▎ 摘  要

NOVELTY - Mildew-proof wear-resistant environment-friendly polyvinyl chloride artificial leather comprises base cloth layer and polyvinyl chloride surface layer attached to the base cloth layer. The polyvinyl chloride surface layer comprises 100 pts. wt. polyvinyl chloride resin, 20-30 pts. wt. functional elastomer, 50-70 pts. wt. plasticizer, 12-20 pts. wt. coconut shell powder modified vermiculite powder, 4-12 pts. wt. crosslinking agent, 1-5 pts. wt. heat stabilizer, 1-3 pts. wt. antibacterial agent and 0.2-4 pts. wt. foaming agent. USE - Used as mildew-proof wear-resistant environment-friendly polyvinyl chloride artificial leather. ADVANTAGE - The leather: does not contain any volatile solvents; is environmentally friendly, and easy moldy and peeling of existing polyvinyl chloride leather; has smooth hand feel, strong three-dimensional effect, high gloss quality, excellent anti-mildew, antibacterial, abrasion resistance, long service life, and excellent economical and practicality; feels plump like real leather; meets the test standards; overcomes the problems of easy aging. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the leather, comprising (1) adding the raw materials for the preparation of the polyvinyl chloride surface layer into high-speed mixer, and performing high-speed mixing and stirring to prepare mixture, (2) transferring the mixture obtained in the step (1) to internal mixer for mixing, transferring to open mill for plasticization after the mixing is completed, and conveying to calender to be rolled into sheet, and (3) attaching the sheet material obtained in the step (2) to the base cloth layer to form semi-finished product, and transferring the semi-finished product to foam embossing machine for foam embossing treatment.
