Problems solved by technology

Moreover, fluorine atoms can reduce the surface free energy and surface tension of the film, thereby showing good water-repellent, oil-repellent and anti-fouling surface properties, but organic fluorine materials have poor low temperature resistance
[0003] Silicone materials have the properties of both inorganic and organic substances, and have excellent high and low temperature resistance (-60 ~ 310 ° C), UV resistance, oxidation resistance and other properties, but silicone materials have poor resistance to chemical media

Abstract

The invention relates to an organofluorine modified polysiloxane acrylate copolymer emulsion finishing agent which is mainly prepared from the following reaction components in parts by weight: 3-25 parts of fluorine-containing monomers, 0.8-2 parts of an organosilicone monomer, 12-18 parts of acrylic monomers, 0.80-2 parts of an emulsifier, 0.1-0.3 part of a NaHCO3 buffer agent, 0.1-0.3 part of aninitiator and 50-80 parts of deionized water. The organofluorine modified polysiloxane acrylate copolymer emulsion prepared in the invention has high reactive conversion rate, high emulsion stabilityand small emulsion particle size, the reaction solidification rate is low, and the latex film has excellent water and oil repellent properties.

Description

technical field [0001] The invention relates to the technical field of textile finishing agents, in particular to an organofluorine-modified polysiloxane acrylate copolymer emulsion finishing agent and a preparation method thereof. Background technique [0002] Fluorine-containing materials are generally long-chain fluorocarbons. The bond energy of the carbon-fluorine bond is relatively large and relatively stable. The fluorine atoms are not only firmly bonded to the carbon atoms, but also arranged very closely on the outer layer of the carbon skeleton, effectively preventing the carbon atoms and carbon Chain exposure, so fluorocarbons exhibit excellent chemical stability, weather resistance, corrosion resistance, oxidation resistance and other properties. Moreover, fluorine atoms can reduce the surface free energy and surface tension of the film, thereby showing good water-repellent, oil-repellent and anti-fouling surface properties, but organic fluorine materials have poor...
