High-permeability PVC artificial leather and application thereof

Abstract

The invention discloses high-permeability PVC artificial leather and application thereof. The high-permeability PVC artificial leather is prepared from polyvinyl chloride, tetraethylenepentamine, modified polyvinyl chloride, a self-made adhesive, soybean protein, natural resin, vegetable oil, vinyl acetate-ethylene copolymer emulsion, a plasticizer, a stabilizer and a foaming agent. Polyvinyl chloride molecules subjected to chlorination treatment improve the thermal deformation temperature and the dissolving property of the material, and meanwhile, the processed material has good cohesiveness; the chlorinated polyvinyl chloride is modified by tetraethylenepentamine, so that the tensile strength of the material is enhanced to the maximum extent; the self-made adhesive utilizes vinyl acetate-ethylene copolymer emulsion, modified natural resin, modified vegetable oil and modified soybean protein, so that the peel strength of the PVC artificial leather is improved; and when the artificial leather is prepared, calendaring film forming and foaming treatment on the two sides are carried out at the same time, the foaming treatment provides more pressure for calendaring film forming, so that the material and the cloth base are combined more tightly, and the foaming time is shortened.

Description

technical field [0001] The invention relates to the technical field of PVC artificial leather, in particular to a high-permeability PVC artificial leather and its application. Background technique [0002] With the continuous progress and development of PVC production and processing technology, PVC artificial leather has not only greatly improved in quality, but also has an increasing variety of designs and colors. PVC artificial leather with high permeability is very popular, but excessive pursuit of high permeability will affect other properties of PVC artificial leather, such as tensile resistance, peel strength, cold resistance, high temperature resistance, etc. [0003] Therefore, for the performance optimization of high-permeability PVC artificial leather, the performance is improved without affecting its permeability, and it has a good development prospect. Therefore, it is very necessary to prepare a high-permeability PVC artificial leather with high tensile strengt...
