Abstract

The invention discloses a hydraulic PU crazy horse resin for synthetic leather; the hydraulic PU crazy horse resin is constituted by the following raw materials by weight percentage: 35-45 percent of waterborne polyurethane, 30-40 percent of water, 5-8 percent of silicon dioxide color changing powder, 1-3 percent of silicone oil slip agents, 1-4 percent of extinction powder, 0.5-1 percent of organic silicon flatting agent, 2-5 percent of silicone defoaming agents, 0.5-2 percent of waterborne polyurethane thickeners and 2-5 percent of villus. The hydraulic PU crazy horse resin for synthetic leather takes water as solvent, toxic solvents such as dimethyl fomamide and butanone are replaced, therefore, the hydraulic PU crazy horse resin has non-inflammable, safe, environmental-protection, cost-saving performances, and the crazy horse resin has the advantages of good film forming property, firm adhesion, solvent-proof, cold-resistance, hydrolyzation-resistance and heat-proof ageing coating. The finished products manufactured by the crazy horse resin has the advantages of full handle, good crazy horse color-changing effect, fine and smooth texture, good air permeability and the like.

Description

technical field [0001] The invention relates to a resin for synthetic leather, in particular to a water-based PU Crazy Horse resin for synthetic leather. Background technique [0002] At present, synthetic leather products have gradually become a popular trend in the future, and synthetic leather has been widely used in the production of luggage, clothing, footwear and other products. The base fabric of PU leather is a canvas PU material with good tensile strength. In addition to being coated on the top of the base fabric, the base fabric can also be included in the middle, so that the existence of the base fabric cannot be seen from the outside. PU leather has physical properties. Good, tortuous resistance, good softness, high tensile strength, and breathability, so PU leather is widely used in footwear fabrics or weight-bearing parts of luggage. [0003] At present, the Crazy Horse resin for synthetic leather sold on the market is usually solvent-based Crazy Horse resin, ...
