Abstract

The invention discloses wear-resistant leather and a preparation method thereof. The wear-resistant leather comprises a base fabric, an adhesive layer, a foaming layer, a surface layer and a surface treatment layer, wherein the surface layer comprises the following raw materials in parts by weight: 100 parts of polyvinyl chloride paste resin powder having a polymerization degree of 1600-2000, 60-80 parts of a plasticizer, 1-3 parts of a heat stabilizer and 3-5 parts of color paste; the surface treatment layer comprises the following raw materials in parts by weight: 80-90 parts of water-based polycarbon type PU resin, 15-20 parts of aliphatic polyurethane, 4-6 parts of an aziridine crosslinking agent, 3-5 parts of an isocyanate-based crosslinking agent, 15-20 parts of water-based silicone hand feeling agent, 6-8 parts of an acrylic thickening agent and 2-3 parts of a pH adjusting agent. The wear resistance and the mechanical fatigue resistance of the wear-resistant leather provided by the invention are improved by mainly improving the surface layer, the surface treatment layer, the foaming layer and the preparation method of the original polyvinyl chloride artificial leather.

Description

technical field [0001] The invention relates to the technical field of leather, in particular to leather with high abrasion resistance and a preparation method thereof. Background technique [0002] At present, most of the leather products on the market are ordinary polyvinyl chloride artificial leather. However, with the continuous progress of the automobile industry, its requirements for the required leather are getting higher and higher. The common PVC artificial leather on the market can no longer meet the high-strength wear resistance and sewing fatigue resistance of medium and high-end automotive interior fabrics. requirements. Therefore, how to improve properties such as wear resistance and sewing resistance on the basis of the original polyvinyl chloride artificial leather has become one of the technical problems urgently to be solved for the current polyvinyl chloride artificial leather. Contents of the invention [0003] One of the objectives of the present inv...
