, and the characteristics and effects of anion minerals are well represented in Sungmun Chemical Dictionary (ed by Samkwang Printing Company). Among the Curie couples, who won the Nobel Prize for Physics in 1880, their husband, Pierre Curie, found out that with Jacques, he constantly released 0.06 m of weak currents in the tourmaline crystals. The present invention adds a powdered (350 mesh) tourmaline. To prepare a functional sterilization, deodorant to release a large amount of anions.                     

The water-soluble binder used in this functional paint is an aqueous solution mixed with 30% environmentally friendly acrylic emulsion binder and 30% non-toxic polyvinyl butyral. Especially, polyvinyl butyral is a polymer, hydroxyl group or aliphatic compound. It is a compound that is not reactive with adverse effects on inhalation, skin contact, eye contact, ingestion, and in the Occupational Safety and Health Regulation (MSDS) and is carcinogenic and hazardous risk = 0 in the classifications of the European Union and the United States Occupational Safety and Health. As a material, it is water-soluble and stable in physical properties, but has low mutual density, so it is used as an adhesive to attach charcoal and silver to the adhered surface by using polyvinyl butyral with gas permeability. Deodorizing power, which is a unique feature of charcoal, has a structure that allows harmful gas generated from building materials and living spaces to penetrate and adsorb into the pores of charcoal smoothly. I did not interfere.
