Abstract

The invention discloses environment-friendly water-based synthetic leather which sequentially comprises a surface layer, a middle layer and a base layer from outside to inside, the surface layer is obtained by coating water-based slag surface layer slurry; the middle layer is a one-layer bonding layer or two-layer foaming layers or a one-layer foaming layer and a one-layer bonding layer; the foaming layer is obtained by coating a water-based slag foaming layer; the bonding layer is obtained by coating water-based slag bonding layer slurry; the water-based residue is prepared by grinding coffee residues, dry flower residues and other domestic waste residues through low-temperature liquid nitrogen, adding water-based polyurethane resin and then carrying out high-speed shearing dispersion. One of the purposes of the invention is to provide the environment-friendly water-based synthetic leather which can effectively and repeatedly utilize waste residues in life and has no potential chemical hazard to a user, and the other purpose of the invention is to provide the production process of the environment-friendly water-based synthetic leather.

Description

technical field

[0001] The invention relates to the technical field of synthetic leather, in particular to an environment-friendly water-based synthetic leather and a production process thereof. Background technique

[0002] As a composite material that can replace animal leather, synthetic leather is superior to animal leather in terms of durability and high cost performance, making it highly acceptable in the consumer market and widely used in the production of shoes, boots, clothing, luggage and bags. and balls, etc. The traditional solvent-based synthetic leather manufacturing process cannot avoid organic solvent pollution, and its finished products have potential chemical hazards to users. With the increasing market demand for environmentally friendly synthetic leather products, great progress has been made in water-based synthetic leather manufacturing technology and product performance. As an important part of green synthetic leather, its market share is getting hig...
