Problems solved by technology

[0002] The cathodic electrophoretic paint color paste is mixed with the cathodic electrophoretic paint emulsion to make the cathodic electrophoretic paint. The existing cathodic electrophoretic paint emulsion is generally toxic, the flatness is too low, and the stain resistance is poor, so the performance of the cathodic electrophoretic paint produced is poor.

Abstract

The invention provides a cathode electrophoresis paint emulsion which is prepared from the following raw materials in percentage by mass: 25-40% of bisphenol A solid epoxy resin, 10-20% of 2,6-diethylaniline, 10-15% of EB curing paint, 2-4% of polyurethane catalyst, 1-2% of emulsion tackifier, 15-30% of polypropylene, 10-20% of deionized water and 10-20% of acid. The preparation method comprises the following steps: a. adding the bisphenol A solid epoxy resin, EB curing paint and 1 / 2 of deionized water into a reaction kettle, heating to 110-120 DEG C, completely dissolving by stirring, cooling to 80 DEG C below, adding the 2,6-diethylaniline, slowly heating to 100-115 DEG C, and keeping the temperature for 1.5 hours. The cathode electrophoresis paint emulsion has the advantages of reasonable proportioning and better antiseptic effect; and the produced product has the advantages of smooth surface, high safety, environment protection, favorable pollution resistance and favorable spraying effect.

Description

Technical field [0001] The invention relates to the field of electrophoretic paint production, in particular to a cathodic electrophoretic paint emulsion and a preparation method thereof. Background technique [0002] The cathodic electrophoretic paint color paste is mixed with the cathodic electrophoretic paint emulsion to make the cathodic electrophoretic paint. The existing cathodic electrophoretic paint emulsion is generally toxic, has too low flatness and poor stain resistance, so the produced cathodic electrophoretic paint has poor performance. Summary of the invention [0003] In view of the above problems in the prior art, the present invention provides a cathodic electrophoretic coating emulsion and a preparation method thereof. The surface of the product is relatively flat, safe and environmentally friendly, and has good stain resistance. [0004] The present invention is realized through the following technical solutions: [0005] A cathodic electrophoretic coating emulsio...
