Water PU polish processing agent for synthetic leather

Abstract

The invention discloses a water PU polish processing agent for synthetic leather, which is composed of the raw materials in the following weight percent: 10-20% of water acrylic acid resin, 10-20% of water baking finish resin, 50-60% of water, 3-5% of modified organic silicon polymer, 0.5-1% of organic silicon flatting agent, 2-5% of organic silicon defoaming agent, and 0.5-2% of water PU thickening agent. The proportion of each components of the water PU polish processing agent for synthetic leather provided by the invention is scientific and reasonable, the components coordinate mutually and exert synergic effects, the polish processing agent has the advantages of good film forming property, firm bonding, solvent-resisting, cold-resisting, hydrolysis-resisting, thermal ageing-resisting of the coating. The finished product made by using the polish processing agent provided by the invention to process the surface of the synthetic leather has the feature of not influencing the originaleffect of the leather surface, after leather surface processing and polish processing, polishing surface effect on the prudent patterns of the leather surface is good and a contrast of polishing withmatting of the groove bottom is formed, thus having unique polish effect.

Description

technical field

[0001] The invention relates to an ironing and brightening surface treatment agent for synthetic leather, in particular to a water-based PU ironing and brightening surface treatment agent for synthetic leather used in the back-end 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 t...
