Abstract

The invention discloses a waterproof and wear-resistant composite coating for buildings and a preparation method thereof. The waterproof and wear-resistant composite coating is prepared from the following raw materials in parts by weight: 25 to 35 parts of maleic anhydride modified rosin glyceride, 20 to 30 parts of epoxy acrylic resin, 18 to 25 parts of portland cement, 10 to 15 parts of polyurethane rigid foam powder, 15 to 20 parts of trimethylol triacrylate, 10 to 15 parts of modified nano-silica, 10 to 15 parts of water-based silicone-acrylic emulsion, 15 to 25 parts of asphalt, 2 to 4 parts of calcined kaolin, 5 to 8 parts of additive, 3 to 6 parts of filler, 4 to 6 parts of modified nano slurry, and 2 to 5 parts of cellulose ether thickener. The coating for buildings prepared from the maleic anhydride modified rosin glyceride, epoxy acrylic resin, portland cement, polyurethane rigid foam powder, trimethylol triacrylate, modified nano-silica, water-based silicone-acrylic emulsion, asphalt, and calcined kaolin according to an effective ratio has excellent weather resistance and strong acid and alkali resistance, which are greatly improved compared with the thermal insulation coatings sold in the general market; and the anticorrosion performance is good, and the preparation method is simple.

Description

technical field [0001] The invention relates to the technical field of architectural paint production, in particular to a waterproof and wear-resistant architectural composite paint and a preparation method thereof. Background technique [0002] With the rapid development of social production, energy and the environment have become two major issues that the whole society pays more and more attention to, thus putting forward higher requirements for energy saving and environmental protection. Today, the world is generally facing the crisis of increasing energy shortage. In order to reduce energy consumption, people have put forward higher requirements on the efficiency of energy use in all aspects of social production and life. Among them, in the construction field, energy-saving buildings are an effective way to improve the energy efficiency of buildings. [0003] Architectural coatings are a kind of coating products used for house decoration. Some buildings have special r...
