Graphene superfine fiber polyurethane synthetic leather and preparation method thereof

Abstract

The invention discloses a graphene superfine fiber polyurethane synthetic leather and a preparation method thereof. The graphene superfine fiber polyurethane synthetic leather comprises a surface layer, a middle layer and an adhering layer which are respectively prepared from the following components of high-performance waterborne non-yellowing polyurethane resin, nylon, graphene, superfine fiberpolyurethane synthetic substrate, an abrasion-resistant agent, a light-resistant agent, a flame-retardant master batch and pure water. The preparation method comprises the following steps of S1, weighing the raw materials according to a ratio; S2, treating the graphene; S3, mixing and stirring the raw materials; S4, filtering the solution by a filtering net, and preparing an automobile superfine fiber leather by a dry type synthetic leather production line. The prepared graphene superfine fiber polyurethane synthetic leather has the advantages that the comprehensive property is excellent, thetesting result in each aspect is good, the physical indexes are basically the same with the physical indexes of common superfine fiber automobile interior trim, the moisture and air ventilating property is realized, the abrasion-resistant property is excellent, and the touch feel of the natural leather is realized.

Description

technical field [0001] The invention relates to the technical field of synthetic leather materials, in particular to a graphene superfine fiber polyurethane synthetic leather and a preparation method thereof. Background technique [0002] Microfiber leather is a newly developed high-grade artificial leather. It is developed on the basis of imitating the structure and chemical organization of natural leather. Microfiber leather is made of bundled superfine fibers and polyurethane through special processing. Nylon Or polyester superfine fiber is a three-dimensional three-dimensional skeleton, and polyurethane has a three-dimensional network structure of irregular micropores in the finished product. Chemical resistance, moisture absorption and drainage, stability, shape retention, automatic cutting processing and subsequent processing adaptability are superior to natural leather, and its density is small. Under the same thickness, the quality of microfiber leather is not as goo...

[0002] Microfiber leather is a newly developed high-grade artificial leather. It is developed on the basis of imitating the structure and chemical organization of natural leather. Microfiber leather is made of bundled superfine fibers and polyurethane through special processing. Nylon Or polyester superfine fiber is a three-dimensional three-dimensional skeleton, and polyurethane has a three-dimensional network structure of irregular micropores in the finished product. Chemical resistance, moisture absorption and drainage, stability, shape retention, automatic cutting processing and subsequent processing adaptability are superior to natural leather, and its density is small. Under the same thickness, the quality of microfiber leather is not as good as ordinary natural leather Two-thirds of the quality of leather can greatly save the cost of materials, but ordinary microfiber leather is made of synthetic leather by transfer coating of release paper, whether it is used in seats, sofas or home decoration, it is only used as a leather material
