Problems solved by technology

However, due to cement shrinkage or improper construction and the performance of the exterior wall paint itself, the exterior wall of the building will have cracks, water seepage, and water leakage. It will lead to the peeling off of the exterior wall paint, causing a safety hazard

Abstract

The invention discloses a waterproof, water-resistant, anti-cracking and heat-insulating wall coating for building exterior walls and a preparation method. The wall coating is prepared from the following raw materials in parts by weight: 40-80 parts of a thermal insulation main material, 20-40 parts of asbestos powder, 3-5 parts of a film-forming agent, 4-10 parts of a hydrophobic thermal insulation material, 1-5 parts of an additive, 3-10 parts of polyanionic cellulose and 70-150 parts of deionized water. The exterior wall coating disclosed by the invention is made of a material with good thermal insulation property and has good thermal insulation property, so that the surface of the exterior wall of a building has a better thermal insulation function; the exterior wall coating disclosedby the invention has hydrophobic property itself rather than hydrophobic property only on the surface of the exterior wall coating, so that the exterior wall coating has good water resistance and waterproofness and also has good self-cleaning property, a coating film is hard and smooth, and dirt can be removed along with rainwater; and the asbestos powder exists in the form of fibers, so that theexterior wall coating has good crack resistance after film formation and drying.

Description

technical field [0001] The invention relates to a wall paint, in particular to a waterproof, water-resistant, crack-resistant, thermal-insulation wall paint for building exterior walls and a preparation method thereof. Background technique [0002] Exterior wall paint is a material that can be coated on the surface of the exterior wall of a building and can form a continuous film that is firmly attached. At the same time, it has a certain aesthetics. Exterior wall decoration is directly exposed to the natural environment and has been subjected to wind, rain and sun for a long time. Therefore, wall coatings are required to have water resistance, pollution resistance, aging resistance and good adhesion, as well as good freeze-thaw resistance. , Low film forming temperature and so on. However, due to cement shrinkage or improper construction and the performance of the exterior wall paint itself, cracks, water seepage, water leakage and other phenomena may occur on the exterio...
