Abstract

The invention discloses acrylic resin for high-water-resistance glass paint and a preparation method of the acrylic resin. The acrylic resin comprises the following components in parts by weight: 3-7 parts of fluorocarbon resin, 8-12 parts of isobornyl methacrylate, 4-8 parts of lauryl acrylate, 15-20 parts of styrene, 3-6 parts of hydroxyethyl methylacrylate, 5-8 parts of methacrylic acid, 8-15 parts of butyl methacrylate, 1-2 parts of an initiator, 25-30 parts of butyl acetate and 10-15 parts of a diluent. The preparation method comprises the following steps: (1) under the protection of nitrogen, adding butyl acetate into a reaction kettle and conducting heating; (2) mixing and dissolving isobornyl methacrylate, lauryl acrylate, styrene, hydroxyethyl methylacrylate, fluorocarbon resin, butyl methacrylate, methacrylic acid and part of the initiator to obtain a mixed solution; and (3) dropwise adding the mixed solution into a reaction kettle for reaction, adding the rest part of initiator for continuous reaction after the reaction, then conducting cooling, and finally adding the diluent to obtain the acrylic resin for the high-water-resistance glass paint.

Description

technical field [0001] The invention relates to the technical field of chemical materials, in particular to an acrylic resin for high water resistance glass paint and a preparation method thereof. Background technique [0002] Acrylic resin is a very important type of coating resin. Its synthesis process is highly controllable, and it has excellent weather resistance and pigment dispersibility, and its proportion in coating resin is increasing. With the improvement of people's living standards, the application of glass products is becoming more and more extensive, so the requirements for water boiling resistance, alcohol resistance and adhesion of glass paint are also higher. However, most glass paints on the market generally have defects such as water boiling resistance, poor alcohol resistance and low adhesion. Contents of the invention [0003] The purpose of the present invention is based on the poor water resistance of existing acrylic resins, and proposes a kind of ...
