Embodiment 1
[0029] Example 1. Preparation of component A: 30g of methyl methacrylate, 10g of hydroxyethyl methacrylate, 10g of methacrylic acid, 8g of trimethylolpropane trimethacrylate, 15g of ABS resin, and 13g of neoprene After mixing, put it into the reaction kettle and stir for 3 hours at 20~30°C to dissolve completely and become a uniform liquid, then add 0.2g of hydroquinone, 1.5g of EDTA-Na, 3g of N,N dimethyl p-toluidine Stir for 1 hour, add 2 g of gas-phase silicon, 1.2 g of zinc dimethacrylate, stir for 30 minutes, and vacuumize for 1 hour to obtain component A;
[0030] Preparation of component B: put 30g of epoxy resin, 10g of cumene hydroperoxide, and 30g of dioctyl adipate into the reaction kettle in proportion and stir for 2 hours at 20~30°C to make it completely mixed evenly, and then add it into the gas phase 2 g of silicon and 0.2 g of naphthoquinone were stirred for 1 hour and vacuumized for 1 hour to obtain component B.
Embodiment 2
[0031] Example 2. Preparation of component A: Mix 15g of methyl methacrylate, 18g of tetrahydrofuran methacrylate, 10g of methacrylic acid, 8g of trimethylolpropane triacrylate, 15g of ABS resin, and 13g of hydroxyl-terminated liquid rubber , put into the reaction kettle and stir at 20~30°C for 3 hours to dissolve completely and become a uniform liquid, then add 0.2g of p-benzoquinone, 2g of EDTA-Na, 2g of N,N dihydroxyethyl-p-toluidine and stir for 1 hour, Add 1.2g of zinc dimethacrylate, add 3.4g of fumed silicon, stir for 30 minutes, and vacuumize for 1 hour to obtain component A;
