Epoxy grafted acrylate self-layering connecting paint and preparation method thereof

Abstract

The invention relates to the technical field of antifouling coating materials, particularly to an epoxy grafted acrylate self-layering connecting paint and a preparation method thereof, wherein the epoxy grafted acrylate self-layering connecting paint comprises the following raw materials by mass: a bisphenol A type epoxy resin, an acrylate resin, an epoxy grafted acrylate resin, a thixotropic agent, a modifier, a pigment, a filler, a solvent and a curing agent. According to the invention, the epoxy grafted acrylate self-stratifying paint has excellent physical properties, can be matched withacrylate antifouling paints, obviously improves the connection performance, and can prolong the service life of the matched coating; and the connecting paint is low in preparation cost and wide in application range, and has high economic benefits.

Description

technical field [0001] The invention relates to the technical field of antifouling coatings, in particular to an epoxy grafted acrylate self-layering tie paint and a preparation method thereof. Background technique [0002] In order to ensure that the parts below the waterline of the hull shell are free from seawater corrosion and marine organisms, it is necessary to coat the hull with antirust paint and antifouling paint. However, due to the difference in raw materials and coating time between antirust and antifouling paints, antifouling paints cannot be directly coated on the antirust coating. Even if they can be coated, there are defects in adhesion performance. The general solution to the adhesion of the coating is to introduce a transition layer between the two coatings, that is, the connecting paint or the intermediate sealing paint. [0003] Since antifouling coatings are generally based on acrylic acid or acrylic modified resin, the connecting paint generally choose...
