Abstract

The invention discloses a decorative antibacterial leather coating. The decorative antibacterial leather coating is prepared from the following raw materials in parts by weight: 0.7 to 1 part of ammonium metaborate, 1.7 to 2 parts of polyvinylpyrrolidone, 0.8 to 1 part of polyacrylamide, 0.1 to 0.13 part of triethanolamine, 190 to 200 parts of methyl methacrylate, 3 to 4 parts of sodium dodecyl sulfate, 0.1 to 0.2 part of urotropin, 0.2 to 0.3 part of ammonium persulfate, 6 to 7 parts of 20 to 25 percent formaldehyde solution, 16 to 20 parts of zinc acetate, 4 to 7 parts of silver nitrate, 1.6 to 2 parts of microcrystalline wax, 0.8 to 1 part of dodecyl trimethyl ammonium chloride, 0.1 to 0.2 part of trimethylolpropane, 0.1 to 0.2 part of guaiacol, 1 to 2 parts of butyl oleate, 2 to 3 parts of ash calcium powder and 1.6 to 2 parts of stannous chloride. The coating disclosed by the invention has good bacteria resistance and excellent water vapor permeability and water resistance; a leather coated by obtained emulsion is good in bacteria resistance and excellent in sanitary property.

Description

technical field [0001] The invention relates to the technical field of leather coatings, in particular to a decorative 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 influenc...
