Problems solved by technology

[0002] In terms of TPE material production technology, the expansion ratio of existing TPE materials is basically above 1. The current TPE materials cannot achieve the micro-foaming effect, especially the micro-foaming effect with a foaming ratio of less than 1.
In addition, the existing TPE materials are generally difficult to achieve continuous foaming, and they are all foamed in batches, and the production efficiency is low.

Abstract

The invention discloses microfoam TPE artificial leather and a production method thereof. The microfoam TPE artificial leather is prepared from a TPE base material and a TPE fabric attached to the surface of the TPE base material; the TPE base material is prepared from the following components in parts by weight: 40-50 parts of TPE, 10-15 parts of EVA, 30-35 parts of POE, 10-15 parts of talcum powder, 0.5-0.8 part of stearic acid, 1-1.5 parts of zinc oxide, 0.5-0.8 part of PE wax, 2-5 parts of color master batch and 1-3 parts of foaming agent; and the TPE fabric is prepared from the followingcomponents, in parts by weight: 50-60 parts of TPE, 10-15 parts of EVA, 30-35 parts of POE, 0.5-1 part of stearic acid, 1.5-2.5 parts of zinc oxide, 0.5-0.8 part of PE wax, 2-5 parts of color master batch and 0.5-1 part of a tasteless vulcanizer. The TPE material can be smoothly produced by a calender as well as subjected to microfoaming by a hub type continuous vulcanizer through formula regulation and setting of technological conditions, the microfoam TPE artificial leather with the multiplying power being less than 1 is continuously produced by setting the technological conditions, and themicrofoam TPE artificial leather is applicable to environment-friendly products such as ready-made clothes, mountaineering packsacks and slaughtering aprons.

Description

technical field [0001] The invention relates to a thermoplastic elastomer material technology, in particular to a microfoamed TPE artificial leather and a manufacturing method thereof. Background technique [0002] In terms of TPE material production technology, the expansion ratio of existing TPE materials is basically above 1. The current TPE materials cannot achieve the micro-foaming effect, especially the micro-foaming effect with a expansion ratio of less than 1. In addition, the existing TPE materials are generally difficult to achieve continuous foaming, and they are all sheet-like batches of foaming, and the production efficiency is low. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, one of the objectives of the present invention is to provide a microfoamed TPE artificial leather. The technology of the invention is mainly to adjust the formula of the TPE material which is difficult to continuously foam, not only can the ...
