Embodiment 1-3

[0027] Embodiment 1-3 comprises the following steps during the preparation of thin-type salt-spray-resistant automobile rust-proof epoxy primer:

[0028] (1) Take each raw material in proportion, mix and dissolve epoxy resin A, epoxy resin B, solvent A, and solvent B, add dispersant to disperse evenly, and add the following powders in sequence: ordinary coloring pigment, filler, antirust pigment A, anti-rust pigment B, anti-rust pigment C, anti-rust pigment D, anti-sedimentation agent, each powder needs to be dispersed evenly, then add salt spray agent, grind at 30-45°C, and finally add auxiliary The agent is dispersed until the fineness is not greater than 50 μm, and component A is obtained;

[0029] (2) Mix curing agent A, curing agent B, and solvent to obtain component B. Passed the inspection, component A and component B are packaged separately.

Abstract

The invention belongs to the technical field of automotive primers, and in particular relates to a thin salt-spray-resistant automotive rust-proof epoxy primer, which consists of component A and component B, and the weight part of component A is composed of: epoxy resin A13-18 4-8 parts of epoxy resin, 18-26 parts of solvent A, 9-13 parts of solvent B, 0.1-0.5 parts of dispersant, 8-15 parts of ordinary coloring pigments, 5-15 parts of fillers, 6-15 parts of antirust pigments , anti-rust pigment B12-18 parts, anti-rust pigment C5-10 parts, anti-rust pigment D5-10 parts, salt spray resistance 2-8 parts, anti-sedimentation agent 2-5 parts, additives 0.2-1 part; Part B consists of: 35-40 parts of curing agent A, 2-10 parts of curing agent B, and 40-60 parts of solvent. The primer prepared by the invention can improve the salt spray resistance of the product when the coating thickness is relatively thin.

Description

technical field [0001] The invention belongs to the technical field of automobile primers, and in particular relates to a thin salt-spray resistant automobile rust-proof epoxy primer and a preparation method thereof. Background technique [0002] The salt spray resistance of anti-rust primers used in automobiles is generally not ideal, and the effect of anti-rust and salt spray resistance can only be achieved when the coating film is thick. Although the effect of some imported products is relatively satisfactory, the price of imported products is high, and it is difficult for customers of low-end cars to accept and use them. Based on comprehensive market research, it is a current trend to research and develop a thin, salt-spray-resistant, anti-rust epoxy primer for automobiles with low cost and ideal effect. Contents of the invention [0003] The invention provides a low-cost thin salt-spray-resistant automobile rust-proof epoxy primer and a preparation method thereof. ...
