Embodiment 1

[0020] Present embodiment proposes a kind of waterborne acrylic resin antistatic coating, and described coating comprises following component by weight percentage:

[0021]

[0022] The modified acrylic resin is formed by reacting methacrylic acid, ethyl acrylate, butyl acrylate, n-butanol and modified substances under the action of an initiator. The modified substance is organosilicon and epoxy resin, the organosilicon is acryltrimethoxysilane, and the epoxy resin can be selected from E-51, E-44, E-20 and E-12. The initiator is azobisisobutyronitrile or benzoyl peroxide. In the present invention, the modified acrylic resin adopts a free radical polymerization mechanism. First, the α-H atom on the ortho-carbon of the acid bond in the epoxy resin and the H atom on the tertiary carbon atom are relatively active. Under the action, free radicals are formed, and monomer free radicals are also present at the same time; organosilicon monomers containing double bonds and acrylic a...

Abstract

The invention discloses an aqueous acrylic resin antistatic paint and a preparation method thereof. The paint comprises the following components by weight percentage: 40 to 60 parts of modified acrylic resin, 5 to 15 parts of graphene, 10 to 20 parts of polyurethane, 10 to 30 parts of deionized water, 3 to 5 parts of a thickener, 3 to 5 parts of a dispersant, and 3 to 5 parts of a defoamer. Through organosilicon and epoxy resin modified acrylic resin, the solvent resistance, high and low temperature resistance, and oxidative aging resistance of acrylic resin can be greatly improved, the raw material matrix for preparing the antistatic paint is excellent and stable, after mixing with the graphene to prepare the paint, no agglomeration occurs, the stability is higher, the electrical conductivity is better, and the excellent characteristics of the polymer are maintained, the paint also has the conductive properties of graphene, has good anti-oxidation aging performance, and has the advantages of high efficiency, energy saving, environmental protection and no pollution.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based acrylic resin antistatic coating and a preparation method thereof. Background technique [0002] In daily life, many materials are prone to static electricity accumulation during use, resulting in vacuuming, electric shocks, etc. leading to vicious accidents, such as static electricity can cause production obstacles, explosions, and fires. In order to eliminate the harm caused by static electricity, the preparation of antistatic coatings has become a research hotspot, and antistatic coatings are becoming more and more popular in daily life. How to reduce resistivity and improve thermal-oxidative aging performance is an important research content in this field, but the theory of modifying conductive fillers and polymers is relatively immature, and the research results are not satisfactory. Contents of the invention [0003] For the technical problems existing in the prior ...
