Problems solved by technology

However, this fluorocarbon coil coating has the following defects: (1) During the curing process, PVDF resin and other resins have no crosslinking or chemical reaction, but simple physical melting, so this curing system cannot prepare normal temperature drying fluorocarbon Coatings cannot be applied to local repairs or on-site auxiliary parts that require normal temperature drying fluoroc

Abstract

The invention relates to a kind of fluo-carbo dope and the preparation method. It is mainly made up of fluororesin, bridging agent, dye, filling, compounding and component solvent. The weight ratio as follow, fluororesin : bridging agent : dye : filling : compounding : component solvent equal to 1:0.10-0.30:0-0.35:0-0.05:0.01-0.05:0.10-0.40. The mentioned fluororesin is composed by 3-fluororesin or 4-fluororesin or both. The book of words gives the preparation method. chemical reaction will take place when fluororesin gets along with bridging agent under the condition solidifying process of fluo-carbo dope. So, add no-close isocyanic ester, it can be executed into dry fluo-carbo dope as to be used to sectional repair in the roofing surface. The dope has low capability of the lacquer film surface, good dirt resistance, easy ablution and excellent mechanical property and excellent aging performance.

Description

technical field [0001] The invention relates to a fluorocarbon paint and a preparation method thereof, belonging to the paint industry. Background technique [0002] The development and utilization of coil coatings in my country started in the 1980s. Due to the characteristics of coil coatings in terms of quality and coating, they are widely used in construction, automobile manufacturing, home appliances and packaging. According to different film-forming substances, coil coatings can be divided into six categories: polyester, polyurethane, acrylic acid, epoxy, PVC plastisol and fluorine-containing coatings. Among them, fluorine-containing coil coatings have excellent weather resistance, solvent resistance, chemical resistance, abrasion resistance, stain resistance and easy processing, and the outdoor service life can reach 15 to 20 years, so the Coil-like coatings are favored by the majority of users. These products are mainly used in places requiring high weather resistan...
