Problems solved by technology

Organic synthetic antifungal agents have disadvantages such as poor heat resistance, easy decomposition to produce harmful substances, poor safety, and strong pertinence.
At the same time, since the adhesive is often in contact with people during use, it will inevitably make people come into contact with the organic antifungal agent in it.
Because traditional organic antifungal agents have certain toxicity, long-term exposure will accumulate in the human body, which will cause harm to the health of the exposed users

Embodiment 1

[0021] Add 610g of tap water to the reaction kettle, start stirring, add 85g of polyvinyl alcohol, heat up to 95°C to dissolve for 1 hour, add 9.0g of hydrochloric acid and 17g of formaldehyde, and control the reaction temperature at 90-95°C. When separation (water separation) occurs, add sodium hydroxide solution (sodium hydroxide 3.2g, water 20g), adjust the pH value of the material to 6.0-7.0, cool down to 80°C, add urea aqueous solution (urea 4.0g, water 20g), Maintain the temperature of 80°C for 30 minutes; adjust the temperature to 80-85°C, add 90g of kaolin and 55g of light calcium carbonate, stir and disperse for 30 minutes, then add cornstarch milk (30g of cornstarch, 40g of water), disperse and gelatinize for 30 minutes Minutes, lower the temperature to 45°C, add 8.0g of plasticizer, 2.0g of inorganic nano antifungal agent, add 6.8g of water, continue to stir for 1-2 hours, and finally filter the material through a 60-mesh filter to obtain the product of the present i...

Abstract

The invention discloses a nano mildew-proof quick-drying white latex and preparing method thereof. The nano mildew-proof quick-drying white latex is constituted of polyvinyl alcohol, kaolin, light calcium carbonate, formaldehyde, sodium hydroxide, hydrochloric acid and inorganic nano mildew-proof material, and uses inorganic material of high proportioning and novel high technological inorganic sterilization mildew-proof material to increase adhesion strength, quick-drying property and mildew-proof capability of the white latex. By using property of separating out water at high temperature for polyvinyl alcohol formaldehyde solution, kaolin and light calcium carbonate can be directly added, and technique is simplified. The invention can be widely used for decoration project and firework pot adhesion.

Description

technical field [0001] The present invention relates to a kind of nano mildew-proof quick-drying white latex and its preparation method Background technique [0002] White latex is a kind of water-based adhesive with a large amount and a wide range of applications. It is mainly used as an adhesive in the production of wood furniture, home, shop or office decoration, paper processing and other occasions. CN1186089A discloses a water-resistant and frost-resistant white latex, which does not use the traditional raw material vinyl acetate, but uses polyvinyl formal, urea-formaldehyde resin, methyl cellulose, and modified starch as binders, and mixes a small amount of bentonite or light Made of calcium carbonate, which reduces the production cost of the product and makes the product have certain water resistance and frost resistance. However, traditional water-based adhesives often use organic synthetic anti-mold agents to prevent mildew during storage and use. Organic syntheti...
