Abstract

The invention discloses graphene superfine fiber, polyurethane synthetic leather and a preparation method. The fiber is prepared from, by weight, 20-25 parts of polyurethane resin, 5-10 parts of graphene, 1-6 parts of wood powder, 0.5-3 parts of an ion active agent, 1-3.4 parts of a non-ion active agent, 15-20 parts of a DMF solvent, 5-10 parts of color paste and 1 part of a base fabric. By arranging different raw materials of the synthetic leather and setting the ratio of the raw materials, the wear resistance and breathability of synthetic leather can be improved, and therefore the whole using effect of the synthetic leather can be improved integrally, and the using comfort is improved; due to the synthetic leather preparation method, the traditional wet method preparation of synthetic leather is simplified, the preparation production cost is lowered, and the preparation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of synthetic leather, in particular to a graphene superfine fiber, polyurethane synthetic leather and a preparation method. Background technique [0002] Synthetic leather is a plastic product that simulates the composition and structure of natural leather and can be used as its substitute material. Usually, the impregnated non-woven fabric is used as the mesh layer, and the microporous polyurethane layer is used as the grain layer. Its front and back are very similar to leather, and has a certain degree of air permeability, which is closer to natural leather than ordinary artificial leather. Widely used in making shoes, boots, bags and ball games. [0003] In the preparation process of the existing synthetic leather, the synthetic leather generally uses polyurethane as the main synthetic material for operation, and the air permeability of the synthetic leather is generally average, and the wear resistance...
