Abstract

The invention provides a saponified antibacterial leather coating. The saponified antibacterial leather coating is composed of the following raw materials in parts by weight: 1 to 2 parts of butyl benzyl phthalate, 0.3 to 1 part of polyethylene benzenesulfonic acid, 1.7 to 2 parts of polyvinylpyrrolidone, 0.8 to 1 part of polyacrylamide, 1.6 to 2 parts of stannous chloride, 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 Urotropine, 0.2 to 0.3 part of ammonium persulfate, 6 to 7 parts of a formaldehyde solution with a concentration of 20 to 25%, 16 to 20 parts of zinc acetate, 4 to 7 parts of silver nitrate, 0.8 to 2 parts of polyether glycol, 1 to 2 parts of sodium myrastate, 0.1 to 0.2 part of nonylphenol, 0.8 to 1 part of ammonium zirconium carbonate, 0.1 to 0.3 part of hexamethyl cyclotrisiloxane and 1 to 2 parts of sodium hydroxide with a concentration of 3 to 5 mol / l. The saponified antibacterial leather coating provided by the invention has good antibacterial properties and excellent water vapor permeability and water resistance; and the leather coated by an emulsion has good antibacterial properties and excellent hygienic properties.

Description

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