Problems solved by technology

[0003] Tetrafluorocarbon coating, because its main component fluorocarbon resin contains four fluorocarbon bonds, the fluorocarbon bonds are difficult to break under conditions such as heat and light, so it has longer weather resistance and super strength than difluorocarbon and trifluorocarbon Excellent corrosion resistance to chemical media, the aluminum substrate prepared by it has excellent aging resistance and chemical resistance, but fluorocarbon coatings, especially the existing tetrafluorocarbon powder coatings, have adhesion after film formation in production Poor focus and insufficient hardness

Abstract

The invention relates to an aluminum single board, in particular to a carbon tetrafluoride aluminum single board. The carbon tetrafluoride aluminum single board comprises an aluminum base board layer, a chromizing film layer and a carbon tetrafluoride layer which are sequentially arranged from inside to outside. The carbon tetrafluoride aluminum single board is formed by electrostatically spraying carbon tetrafluoride powder coatings which are composed of the following components in part by weight: 30-60 parts of arcarbon tetrafluoride resin, 5-20 parts of acrylic resin, 1-5 parts of hydroxylalkyl acyl, 3-8 parts of tetramethoxy methyl glycoluril, 1-8 parts of zirconium oxide, 2-6 parts of calcium silicate, 2-5 parts of magnesium oxide, 1-3 parts of silicon-aluminum oxide, 1-25 parts of paint and 1-5 parts of accessory ingredient. The carbon tetrafluoride aluminum single board provided by the invention has excellent chemical resistance, weather resistance, adhesive force and gloss.

Description

technical field [0001] The invention relates to an aluminum veneer, in particular to a tetrafluorocarbon aluminum veneer. Background technique [0002] The aluminum veneer sprayed with fluorocarbon powder coating is light in weight and easy to install, and because the fluorocarbon powder coating is completely solvent-free, it can be completely converted into a coating film, and the coating efficiency is high, and the comprehensive performance of protection and decoration is excellent. Good, with excellent chemical resistance, heat resistance, weather resistance so that the fluorocarbon aluminum veneer has the advantages of non-toxic, anti-corrosion, anti-oxidation, beautiful, easy to clean, etc. It is widely used in the field of decorative materials and is favored all over the world. Extensive attention has been paid to it, which has achieved rapid development. [0003] Tetrafluorocarbon coating, because its main component fluorocarbon resin contains four fluorocarbon bonds...
