Problems solved by technology

[0002] At present, non-conductive primers are widely used on plastic substrates in the market. Traditional primers are generally sprayed by hand, which has low work efficiency, is not conducive to the coating of color paints and varnishes, and wastes the amount of paint used for top coats. Can cause leaks and color inconsistencies

Abstract

The invention relates to a conductive primer for electrostatic coating of plastic substrates and a preparation method thereof. The raw materials include 20-30 g of thermosetting acrylic resin, 10-20 g of thermoplastic acrylic resin, 20-40 g of conductive titanium white pigment and 0.3-2 g of carbon black pigment. , dispersant 1~3, solvent 5~10, substrate wetting agent 0.5~1, thermosetting acrylic resin, dispersant, 40~60wt% solvent, conductive titanium dioxide pigment, carbon black pigment and add them to thermoplastic acrylic after stirring and grinding The resin, the substrate wetting agent and the remaining solvent are uniformly mixed to obtain a conductive primer for electrostatic coating of plastic substrates. Compared with the prior art, the invention has the advantages of good applicability, can save 30% of paint consumption, prevent spray leakage and the like.

Description

technical field [0001] The invention relates to a conductive primer and a preparation method thereof, in particular to a conductive primer for electrostatic coating of plastic substrates and a preparation method thereof. Background technique [0002] At present, non-conductive primers are widely used on plastic substrates in the market. Traditional primers are generally sprayed by hand, which has low work efficiency, is not conducive to the coating of color paints and varnishes, and wastes the amount of paint used for top coats. Spray leaks and color inconsistencies can result. The invention provides a method for preparing a conductive primer for electrostatic coating of plastic substrates, which can save 30% of the paint consumption of the upper coating due to the principle of electrostatic adsorption; the invention ensures that the conductive titanium dioxide pigment is dispersed into fine particles Stability and miscibility of various components, the performance of the p...
