Abstract

The invention relates to the preparation of silicon fluorine / or oil modified acrylate copolymer cationic emulsion. The emulsion is obtained through the emulsion polymerization in the presence of a cationic surfactant and a nonionic surfactant. The emulsion comprises an acrylic acid alkyl ester and (methyl) acrylic acid alkyl ester, ethylene carbonate, aroma substituted olefin and functional monomers such as N-hydroxyalkyl acrylamide, (methyl) acrylic acid alkyl fluoride ester, ethynyl / acryloyl oxygen ethyl trialkoxy silane or polymerisable acryloyl oxygen alkyl urethane oil, (methyl) acryloyl oxygen ethyl trialkyl ammonium chloride and / or (methyl) acrylic acid dimethylamine group ethyl ester and a crosslinking agent. The cationic emulsion has excellent performance and can be widely applied to paper products, plastics, coating agents for leather and top grade coatings.

Description

Technical field: [0001] The present invention relates to an acrylate copolymer cation modified with functional monomers such as fluoroalkyl (meth)acrylate and vinyl trialkoxysilane / or polymerizable acryloxyalkyl urethane oil Preparation of emulsion. Background technique: [0002] Cationic acrylic emulsion is different from anionic emulsion. The polymer surface has a positive charge. It is not only beneficial to the neutralization, adsorption and adhesion of the negatively charged surface, but also has the functions of sterilization, dustproof and antistatic, so it is widely used. It is used in the treatment of fabrics, paper and leather, the antistatic treatment of polymer materials, and the inherent adhesion, weather resistance and film-forming properties of acrylic resins, so acrylic cationic emulsions can also be used in architectural coatings. [0003] There are many introductions about fluorosilicone modified acrylic anionic emulsion, but there are few cationic emulsions. At...
