Problems solved by technology

[0004] 1. The organic solvent contained in the solvent-based oil mist surface treatment agent will cause the bottom layer of synthetic leather or artificial leather to dissolve, and the treated synthetic leather has a bad hand feeling and a single effect;
[0005] 2. The organic solvent contained in the solvent-based matte 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. Synthetic leather products prepared by solvent-based matte surface treatment agents have poor comprehensive effects such as viscosity, stability, and hand feel.

Abstract

The invention discloses a water-based PU bright surface brush clear varnish for synthetic leather, which comprises the following materials in parts by weight: 35 to 45 parts of water-based polyurethane resin, 50 to 65 parts of water, 0.5 to 1 part of organic silicon flatting agent, and 2 to 5 parts of organic silicon foam killer. The water-based PU bright surface brush clear varnish has the advantages that the mixture ratio of the component is scientific and reasonable, and the components are coordinated with each other and act together; the bright surface brush clear varnish has the advantages of good film reforming property, firm bonding, solvent resistance, hydrolysis resistance and thermosenescence resistance of coating; the finished product made of the synthetic leather, the surface of which is treated by the bright surface brush clear varnish, has the advantages that the original effect of the leather surface is not affected, the treated leather surface has unique slippery effect, 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 glossy surface varnish for synthetic leather, in particular to a water-based PU glossy varnish 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 se...
