Abstract

The invention provides a method for preparing a water dispersion type cathode epoxy electrophoretic paint. The electrophoretic paint is prepared from the following raw materials in parts by weight: 40-50 parts of water-soluble epoxy resin, 20 parts of water, 10 parts of kaolin, 5 parts of carbon black, 2 parts of a dispersant, 0.5 part of a defoaming agent and 0.3 part of a catalyst. The method comprises the following steps: introducing a hydrophilic group into a molecular chain of epoxy resin, dissociating kation from water, and carrying out dispersion emulsification to obtain water dispersion type epoxy resin; mixing and stirring the water dispersion type epoxy resin with the kaolin, the carbon black, the catalyst, the dispersant and the defoaming agent for a preset time to obtain uniform slurry; grinding the uniform slurry till a uniformly distributed particle size and preset fineness to obtain the electrophoretic paint. By adopting embodiments of the invention, the electrophoreticpaint which is good in water dispersibility can be prepared.

Description

technical field [0001] The application relates to the field of chemical technology, in particular to a preparation method of a water-dispersed cathodic epoxy electrophoretic coating. Background technique [0002] As a kind of coating, cathodic epoxy electrophoretic coating has been widely used in electrophoretic coating of automobile electrophoretic primer, hardware parts, machinery, metal components, etc. [0003] However, in the prior art, polyurethane coatings have poor water dispersibility and contain more VOCs components, which have certain safety pollution and harm to human body. [0004] There are at least the following problems in the prior art: polyurethane coatings have poor water dispersibility and contain a lot of VOCs, causing certain safety pollution and harm to the human body. Contents of the invention [0005] The purpose of the embodiment of the present application is to provide a method for preparing a water-dispersed cathodic epoxy electrophoretic coati...
