Abstract

The invention discloses a use method of a fluorocarbon spraying coating additive. The use method comprises the following steps: S1, preparing the fluorocarbon spraying coating additive, wherein the additive comprises the following components in percentage by mass: 28-42% of low-density polyethylene, 10-18% of glutaric anhydride, 6-12% of chlorinated polyethylene, 30-45% of hydrophobic filler and 4-8% of a silver ion antibacterial agent; s2, pretreatment is conducted, specifically, the aluminum profile is pretreated, so that a passive film is formed on the surface of the aluminum profile; s3, spraying a fluorocarbon primer; s4, spraying a fluorocarbon finish paint: adding a fluorocarbon spraying paint additive into a fluorocarbon finish paint formula, and performing electrostatic spraying on the fluorocarbon finish paint to form a fluorocarbon finish paint layer; s5, spraying fluorocarbon varnish; and S6, curing and baking. The problems that products produced through an existing fluorocarbon spraying technology are unstable in quality and have chromatic aberration are solved.

Description

technical field [0001] The invention relates to a method for using a fluorocarbon spray coating additive. Background technique [0002] Aluminum profiles have the characteristics of low density, light weight, strong processability and plasticity, and are widely used in the field of construction and home furnishing. In order to improve the corrosion resistance and aging resistance of aluminum profiles and improve the surface decoration effect of aluminum profiles, surface treatment is usually required. The surface treatment technology of aluminum profiles mainly includes: powder spraying, fluorocarbon spraying, electrophoresis, anodizing and wood grain transfer treatment. [0003] Due to the fluorine-carbon bond structure with short bond length and bond energy much higher than carbon-carbon and carbon-oxygen bond energy, fluororesin can be closely arranged around the polymer, so that the fluorocarbon powder coating exhibits excellent performance. Weather resistance, widely ...
