Water-based PU (Polyurethane) tender-skin-feel treating agent for synthetic leather and preparation method of treating agent

Abstract

The invention discloses a water-based PU (Polyurethane) tender-skin-feel treating agent for synthetic leather. The water-based PU tender-skin-feel treating agent comprises water-based PU resin gloss oil, modified wax emulsion, water, water-based amino silicon oil, silica extinction powder, an organic silicon defoamer and an organic silicon flatting agent. The water-based PU tender-skin-feel treating agent for the synthetic leather has the unique properties of noninflammability, safety and environment friendliness as taking water as a solvent, is good in film-forming property, firm in bonding, solvent-resistant in coating, resistant to cold, hydrolysis and thermal ageing, unique in tender skin hand feel, strong in leather feel, delicate in texture and good in air permeability, ensures an excellent matte effect of the treated synthetic leather, guarantees the excellent comprehensive effects of smooth hand feel, waterproof property, wax feel and the like of the synthetic leather adopting the treating agent, and does not change the conventional production process and equipment of the synthetic leather and increase the production cost of synthetic leather products.

Description

technical field [0001] The present invention relates to a surface treatment agent for synthetic leather, in particular to a water-based PU skin rejuvenation treatment agent for synthetic leather applied to the post-stage process of synthetic leather, and also relates to the preparation of the water-based PU skin rejuvenation treatment agent for synthetic leather method. Background technique [0002] As a substitute for natural leather, synthetic leather has the characteristics of convenient processing, uniform quality, and diverse varieties. It makes up for the lack of genuine leather resources and covers almost all areas where genuine leather is used. Compared with genuine leather, synthetic leather can satisfy people's more surface needs. style requirements. In the field of synthetic leather manufacturing, surface treatment is a technology that has been paid more and more attention, and it is an effective way to increase the added value of products. Surface treatment pro...

AI Technical Summary

Problems solved by technology

[0004] 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;

[0005] 2. Organic solvents not only have high cost, high odor, and serious environmental pollution, but also have safety hazards such as flammability and explosion;

[0006] 3. The overall effect of processing synthetic leather is not good
