Abstract

The invention disclose a waterborne PU color-change resin for synthetic leather, which consists of the following raw materials in percentage by weight: 35 to 45 percent of waterborne polyurethane, 30 to 40 percent of water, 6 to 9 percent of silicon dioxide photochromic powder, 2 to 6 percent of dimming powder, 5 to 8 percent of amino silicone oil smoothing agent, 5 to 8 percent of emulsifying wax, 0.5 to 1 percent of organic silicon leveling agent, 2 to 5 percent of organic silicon defoaming agent, and 0.5 to 2 percent of waterborne polyurethane thickener. The waterborne PU color-change resin for the synthetic leather takes the water as a solvent to replace toxic solvent such as dimetbylformamide, butanone and the like, has the performances of noninflammability, safety, environmental protection and cost conservation, and has the advantages of good filming property, firm adhesion, and solvent resistance, cold resistance, hydrolysis resistance and heat-proofing aging of a coating; and a finished product prepared from the color-change resin has the advantages of comfortable feeling, good color-changed effect, better real leather quality, delicate 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 discoloration 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, resistance to twists and turns, good softness, high tensile strength, and breathability, so PU leather is widely used in the fabric of footwear or the weight-bearing parts of bags. [0003] At present, the color-changing resins for synthetic leather sold on the market are usually solvent-...
