Abstract

The invention discloses environmentally-friendly water/oil-repellent fluorinated acrylate emulsion and a preparation method thereof. The fluorinated acrylate emulsion is mainly prepared from 3-chloro-2-hydroxy propyl methyl acrylate, a fluorine-containing alkyl acrylate monomer, an acrylate monomer, a crosslinking monomer, a non-ionic emulsifier, a cationic emulsifier, a modifier, an initiator and deionized water. The fluorinated acrylate emulsion prepared by using the method can be applied to a textile finishing agent; and the textile finished by the emulsion has excellent water and oil repellency and anti-pollution characteristic.

Description

technical field [0001] The invention belongs to the field of fine chemicals, and in particular relates to a preparation method of a fluorine-containing acrylate copolymer emulsion for imparting water and oil repellency to fabrics and its application in industrial production. Background technique [0002] At present, with the development of domestic and foreign textiles and the improvement of people's living standards, functional finishing textiles have been widely used in domestic and foreign markets. Among them, functional textiles that are water-repellent, oil-repellent and easy to decontaminate are in constant demand in the international market. The world's largest clothing retailer GAP, the world's largest retailer Wal-Mart, the US retail giant Target, the European retail giant H&M, the world's famous clothing manufacturer Benetton, etc., have considerable sales in my country every year. The number of such products demanded. Therefore, people are more and more demanding f...
