Abstract

The invention relates to PU (Polyurethane) yangbuck resin for leather and a production method thereof. The PU yangbuck resin for the leather is prepared from the following raw materials in parts by weight: 40 to 50 parts of yangbuck resin semi-finished product, 1 to 2 parts of polyethylene wax powder, 1 to 2 parts of PTFE (Polytetrafluoroethylene) micro-powder wax, 1 to 4 parts of silica matting powder, 4 to 6 parts of thermal-expansion plastic microsphere and 25 to 50 parts of organic solvent. The production method of the PU yangbuck resin for the leather comprises the following steps of firstly preparing the yangbuck resin semi-finished product; afterwards, adding the silica matting powder, the polyethylene wax powder, the PTFE micro-powder wax and the thermal-expansion plastic microsphere into the yangbuck resin semi-finished product, afterwards, adding the organic solvent, next, agitating until a mixture is uniformly dispersed, and finally, filtering, so as to obtain a finished product, wherein a rotational speed is 1,400r / min to 1,500r / min. The production method has the beneficial effects that the PU yangbuck resin obtained by the production method is high in wear resistance,good in color, luster and touch and approximate to a corium, and moreover, a preparation method used for the PU yangbuck resin is simple and quick and is high in practicability.

Description

technical field [0001] The invention relates to a polyurethane resin slurry for artificial leather, in particular to a PU yangbuck resin for leather and a preparation method thereof. Background technique [0002] With the improvement of living standards, people's demand for leather products is gradually increasing, but due to the small quantity and high price of genuine leather products, it cannot meet the increasing demand of people. [0003] At present, artificial leather products include luggage, clothing, shoes, etc., with a variety of surface shapes and effect styles: high-gloss high-solid, oily leather style, polished style, crazy horse discoloration, yangbuck, etc., whether it is in surface effects or In terms of feel, or the physical quality of products, they are still pursuing the effect of imitating genuine leather. [0004] Yangbuck resin has accounted for a large proportion in the leather market in recent years. It uses high temperature expansion and foaming to ...
