Abstract

The invention discloses an electrophoretic paint used for an aluminum profile, a preparation method thereof and the aluminum profile prepared through electrophoresis. The electrophoretic paint comprises the following raw materials: acrylic acid, methyl methacrylate, butyl acrylate, hydroxyethyl methylacrylate, glyceryl monomethacrylate, trimethylolpropane trimethacrylate, ethoxylated trimethylolpropane trimethacrylate and bisphenol ethoxide A dimethacrylate. The aluminum profile is treated through electrophoresis by using the electrophoretic paint provided in the invention, the two high energyconsumption working procedures of anodic oxidation and coloring can be omitted, and the aluminum profile is energy-saving, environmentally-friendly and stable in quality.

Description

technical field [0001] The invention relates to the technical field of surface treatment of aluminum profiles, in particular to an electrophoretic paint for aluminum profiles, a preparation method thereof and an aluminum profile prepared by electrophoresis. Background technique [0002] With the vigorous development of the national economy, at present, my country is a big country of aluminum consumption. Electrophoretic coating is to immerse the coated metal product in the electrophoretic coating after degreasing, cleaning, surface adjustment, phosphating, pure water cleaning and other pre-treatments. Uniform water-insoluble coating film, after the coating film is dried, has strong corrosion resistance, thereby prolonging the service life of the product. The preparation process of ordinary aluminum alloy profiles coated with electrophoretic paint generally includes the steps of pretreatment-anodizing-coloring-electrophoresis-curing, and as people's awareness of environmenta...
