Problems solved by technology

[0002] At present, most of the oily skin treatment agents for synthetic leather sold on the market are organic solvent-based, and the organic solvents in them will cause the bottom layer of synthetic leather or artificial leather to dissolve, and have the disadvantages of high cost, strong smell, serious environmental pollution, and flammability and flammability. Explosion and other safety hazards
Moreover, the synthetic leather treated with organic solvent-based oil leather treatment agent has poor hand feeling, and the comprehensive treatment effect is not good.

Abstract

The invention relates to a waterborne oily leather treatment agent for synthetic leather and a preparation method of leather treatment agent. The treatment agent is prepared from the following components: modified waterborne polyurethane, water, a waterborne leveling agent and a waterborne thickening agent. The waterborne oily leather treatment agent is a novel material for later printing of the synthetic leather, and the treatment agent can enable the synthetic leather to have smooth hand feeling; the synthetic leather treated by the treatment agent has strong glossiness and crystalline effect, cannot be broken when baked at high temperature and has good surface scratching resistance.

Description

Technical field [0001] The invention relates to the field of surface treatment agents for synthetic leather, in particular to an aqueous oily skin treatment agent for synthetic leather used in the back-end process of synthetic leather. The invention also relates to a preparation method of the synthetic leather aqueous oily skin treatment agent. Background technique [0002] At present, most of the oily skin treatment agents for synthetic leather sold on the market are organic solvents. The organic solvents will cause the bottom layer of synthetic leather or artificial leather to dissolve, and have the disadvantages of high cost, high odor, and serious environmental pollution. Potential safety hazards such as explosion. In addition, the synthetic leather processed by the organic solvent-based oil skin treatment agent has a poor hand feeling, and the comprehensive treatment effect is not good. [0003] Therefore, it is necessary to provide a new synthetic leather water-based oily sk...
