Sodium potassium aluminosilicate/collagen composite material as well as preparation method and application thereof

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. 本发明公开了一种铝硅酸钾钠/胶原复合材料及其
