Controlling and deodorizing fungus production and reducing VOC {Controlling and deodorizing fungus production and reducing VOC}

The present invention relates to mold suppression (growth) and deodorization and a VOC reducer, and in detail, a mold removal process with a single-use mold suppression agent, a sodium hypochlorite (lax) neutralizer, and a VOC reducer mixed composition. This is to achieve deodorization (neutralization) of odors generated in the air, suppression of mold formation, and reduction of VOC all at once.

In everyday life, microorganisms such as bacteria and fungi are very numerous and diverse, and are widely distributed in the natural world such as soil, air, water, and seawater. Since it is possible, damage to human diseases caused by microorganisms, food spoilage, housing, clothing, and industrial products is a serious reality.

In particular, fungi grow vigorously in high-temperature and high-humidity areas, with an optimum temperature of about 30°C, among which there is Caethotherium (a type of mold) that grows best on meat in a refrigerator at 5-8°C. Some species grow only at 45-53 ° C. In particular, in the case of hot and humid summer, it lives well on shady walls, bathrooms, damp indoor walls, carpets, and the backs of paintings and calligraphy.

Such molds are not only not aesthetically pleasing, but the odors generated contaminate the air in the house, and in addition to symptoms such as headaches, allergic diseases, laryngitis, and eye problems, they adversely affect the bronchi, causing sinusitis or pneumonia, and may cause skin diseases. Since the occurrence of diseases caused by these fungi is mainly caused by fungal spores (or hyphae), various drugs for removing fungi have been developed and used.

On the other hand, looking at the conventional mold removal process, the mold is removed with a chlorine-based disinfectant, such as Rox, on the moldy area, and a neutralizer is sprayed on the moldy area to remove the odor (eg, lacquer odor) generated during the mold removal process. is removed, a mold inhibitor is sprayed to prevent mold from frosting (creation) again, and a VOC reducer is sprayed to reduce VOC.

Therefore, in order to achieve mold suppression, deodorization, and VOC reduction, the operator visits the same place 2 or 3 times and proceeds with the above work processes in sequence, which makes the work very cumbersome and takes too much time and money. There was a problem.

A commonly used fungicide is a representative chlorine-based disinfectant, Rox. The bleach exhibits strong antibacterial power because it exerts an antibacterial and deodorizing effect by oxygen generated from hypochlorous acid (HClO), but it gives users discomfort and anxiety about human safety due to the toxicity of chlorine gas generated during use, indoors They tend to be reluctant to use it in space.

The odor generated when using the lacquer is neutralized, added, polymerized, oxidized-reduction, hydrolyzed, etc., by using a substance highly reactive to antibacterial and odorous components to decompose antibacterial and odorous substances or change them into odorless compounds. It can be deodorized in a way.

The mold suppression and deodorization and VOC reducing agent of the present invention uses Rox, a chlorine-based disinfectant, to remove mold (occurrence, parasitic) on the surface of various objects, and then use it to remove mold on the surface of the object from which mold is removed. It is a composition that suppresses generation (occurrence, parasitic) of re-generation (occurrence, parasitic), deodorizes odor, and greatly reduces VOC.

The mold suppression and deodorization and VOC reducer of the present invention include a lacquer neutralizer that neutralizes and deodorizes the odor generated by lacquer used to remove mold, and a lacquer agent that is applied to the surface of an object to prevent the mold removed by lacquer from regenerating.

The EVA resin (ethylene-vinyl acetate copolymer) is a polymer obtained by copolymerizing ethylene and vinyl acetate monomers, and is also referred to as ethylene-vinyl acetate copolymer. As the content of vinyl acetate increases, the density increases, but the degree of crystallization decreases and flexibility increases. Low-content EVA is usually processed like low-density polyethylene and has excellent impact resistance (especially at low temperatures) and stress cracking resistance, so it is used for heavy packaging materials and adhesives for laminate films. It is used for the same purpose as soft vinyl chloride, such as molded products, agricultural films, and commercial stretch films. High-concentration EVA is also used as a raw material for adhesives.

Examples of the acrylic resin include polymers from esters such as acrylic acid and methacrylic acid. Polymers of methyl methacrylate (methyl methacrylate) are representative, colorless and transparent, and transmit light, especially ultraviolet rays better than ordinary glass (refractive index 1.49). It does not discolor even when exposed to the outdoors, has good chemical resistance, and has good electrical insulation and water resistance.

The EVA resin and the acrylic resin inhibit the generation of mold by adhering IPBC (3-lodo-2-propynylbutylcarbamate) powder dispersed in water to a film or film.

The lacquer neutralizing agent may be exemplified by hypo, and neutralizes and/or deodorizes odors generated from lacquer used to remove mold. The hypo is also called sodium thiosulfate. Colorless and transparent crystals, it is soluble in water and reacts with silver halide to form water-soluble complex salts. It is a compound with the chemical formula Na ₂ S ₂ O ₃ used in analytical reagents, mordants, photo fixatives, and chlorine removers. The aqueous solution is pH 6.5-8. Soluble in water.
