Water-based PU silky waxy-feeling treatment agent for synthetic leather and its preparation method

Abstract

The invention relates to a water-based PU silky waxy-feeling treatment agent for synthetic leather and its preparation method. The treatment agent consists of water-based PU resin varnish, water-based amino-modified silicone oil, water, modified wax emulsion, silicon dioxide matting agent, organosilicon leveling agent, organosilicon defoaming agent and water-based PU thickening agent. The treatment agent realizes intercoordination and coaction of components of the treatment agent, has good film forming property and firm adhesive property, and forms coating with solvent resistance, cold resistance, hydrolysis resistance and thermal aging resistance, and synthetic leather treated via the treatment agent achieves perfect cloudy effect, unique silky hand feeling, strong real leather feeling, fine texture, air permeability and hand feeling, smoothness, water-proof property and wax feeling comprehensive effects.

Description

technical field [0001] The invention relates to a treatment agent for synthetic leather, in particular to a water-based PU silky waxy treatment agent for synthetic leather applied to the front-end process of synthetic leather. At the same time, the invention also discloses the water-based PU silky waxy treatment agent for synthetic leather. Preparation method of treatment agent. Background technique [0002] At present, the silky and waxy 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 tre...
