Abstract

The invention discloses a TPU modified PVC foaming material, artificial leather and a preparation method of the artificial leather, and the TPU modified PVC foaming material comprises the following components in parts by weight: 5-50 parts of TPU, 50-100 parts of PVC, 40-100 parts of DOP (dioctyl phthalate), 1-5 parts of an AC (azodicarbonamide) foaming agent and 1-3 parts of a calcium-zinc stabilizer. The TPU modified PVC foaming material disclosed by the invention is excellent in friction resistance, cold resistance and the like, and only one layer of TPU modified PVC foaming material can be used for replacing a surface layer and a foaming layer in existing PVC artificial leather.

Description

technical field [0001] The invention relates to the field of artificial leather, in particular to a TPU modified PVC foam material, artificial leather and a preparation method for the artificial leather. Background technique [0002] Artificial leather is a plastic product that looks and feels similar to leather and is widely used in furniture, handbags, clothes, car interiors, etc. Among them, foamed artificial leather is generally used in automotive interiors and furniture fabrics. Foamed artificial leather not only requires the surface to have excellent friction resistance, cold resistance, and aging resistance, but also requires a certain degree of softness and elasticity to improve the touch. and user experience. Therefore, at present, the foamed artificial leather is generally composed of a surface layer, a foam layer and a base cloth layer. The layer mainly provides a certain elasticity and softness. The surface layer and the foam layer can be prepared with similar...
