Abstract

The invention provides an acrylic resin, which comprises acrylic acid copolymer, wherein the acrylic acid copolymer consists of structural units shown as I, II, III and IV. The invention also provides a preparation method of the acrylic resin. The method comprises a step of preparing the acrylic resin by polymerizing a monomer 1, a monomer 2, a monomer 3 and a monomer 4 under the action of an initiator. The invention also provides a paint, which comprises main resin, crosslinking resin, a solvent and an auxiliary agent, wherein the main resin is the acrylic resin. In an inorganic component organic material, the excellent flexibility of organic components and excellent rigidity of inorganic components are fully combined by acrylic acid, so that a paint film has excellent flexibility and better rigidity, and the scratch resistance of the resin is comprehensively improved.

Description

technical field [0001] The invention relates to an acrylic resin, a preparation method thereof and a paint containing the acrylic resin. Background technique [0002] Acrylic resin has the characteristics of light color, high transparency, bright and full, tough coating film, strong adhesion, corrosion resistance, etc., and is a commonly used coating material. Acrylic resin coatings are widely used in high-end consumer goods such as automobiles, especially in high-grade finish varnishes on the outer layers of automobiles. [0003] However, the lack of scratch resistance of acrylic paint can lead to defects such as loss of gloss and fogging of the paint film. At present, there are generally the following methods to make up for the above defects: 1. Add inorganic fillers, such as glass powder, etc., to enhance the scratch resistance of the outer layer of the paint film; 2. Add silicone additives to reduce the surface energy of the paint film to reduce friction Coefficient; 3...
