Abstract

The present invention relates to an interior wall coat and its preparation method. Said interior cost is composed of ground coat, middle coat and external coat, and is characterized by that every layer of said coat contains its respective raw material composition and is made up by adopting a certain preparation process. Said coat is no-toxic, has no abnormal smell, has no radioactivity, contains no harmful substances of formaldehyde, etc. and has the features of resisting fungus, resisting damp, resisting corrosion, resisting smoke and steam, no scaling and seasily cleaning, and is suitable for brush-coating interior wall of color preparation workshop, Chinese medicine extraction workshop, Chinese medicinal material storehouse and color and oil-containing workshop of food industry.

Description

technical field [0001] The invention relates to a coating, in particular to an interior wall coating used in the pharmaceutical industry and the food industry. Background technique [0002] At present, most of the interior wall coatings used in the pharmaceutical industry and the food industry use paint or latex paint. During the painting process, the paint will release toxic and odorous organic solvent gas, and part of it will be absorbed by the wall. After the paint film is damaged, it will be released slowly, causing long-term pollution to the environment. Especially in the pharmaceutical industry, after the rough surface of Chinese medicinal materials absorbs these odors, it will affect the quality of the medicinal materials. Latex paint is too thin to withstand long-term corrosion and fumigation, and the paint surface cracks and falls off. It is difficult for the wall surface painted with the above-mentioned interior wall paint to meet the ...
