Abstract

The invention relates to a process for preparing a breathe-freely coating adhesive of waterborne polyurethane siloxane for cars and shoes. The invention is characterized in that the process includes that firstly producing a preformed polymer body with terminal group of -NCO by diisocyanate, hydroxymethyl silicon oil and polyester polyol, then using dimethylol propionic acid and diglycol ethylene for chain reaction, finally adding ionized water and blending after pH is adjusted to be neutral by salifying agent, and then adding silane coupling agent, removing acetone, consequently the breathe-freely coating adhesive of waterborne polyurethane siloxane for cars and shoes is obtained. The invention employs organo-silicone to graft polyurethane, and the softness and abrasive resistance for utilization are obviously improved. The coating adhesive enables leathers for cars and shoes to have relatively sound characteristics of softness, abrasive resistance, lubrication, breathe-freely property and brightness, thereby the invention can be applied to the superficial treatment of cars and shoes and the like products.

Description

technical field [0001] The invention relates to a preparation method of water-based polyurethane siloxane breathable coating glue for automobiles and shoes, which is mainly used for surface treatment of automobiles and footwear products. It belongs to the technical field of chemical additives. Background technique [0002] Most of the coating adhesives commonly used on automobile and shoe leather are solvent-based products, which are not environmentally friendly. Generally, water-based coating adhesives are water-based acrylic or polyurethane products, which are environmentally friendly, but their brightness and softness are not good. Wear-resistant. Contents of the invention [0003] The purpose of the present invention is to overcome above-mentioned deficiency, provide a kind of can not only obviously improve the softness and abrasion resistance of use, but also the preparation method of environment-friendly automobile, shoes waterborne polyurethane siloxane breathable ...
