Abstract

The invention discloses an aqueous PU (Polyurethane) dry slippery feel treated agent for synthetic leather, which comprises the following raw materials in percentage by weight: 30-40 percent of aqueous PU resin, 50-60 percent of water, 1-3 percent of modified organosilicon polymer, 5-7 percent of modified amino silicone oil, 0.5-1 percent of organosilicon flatting agent, 2-5 percent of organosilicon defoaming agent and 0.5-2 percent of aqueous PU thickening agent. The aqueous PU (Polyurethane) dry slippery feel treated agent for the synthetic leather has the advantages of scientific and reasonable proportion of all the components, coordination and combined action of the components, good film forming, firm bonding, solvent resistance of a coating, cold resistance, hydrolysis resistance, heat resistance and anti-aging; and particularly, the combined action of the modified organosilicon polymer and the modified amino silicone oil ensures that the dry slippery feel of treated leather is unique, and the synthetic leather has good combined effect in the aspects of feeling, waterproofing, bonding, and the like.

Description

technical field [0001] The invention relates to a dry-slip surface treatment agent for synthetic leather, in particular to a water-based PU dry-slip surface treatment agent 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 that the existence of the base ...
