Problems solved by technology

[0004] 1. The organic solvent contained in solvent-based color-fixing varnish will cause the bottom layer of synthetic leather or artificial leather to dissolve, and the treated synthetic leather will not feel good;
[0005] 2. The organic solvent contained in solvent-based color-fixing varnish 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 color-fixing varnishes have poor comprehensive effects such as viscosity, stability, and hand touch

Abstract

The invention discloses a waterborne PU fixing gloss oil for synthetic leather and the fixing gloss oil comprises the following raw materials by weight percent: 30-40% of waterborne acrylic emulsion,10-25% of waterborne polyurethane resin, 30-40% of water, 1-3% of amino silicone oil, 0.5-1% of organic silicone flatting agent, 2-5% of organic silicone defoamer and 0.5-2% of waterborne polyurethanethickener. The waterborne PU fixing gloss oil for synthetic leather provided by the invention uses water as solvent instead of toxic solvents such as dimethyl formamide, butanone and the like and hasthe advantage of noninflammability, safety, environmental protection, cost-saving and the like. In addition, the waterborne PU fixing gloss oil has the advantage that the film-forming property is good, the binding is firm, and the coating has solvent resistance, cold resistance, hydrolysis resistance and thermal aging resistance. The finished product has the advantage that the original effect ofsurface leather can not be affected, the color dispersion and color migration can be avoided, the wear resistance and scratch resistance of surface leather can be increased and the fixing gloss oil has good hand feeling, delicate texture, good air permeability and other advantages.

Description

technical field [0001] The invention relates to a color-fixing varnish for synthetic leather, in particular to a water-based PU color-fixing varnish for synthetic leather used in the back-stage process of 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-fixing va...
