Abstract

The invention discloses environment-friendly artificial leather characterized in that the artificial leather comprises a base cloth layer and a surface layer which are connected through a bonding layer; raw materials of the surface layer comprise, by weight, 100 parts of polyvinyl chloride resin, 15 to 25 parts of a pyrido[1,5-A]-1,3,5-triazine-2,4(1H,3H)-diketone/sulfuryl isocyanate polycondensate, 10 to 15 parts of amino-terminated hyperbranched polyamide, 10 to 20 parts of an environment-friendly plasticizer, 3 to 5 parts of silicon boride, 8 to 12 parts of pearl powder, 1 to 3 parts of a coupling agent and 2 to 5 parts of a foaming agent. The invention also discloses a preparation method of the environment-friendly artificial leather. The environment-friendly artificial leather disclosed by the invention is good in comprehensive performance, good in wear resistance, cold resistance, impact resistance, fine and smooth texture, stereoscopic impression and softness, excellent in performance stability, long in service life and high in economic value, social value and ecological value.

Description

technical field [0001] The invention relates to the technical field of synthetic leather, in particular to an environment-friendly artificial leather and a preparation method thereof. Background technique [0002] In recent years, with the development of the economy and the improvement of living standards, people's requirements for decorative materials are getting higher and higher, and the demand for leather products is increasing. Leather is not only a tool that can be used to shelter from the cold, but also a A means for people to advertise their achievements, it is a symbol of fashion nobility. Leather includes natural leather and artificial leather according to its source. Natural leather mainly comes from animal fur, which is limited in quantity and expensive. Artificial leather is artificially synthesized leather, which simulates the tissue structure and performance of natural leather, and can be used as a suitable material for leather substitutes. It is generally a...
