Problems solved by technology

The above-mentioned prior art and the water-based metallic paint formulated with water-based styrene-acrylic emulsion for common metals currently on the market either have a certain gloss and hardness, or have a certain anti-corrosion ability, but it is difficult to take into account the performance of the primer and the topcoat at the same time. At the same time, it takes a lot of manpower and material resources before two coats of spraying or brushing. Therefore, it is necessary to develop an anti-corrosion coating with good gloss and hardness, and excellent water resistance, salt water resistance and salt spray resistance. Dedicated water-based acrylic emulsions are urgently needed research work

Abstract

The invention discloses water-based styrene-acrylic emulsion for primer and topcoat integrated metallic paint and a preparation method of the water-based styrene-acrylic emulsion. The raw material of the water-based styrene-acrylic emulsion is composed of the following components of, by weight, 8-13 parts of styrene, 21-26 parts of butyl methacrylate, 2-7 parts of butyl acrylate, 1-5 parts of iso-octyl acrylate, 1-5 parts of acrylic acid, 1-3 parts of phosphate ester functional monomers, 1-3 parts of emulgators, 0.3-0.6 part of persulfate, 01-0.3 part of oxidizing agent, 0.10-0.3 part of reducing agent, and 53 parts of water. The phosphate ester functional monomers are grafted into acrylic based emulsion particles through polymerization reaction, so that the prepared metallic paint and metallic ions have good complexation, and a quite compact protective film is formed; meanwhile, a gloss controllable technology is adopted, and not only are the good water resistance, salt water resistance, salt fog resistance and other corrosion resistance ensured, but also the good glossiness and hardness are achieved. The paint is directly sprayed or brushed on the surface of metal after being prepared, a compact, flat and smooth paint film is formed, and the water-based styrene-acrylic emulsion for the metallic paint combined with the performance requirements of primer and topcoat is obtained.

Description

Technical field [0001] The invention relates to the technical field of polymer emulsions for metal anticorrosion, in particular to a water-based styrene-acrylic emulsion for metal paint with a bottom surface and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of the industrial industry, the increasingly demanding anti-corrosion requirements and the fierce competition in the market, especially the gloss, hardness, and anti-corrosion and anti-rust performance requirements of the metal surface paint film are getting higher and higher. It has the excellent anti-corrosion performance of the primer, but also satisfies the gloss and hardness requirements of the topcoat. Patent application CN102432743A discloses a polymer emulsion for water-based metal anticorrosive coatings and a preparation method thereof. The raw materials include 13.0-18.0% of dry oleic acid modified prepolymerized intermediates and 16.0-20.0% of acrylate monome...
