Plastic protective coating capable of being underwater used and preparation method thereof

Abstract

The invention discloses a plastic protective coating capable of being underwater used and a preparation method thereof. The plastic protective coating comprises the following components in parts by weight: 10-20 parts of butyl acrylate, 2-7 parts of stearic acid, 1-5 parts of talcum powder, 0.8-2 parts of an anti-aging agent, 0.2-0.6 part of an anti-foaming agent, 2-5 parts of ethylene carbonate, 5-10 parts of 2-ethyl cyanoacrylate, 3-8 parts of acrylyl oxyethyl dimethyl ammonium chloride, 1-4 parts of disodium succinate, 0.8-2 parts of carboxymethyl cellulose, 8-15 parts of maleic anhydride and 10-20 parts of ethyl acetate. The preparation method comprises the following steps of: stirring and mixing butyl acrylate, stearic acid, ethylene carbonate, 2-ethyl cyanoacrylate, crylyl oxyethyl dimethyl ammonium chloride, disodium succinate, carboxymethyl cellulose, ethyl acetate and maleic anhydride; then increasing temperature and stirring in a reaction kettle for reaction; then reducing the temperature, adding talcum powder, the anti-aging agent and the anti-foaming agent, uniformly mixing, and grinding in a grinding machine to obtain the plastic protective coating.

Description

technical field [0001] The invention belongs to the technical field of chemical paint preparation, in particular to a plastic protective paint that can be used underwater and a preparation method thereof. Background technique [0002] Paint is a chemical mixture coating that can firmly cover the surface of objects for protection, decoration, marking and other special purposes. The relatively authoritative book "Painting Technology" in the Chinese coatings industry defines it as follows: "Painting is a material that can be coated on the surface of an object by different construction techniques to form a firm adhesion, a certain strength, and a continuous coating. Solid film. The film formed in this way is commonly called coating film, also known as paint film or coating.” It belongs to organic chemical polymer materials, and the formed coating film belongs to the type of polymer compound. According to the classification of modern chemical products, coatings belong to fine ch...

Problems solved by technology

The coatings used for plastic coating in the early days were all solvent-based coatings, such as containing xylene, propylene glycol, ethylene glycol, etc. At present, there are many types of coatings used for plastics, which can be applied to various plastic parts, but they are currently suitable for water The plastic coating used underwater has not been reported. For the plastic parts used in the underwater environment, due to the particularity of the underwater environment, the service life of the plastic will be shortened. The Chinese patent application number 200510017646.1 discloses a A water-based coating for plastics, the purpose of which is to solve the problem of polluting the environment and damaging the health of operators due to the volatilization of solvents during the use of solvent-based plastic coatings; the Chinese patent application number 200310111132.3 discloses a water-based coating for plastic coating And preparation method, coating is made up of water dispersion resin, water-based pigment slurry, water-based filler slurry, film-forming aid, water-based paint auxiliary agent and water, can be used for the coating of various plastic surfaces; But the plastic coating disclosed above can not Applied to the underwater environment, it cannot protect the plastic workpieces used underwater
