Abstract

The invention discloses a super-weather-resistant acrylic anodic electrophoretic coating. The components of the super-weather-resistant acrylic anodic electrophoretic coating and the weight percentages of each component are: isopropanol 5-9%, butyl cellosolve 15-35%, ( Meth)acrylic acid 5‑15%, n-butyl (meth)acrylate 20‑40%, methyl methacrylate 18‑40%, styrene propylene 3‑9%, (meth)acrylate β‑hydroxyethyl 12 ‑23%, (meth)isooctyl acrylate 10‑25%, azobisisobutyronitrile AIBN 0.5‑2.5%, acrylic fluoromonomer 10‑30%; the sum of the above components is 100% . The super-weather-resistant acrylic acrylic anodic electrophoretic coating adopting the technical solution of the invention has long natural weather resistance, good stain resistance, water resistance, and chemical resistance are also greatly improved.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an acrylic anode electrophoretic coating and a production method thereof. Background technique [0002] Acrylic anodic electrophoretic coating is more and more commonly used in today's society. Compared with spray coating, it is low pollution, energy-saving, resource-saving, protective and anti-corrosion coating, with smooth coating film, good water resistance and chemical resistance Features. However, ordinary acrylic anodic electrophoretic coatings need to be baked at high temperatures for a long time, which consumes energy and has high requirements for the high temperature resistance of the substrate. [0003] At present, ordinary anodic electrophoretic coatings on the market have a short resistance to natural weather. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a super-weather-resistant acrylic anodic electrophoretic...
