Abstract

The invention discloses environment-friendly polyvinyl chloride artificial leather. The environment-friendly polyvinyl chloride artificial leather comprises a cloth base and a coating coated on the cloth base, wherein the coating is prepared from the following components in parts by weight of 50 to 80 parts of polyvinyl chloride resin, 10 to 15 parts of nano calcium oxide, 5 to 10 parts of ethylene-ethyl acrylate copolymer, 2 to 5 parts of dibutyltin dilaurate, 15 to 20 parts of barium stearate, 8 to 12 parts of polyisobutylene poly-succinimide, 4 to 6 parts of boron oxide and 3 to 8 parts of tributyl citrate plasticizer. The tributyl citrate plasticizer adopted by the invention has the advantages of good compatibility with PVC, good plastic low-temperature flexural property, high thermal stability, environmental protection and no toxicity; and the formula of the polyvinyl chloride surface layer and the foaming layer is optimized, so that the internal structure of the PVC artificial leather is improved to the microscopic degree, and the PVC artificial leather has excellent mechanical properties.

Description

technical field [0001] The invention relates to the technical field of leather processing, in particular to a green and environment-friendly polyvinyl chloride artificial leather and a preparation method thereof. Background technique [0002] At present, phthalate plasticizers are mostly used in the processing of PVC artificial leather. During use, the plasticizers will gradually migrate to the surface of the product and come into contact with the human body. Phthalates are mainly used in polyvinyl chloride materials to change polyvinyl chloride from hard plastic to elastic plastic and act as a plasticizer. It is widely used in hundreds of kinds of toys, food packaging materials, medical blood bags and hoses, vinyl floors and wallpapers, cleaners, lubricants, personal care products (such as nail polish, hair spray, soap and shampoo), etc. products, but have serious harm to human health. Phthalates are toxic to reproduction, mutagenic and carcinogenic, and pose a major thre...
