Abstract

The invention discloses a hydrophobic anti-fouling ultraviolet curing coating and a preparation method thereof. The coating is prepared from the following raw materials in parts by weight: 40 to 50 parts of graphene modified bisphenol A type epoxy acrylic resin, 20 to 30 parts of a reactive diluent, 20 to 25 parts of a solvent, 5 to 10 parts of a photoinitiator, 1 to 5 parts of a leveling agent, and 0.1 to 1 part of functional acrylic resin containing double bonds. The preparation method comprises the steps: adding the components into a reaction container in parts by weight, and stirring and dispersing at a high speed for 3.5-5.5 hours. According to the invention, the problems of toughness strength, wear resistance and self-repairing of a common anti-fouling coating layer are solved.

Description

technical field [0001] The invention relates to the field of ultraviolet curing coatings, in particular to hydrophobic and antifouling ultraviolet curing coatings and a preparation method thereof. Background technique [0002] Traditional coating curing usually removes the solvent in the polymer solution by heating, that is, physical drying, to obtain a hardened paint film. UV curing is to use the energy of ultraviolet light to initiate the polymerization and crosslinking reaction between the low molecular prepolymer or oligomer in the coating and the monomer molecule as a reactive diluent to obtain a hardened paint film. The essence is to form a chemical bond. Achieve chemical drying. [0003] Curing coatings are also called photosensitive coatings, and those that use ultraviolet light as the energy source for coating curing are called UV-curing coatings. Ultraviolet (UV) curing coatings do not require heating and can quickly cure into films on flammable substrates such a...
