Problems solved by technology

[0003] Compared with polyurethane coatings, although fluorocarbon coatings have excellent properties of corrosion resistance, weather resistance, and stain resistance, the elongation at break of the paint film or coating formed by the fluorocarbon coatings disclosed in the prior art is low, and its tensile properties cannot be compared with High ductility matches the substrate, and the diluent of the solvent-based fluorocarbon coating will swell the plastic substrate (such as PVC film, TPU film), resulting in poor adhesion between the paint and the plastic substrate

Abstract

The invention provides a fluorocarbon coating. The fluorocarbon coating comprises the following raw materials in parts by weight: 5-70 parts of fluorocarbon resin; 0.1-30 parts of an acrylic monomer and / or an acrylic monomer prepolymer; 0.1 to 40 parts of an auxiliary agent; 0.2 to 35 parts of a curing agent; and 20-80 parts of a diluent. The fluorocarbon resin is subjected to graft modification through the acrylic monomer and / or the acrylic monomer prepolymer, so that the elongation at break of a paint film or a coating formed by the fluorocarbon coating is improved, and the tensile property of the fluorocarbon coating is matched with that of a high-ductility base material. And meanwhile, during coating, a diluent with poor swelling property on the flexible plastic base material can be used for dilution, so that the swelling of the fluorocarbon coating on the flexible plastic base material during coating is greatly reduced. According to the coating prepared by the invention, the adhesive force between the fluorocarbon coating and a plastic base material (such as a PVC (Polyvinyl Chloride) film and a TPU (Thermoplastic Polyurethane) film) is obviously improved, and the interlayer binding force between the modified fluorocarbon coating and the base material is ensured.

Description

technical field [0001] The invention relates to the technical field of coatings, and in particular provides a fluorocarbon coating, a preparation method thereof and a multi-layer film. Background technique [0002] Fluorocarbon coatings are coatings with fluorocarbon resin as the main film-forming material, which are used in transportation tools, construction, electronic products, mining-related facilities, chemical processing industries, wastewater treatment facilities and other fields. At present, typical solvent-based fluorocarbon coatings are mainly FEVE type, that is, fluoroolefin monomers (chlorotrifluoroethylene or tetrafluoroethylene) and vinyl monomers (vinyl ether monomers or vinyl ester monomers or their mixed monomers) ) formed copolymers. [0003] Compared with polyurethane coatings, although fluorocarbon coatings have excellent characteristics of corrosion resistance, weather resistance and pollution resistance, the elongation at break of the paint film or coa...
