[0038] A kind of preparation method of described intelligent automobile glass, comprises the following steps:
[0039] a. Melt and mix polyvinyl butyral, 2-(2'-hydroxy-5'-tert-octylphenyl) benzotriazole light stabilizer, tobermullite whiskers and extrude to obtain organic layer; the organic layer is placed between the two glass layers and thermocompressed to obtain the first laminated glass layer and the second laminated glass layer;
[0040] b. Paste a transparent graphene electric heating film on one side of the first laminated glass layer; paste a photochromic film on the upper third of one side of the second laminated glass layer, and pass through the magnetron in the lower two-thirds of the other side. MgF plating by sputtering process 2 Film, HfxTiO 2-x (x=0.1-0.15) film, Si 3 N 4 membrane;
[0041] c. Use sealant to bond the first laminated glass layer with the transparent graphene electric heating film surface, the second laminated glass layer with the photochromi...
