Abstract

The invention discloses flame retardant coating for cars. The flame retardant coating for cars is prepared from the following raw materials in parts by weight: 20 parts of hydroxy acrylic resin, 10-30 parts of alkyd resin, 10-20 parts of trimethylolpropane triacrylate, 5-15 parts of etherified fluorocarbon resin, 5-20 parts of melamine polyphosphate, 5-15 parts of pentaerythritol, 5-15 parts of a foaming agent, 1-5 parts of pigments and 2-8 parts of pigments. The invention further discloses a preparation method of the flame retardant coating for cars. Compared with the prior art, the flame retardant coating for cars has relatively long fire-resistant time; and the internal structure of a carbide layer formed during combustion is thick, firm and compact, so that the flame retardant effect is obviously improved. And moreover, the discharge of the VOC (volatile organic compounds) is very small, and the environmental pollution is effectively reduced.

Description

technical field [0001] The invention relates to a flame-retardant automobile coating and a preparation method thereof, belonging to the field of chemical coatings. Background technique [0002] With the development of my country's automobile industry, the growth of automobile ownership has provided a huge market development space for my country's automobile coating industry. Automobile coatings refer to the coatings applied on the body and parts of various vehicles such as cars, and generally refer to coatings and auxiliary materials for new cars and coatings for vehicle repairs. Its main functions include: ① beautiful appearance. It is required that the paint film be full, the luster is gorgeous and soft, the sharpness of reflection is good, the colors are various and in line with the trend, so that the appearance looks more pleasing to the eye and gives people a sense of beauty; ②Excellent weather resistance and corrosion resistance, can be applied to various Temperature...
