Abstract

The invention discloses a water-based epoxy-modified acrylic resin and a preparation method thereof. The preparation of the water-based epoxy-modified acrylic resin adopts two different cross-linking methods to form a film. First, the double bond in the unsaturated fatty acid in the resin is used Carry out oxidative self-crosslinking; secondly, use crosslinking monomers (diacetone acrylamide and adipic hydrazide) to carry out inter-segment condensation reaction, and the prepared paint film has high crosslinking density, high hardness and good salt spray resistance. The present invention overcomes the deficiency of a single type of resin, inherits the common characteristics of epoxy and acrylic resin by modifying epoxy and acrylic resin, has excellent physical and mechanical properties, high solid content and low viscosity, and the comprehensive performance of the resin reaches Best, widely used in the field of automotive anti-corrosion coatings.

Description

technical field

[0001] The invention relates to the field of water-based coatings, in particular to a water-based epoxy-modified acrylic resin and a preparation method thereof. Background technique

[0002] With the continuous development of our country's economy and the continuous improvement of people's consumption level, automobiles, as an important means of transportation for people, have gradually entered every family. People's requirements for the quality of cars are also constantly improving, and the appearance level of the vehicle paint film plays an important role in people's purchase of cars. As an important supporting vehicle, the auto coating industry has also made great progress. In the developed countries of automobiles, the amount of automotive coatings occupies an extremely important position in the total output of coatings. Paint manufacturers in various countries attach great importance to the development of automotive coatings to meet the development need...
