Abstract

The invention discloses an antibacterial wet-wiping-resistant interior wall coating. The coating comprises the following raw materials in parts by mass: 40-50 parts of styrene-acrylic emulsion, 0.5-1 part of acrylic emulsion, 12-18 parts of silica powder, 7-12 parts of titanium dioxide, 0.1-0.2 part of ethyl vanillin, 1-2 parts of Texanol ester alcohol, 0.2-0.5 parts of dispersant, 5-6 parts of polyethylene glycol 200, 0.1-0.2 part of antifoaming agent and 80-90 parts of deionized water, wherein the dispersant is one or two of HPMA (Hydroxypropyl Methacrylate) and zinc stearate, and the antifoaming agent is polyoxyethylene octylphenol ether. The interior wall coating disclosed by the invention is good in bacterial resistance, wet-wiping resistance and adhesion, and can be widely applied to various indoor coatings.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to an antibacterial and wet-scratch-resistant coating for interior walls. Background technique [0002] Interior wall decoration is an extremely important part of architectural decoration. Some inferior paints are used to paint interior walls, and the organic volatiles in them have a non-negligible adverse effect on human health. Healthy multi-functional coatings that are friendly to the environment and human body and have good performance are the development trend of coatings in the future. Existing interior wall coatings are of a great variety and have different functions, but their comprehensive properties still cannot meet the needs of use, and their performances often lose sight of one another. [0003] To sum up, how to overcome the deficiencies of the prior art has become an urgent problem to be solved in the field of existing coatings. Contents of the invention [000...
