F-Si acrylate copolymer and use method thereof as paint sealant

Abstract

The invention discloses an F-Si acrylate copolymer and a use method thereof as a vehicle paint sealant. The copolymer is a free radical polymerization reaction product by initiating the following components in percentage by weight with an initiator under the existence of an emulsifier: 35-55 percent of hard monomer, 20-50 percent of soft monomer, 0.5-5 percent of functional group monomer, 5-15 percent of fluorinated monomer, 3-16 percent of silicone monomer and 2-5 percent of nano material, wherein water is 100-150 percent of the total mount of the monomers, the initiator is 0.4-3 parts, and the emulsifier is 1.2-2 percent. The invention is applied to a vehicle paint face so that the vehicle paint face has the advantages of resisting water, oil, ultraviolet rays, static electricity, stain, washing, and the like and has the excellent self-cleaning function.

Description

Technical field [0001] The invention relates to the field of polymer synthesis. More specifically, it relates to a fluorine-silicon acrylate copolymer and its use method as a car paint surface sealant (also known as car glaze). After the car glaze is applied to the car paint surface, it can make the car paint surface have the advantages of water and oil repellent, anti-ultraviolet, anti-static, stain resistance, washing resistance, etc., and has excellent self-cleaning function. Background technique [0002] With the development of the economy, more and more cars have entered the lives of ordinary people. People are no longer satisfied with the excellent performance of the car, and pay more attention to the appearance of the car and pay attention to the care of the paint. Waxing is the most common way of car paint maintenance, of which carnauba wax is the car wax that many people respect. It can create a rich, warm luster and exude a lovely light fragrance. Car wax composed o...

Problems solved by technology

US4284668 describes that fluorine-modified polymers can improve the heat-resistant and cold-resistant temperature of the car surface sealant, but the formed film is relatively soft, easily scratched and damaged, and a hard protective film needs to be coated on the outer layer of the film; the fluorine-containing film described in US7173778 The film has low surface energy, but it is mainly used in optical instruments to prevent mirror pollution; US7407710 describes that the fluorosilicon modified copolymer can reduce the surface energy of the coating film, and has the advantages of water resistance, wear resistance and anti-staining. Compared with other materials, the protective durability of the coating film has been improved, but it is still unsatisfactory
