Abstract

The invention discloses PVC foamed artificial leather and a preparation method thereof. The PVC foamed artificial leather comprises, by mass, 100 parts of PVC or crosslinking powder, 60-120 parts of plasticizer, 0.1-10 parts of thermal stabilizer, 3-10 parts of AC foamer, 1-15 parts of pigment and 0.1-0.5 part of foam hole adjuster, wherein the plasticizer is one of or a mixture of DOP, DINP and DOA, and the thermal stabilizer is one of or a mixture of barium stearate, cadmium stearate, zinc stearate and lead stearate. Compared with the prior art, the PVC foamed artificial leather is high in thickness which can meet requirements of clients on finished product thickness being 3.0mm and above to meet special using requirements like saddles.

Description

technical field [0001] The invention belongs to the technical field of artificial leather manufacture, and in particular relates to a PVC foamed artificial leather and a preparation method thereof. Background technique [0002] Existing PVC is mainly composed of PVC and plasticizers, fillers, etc. The thickness of the finished product is about 1.0mm, and there are basically no thick products. Contents of the invention [0003] Purpose of the invention: the present invention aims at the deficiencies in the prior art, and proposes a thicker PVC foamed artificial leather and a preparation method thereof. [0004] Technical solution: A PVC foamed artificial leather according to the present invention comprises the following components in parts by mass: 100 parts of PVC or cross-linking powder, 60-120 parts of plasticizer, 0.1-10 parts of heat stabilizer, AC hair Foam agent 3-10 parts, coloring material 1-15 parts, cell regulator 0.1-0.5 parts. [0005] Further, the plasticize...
