Abstract

The invention relates to a photochromic resin for chemical leather. The resin comprises a urethane resin, an acrylic resin, butyl acetate, dimethylbenzene, photochromic powder, castor oil and dimethyl silicone oil. The invention also relates to a preparation method of the photochromic resin for chemical leather. The inventive photochromic resin for chemical leather meets the environment protection standards of EU. The chemical leather treated by the inventive photochromic resin for chemical leather has good comprehensive effects in aspects such as hand feeling, color and luster and fine chap in shiny face.

Description

technical field [0001] The invention relates to a surface treatment agent for synthetic leather, in particular to a photochromic resin for synthetic leather used in the post-process of synthetic leather. At the same time, the invention also discloses a preparation method for the photochromic resin for synthetic leather. Background technique [0002] When the deterioration of the environment has become an increasingly serious problem in society, environmental protection and environmentally friendly materials have become the subject of more and more attention. At present, the photochromic resins for synthetic leather sold on the market do not meet high environmental protection standards, causing serious environmental pollution. Moreover, the synthetic leather treated with the existing photochromic resins has poor hand feeling and poor comprehensive treatment effect. [0003] Therefore, be necessary to provide a kind of novel synthetic leather photochromic resin that overcomes ...
