Description

Functional paint made with nano silver and charcoal

The present invention relates to a functional paint prepared using nano silver and charcoal.
In general, charcoal is produced at a high temperature of more than 1200 degrees Celsius, and is used for purifying and purifying water by using charcoal powder crushed to various sizes as well as deodorization using pores of the 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.

This is because the 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 sudden dropping side effect appears, the hassle of washing and drying with water in order to discard it or to separate the bacteria is generated.

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.

The present invention is to solve the above problems.
In order to achieve the above object, in the present invention, charcoal, nano silver and anion stone minerals are used as main raw materials for deodorization, air purification, and various bacteria of harmful components such as harmful gases or odors generated in various buildings and furniture in our daily lives. It is intended to provide an environmentally friendly functional water-based paint that exhibits excellent removal efficiency such as sterilization and deodorization.
When the paint of the present invention is applied to indoor buildings and dried, the air purification, antibacterial action, anion emission, far infrared ray emission, warm blood action, etc. are performed by the action and effect of the functional materials added with charcoal and nano silver as the main raw materials. By eliminating harmful gases generated in buildings, purifying the air, and adsorbing and sterilizing suspended bacteria in the air, we can provide our living space as a safer and more comfortable space.

The present invention provides a functional paint that effectively sterilizes bacteria adsorbed in pores with air purification by using strong sterilizing properties of charcoal powder and nano silver having a deodorizing power with a porous structure.

Use charcoal powder pulverized to have a size of 325 mesh activated charcoal or true charcoal produced at a high temperature of more than 1200 degrees Celsius.
At this time, the charcoal powder as the main component of the charcoal itself of carbon does not generate mold, but due to the porous structure of the charcoal, various gases and various organic compounds are naturally adsorbed.

A large number of molds feeding the adsorbed organic materials may occur in the pores of the char. At this time, bacteria and molds that feed the organic substances adsorbed in the pores are generated, causing bacteria to multiply in the pores of the char. Due to decay, the deodorizing performance, which is a unique feature of charcoal, is markedly degraded. In order to effectively remove these bacteria, charcoal needs to be treated with antibacterial treatment.

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 water vein blocking effect, and is harmless to human body.

In general, in order to have antibacterial activity against various bacteria through silver, it is necessary to secure a silver ion concentration of about 200 ppm. In order to easily quantify this functional coating, nano silver is used.
Nano silver is a collection of 250 nanoparticles of silver decomposed to a high purity of 99.99% of silver, which is generated when exploding through high voltage. 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 (99.99% purity), the anode with pulse, and applying high density current of 150,000 volts to the silver wire momentarily through the high voltage switch, the plasma is in extremely high temperature state. Will occur.
Through the generated resistance heating, the silver is vaporized or ionized to obtain nano silver particles decomposed to a size of 150 nm to 250 nm.

In addition, the obtained nano silver particles are 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 as a powerful way of sterilizing and antibacterial, 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 in 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. To prepare a functional sterilization, deodorant to release a large amount of anions.

The water-soluble binder used for this functional paint uses the aqueous solution which stirred and mixed the acrylic emulsion binder and the polyvinyl butyral which was made into aqueous solution, mutually.
At this time, the above-mentioned acrylic emulsion has a concentration of 30%, and the polyvinyl butyral concentration is also used as an aqueous solution at 30%.
At this time, the polyvinyl butyral is a polymer, a hydroxyl group, and an aliphatic compound, and has no side effect and reactivity with inhalation, skin contact, eye contact, ingestion, etc. in the Industrial Safety and Health Regulation (MSDS). The carcinogen and the US Occupational Safety and Health Administration have also classified the charcoal and silver by using polyvinyl butyral with gas permeability due to its stable water solubility and adhesion but low mutual density. It is used as an adhesive to adhere to the adhered surface to secure the porosity of charcoal, so that harmful gas generated in various indoor building materials and living spaces can be easily penetrated and adsorbed into the pores of charcoal. Did not inhibit.

Examples of application of the present functional nano silver and charcoal paints synthesized and mixed with each material are as follows.
