Coating classification: fluororesin coating

Core tip: the coating made of fluoropolymer resin is called fluororesin coating The durability and weatherability of this kind of coating are the best among all architectural coatings at present, so it is called super weatherability architectural coating In recent years, the super weather resistant building coatings have developed rapidly They can be made into water dispersive coatings, solvent dispersive coatings or solvent based coatings Base material The fluorocarbon resin coating material is mainly polyvinylidene fluoride (PVDF) resin, which is made from partial two fluoroethylene, and is prepared by emulsion polymerization or suspension polymerization Vinylidene fluoride under the action of free radical initiator Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Coating home news: the coating made of fluoropolymer resin as the base material is called fluororesin coating The durability and weatherability of this kind of coating are the best among all building coatings at present, so it is called super weatherability building coating In recent years, the super weather resistant building coatings have developed rapidly They can be made into water dispersive coatings, solvent dispersive coatings or solvent based coatings The base material of fluorocarbon resin coating is mainly polyvinylidene fluoride (PVDF) resin, which is made from partial two fluoroethylene and prepared by emulsion polymerization or suspension polymerization Under the action of free radical initiator, vinylidene fluoride is easy to polymerize into partially crystalline polymer, in which the fluorine content is 59.4% Besides the homopolymer of vinylidene fluoride, various copolymers of vinylidene fluoride can also be prepared Among many copolymers, hexafluoroethylene plays an important commercial role Among them, high-performance fluoroelastomer based on hexafluoropropene (HFP) - PVDF copolymer containing 15% - 40% mole fraction has been made In addition, the flexible copolymers of pvdf-tfe (tetrafluoroethylene) and the ternary copolymers of pvdf-tfe-hfe were also prepared In addition to polyvinylidene fluoride resin as the base material, acrylate resin is generally selected as the base material modifier Acrylic modifier is generally thermoplastic acrylic resin based on methacrylate Its main function is to improve the dispersion of pigment, the spread of paint on the substrate and the adhesion to the substrate Acrylic resin can also improve the relative stability of the final coating In the preparation of paint, the inertia of polyvinylidene fluoride can not only achieve good outdoor durability and chemical resistance, but also have adverse effects For example, the inertia of polyvinylidene fluoride makes it difficult to disperse the paint, further inhibits the interaction with the substrate, and is not conducive to good adhesion Therefore, acrylic acid modifier is used to improve the dispersion of the paint and improve the coating Material adhesion, and can bring unique performance to the final coating, such as high hardness or high gloss Auxiliary In order to ensure the storage stability, coating performance and coating performance of the coating, a variety of additives, including anti settling agent, defoamer and inhibitor, dispersant, emulsifier, preservative, bactericide, surface active agent, matting agent, drier, anti skinning agent, rheological modifier and UV absorber, should be selected in the formula of PVDF building coating as common coating 。 Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
