Water-based PU wiping-coke treating agent for synthetic leather and its preparation method

Abstract

The invention relates to a water-based PU wiping-coke treating agent for synthetic leather. The treating agent consists of water-based PU resin varnish, modified PU emulsion, water, water-based silicone oil, modified polyamide wax powder, silicon dioxide matting agent, organosilicon leveling agent, organosilicon defoaming agent and water-based PU thickening agent. The invention also relates to a preparation method of the water-based PU wiping-coke treating agent for synthetic leather. The treating agent takes water as solvent to replace DMF, MEK and other toxic solvents, to achieve noninflammable, non-toxic and non-pollution characteristics, and fundamentally solve the toxic problem of solvent based resin paste for synthetic leather.

Description

technical field [0001] The invention relates to a water-based PU scorching treatment agent for synthetic leather and a preparation method thereof, in particular to a water-based PU scorching treatment agent for synthetic leather applied to the front-end process of synthetic leather and a preparation method thereof, belonging to the field of innovative environmental protection materials. Background technique [0002] At present, the scorching treatment agents for synthetic leather sold on the market are often solvent-based, which have the following disadvantages: [0003] 1. The organic solvent in the solvent-based surface treatment agent will cause the bottom layer of synthetic leather or artificial leather to dissolve, and the treated synthetic leather will not feel good; [0004] 2. Organic solvents are not only expensive, smelly, and cause serious environmental pollution, but also have safety hazards such as flammability and explosion; [0005] 3. The overall effect of t...
