Problems solved by technology

[0003] With the progress of the times, after long-term education and guidance to consumers, consumers' awareness of environmental protection home decoration and healthy home is increasing, and the potential market demand for environmental protection coatings will increase rapidly. At present, various environmental protection coatings Emerging in endlessly, manufacturers attract the attention of consumers in terms of color, material and safety, and most of their prices are relatively expensive
In addition to being expensive, the existing environmentally friendly coatings often have some technical defects, such as poor adhesion, easy to fall off, poor weather resistance and stability, prone to mildew or oxidation, poor water resistance, and easy to mold due to humid air Phenomenon, especially during the rainy season in the south, the air is more humid, and mold is more likely to appear on the inner wall, which brings a lot of inconvenience to consumers
In addition, most of the existing paint products contain certain harmful substances such as formaldehyde and volatile organic compounds. Usually, it takes a long time to ventilate for normal use after use, and some paints contain formaldehyde and other harmful substances. It is easy to volatilize, and the environmental protection performance is very poor. It is easy to bring lasting harm to people's body in this environment for a long time

preparation example Construction

[0019] In the present embodiment, the preparation method of described coating comprises the following steps:

[0020] a. Grinding pyrophyllite and zinc oxide into fine powder, then uniformly mixing with nano-attapulgite, nano-kaolinite, shell powder, nano-titanium oxide, sepiolite powder and air-purifying sterilizing powder to prepare mixed powder;

[0021] b. Mix 2 / 3 volume of deionized water with polyvinyl alcohol, stir and heat up to 90°C. After the polyvinyl alcohol is completely dissolved, cool down to room temperature, add polyacrylate emulsion and epoxy resin, and heat at 300r / min Stir at least 45min at the stirring speed, then add polyacrylamide, mineral oil defoamer, polyacrylate ammonium salt dispersant, carboxymethyl cellulose, coconut oil, remaining deionized water and the mixture prepared in step a powder, and stirred at a stirring speed of 1000r / min for 10 hours; it is conducive to better dispersion of various raw materials, better compatibility, and better syner...

Abstract

The invention provides a mildew-proof and bactericidal environmental friendly coating. The coating comprises the following components in parts by weight: 25-32 parts of polyvinyl alcohol, 15-18 partsof a polyacrylate emulsifier solution, 8-10 parts of nano attapulgite, 11-13 parts of nano kaolinite, 8-10 parts of pyrophyllite, 12-15 parts of shell powder, 1.2-1.5 parts of zinc oxide, 0.8-1 part of polyacrylamide, 6-8 parts of epoxy resin, 0.7-1.0 part of a mineral oil defoaming agent, 0.5-0.8 part of nano titanium oxide, 10-12 parts of gas cleaning bactericidal powder, 3-5 parts of sepiolitepowder, 0.2-0.3 part of a polyacrylate ammonium salt dispersing agent, 0.1-0.2 part of carboxymethylcellulose, 3-5 part of coconut oil and 50-60 parts of deionized water. The gas cleaning bactericidalpowder is formed by pulverizing dry wormwood, cape jasmine, lemon-scented gum leaves, Eucalyptus Gunnii leaves and lemon-grass according to the mass ratio of 3: 1: 1: 2: 1, and then mixing the foregoing components.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a mildew-proof and bactericidal environment-friendly coating. Background technique [0002] At present, indoor air pollution mainly comes from five aspects: one is human breathing and smoke; the other is formaldehyde, ammonia, benzene, toluene, etc. in decoration materials; the third is microorganisms, viruses, and bacteria; the fourth is kitchen fume; The fifth is air-conditioning syndrome. These pollutants enter the human body with breathing and accumulate for a long time, seriously endangering people's health. [0003] With the progress of the times, after long-term education and guidance to consumers, consumers' awareness of environmental protection home decoration and healthy home is increasing, and the potential market demand for environmental protection coatings will increase rapidly. At present, various environmental protection coatings Emerging in endlessly, manufactu...
