Abstract

The nanometer material leather assistant consists of nanometer material 1-60 wt%, moistener 1-30 wt%, dispersant 1-80 wt% and adhesive 1-30 wt%. During tanning, the nanometer material produces photocatalysis to decompose fungi, bacteria and matters causing decay and smelling, and makes leather possess antifungus, antiseptic, wash resisting and other functions.

Description

Technical field: [0001] The invention relates to a leather auxiliary agent, in particular to a leather auxiliary agent containing nanometer materials. Background technique: [0002] At present, none of the additives used for tanning contain nano-materials, and the leather made with them does not have the functions of anti-mildew and sterilization. Therefore, when encountering mold to produce mildew, it is difficult to handle, shortening the service life of leather products, also limiting the use of leather, and greatly reducing the application field of leather. Invention content: [0003] The purpose of the present invention is to overcome above-mentioned deficiencies in prior art and provide a kind of performance that can improve leather, make leather have antifungal and antibacterial function, and waterproof, oilproof, dustproof, washable nano-material leather auxiliary agent. [0004] The object of the present invention can be achieved by following measures: nano mater...
