Abstract

The invention discloses a TPE artificial leather, which comprises a base cloth, and the upper surface of the base cloth is provided with a TPE base material layer and a TPE fabric layer sequentially from bottom to top; the TPE base material layer is calculated by mass percentage. prepared from the following components: SEBS 40%-65%, ethylene-octene copolymer 15%-30%, EVA 10%-20%, calcium carbonate 14-16%, stearic acid 0.5-1.5%, oxidation Zinc 2-3%, PE wax 0.5-1%, vulcanizing agent 0.5-1.5%, foaming agent 2%-5%, EVA masterbatch 2%-5%; the TPE fabric layer is composed of Prepared from the following components: SEBS 40%-70%, ethylene-octene copolymer 15%-30%, EVA 10%-20%, calcium carbonate 14-16%, stearic acid 0.5-1.5%, Zinc oxide 2‑3%, PE wax 0.5‑1%, vulcanizing agent 0.5‑1.5%, EVA masterbatch 2%‑5%. The invention also discloses a preparation method of the TPE artificial leather. The TPE artificial leather of the invention can be foamed continuously and has the characteristics of high foaming ratio, degradability and good mechanical properties.

Description

technical field [0001] The invention relates to an artificial leather, in particular to a TPE artificial leather and a preparation method thereof. Background technique [0002] Artificial leather is a plastic product that looks and feels like leather and can be used instead of it. It is usually made of fabric as the base, coated with synthetic resin and various plastics. There are mainly three types of PVC artificial leather, PU artificial leather and PU synthetic leather. TPE material is a material that has the high elasticity, high strength and high resilience of rubber, and has the characteristics of injection molding. In the prior art, since the TPE material is an open cell, if the continuous foaming method of the existing foaming furnace cannot produce complete cells, unless batch foaming is used, but there are many time-consuming, low efficiency, and cost High disadvantage. Contents of the invention [0003] In order to overcome the deficiencies of the prior art,...
