Abstract

The invention discloses a high-performance water-based epoxy resin automobile paint and a preparation method thereof. The automobile paint comprises the following components in parts by weight: 30-60 parts of component A and 30-90 parts of component B. The component A comprises 30-60 parts of epoxy resin M, 1-10 parts of emulsifier X, 1-10 parts of cosolvent and 30-60 parts of deionized water. The component B comprises 0-30 parts of pigment, 10-30 parts of amine curing agent, 30-60 parts of deionized water, 0.1-3 parts of organosilicon leveling agent, 0.1-3 parts of polylol wetting agent, 1-5 parts of dispersing agent, 0.1-2 parts of preservative, 0.5-2 parts of emulsifier Y, 0.2-2 parts of pH regulator and 0.2-2 parts of defoaming agent. The whole paint uses water as the medium and only needs a small amount of cosolvent, so the VOC (volatile organic compound) content is greatly lowered, and the environmental pollution is small. The phase-reversal method used for preparing the water-based epoxy resin emulsion directly adopts mechanical dispersion without chemical reaction, and thus, has the advantages of simple equipment and low cost.

Description

technical field [0001] The invention relates to the field of chemical materials, in particular to a high-performance water-based epoxy resin automotive coating and a preparation method thereof. Background technique [0002] Due to its high chemical stability, corrosion resistance, good adhesion and mechanical properties, epoxy resin is widely used in construction, shipbuilding, automobiles, aerospace, machinery manufacturing, chemical building materials and other fields, especially in coatings It is more widely used in the industrial field. However, most epoxy coatings are solvent-based at present. With the development of society and the improvement of environmental protection awareness, people's requirements for chemical products are becoming more and more stringent. The coating industry is developing in the direction of high efficiency, energy saving, and ecology. [0003] The automobile industry is one of the four pillar industries in my country, and the demand for autom...
