Abstract

The invention discloses a sodium potassium aluminosilicate / collagen composite material as well as a preparation method and application thereof. The sodium potassium aluminosilicate / collagen composite material is prepared from 3 to 30 parts of superfine sodium potassium aluminosilicate powder, 50 to 200 parts of aromatic polyurethane resin emulsion, 10 to 60 parts of collagen extracting solution, 1 to 5 parts of sodium tripolyphosphate, 2 to 8 parts of sodium carboxymethyl cellulose and 1 to 5 parts of silane coupling agent. The superfine sodium potassium aluminosilicate / collagen composite material is used for repairing the leather, has good compatibility with the leather and similar hand feeling, and can endow the leather with more natural hand feeling, the wear resistance of the prepared finished leather is greater than or equal to grade 4, the dry / wet rubbing resistance is greater than or equal to grade 4-5, and the dynamic waterproof frequency is greater than or equal to 10000 times.

Description

technical field [0001] The invention relates to the technical field of tanning, in particular to a sodium potassium aluminosilicate / collagen composite material and a preparation method and application thereof. Background technique [0002] Polyurethane resins are commonly used in the retanning and finishing stages of the tanning industry. The polyurethane resin used in the finishing process can be used in repairing, middle layer, upper layer, bright layer, etc. due to its excellent film-forming properties, stability, and physical and mechanical properties. Adding inorganic fillers and crosslinking agents to enhance the physical and mechanical properties of polyurethane resins is a common method to improve the overall performance of polyurethane resins. At present, inorganic fillers such as silica and talc are commonly used to reinforce polyurethane resins. Usually, inorganic fillers are obtained from natural minerals through ball milling or laser cutting. However, the comp...
