Abstract

The invention relates to antifouling, antistatic and water-based graphene-silicon-modified fluoroacrylic resin paint. The paint is prepared from, by weight, 50.0-70.0 parts of graphene-silicon-modified fluoroacrylic resin, 3.0-6.0 parts of dipropylene glycol butyl ether, 5.0-25.0 parts of pigments and fillers, 4.0-10.0 parts of an auxiliary agent and 10.0-20.0 parts of deionized water, wherein thegraphene-silicon-modified fluoroacrylic resin is prepared by a reaction of a hard acrylate monomer, a soft acrylate monomer, a fluoroolefin monomer, dimethylolpropionic acid, polytetrahydrofuran ether diol, hydroxypropyl-terminated polydimethylsiloxane, secondary distilled water, polyisocyanate, graphene, hydroxyethyl acrylate, anhydrous methanol and a neutralizing agent. The antifouling, antistatic and water-based graphene-silicon-modified fluoroacrylic resin paint prepared by the method has the advantages of high hardness, good antistatic property, high crosslinking density, great corrosionresistance, low surface tension, excellent antifouling capability, superior acid and alkali resistance and the like. The paint can be used as wood paint, metal paint, marine paint and the like.

Description

technical field [0001] The present invention relates to the preparation of a graphene and silicon modified fluoroacrylic resin, in particular to a graphene and silicon modified fluoroacrylic resin antifouling and antistatic water-based coating and its preparation method, which can be used for cement concrete, metal, wood and other various surfaces, which belong to the technical field of synthetic resin and water-based paint. Background technique [0002] Coating is a viscous liquid polymer synthetic material with no fixed shape at room temperature. After coating, it can form a tough coating film on the surface of the base layer through the volatilization of solvent or water evaporation or reaction curing. Coatings can not only play an aesthetic role, but also effectively protect the substrate. However, once the general coating encounters oil stains, it is difficult to clean. Forcible cleaning will damage the film surface, so that the coating needs to be repainted. [0003] ...
