Cathode two-component electrophoretic paint with high salt spray resistance

Abstract

The invention discloses a cathode two-component electrophoretic paint with high salt spray resistance. The cathode two-component electrophoretic paint comprises monomers, an initiator, a solvent, a neutralizer and pigments and fillers, wherein the monomers comprise 601 resin, PAK-3 polyamide, 604 resin, 618 resin, single resin, polyether TED-28, an emulsifier and 20 # epoxy resin; the initiator comprises a TE-2 initiator, an MTE-12 initiator and an MTE-2 initiator, and the solvent comprises butanone, propylene glycol monomethyl ether, isopropanol, diethylene glycol butyl ether and propylene glycol phenyl ether. The invention relates to the technical field of paints. According to the cathode two-component electrophoretic paint with high salt spray resistance, the resin monomer and the initiator in the formula of the electrophoretic paint can be improved, the electrophoretic paint has better salt spray resistance, the purpose that all components in the electrophoretic paint can be fullymixed by separately and finely preparing the emulsion and the color paste and then mixing the emulsion and the color paste is well achieved, the salt spray resistance of the electrophoretic paint prepared from electrophoretic paint resin can be greatly improved, and the production quality of the electrophoretic paint is guaranteed.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a highly salt spray-resistant cathodic two-component electrophoretic paint. Background technique [0002] Electrophoretic paint, also known as electrophoretic paint, and many people still use the name "electrophoretic paint" instead of "electrophoretic paint". As the defects of conventional spraying continue to emerge, electrophoresis has become more and more popular. Electrophoretic paint has also begun to be continuously updated, from anodic electrophoretic paint to cathodic electrophoretic paint, from single-component electrophoretic paint to two-component electrophoretic paint, the development of electrophoretic paint has also promoted the development of electrophoretic coating, so that more products are no longer Instead of using spraying technology, electrophoresis is used. Electrophoretic coatings and coating methods have been industrially applied after the 1960s. Electro...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a high salt spray-resistant cathodic two-component electrophoretic paint, which solves the problem that the salt spray resistance performance of the existing electrophoretic coating resin is only at the general average level. It cannot achieve high salt spray resistance, and it cannot achieve better salt spray resistance by improving the resin monomer and initiator in the electrophoretic paint formula, and it cannot be separated by emulsion and color paste Fine preparation, and then mixed preparation, so that the components in the electrophoretic paint can be fully mixed, greatly reducing the quality of the electrophoretic paint production
