Abstract

The invention relates to an environmentally-friendly interior and exterior wall coating and a preparation method and a construction method thereof. The coating is prepared from the following raw materials in part by mass: 40-80 parts of aqueous solution of polyvinyl alcohol with concentration of 8-10 percent (mass), 20-40 parts of 80-120 mesh waste stone dust, 1-8 parts of aqueous solution of boride with concentration of1-3 percent (mass) and 0.05 part of mildew preventive P803. The waste stone dust is obtained by grinding and screening a waste acrylic plate. Major ingredients of the waste acrylic plate include polymethyl methacrylate, aluminum hydroxide and calcium carbonate. The preparation method is simple. During construction, the coating is coated twice, and then a borax aqueous solution with concentration of 1-3 percent (mass) is sprayed.

Description

technical field [0001] The present invention relates to an environment-friendly interior and exterior wall coating and its preparation method and construction method, more specifically, relates to an environment-friendly interior and exterior wall coating using waste materials from the production of acrylic plates as main raw materials, its preparation method and construction method. Background technique [0002] Acrylic sheet is a commonly used architectural decorative sheet, and its main components are polymethyl methacrylate, aluminum hydroxide, and calcium carbonate. Enterprises that produce acrylic sheets often generate a lot of waste, including discarded acrylic sheets. At present, it is treated as garbage, which not only pollutes the environment but also wastes useful substances in the acrylic sheet. Contents of the invention [0003] The first object of the present invention is to provide an environmentally friendly interior and exterior wall coating that can redu...
