AI Technical Summary

Problems solved by technology

[0004] 1. The organic solvent contained in the solvent-based wax 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 solvent-based wax resin not only has high cost, strong odor, 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 wax resins have poor comprehensive effects such as viscosity, stability, and hand feel.

Abstract

The invention discloses a waterborne PU high smooth wax resin for synthetic leather and the resin comprises the following raw materials by weight percent: 30-40% of waterborne silicon-fluorine resin,20-30% of waterborne polyurethane, 10-30% of water, 0.2-0.8% of waterborne wax emulsion, 1-3% of organic silicone oil smoothing agent, 0.5-1% of organic silicone flatting agent, 2-5% of organic silicone defoamer and 0.5-2% of waterborne polyurethane thickener. The waterborne PU high smooth wax resin for synthetic leather provided by the invention uses water as solvent instead of toxic solvents such as dimethyl formamide, butanone and the like and has the advantage of noninflammability, safety, environmental protection, cost-saving and the like. The finished product prepared from the waterbornePU high smooth wax resin for synthetic leather provided by the invention has full hand feeling, high luster and high luminance, extremely smooth waxy feeling, delicate texture and good air permeability; and the prepared synthetic leather has good comprehensive effect in hand feeling, smoothness, water resistance, waxy feeling and the like.

Description

technical field [0001] The invention relates to a wax resin for synthetic leather, in particular to a water-based PU high-smooth wax resin for synthetic leather used in the front-end process of synthetic leather. Background technique [0002] At present, synthetic leather products have gradually become a popular trend in the future, and synthetic leather has been widely used in the production of luggage, clothing, footwear and other products. 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 existence of the base fabric cannot be seen from the outside. PU leather has physical properties. Good, resistance to twists and turns, good softness, high tensile strength, and breathability, so PU leather is widely used in the fabric of footwear or the weight-bearing parts of bags. [0003] At present, the wax resins for synthetic l...
