Abstract

The present invention relates to a coating. The invention discloses an interior wall paint and a preparation method thereof. The technical scheme adopted in the present invention is: a kind of interior wall coating, is made up of primer coating, middle coating, and outer coating, is characterized in that: described primer coating, middle coating, outer coating each contain the raw material of certain ratio Components; and prepared according to the prescribed process; the interior wall paint is used for the interior wall paint of the colored preparation room. The beneficial effect of the invention is that the preparation process is simple, and the prepared interior wall paint is non-toxic, odorless, radioactive, and harmful substances such as formaldehyde. And it has the characteristics of mildew resistance, moisture resistance, corrosion resistance, fumigation resistance, non-shedding and easy cleaning. It is especially suitable for interior wall painting of colored preparation workshops in the pharmaceutical industry, traditional Chinese medicine extraction workshops, Chinese herbal medicine warehouses, and colored and oily workshops in the 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 nation...
