Abstract

The invention relates to a veneering water-kneading pressure-deformable resin for synthetic leather and a preparation method thereof. The veneering water-kneading pressure-deformable resin for synthetic leather comprises the following components: a polyurethane resin, DMF (dimethyl formamide), acetone, temperature change powder, color-changing wax powder, silica extinction powder and an organic silicon leveling agent. The synthetic leather adopting the veneering water-kneading pressure-deformable resin for synthetic leather has good extinction effect and gentle gloss; the leather surface after water kneading is soft and comfortable; and after plate pressing, a good pressure deformation effect is obtained, and the pressure deformation does not restore.

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 synthetic leather. At the same time, the invention also discloses a preparation method of the water-kneading pressure-change resin for the synthetic leather veneer. 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. Contents of the invention [0003] The object of the present invention is to provide a water kneading pressure change resin for veneer of synthetic leather. [0004] The water knead...
