Abstract

The invention discloses an oxidation-resistant antibacterial leather paint which is prepared from the following raw materials in parts by weight: 1-2 parts of aluminum dihydrogen phosphate, 0.7-1 part of zinc dialkyl dithiophosphate, 0.1-0.3 part of 2-bromo-4-methylphenol, 0.1-0.2 part of trimethyl hydroxyethyl ethylenediamine, 1.7-2 parts of polyvinylpyrrolidone, 0.8-1 part of polyacrylamide, 1.6-2 parts of stannous chloride, 0.1-0.13 part of triethanolamine, 190-200 parts of methyl methacrylate, 3-4 parts of lauryl sodium sulfate, 0.1-0.2 part of urotropine, 0.2-0.3 part of ammonium persulfate, 16-20 parts of zinc acetate, 4-7 parts of silver nitrate, 0.8-1 part of sodium fluorborate, 0.7-1 part of polyoxyethylene oleate, 0.1-0.2 part of n-salicylanilide and 6-7 parts of 20-25% formaldehyde solution. The paint has the advantages of favorable antibacterial property, excellent water vapor permeability and excellent water resistance. The leather coated by the obtained emulsion has favorable antibacterial property and excellent hygienic property.

Description

technical field [0001] The invention relates to the technical field of leather coatings, in particular to an anti-oxidation and 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...
