Abstract

A method for preparing an antibacterial coating for a cable board in a clean area, comprising the following steps: (1) adding a silver-loaded calcium phosphate antibacterial agent to a modified solution, heating the modified solution to 65-70°C, and then heat preservation treatment After 60‑70min, cool to room temperature, obtain a precipitate after centrifugation, and dry the precipitate to obtain a modified silver-loaded calcium phosphate antibacterial agent; (2) water-based hydroxyacrylic acid emulsion, modified silver-loaded calcium phosphate antibacterial agent, 1 , After 2-cyclohexanediaminetetraacetic acid, tetrapolyethylene glycol monooctyl ether, dicyandiamide, and polycaprolactam powder are mixed evenly, an antibacterial coating for a clean area cardboard is prepared. The preparation method of the antibacterial coating for the cable board in the clean area provided by the present invention is simple in operation and low in cost. The prepared antibacterial coating has a high bactericidal rate, and has excellent adhesion on the surface of the cable board, and is not easy to fall off. Phenomenon.

Description

technical field [0001] The invention belongs to the technical field of preparation of antibacterial coatings, and in particular relates to a preparation method of antibacterial coatings for cable boards in clean areas. Background technique [0002] Carso panels are made of silicate, quartz, calcium oxide, natural organic fibers and selected mineral fillers through pressure molding and steam curing. The surface is a cold porcelain veneer with excellent weather resistance. Caso board has low thermal conductivity, the same as ceramic tiles, good energy-saving effect, high surface hardness, strong scratch resistance and impact resistance. Construction is convenient. Non-flammable and waterproof. Rich in color, the color is not affected by ultraviolet rays and organic chemical agents. It is easy to transform and will not cause secondary pollution in the operating room caused by welding and spraying. No problems of cracking and peeling, rusting etc. At present, the walls of s...
