Solvent-based fluorocarbon resin

Abstract

The invention provides a solvent-based fluorocarbon resin, belonging to the synthesis process of the fluorocarbon resin. The fluorocarbon resin comprises the following components by mass percent: 38.56% of a chlorotrifluoroethylene monomer, 10.44% of methyl isobutyl ketone, 24.38% of dimethylbenzene, 0.832% of azodiisobutyronitrile, 1.024% of undecylenic acid, 2.894% of allyl alcohol and 21.87% of vinyl acetate, wherein, CTFE is the abbreviation for the chlorotrifluoroethylene monomer, and MIBK is the abbreviation for methyl isobutyl ketone. The synthesis process comprises the following steps: preparing, adding raw materials to a polymerization kettle, vacuumizing the polymerization kettle, adding the trifluorochloroethylene chlorotrifluoroethylene monomer raw material to the polymerization kettle, stirring and heating, and finally discharging the fluorocarbon resin. The fluorocarbon resin has durability, weatherability and chemical resistance, and shows special surface properties such as remarkable non-stick property, low surface tension, low friction property, water repellency, oil repellency and the like; and various coatings prepared by the fluorocarbon resin have outstanding high adhesive force and outstanding environmental aging resistance.

Description

technical field [0001] The invention relates to a synthesis process of fluorocarbon resin, in particular to a solvent-type fluorocarbon resin. Background technique [0002] Chinese patent "ultra-low surface energy type fluorocarbon resin", the patent number is 03112337.6, discloses a low surface energy type fluorocarbon resin, which is to introduce organosilicone ester during the polymerization of fluorocarbon resin, so that the fluorocarbon resin can It has a lower surface tension when forming a film, which further improves the self-cleaning property of the paint film. The method and formula of this patent mainly solve the surface tension of fluorocarbon resin in application and improve the self-cleaning property. [0003] At present, people still produce fluorocarbon resin through traditional synthesis process polymerization. The traditional synthesis process has a long production cycle and generally takes 72 hours to complete; after the polymerization reaction, the produc...
