Abstract

The invention discloses an anti-flaming antisepsis leather coating which is composed of, by weight, 2-3 parts of hydrous zinc borate, 1-1.5 parts of linoleic acid calcium soap, 0.1-0.2 part of triterpenoid saponin, 0.7-1 part of calcium naphthenate, 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, 6-7 parts of a 20%-25% formaldehyde solution, 16-20 parts of zinc acetate, 4-7 parts of silver nitrate, 1-2 part of decabromodiphenyl ether and 0.4-1 part of sodium lauryl sulfate. The anti-flaming antisepsis leather coating has a good antibacterial property and excellent moisture permeability and water resistance. Leather coated with the obtained emulsion is good in antibacterial property and excellent in hygiene property.

Description

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