Problems solved by technology

[0004] 1. The organic solvent contained in the solvent-based cashmere resin will cause the bottom layer of synthetic leather or artificial leather to dissolve, and the treated synthetic leather will not feel good;
[0005] 2. The organic solvent contained in the solvent-based velvet resin not only has high cost, strong smell, and is easy to pollute the environment, but also has safety hazards such as flammability and explosion;
[0006] 3. Synthetic leather products prepared by solvent-based cashmere resin have poor comprehensive effects such as viscosity, stability, and hand feeling

Abstract

The invention discloses an aqueous PU velvet resin used for synthetic leather, which comprises the following raw materials by weight percent: 40-50% of aqueous polyurethane resin, 40-50% of water, 2-5% of low-temperature sheep bar powder, 2-4% of silicon dioxide velvet powder, 1-3% of organic silicone oil smoothing agent, 1-4% of extinction powder, 0.5-1% of organic silicon flatting agent, 2-5% of organic silicon antifoaming agent and 0.5-2% of aqueous polyurethane thickening agent. The aqueous PU velvet resin used for synthetic leather of the invention takes water as solvent to replace toxic solvent, such as dimethyl fomamide, butanone and the like and has the advantages of being non-combustible, safe and environment-friendly, saving cost and the like. The aqueous PU velvet resin also has the advantages of good film-forming resistance, firm bonding, coating solvent resistance, cold resistance, hydrolysis resistance and heat-proof aging. Products fabricated by using the resin have the characteristics of plump feel, unique velvet effect, strong real leather quality, fine and smooth texture, good air permeability and the like.

Description

Technical field [0001] The invention relates to a velvet-feel resin for synthetic leather, in particular to a synthetic leather water-based PU velvet-feel resin applied to a synthetic leather front process. Background technique [0002] With the continuous improvement of people’s living standards, high-end, safe and environmentally friendly daily-use products have become people’s goals. For example, leather bags, leather shoes and leather clothing are commonly used products. As the world’s awareness of animal protection increases, Animal leather is far from meeting people's needs. Synthetic leather products have gradually become a popular trend in the future. Synthetic leather has been widely used in the production of luggage, clothing, shoes and other products. Among them, the base fabric of PU leather is a canvas PU material with good tensile strength. In addition to being coated on the top of the base fabric, the base fabric can also be included in the middle, so that the exis...
