Problems solved by technology

[0002] In the field of auto parts coating, mechanical spraying is becoming more and more popular at present. Many plastic parts with complex shapes have also begun to be mechanically sprayed. The general nylon plastic primer is two-component, so the conductive primer used in mechanical spraying is also two-component. components, because generally one-component primers have poor adhesion
However, mechanical spraying is pipelined to transport paint, and the use of two-component paint is easy to block the pipeline, which is inconvenient for construction

Abstract

The invention relates to a preparation method for single-component nylon plastic conductive primer. The single-component nylon plastic conductive primer is prepared by mixing the following components in part by weight: 30 to 60 parts of thermoplastic acrylic resin or polyester resin, 20 to 30 parts of conductive titanium dioxide, 0.2 to 0.8 part of conductive graphite, 0.1 to 1.0 part of conductive carbon black, 3 to 8 parts of cellulose acetate butyrate, 20 to 40 parts of solvent, 2 to 6 parts of dispersing agent, 2 to 8 parts of adhesion promoter and 1 to 7 parts of anti-settling wax slurry. Compared with the prior art, the preparation method for the single-component nylon plastic conductive primer is applicable to mechanical spraying construction and is convenient in construction and good in adhesive force. In addition, a curing agent does not need to be added and the cost is lower than that of a double-component product.

Description

technical field [0001] The invention relates to a preparation method of a conductive primer, in particular to a preparation method of a one-component nylon plastic conductive primer. Background technique [0002] In the field of auto parts coating, mechanical spraying is becoming more and more popular at present. Many plastic parts with complex shapes have also begun to be mechanically sprayed. The general nylon plastic primer is two-component, so the conductive primer used in mechanical spraying is also two-component. Components, because generally one-component primers have poor adhesion. However, mechanical spraying is pipelined to transport paint, and the use of two-component paint is easy to block the pipeline, which is inconvenient for construction. The invention discloses a preparation method of a one-component nylon plastic conductive primer. This one-component conductive primer has excellent adhesion on nylon substrates and excellent conductivity after film formati...
