Abstract

The invention relates to a polyvinyl acetate building coating which is prepared from the following raw materials in parts by weight: 100 parts of polyvinyl acetate emulsion, 1 to 3 parts of hydroxypropyl methyl cellulose, 5 to 15 parts of acetate fibers, 8 to 10 parts of methyl alcohol, 1 to 10 parts of silicone oil, 2 to 6 parts of paraffin, 60 to 80 parts of deionized water, 10 to 15 parts of propylene glycol monomethyl ether, 10 to 20 parts of defoaming agent, 30 to 40 parts of dichloromethane, 15 to 25 parts of ethylene glycol, 15 to 25 parts of sodium hydroxide, 4 to 8 parts of plasticizer, 15 to 35 parts of lime, 2 to 8 parts of tributyl phosphate and 10 to 30 parts of xylene. The viscosity of the building coating is between 45s and 55s; the bonding strength of the building coating is between 30MPa and 40 MPa; the surface of the building coating is dried within 20 to 40 minutes; and the building coating is completely dried within 18 to 20 hours. The building coating cannot be blistered and desquamated after being soaked in water for 20 to 30 days. A coating film is resistant to scrubbing, namely, the coating film can be scrubbed for 2800 to 3000 times. Thus, the building coating can be widely produced and continuously used for replacing the existing material.

Description

technical field [0001] The application belongs to the field of coatings, in particular to a polyvinyl acetate architectural coating. 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, or oil, or emulsion, with or without adding defoaming agent, filler , add corresponding additives, and prepare viscous liquid with organic solvent or silicone oil. The relatively authoritative book "Painting Technology" in the Chinese coatings industry defines it as follows: "Painting is a material that can be coated on the surface of an object by different construction techniques to form a firm adhesion, a certain strength, and a continuous coating. Solid film. The film formed in this way is commonly called a coating film, also known as a paint film or a coating." The material coated ...
