A kind of cold coating silver topcoat containing modified acrylic acid polymer resin A and preparation method thereof

Abstract

The invention discloses a cold-coated silver topcoat containing modified acrylic polymer resin A and a preparation method thereof, belonging to the technical fields of chemical industry and paint. The components of the cold-coated silver topcoat include modified acrylic polymer resin A, dispersed agent, aluminum pigment, alignment aid, anti-settling agent, stabilizer, defoamer, leveling agent, mixed solvent, using self-developed modified acrylic polymer resin A as the preparation component, in the cold coating silver topcoat When used in the middle, it can play a very good role in fixing the silver paste, so that the silver powder can be fixed evenly, which improves the stability and durability of the product, and at the same time satisfies the product's fullness, chemical resistance, and has good weather resistance and mechanical properties, and the cold coating silver topcoat provided by the present invention has a simple construction and application process, can be sprayed by air, and can also be sprayed by high-pressure airless spraying. In terms of construction applicability, it is simple and convenient, has broad market prospects, and has great potential High economic and social benefits.

Description

technical field [0001] The invention belongs to the technical fields of chemical industry and paint, and in particular relates to a cold-applied silver topcoat containing modified acrylic polymer resin A and a preparation method thereof. Background technique [0002] Acrylic resin is the general term for acrylic acid, methacrylic acid and its derivative polymers. Acrylic resin coatings are thermoplastic or thermosetting resin coatings made of acrylic resins obtained by copolymerizing acrylate and styrene with other acrylates, or acrylic radiation. coating. [0003] In recent years, due to the continuous development and new construction of large-scale key projects in our country, especially the rapid development of the electric power industry, a large number of steel structure facilities have been widely used in construction. Because the steel structure is often corroded by external factors such as the atmosphere and chemical substances, corrosion usually occurs after severa...

Problems solved by technology

[0004] Cold-applied silver paint can be used as the top coat of galvanized parts, or it can be used as an overcoat with cold-applied galvanized paint, so that the coated layer can achieve the same anti-corrosion effect as hot-dip galvanized, and the appearance is similar to that of hot-dip galvanized layer. The appearance is similar, but the construction process of general hot-dip galvanized coatings is complicated, and it is necessary to control the temperature of the zinc bath, the immersion time, and the speed at which the workpiece is removed from the zinc bath. The coating process is complicated, and any one of the coatings Problems in the steps can have a great impact on the effect of the coating, and zinc dust, zinc slag, etc. are produced during the hot-dip galvanizing process, which not only seriously affects the quality of the galvanized layer, but also causes rough coating and heart tumors. It is not easy to deal with, and the other is easy to cause a lot of waste
