Problems solved by technology

[0003] However, during the use of gypsum products, if they come into contact with water or in a dark and humid environment, the surface is prone to mildew.
The mold of gypsum products is due to the fact that gypsum itself is a material containing certain nutrients. Most of the mold of gypsum products is caused by moisture. Moldy gypsum products will greatly affect their durability and aesthetics. Moldy gypsum products are not suitable for continued use

Embodiment 1

[0055] The gypsum composite antifungal agent with waterproof function is composed of the following components in mass fractions: 4 parts of inorganic antibacterial components, 4 parts of chitosan, 5 parts of sodium methyl silicate, 13 parts of silicon acrylic emulsion, and 1.5 parts of sodium bicarbonate 1 part of sodium lauryl sulfate. The inorganic antibacterial components include 1 part of nano-silver, 1 part of borax, 2 parts of nano-titanium dioxide, and 12 parts of montmorillonite.

Embodiment 2

[0057] The gypsum composite antifungal agent with waterproof function is composed of the following components in mass fractions: 3 parts of inorganic antibacterial components, 3 parts of chitosan, 3 parts of sodium methyl silicate, 4 parts of silicon acrylic emulsion, lauryl sulfuric acid Sodium 0.1 part, sodium bicarbonate 0.2 part. The inorganic antibacterial components include 1 part of nano-silver, 1 part of borax, 1 part of nano-titanium dioxide, and 6 parts of montmorillonite.

Embodiment 3

[0059] The gypsum composite antifungal agent with waterproof function is composed of the following components in mass fractions: 8 parts of inorganic antibacterial components, 8 parts of chitosan, 7 parts of sodium methyl silicate, 14 parts of silicon acrylic emulsion, anhydrous dihydrogen phosphate 2 parts sodium, 1 part sodium lauryl sulfate. The inorganic antibacterial components include 2 parts of nano-silver, 1 part of borax, 5 parts of nano-titanium dioxide, and 40 parts of montmorillonite.

Abstract

The invention discloses a preparation and an application method of a gypsum composite antifungal agent with waterproof function, comprising the following components in parts by weight: 3-8 parts of inorganic antibacterial components, 3-8 parts of chitosan, methyl silicon 3-7 parts of sodium, 4-14 parts of silicone-acrylic emulsion, 0.2-2 parts of pH adjuster, 0.1-1 part of sodium lauryl sulfate. On the one hand, the compounding of chitosan and inorganic antibacterial components can effectively eliminate mold; on the other hand, the waterproof component is used to effectively avoid the easy formation of an environment suitable for mold survival inside the gypsum; the pH regulator can inhibit the survival of most bacteria, Improve the quality of film formation; the use of sodium dodecyl sulfonate can make the waterproof components and antibacterial components evenly dispersed in the gypsum, improve the anti-mildew performance of the gypsum and can reach grade 0, with a hydrophobic effect, and the saturated water absorption rate is lower than that of ordinary gypsum 5 times or more, and the softening coefficient reaches 0.86 or more. The preparation and application method is simple and easy to operate, so that the gypsum can be used in the kitchen, bathroom, outdoor and other areas prone to moisture, and the application range of the gypsum product is widened.

Description

technical field [0001] The invention relates to the preparation and application method of a gypsum composite antifungal agent with waterproof function, and belongs to the technical field of preparation of antifungal agents for building materials. Background technique [0002] Building gypsum products are a kind of material made of building gypsum as the main raw material. They have the advantages of light weight, fire prevention, heat insulation, good processing performance, and unique "breathing effect", which makes building gypsum widely respected by the construction industry. [0003] However, during the use of gypsum products, if they are exposed to water or in a dark and humid environment, the surface is prone to mildew. The mold of gypsum products is due to the fact that gypsum itself is a material containing certain nutrients. Most of the mold of gypsum products is caused by moisture. Moldy gypsum products will greatly affect their durability and aesthetics. Moldy gyp...
