Abstract

The present invention relates to an eco-solvent soft and smooth treating agent for yangbuck leather used in a posterior section process of synthetic leather, consisting of the following components: modified polyurethane resin, butyl acetate, isopropanol, silica matting powder, modified organic silicon and polyethylene micropowder. The present invention further relates to a preparation method of the eco-solvent soft and smooth treating agent for yangbuck leather. The eco-solvent soft and smooth treating agent for yangbuck leather described in the present invention conforms to the environmental protection standard of EU; the synthetic leather treated with the treating agent has a natural luster and a soft and smooth touch sense and has an excellent comprehensive effect in hand feel, visual effect and the like. The method of the present invention is simple in process and low in production cost.

Description

technical field [0001] The present invention relates to a surface treatment agent for synthetic leather, in particular to a weak-solvent slippery treatment agent for yambuck used in the back-stage process of synthetic leather, and also relates to the preparation of the weak-solvent soft-slip treatment agent for yambuck 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 processes include printing, spraying, direct co...
