Problems solved by technology

However, at present, when PVC artificial leather undergoes hot-press discoloration, the discoloration contrast is far lower than that of PU artificial leather, and the service life of PVC artificial leather after hot-press discoloration is further shortened, which greatly reduces the high-end market application of PVC.

Abstract

The invention discloses a dry process PVC hot-pressing color changing artificial leather manufacturing technology. The dry process PVC hot-pressing technology is utilized for preparing artificial leather, and through accurate control over raw material layer matching and hot-pressing technology parameters, the hot-pressing color changing artificial leather is obtained. The prepared PVC artificial leather comprises a five-layer structure sequentially including a PVC face layer, a bubble layer, a PVC bottom layer, a bonding layer and a cloth layer. Through technology parameter adjustment, the hot-pressing color changing capability is improved, and meanwhile abrasion resisting performance of the artificial leather is improved.

Description

technical field [0001] The invention relates to the technical field of artificial leather processing, in particular to a manufacturing process of dry-process PVC heat-pressing discoloration artificial leather. 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. [0003] Among them, PVC artificial leather refers to the artificial leather produced with PVC resin as raw material, which is called PVC artificial leather; at present, the cost of PVC artificial leather on the market is far lower than that of PU artificial leather. Due to its low price, its application is becoming more and more extensive, especially in Automobile manufacturing industry. But at present, when PVC artificial leather undergoes...
