Problems solved by technology

The former needs to be pasted with fiberglass cloth and scraped for many times before use, the construction is complicated and the project period is long; while the latter also needs to be scraped before use, and then apply latex paint after drying.
The surface of the wall treated by the above method is not smooth, the coating is thin, and it is easy to crack, peel off and powder off after long-term use, and it is difficult to meet the cleanliness requirements of the national standard for clean rooms required by the pharmaceutical, electronic and food industries.
There are also many reports on interior wall coatings in Chinese patents. Although their products have certain properties and effects of acid and alkali resistance and cleanability, they are powerless to corrosive organic solvents.

Embodiment Construction

[0041] Best practice:

[0042] Weigh 8kg of polyvinyl alcohol, 0.07kg of carboxymethyl cellulose, 0.03kg of hydrochloric acid, 0.08kg of formaldehyde, and 16kg of silica sol, make liquid according to the existing polyvinyl formal method, and then add 0.02kg of urea to the liquid And sodium benzoate 0.25kg, make matrix material A component. Stir the above liquid evenly, make the urea react with the free formaldehyde in the liquid, make it aminated to form urea-formaldehyde resin, so as to improve the bonding performance of the matrix. The added sodium benzoate can be used as a preservative and antifungal agent for this component. The silica sol in the liquid is used to improve the water resistance, fire resistance and pollution resistance of the coating. Weigh 80kg of calcium carbonate, 10kg of active calcium, 25kg of calcium hydroxide, 6kg of silicon dioxide, 6kg of magnesium oxide, and 5kg of silicon magnesium hydroxide, mix the above materials evenly, and grind them into p...

Abstract

An organic corrosion resistant paint for internal wall is composed of matrix A and inert material B. Its advantages are high decorative effect, smooth surface of wall, no poison and radioactivity, and high resistance to acid, alkali and organic solvent.

Description

Technical field: [0001] The invention relates to an anti-organic corrosion interior wall paint, in particular to a clean interior wall paint used in pharmaceutical, food and electronic industries. Background technique: [0002] At present, most of the paints used in the treatment of clean room walls in pharmaceutical factories use epoxy resin or latex paint. The former needs to be pasted with glass fiber cloth and scraped for many times before use, which is complicated in construction and has a long project period; while the latter also needs to be scraped before use, and then apply latex paint after drying. The surface of the wall treated by the above method is not smooth, the coating is thin, and it is easy to crack, peel off and powder off after long-term use, and it is difficult to meet the cleanliness requirements of the national standard for clean rooms required by the pharmaceutical, electronic and food industries. There are also many reports of interior wall coating...
