[0027] A1: Octaphenyl cage polysilsesquioxane modified sulfonated polyimide, prepared by the following method:
[0028] In a 100mL dry three-neck flask, add 1.6mmol 2,2'-bis(4-sulfophenoxy)biphenyldiamine, 12.5mL m-creso1 and 0.8mL triethylamine successively, and protect with nitrogen gas and Magnetic stirring; after 2,2'-bis(4-sulfonic acid phenoxy)biphenyldiamine is completely dissolved, then add 1.55mmol 3,4,9,10-perylenetetracarboxylic anhydride, 3.0mmol benzoic acid And 0.6mL isoquinoline; after stirring at room temperature for 1h, raise the temperature to 80°C for 4h, 180°C for 20h; After that, the polymer was collected by suction filtration, and dried in a vacuum oven at 60°C for 20 hours to obtain an amino-terminated sulfonated polyimide prepolymer;
[0029] 100 grams of the amino-terminated sulfonated polyimide prepolymer are first dissolved in 1000 grams of polyphosphoric acid containing 86 wt% phosphorus pentoxide, and then the amino-terminated sulfonated polyimide...
Embodiment 1
[0045] In parts by weight, add 35 parts of A1, 100 parts of B1, 6 parts of C1, 4 parts of D1, 3 parts of E1, 2 parts of F1 and 5 parts of G1 into the mixer and mix them thoroughly for 10 minutes to obtain a radiation-proof exterior wall. Real stone paint. According to the weight ratio, the real stone paint and water are mixed at a ratio of 1:0.5, and the above mixture is stirred with an electric mixer for 10 minutes. After being fully mixed, it is coated on the outer wall to complete the construction.
