Coating for concrete wall surface

Abstract

The invention belongs to the technical field of coatings and relates to a coating for a concrete wall surface. The coating comprises the following raw materials in parts by weight: 20-30 parts of emulsion binder, 6-16 parts of titanium dioxide, 4-8 parts of talcum powder, 10-15 parts of barium sulfate, 2-3 parts of glycol, 0.3-0.5 part of tributyl phosphate, 0.1-0.3 part of sodium hexametaphosphate, 0.15-0.25 part of emulsifier OP-10, 0.1-0.2 part of carboxymethylcellulose, 0.1-0.3 part of sodium polymethacrylate, 0.2-0.4 part of phenyl mercuric acetate, 0.1-0.3 part of terpilenol, 3-6 parts of zinc oxide, 5-15 parts of calcium carbonate, 3-5 parts of environment-friendly glue with a market sold number 805, 20-30 parts of tap water, purified water or distilled water and the balance of ammonia water. The coating has the major advantages of wide raw material source, simple and convenient formulation and firm binding to the concrete wall surface.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a coating suitable for coating rough walls such as concrete. Background technique [0002] Coatings have been widely used in the construction and decoration industries. However, during use, it was found that the coating layers of existing commercially available coatings on rough walls such as concrete are not firm and cannot withstand wind and rain. Usually, within 3-5 years Just have different degree come off, have influenced the outward appearance of building on the one hand, on the other hand, have caused great hidden danger to safety. Contents of the invention [0003] In order to solve the above-mentioned problems, the purpose of the present invention is to disclose a kind of coating that is used for the concrete wall surface, and it can firmly adhere to the wall surface for a long time, and it adopts the following technical scheme to realize. [0004] A coating for conc...
