Abstract

The invention discloses an interior wall coating, and a preparation method thereof. The interior wall coating is composed of a bottom layer coating, a middle layer coating, and an external layer coating at a certain ratio through specific technology, and is used for colored preparation chambers. The beneficial effects are that: the preparation method is simple; the obtained interior wall coating is nontoxic; no special smell is detected; no radioactivity is caused; no toxic substance such as formaldehyde is contained; mildew resistance, moisture resistance, corrosion resistance, fumigating resistance, and anti-shedding performance are achieved; cleaning is convenient; and the interior wall coating is especially suitable for coating of interior walls of colored preparation workshops, traditional Chinese medicine extraction workshops, and traditional Chinese medicinal material warehouses in pharmacy industry, and colored preparation, oil-containing workshops in food industry.

Description

Technical field [0001] The invention relates to a paint, in particular to an interior wall paint used in the high-standard sanitary industry. Background technique [0002] At present, the interior wall coatings used in the pharmaceutical industry and the food industry mostly use paint or latex paint. The paint releases toxic and odorous organic solvent gas during the painting process, 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, the rough surface of Chinese medicinal materials absorbs these odors, which will affect the quality of the medicinal materials. Latex paint is too thin to withstand long-term corrosion and fumigation, and cracks and peeling of the paint surface occur. The walls painted by the above-mentioned interior wall paints are difficult to meet the national hygiene regulations for the pharmaceutical industry and fo...
