Abstract

The invention discloses a fluorocarbon coating and a method for preparing colored aluminum profiles from the fluorocarbon coating, belonging to the field of chemical engineering coatings. The fluorocarbon coating comprises the following components in percentage by weight: 30wt%-70wt% of fluorinated acrylate oligomers, 0-50wt% of acrylate oligomers, 10wt%-40wt% of reactive acrylate monomers, 5wt%-10wt% of a photoinitiator, 5wt%-10wt% of a curing agent, 5wt%-30wt% of pigments, 0-7wt% of fillers and 0-3wt% of an aid. According to the fluorocarbon coating, dual curing including ultraviolet light curing and spontaneous curing can be realized; the inner wall or dead corners, which cannot be irradiated by ultraviolet light, of the profiles can be spontaneously cured within 24 hours, so that the problem that the surface of the UV ultraviolet light fluorocarbon coating cannot be irradiated by the ultraviolet light is solved; after the coating is cured, a paint film has rich colors and excellent weather resistance and can meet outdoor use requirements.

Description

technical field [0001] The invention belongs to the field of chemical industry, and relates to a fluorocarbon coating, in particular to a colored fluorocarbon coating for double-cured profiles of ultraviolet light curing and natural curing. Background technique [0002] With the development of the economy, aluminum profiles are widely used in architectural decoration, household appliances, transportation, aerospace and other fields. At present, the surface treatment of aluminum profiles is mainly through the electroplating process to produce aluminum profile products in various shapes and colors. Liquids such as nickel sulfate, nickel chloride, boric acid, etc. have the disadvantages of high risk and large pollution, and the electroplating process of aluminum profiles is difficult to control, and the surface electroplating layer is prone to oxidation and blackening after a long time, which greatly limits the use of this process. [0003] The use of colored fluorocarbon coati...
