Abstract

The invention discloses a novel PU and PVC mixed artificial leather and a preparation method and system thereof. The novel PU and PVC mixed artificial leather comprises a base layer; both the top andthe bottom of the base layer are covered with PU layers, and a PVC layer is arranged on the top of the PU layer on the top of the base layer. The PVC layer is prepared by the process of subjecting a PVC material to solid conveying, compacting, melting, shearing, mixing and extruding to mold through a screw extruder. Since the surface layer of the artificial leather is prepared from the PVC material, the defects of poor cold resistance and low physical property of the PVC material are overcome according to the characteristics of the wet-processed PU layer, the problem that the PU is not applicable to producing deep-grain products with animal grain or woven pattern is solved according to the character of high plasticity of the PVC material, further, poor grain three-dimension impression, poor sizing, hard touch, and severe shrinkage in thickness after PU is embossed are overcome, molding can be achieved without adding of plasticizers, the molded artificial leather is environmentally friendly, wear resistant and cold resistant, has soft surface, good performance and wide application range, and is good for users.

Description

technical field [0001] The invention relates to the technical field of artificial leather, in particular to a novel PU and PVC mixed artificial leather and a manufacturing method and system thereof. 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 a base, coated with synthetic resin and various plastics. There are mainly three types of PVC artificial leather, PU artificial leather and PU synthetic leather. , In the artificial leather market at this stage, PVC materials mainly focus on the low-end market, and high-end solid rubber wear-resistant scratch products. At this stage, PU materials generally exist in high-end, high-end and low-end markets. Low-end products have poor quality, poor durability, and are easy to weather and hydrolyze. High-end products The cost is high, the market acceptance is low, and the dosage is small. [0003] PVC solid rubber produ...
