Abstract

The invention discloses a foaming prime coating for automobiles. The foaming prime coating is prepared from the following components in percentage by mass: 10-20 percent of polyvinyl chloride, 20-30 percent of diisononyl phthalate, 40-50 percent of inorganic filler, 5-10 percent of modified polyamide, 3-5 percent of modified calcium oxide, 1-3 percent of a liquid stabilizer and 1-3 percent of a microsphere organic foaming agent. The foam prime coating is prepared from modified polyamide, modified calcium oxide, liquid stabilizer and other components, has few toxic volatile organic compounds, and can meet environment-friendly requirement.

Description

technical field [0001] The invention relates to the field of primers, in particular to a foamed primer for automobiles. Background technique [0002] Generally speaking, the surface of most automobile chassis and wheel covers is coated with primer, which plays the role of waterproof, anti-stone impact, anti-rust, and noise reduction. The original primer has a higher density after drying, which increases the weight of the car body. , in order to achieve the purpose of reducing the weight of the car body, the automobile factory adopts foamed primer. Weight, so as to achieve the purpose of reducing the weight of the vehicle body. [0003] The primer currently used contains a large amount of toxic volatile organic compounds, which is harmful to the human body and does not meet the environmental protection requirements. Volatile organic compound (VOC): refers to a class of organic compounds that exist in the air in the form of vapor at room temperature with a boiling point rang...
