Problems solved by technology

In practice, it is difficult for PVC to obtain a good leather effect on the basis of natural luster and soft touch after surface treatment.
Moreover, the wear resistance and bending resistance are not good enough, and the anti-yellowing and hydrolysis resistance and high temperature resistance are not high.
Moreover, the processing technology is complicated and the cost is high

Abstract

The invention relates to non-yellowing anti-graffiti resin for synthetic leather as well as a preparation method of the resin. The non-yellowing anti-graffiti resin for synthetic leather consists of the following components: polyether polyurethane resin, DMF (Dimethyl Formamide), acetone, dimethyl siloxane, organic silicone oil, anti-graffiti additive, uvioresistant absorber and organosilicon leveling agent. After the application of the non-yellowing anti-graffiti resin for synthetic leather, the synthetic leather obtains the advantages as follows: bright gloss, smooth handfeel, good anti-yellowing property, excellent wear-twist resistance, and good pollution prevention property; and stains caused by shoe polish, lipstick paste, marking pen liquid, ball pen liquid, coffee and the like accidentally falling on the leather surface can be easily wiped off by a piece of cloth.

Description

technical field [0001] The invention relates to a resin for synthetic leather, in particular to a water-kneading pressure-change resin applied to the front-end veneer of the synthetic leather. At the same time, the invention also discloses a preparation method of the non-yellowing and anti-graffiti resin for the synthetic leather. Background technique [0002] Synthetic leather is usually divided into PU leather (polyurethane leather) and PVC leather (polyvinyl chloride leather). For PVC leather, in order to obtain softness and brightness for different products and different requirements, PVC needs to be surface treated during the manufacturing process. In practice, after surface treatment of PVC, it is difficult to obtain a good leather effect on the basis of natural luster and soft touch. Moreover, the wear resistance and bending resistance are not good enough, and the anti-yellowing and hydrolysis resistance and high temperature resistance are not high. Moreover, the pr...
