Example Embodiment

[0019] Example 1

[0020] A calendering process for manufacturing PVC hot-pressed color-changing artificial leather includes the following steps:

[0021] S1. Weigh the raw materials of the PVC surface layer and the foam layer according to the weight ratio. The raw material composition of the PVC surface layer is: 100 parts by weight of PVC powder, 80 parts by weight of DOTP plasticizer, and 5 parts by weight of organic pigments, 2 parts by weight of barium zinc heat stabilizer,

[0022] The raw material composition of the foam layer is: 100 parts by weight of PVC powder, 60 parts by weight of DOTP plasticizer, 3 parts by weight of potassium-zinc heat stabilizer, 4 parts by weight of transparent organic pigment, and 7 parts by weight of foaming agent,

[0023] The bonding layer includes 100 parts by weight of polyurethane resin and 20 parts by weight of DOTP plasticizer;

[0024] S2. The raw materials of the weighed PVC surface layer are fully mixed, and then the PVC surface layer is o...

Abstract

The invention discloses rolling-process PVC hot-pressing color-changing artificial leather and a preparation process thereof. The artificial leather prepared through the preparation process comprisesa PVC surface layer, a foam layer, a bonding layer and a base cloth layer from outside to inside, wherein the PVC surface layer, the foam layer and the bonding layer are sequentially attached to the base cloth layer, and the rolling-process PVC hot-pressing color-changing artificial leather is prepared through line absorption cooling after foaming. The processing process of the artificial leatheris simplified, process cost is low, and process efficiency is high; and meanwhile, the artificial leather prepared through the preparation process can be subjected to hot-pressing color changing, is high in color change contrast ratio and good in wear resistance and has long service life.

Description

technical field [0001] The invention relates to the technical field of artificial leather processing, in particular to a manufacturing process of calendered PVC hot-press 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 hot-...
