Water-based PU Nubuck high-temperature foamex for synthetic leather

Abstract

The invention discloses a water-based PU Nubuck high-temperature foamex for synthetic leather, which comprises the following materials by weight percent: 30 to 40 percent of water-based polyurethane resin, 40 to 50 percent of water, 2 to 10 percent of high-temperature Nubuck foam powder, 2 to 5 percent of organic silicon flatting agent, 2 to 5 percent of organic silicon foam killer, and 0.5 to 2 percent of water-based polyurethane thickening agent. For the water-based PU Nubuck high-temperature foamex for the synthetic leather, the mixture ratio of the components is scientific and reasonable, and the components are coordinated with each other and act together. The Nubuck high-temperature foamex for synthetic leather has the advantages of good film reforming property, firm bonding and solvent resistance, cold resistance, hydrolysis resistance and thermosenescence resistance of coating. By adopting the finished product of the synthetic leather, the surface of which is treated by water-based PU Nubuck high-temperature foamex, the original effect of the leather surface is not affected. After the leather surface is treated by the PU Nubuck high-temperature foamex, Nubuck leather is produced through high-temperature foaming, the effect is unique, the texture of the synthetic leather is fine and smooth, and the synthetic leather has good comprehensive effects of good air permeability, good hand feel, water resistance, cohesiveness and the like.

Description

technical field [0001] The invention relates to a water-based PU Yangbuck high-temperature foaming resin for synthetic leather, in particular to a water-based PU Yangbuck high-temperature foaming resin for synthetic leather used in the back-stage process of synthetic leather. Background technique [0002] With the improvement of people's living standards, people are gradually pursuing high-quality daily products, and the demand for leather products is increasing. With the enhancement of animal protection awareness, animal leather can no longer meet people's needs. At present, synthetic leather products have gradually become a popular trend in the future. Synthetic leather has been widely used in the production of luggage, clothing, footwear and other products. The base fabric of PU leather is canvas PU material with good tensile strength. In addition to being coated on the base fabric In addition to the upper surface, the base fabric can also be included in the middle, so th...

AI Technical Summary

Problems solved by technology

[0004] 1. The organic solvent contained in the solvent-type Yangbuck high-temperature foaming 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-type Yangba high-temperature foaming 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 Yangbuck high-temperature foaming resin have poor comprehensive effects such as viscosity, stability, and hand feel.
