Abstract

The invention relates to a high decorative coating for an outer wall and a preparation method of the high decorative coating. The high decorative coating comprises the following components in parts by mass: 20-30 parts of water, 0.4-0.8 part of an ethylene-vinyl acetate copolymer, 10-22 parts of calcite powder, 5-12 parts of anatase type TiO2 nanopowder, 3-9 parts of zinc oxide whiskers, 1-5 parts of sericite, 2-7 parts of kaolin, 0.3-0.7 part of dimethylsiloxane, 0.2-0.48 part of molecular sieve, 3-7 parts of succinimide, 0.1-0.3 part of 2-amino-2-methyl-1-propanol, 0.1-0.3 part of 2-ethyl hexyl acrylate, 0.15-0.45 part of tributyl tin chloride, 0.008-0.015 part of cumene hydroperoxide, 1-4 parts of propylene glycol, 0.7-3.2 parts of a self-crosslinking elastic acrylic emulsion and 30-44 parts of a silicone emulsion. The coating provided by the invention has an excellent decorative effect.

Description

technical field [0001] The invention relates to the technical field of decorative materials, in particular to a highly decorative coating for exterior walls and a preparation method thereof. Background technique [0002] At present, the surface building materials such as cement mortar and putty on the surface of the external wall will crack due to hydration and shrinkage, and the expansion coefficient of different materials will be different. Cracks appear in the surface coating, which not only affects the appearance of the building, but also may cause rainwater seepage leak. With the improvement of living standards, people have higher and higher requirements for architectural decoration coatings. Traditional coatings are poor in water resistance and antifouling. Once the wall has water seepage, the coating is easy to get wet, causing peeling and cracking. Moreover, if the wall is stained with stains, it is very troublesome to clean, and sometimes there is no way to clean i...
