Problems solved by technology

Generally, when using PVC to prepare the leather foam layer, some fillers, such as calcium carbonate powder, etc., will be added. The filler mainly plays a role in reducing costs. There is no significant advantage in dispersibility, and the toughness and strength of the prepared PVC foam layer are not easy to grasp, and the dimensional stability is not good.

Embodiment 1

[0017] A PVC artificial leather foam layer, the foam layer comprises the following components by weight: 98 parts of PVC resin powder, 33 parts of polyphenylene ether ketone, 7 parts of nano-alumina, 32 parts of plasticizer, 2.3 parts of stabilizer part, blowing agent 4.2 parts. The plasticizer can be DOP. A method for preparing a PVC artificial leather foam layer, the steps are as follows: (1) Primary heating and mixing: first, polyphenylene ether ketone and nano-alumina are uniformly mixed in a mixing tank according to parts by weight, and are ready for use. The temperature of the mixing tank was kept at 152°C, and the mixing time was 32 minutes. (2) Secondary mixing: Send PVC resin powder, plasticizer, stabilizer, and foaming agent into the mixing kettle according to parts by weight for uniform mixing, and the mixing time is 22 minutes. (3) Three-stage mixing: send the mixture in step (1) and step (2) into the mixing tank for mixing, and the time for mixing in the mixing ...

Abstract

The invention discloses a PVC artificial leather foaming layer. The PVC artificial leather foaming layer comprises, by weight, 95-105 parts of PVC resin, 30-40 parts of polyphenylene ether ketone, 5-10 parts of nano aluminum oxide, 30-40 parts of plasticizer, 2-3 parts of stabilizer and 4-5 parts of foaming agent. A preparation method of the PVC artificial leather foaming layer includes the steps of firstly, performing primary heating mixing; secondly, performing secondary mixing; thirdly, performing tertiary mixing; fourthly, performing smelting and open milling; fifthly, rolling, and cooling to obtain the PVC artificial leather foaming layer. The PVC artificial leather foaming layer and the preparation method thereof have the advantages that the dimensional stability, strength and toughness of the whole foaming layer are increased, and the foaming layer is good in softness and has certain strength at the same time, and the breathability of the foaming layer is enhanced comprehensively by the porous-structured nano aluminum oxide.

Description

technical field [0001] The invention relates to PVC foamed artificial leather and a preparation method thereof. Background technique [0002] At present, with the rapid development of the clothing industry, people are very enthusiastic about the pursuit of leather clothing, but the price of genuine leather leather clothing is high and difficult to maintain, so the demand for artificial leather and synthetic leather is gradually increasing, and due to the softness of PU synthetic leather Good texture and strong three-dimensional characteristics, so it is widely used in the manufacture of leather clothing. In the synthetic leather industry, a large part of PU synthetic leather is processed by wet kneading process, but with the hydrolysis of PU synthetic leather, the product price is relatively expensive and technical problems such as the inability to produce coarse grain products have appeared. Since 2005 The production of domestic PU synthetic leather has a certain degree of...
