Abstract

The invention discloses a building exterior wall coating. The building exterior wall coating is composed of raw materials including, by weight part, 10-16 parts of waterborne acrylic resin, 6-10 parts of waterborne epoxy resin, 3-6 parts of sodium silicate, 25-34 parts of ceramsite, 4-8 parts of emery powder, 2-5 parts of gypsum powder, 0.5-2 parts of lignocellulose, 0.1-0.5 part of hydrophobic powder, 2-8 parts of titanium dioxide, 2-4 parts of dispersing agent, 15-25 parts of dimethylbenzene, 8-14 parts of duckweed, 5-12 parts of reed and 4-8 parts of shale. The invention also discloses a preparation method of the building exterior wall coating. The building exterior wall coating is extensive in raw material sources, simple in preparation process and applicable to large-scale industrial production; the raw materials can achieve synergistic effects, are high in application strength, waterproof performance and antibacterial effects, long in service life, free from fracturing, peeling, ageing and the like and capable of meeting the usage requirements of people.

Description

technical field [0001] The invention relates to a coating, in particular to an exterior wall coating for buildings. Background technique [0002] Paint, traditionally called paint in China. The so-called paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, oil, or emulsion, with or without adding pigments, fillers, adding Corresponding additives, viscous liquid prepared with organic solvent or talcum powder. Paint is a material that can be well bonded to the base material and form a complete and tough protective film on the surface of an object, called a paint. Paint and paint are the same concept. Paint is a customary name that people have used for a long time. After it was introduced into my country, it has been used in the construction industry. The function of coatings can be summarized into three aspects: protection, decoration and special functio...
