Abstract

The invention discloses a high temperature resistant cathode electrophoretic coating and a preparation method thereof. The coating is prepared from color paste, emulsion and deionized water in a massratio of 1:(3-5):(4-6), wherein the color paste is prepared from the following components in parts by mass: 20-40 parts of acrylic modified cationic organic silicon resin, 3-10 parts of environment-friendly co-solvent, 0.5-5 parts of a neutralizing agent, 0.05-0.8 part of surfactant, 30-45 parts of deionized water and 25-35 parts of color filler; and the emulsion is prepared from the following components in parts by mass: 25-35 parts of acrylic modified cationic organic silicon resin, 1-5 parts of an emulsifying agent, 0.5-5 parts of a neutralizing agent and 35-55 parts of deionized water. Thehigh temperature resistant cathode electrophoretic coating has good high temperature resistance, high throwing power, high hardness, strong adhesive force, excellent chemical corrosion resistance, has low content of VOC, is safe and environment-friendly, and has a relatively high practical value.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-temperature-resistant cathodic electrophoretic coating and a preparation method thereof. Background technique [0002] Electrophoretic coating is a water-soluble organic coating with positive or negative charges, which is uniformly dispersed in aqueous solution at a relatively dilute concentration, and the conductive workpiece (coated object) is used as the cathode (or anode). The metal plate or carbon plate is used as the anode (or cathode), and under certain process conditions, a direct current is passed between the two electrodes, so that the electrophoretic coating is evenly deposited on the workpiece to form a water-insoluble organic coating film. After drying and curing at a certain temperature, an organic coating film with high hardness is obtained, which plays the role of anti-corrosion and surface decoration. [0003] Cathodic electrophoretic coatings have attra...
