Problems solved by technology

[0004] However, due to the small particle size and large specific surface energy of nano oxides, it is very easy to agglomerate or be embedded by pigments or fillers during the coating preparation process and cannot be uniformly dispersed in the coating.
In addition, during the coating process, pigments or fillers will also cover the surface of nano-oxides or their modified particles, which will affect the performance of the coating and lead to poor overall performance of the coating.

Abstract

The invention discloses a high-performance protective paint and a preparation method thereof. It is prepared according to the following components by weight: 70-80 parts by weight of fluorocarbon resin, 15-22 parts by weight of acrylic resin, 5-10 parts by weight of aldehyde and ketone resin, 2-5 parts by weight of activated carbon, and 4 parts by weight of nano-dioxide Silicon, 0.1 parts by weight graphene, 0.1 parts by weight defoamer. 10-100 parts by weight of alcohol-containing aqueous solution. The prepared high-performance protective coating has excellent corrosion resistance and air purification function, and can be applied to metal surface coating on the surface or inner wall of petroleum, chemical equipment, military equipment, self-propelled and towed vehicles, and other substrates.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-performance protective coating and a preparation method thereof. Background technique [0002] Fluorocarbon resin is a kind of polymer resin containing fluorine atoms in its molecular structure. It has excellent high and low temperature resistance, dielectric properties, electrical insulation, chemical stability, weather resistance, non-combustibility, non-stickiness and low friction coefficient. And other characteristics, it is widely used in construction, chemical industry, electrical and electronic industry, machinery industry, aerospace industry, and has a huge development prospect. [0003] Fluorocarbon resin coatings improve the performance of coatings by adding additives to the resin matrix. CN200810195134.8 discloses a self-assembled composite nano-oxide anti-corrosion coating cured at room temperature. The nanoparticles are modified by a fluorocarbon silane coup...
