Abstract

The invention discloses a silane modified antibacterial leather coating. The silane modified antibacterial leather coating comprises, by weight, 0.1-0.2 parts of urotropine, 0.1-0.2 parts of gamma-aminopropyltriethoxysilane, 0.7-1 part of carboxymethylcellulose sodium, 0.2-0.4 parts of butyltin mercaptide, 1.7-2 parts of polyvinylpyrrolidone, 0.8-1 part of polyacrylamide, 0.1-0.13 parts of triethanolamine, 190-200 parts of methyl methacrylate, 3-4 parts of sodium dodecyl sulfate, 0.2-0.3 parts of ammonium persulfate, 6-7 parts of a 20-25% formaldehyde solution, 16-20 parts of zinc acetate, 4-7 parts of silver nitrate, 1-2 parts of calcium hydrogen phosphate, 0.1-0.2 parts of polyglyceryl-10 oleate, 1-2 parts of hydroxystearic acid and 1.6-2 parts of stannous chloride. The coating has the advantages of good antibacterial property, excellent water vapor permeability and excellent waterproof property, and leather coated with obtained emulsion has good antibacterial property and excellent health performances.

Description

technical field [0001] The invention relates to the technical field of leather coatings, in particular to a silane-modified antibacterial leather coating and a preparation method thereof. Background technique [0002] Leather finishing agent / textile coating agent is a polymer compound that is evenly coated on the leather / textile surface. It forms one or more layers of film on the leather / fabric surface by adhesion. Therefore, the quality of the coating material not only directly affects the appearance and quality of the product, but also determines the performance of the product to a large extent. Polyacrylate emulsion has the characteristics of flexibility and elasticity in film formation, and the coating has the characteristics of light resistance, aging resistance, and excellent wet rub resistance. It is a kind of leather textile coating material widely used at present. However, due to the existence of some polar groups in traditional polyacrylate emulsions, and the inf...
