Abstract

The invention relates to a tetrafluoroethylene resin coating, which comprises a main agent and a curing agent, wherein the weight ratio of the main agent to the curing agent is 5-11:1; the main agent comprises the following components in percentage by weight: 50 to 60 percent of tetrafluoroethylene resin, 1 to 3 percent of film-forming auxiliary agent, 20 to 32 percent of pigment, and the balance of solvent; and the curing agent comprises the following components in percentage by weight: 50 to 60 percent of polyisocyanate, and the balance of solvent. Compared with the prior art, the tetrafluoroethylene resin coating is prepared by using isocyanate to cure hydroxyl-contained normal temperature crosslinking type tetrafluoroethylene fluorocarbon resin as the main film forming object compounded with other auxiliary agents, has the excellent characteristics of weatherability, corrosion resistance, chemical resistance, salt fog resistance, easy cleaning and the like, has a simple coating method and good drying property without dying by high-temperature baking, can performing coating on various base materials and under various environments, and has wide application range.

Description

technical field [0001] The invention relates to coatings, in particular to a tetrafluororesin coating. Background technique [0002] Fluorine resin coatings have the advantages of good durability and long maintenance time, and are widely used in occasions requiring high corrosion resistance. Among them, polytetrafluoroethylene resin has superior durability and is the most widely used of all fluororesins. However, traditional PTFE resins are insoluble in solvents, and require high-temperature baking and curing, and cannot be well integrated with other materials, so they are only limitedly used in some special purposes. Contents of the invention [0003] The purpose of the present invention is to provide a tetrafluororesin coating with simple coating method and good drying performance in order to overcome the above-mentioned defects in the prior art. [0004] The purpose of the present invention can be achieved through the following technical solutions: [0005] A tetrafl...
