Environment-friendly synthetic leather

Abstract

The invention provides environment-friendly synthetic leather which comprises a base cloth layer, a waterproof layer and a surface layer, wherein the base cloth layer is uniformly arranged in thickness, the base cloth layer is a non-woven fabric, and the non-woven fabric is prepared from 40-50 parts of fibrilia, 45-50 parts of carbon fibers and 5-15 parts of thermoplastic fibers. The fibrilia, thecarbon fibers and the thermoplastic fibers are uniformly mixed, unloosened, punctured, immersed and sized to prepare the non-woven fabric and entangle by needling. Polyurethane resin uniformly permeates the non-woven fabric, a waterproof layer is uniformly coated to the surface of the base cloth layer, and the waterproof layer is formed by spraying and drying a waterproof agent solution. The waterproof agent solution comprises 60-70 parts of a polypropylene fiber oil agent and 30-40 parts of waterborne polyurethane resin. The surface layer is coated to the surface of the waterproof layer andis embossed and dyed. Due to the adoption of the environment-friendly synthetic leather, gas harmful to human body in a using process can be avoided, and the environment-friendly synthetic leather hasrelatively good environmental friendliness.

Description

technical field [0001] The invention relates to the field of synthetic leather, in particular to an environment-friendly synthetic leather. Background technique [0002] At present, synthetic leather is widely used in the fields of clothing, vehicles and home decoration, and has a good application prospect. However, synthetic leather has the following disadvantages: synthetic leather preparation raw materials contain volatile toxic substances, causing synthetic leather products to volatilize harmful gases during use, which is harmful to human health; (2) the preparation process of existing synthetic leather is relatively complicated , At the same time, the energy consumption is high, resulting in low production efficiency and high production cost. Therefore, it is necessary to design a kind of environmental protection synthetic leather. Contents of the invention [0003] In view of the above situation, the present invention provides an environmentally friendly synthetic ...
