Embodiment 1
[0018] (1) Add 25 parts of ethylene-vinyl acetate copolymer, 6 parts of nano-zinc oxide and 50 parts of ethanol to 110 parts of polyurethane, mix well and let stand for 15 minutes, then ultrasonically treat at ultrasonic frequency 40kHz and power 100W for 30min, then add 20 parts of high-resilience sponge and 8 parts of stearic acid were uniformly mixed and then microwaved at a microwave frequency of 2450 MHz and a power of 800 W for 15 minutes. After the treatment, it was naturally cooled to room temperature to obtain material I;
[0019] (2) Heat 12 parts of fly ash, 13 parts of wood powder and 10 parts of zeolite powder to 60-70 ° C and mix for 10 minutes, then add 8 parts of rice bran wax, 5 parts of pregelatinized starch and 2 parts of soda powder, and continue to keep warm Mix for 15 minutes to obtain material II;
[0020] (3) Add material II to material I while it is hot, then add 6 parts of tributyl citrate, 4 parts of azodicarbonamide, 3 parts of dicumyl peroxide, and...
