Problems solved by technology

[0004] 1. The organic solvent contained in the solvent-based powder surface treatment agent 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 powder surface treatment agent 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. The synthetic leather products prepared by solvent-based powder rubbing agent have poor comprehensive effects such as stability and hand feeling

Abstract

The invention discloses a water-based PU brush surface conditioning agent for synthetic leather, which comprises the following materials by weight percent: 10 to 20 percent of water-based stoving varnish resin, 1 to 6 percent of water-based polyurethane, 60 to 70 percent of water, 5 to 13 percent of silicon dioxide matting agent, 0.5 to 2 percent of organic silicon flatting agent, 1 to 5 percent of organic silicon foam killer and 2 to 6 percent of water-based modified polyethylene wax emulsion. In the water-based PU brush surface conditioning agent for synthetic leather, water is taken as solvent to replace noxious solvents, such as dimethyl formamide and butanone, so that the water-based PU brush surface conditioning agent has the performances of non-inflammation, safety, environmental protection and cost saving, and resin has the advantages of good film reforming property, firm bonding, solvent resistance, cold resistance, hydrolysis resistance and thermosenescence resistance of coating, and the finished product made of the surface conditioning agent has unique brush effect, strong dermis effect, water resistance and good air permeability.

Description

technical field [0001] The invention relates to a water-based PU resin for synthetic leather, in particular to a water-based PU powder surface treatment agent for synthetic leather used in the post-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 that the existence of the base fabric cannot be see...
