Embodiment 1

[0021] The water-based mirror leather is made by a dry film transfer processing method, including the following steps: coating water-based polyurethane resin slurry on release paper. The water-based polyurethane resin slurry is divided into three layers, namely the surface layer, the middle layer and the bottom layer. Layer, then bond the leather base cloth, separate the paper and leather, and inspect the storage.

[0022] The surface layer is made of the following raw materials in parts by weight: 100 parts of water-based polyurethane resin; 8 parts of pigments; 3 parts of thickener, 1 part of defoamer; 1 part of leveling agent; 2 parts of wetting agent.

[0023] The middle layer is made of the following parts by weight of raw materials: 100 parts of water-based polyurethane resin, 5 parts of pigments; 3 parts of thickener, 2 parts of foaming agent; 2 parts of foam stabilizer; 5 parts of curing agent.

[0024] The bottom adhesive layer uses water-based polyurethane adhesive with a c...

Abstract

The invention discloses waterborne shiny leather which is made in a dry-method film moving machining method. The method comprises the following steps that waterborne polyurethane resin slurry is arranged on release paper in a coating mode, the waterborne polyurethane resin slurry is divided into three layers, namely the face layer, the middle layer and the bottom adhesive layer, then a leather base cloth is bonded, paper and leather are separated, and the leather is detected and stored in a bin. The waterborne shiny leather has the advantages that besides the waterborne polyurethane resin utilization, the surface of the waterborne shiny leather is transparent, the surface brightness is high, and the surface has no crease line, the hydrolysis resistance of a synthetic leather product can be maintained for 5 years, the content of VOC is zero, no cell and needle eye exists in the surface of produced shiny synthetic leather, the surface is flat and smooth, similar products of other enterprises can not achieve the effect, and the waterborne shiny leather can be widely applied to various fields of sofas, automobile internal decoration, office appliances, and household walls.

Description

technical field [0001] The invention belongs to the field of leather, in particular to a water-based mirror leather. Background technique [0002] At present, after years of development, polyurethane synthetic leather has been widely used in home furnishing, sofas, car interiors, bags, etc. , Office supplies, etc. [0003] Currently existing mirror leather patents, the resins used are all solvent-based polyurethane resins. Solvent-based polyurethane resin refers to a polymer resin dissolved in an organic solvent, but the solvent of the solvent-based resin pollutes the environment; most of the organic solvents are flammable and explosive chemicals, causing safety accidents; organic solvents are toxic and harmful, affecting construction Personnel are healthy, and solvent residues endanger the safety of users. [0004] The use of solvent-based resins in the synthetic leather industry has caused serious consequences. China’s DMF output in 2011 was 725,000 tons, and the output...
