Embodiment 1
[0022] The photochromic resin for synthetic leather consists of 10 parts by weight polyurethane resin, 15 parts by weight acrylic resin, 25 parts by weight butyl acetate, 25 parts by weight xylene, 3 parts by weight photochromic powder, 1 part by weight castor oil and 1 part by weight xylene Composition of base silicone oil.
[0023] The preparation method of the above-mentioned photochromic resin for synthetic leather is: mix 10 parts by weight of polyurethane resin, 3 parts by weight of photochromic powder, 25 parts by weight of butyl acetate and 25 parts by weight of xylene, and stir evenly; add 15 parts by weight to the resulting mixture. The weight part of acrylic resin is stirred evenly; 1 weight part of simethicone and 1 weight part of castor oil are added to the obtained mixture, stirred evenly, and filtered to obtain the photochromic resin for synthetic leather of the present invention. The performance indexes of the obtained photochromic resin for synthetic leather a...
