Problems solved by technology

Its stability, gloss, hardness and adhesion are better than alkyd resins, but its weather resistance and corrosion resistance are not as good
Someone has made a polyaniline anti-corrosion paint with the bottom and surface integrated, and the general performance is still limited by the inherent performance of the polyester resin.
[0008] Polyaniline anticorrosive paint prepared with acrylic resin is mostly based on thermosetting hydroxyl resin, which has higher solid content than thermoplastic resin, has hydroxyl polar groups, good adhesion and good gloss, but relatively small molecular weight, which reduces its performance and is easy to construct. Shrinkage and shrinkage are produced, and its weather resistance is also very limited, which affects the function of polyaniline as a long-term anticorrosive paint

Abstract

The invention relates to back plane unity new type fluorine carbon lacquer enamel used in corrosion protection. Its component mass shares are as follows: fluoro resin 20-70, polyaniline 1-25, dispersant 0.1-5, and wetting agent 0.1-5. The invention can ensure coating anti-corrosive property, stability, brilliancy, doesn't add other conducting filling while making static conducting anti corrosive paint, will not cause the organic carbon black or graphite granule pollution for the medium to keep conducting resistance stable.

Description

technical field [0001] The invention relates to the field of paints, in particular to a novel fluorocarbon enamel with integrated bottom and surface for anti-corrosion and a preparation method thereof. Background technique [0002] According to statistics released by the world, the annual economic loss due to corrosion accounts for more than 4% of the world's total GDP, exceeding the sum of losses caused by fire, wind disasters and earthquakes. According to the data, the loss caused by corrosion in the United States accounts for about 4.2% of GDP, and the loss caused by corrosion in my country accounts for about 4% of GDP, which is about hundreds of billions of yuan. Especially steel corrosion loss is one of the biggest wastes in the world. Therefore, the problem of anti-corrosion has attracted people's great attention day by day. Anti-corrosion is a never-ending research topic. Anti-corrosion coatings based on metal surface shielding have been developed. Later, it was foun...
