Problems solved by technology

[0003] Water-based coatings use water as a solvent or dispersion medium. They are non-toxic, odorless, cheap, and rich in raw material resources, which can greatly reduce raw material costs and air pollution; and can greatly improve the storage, transportation and construction of coatings. Safety in the process and broad application prospects; but compared with oil-based paints, water-based paints have poorer corrosion resistance and anti-rust performance, especially in terms of water resistance and impermeability than oil-based paints

Abstract

The invention provides antirust and corrosion-resistant rosin phenolic resin paint. The antirust and corrosion-resistant rosin phenolic resin paint is prepared from the following components in parts by weight: 25 to 30 parts of rosin modified phenolic resin; 20 to 25 parts of n-decyl acrylate and / or n-decyl methacrylate; 10 to 20 parts of methyl acrylate and / or methyl methacrylate; 0.4-2 part of glycidyl methacrylate; 1-5 parts of epoxy resin; 6-12 parts of a styrene-acrylic emulsion; 1-4 parts of an anti-flash rust agent; 0.2-0.6 part of tetrazole; 5-15 parts of glass flakes; 8-12 parts of anticorrosive filler, wherein the anticorrosive filler is a nitrile guanidine modified alpha-zirconium phosphate nanosheet; according to the invention, the rosin modified phenolic resin is matched withthe acrylic resin, so that the coating integrates the excellent properties of the two resins, the gloss and color retention and weather resistance of the paint layer are improved, and the nitrile guanidine modified alpha-zirconium phosphate nanosheet is used as the anticorrosive filler, thereby enhancing the rust resistance and corrosion resistance of the coating.

Description

technical field [0001] The invention relates to the technical field of antirust and anticorrosion coatings and preparation thereof, in particular to an antirust and anticorrosion rosin phenolic resin paint and a preparation method thereof. Background technique [0002] Anti-rust and anti-corrosion coatings are an important part of the equipment manufacturing industry and an indispensable anti-corrosion protective layer for metal products, especially steel products. Traditional solvent-based antirust coatings mainly use organic solvents as the dispersion medium. Therefore, a large amount of organic compounds, namely Volatile Organic Composition (VOC for short), will volatilize in the process of preparation and use. The volatilization of VOC is a potential threat to the living environment and human health. Therefore, researchers gradually shift the focus of research from oil-based paints to water-based paints. [0003] Water-based coatings use water as a solvent or dispersi...
