Abstract

The invention discloses a paint, which is made of the following materials in parts by weight: 100-200 parts of acrylic modified resin latex, 10-15 parts of low-molecular-weight polyethylene, 10-20 parts of high-molecular-weight polyethylene, nanoelectric 10-30 parts of stone powder, 10-20 parts of nanometer far-infrared ceramic powder, 100-200 parts of pigment, 30-40 parts of dipropylene glycol methyl ether acetate, 10-20 parts of additives; among them, the solid content of acrylic modified resin latex It is 80-90%, adding a small amount of low-molecular-weight polyethylene and high-molecular-weight polyethylene to the coating of the present invention can combine with each other to improve the cold resistance of the coating, without cracking, impact resistance, and can reduce the heat absorption of the coating.

Description

technical field [0001] The invention relates to a coating and belongs to the technical field of coatings. 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 The corresponding additives are viscous liquids prepared with organic solvents or water. 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 thin film. The film formed in this way is commonly called coating film, also known as paint film or coating.” Due to the excessive surface tension of the current pain...
