Embodiment 1
[0031] (1) Weigh 8kg of bis-(phenyldimethylsiloxane)methylsilanol, 3kg of barium sulfate, 3kg of maleic anhydride grafted polypropylene and 0.5kg of di-n-butyltin dilaurate and mix them into a ball mill. Grind for 5 minutes and sieve through 200 mesh;
[0032] (2) Add 20kg of triethylene glycol dimethacrylate, 18kg of methyl isobutyl ketone, 10kg of polyacrylonitrile fiber, 2kg of propylene oxide butyl ether, and toner to the above-mentioned sieved components. 1 kg and 1.2 kg of diglycidyl ether were stirred at 110° C. for 5 minutes under nitrogen gas and kept for 1 hour to obtain a coating material for cables.
[0033] Table 1 shows the performance test results of the prepared coating materials for cables.
Embodiment 2
[0035] (1) Weigh 8kg of bis-(phenyldimethylsiloxane) methylsilanol, 3kg of barium sulfate, 3kg of maleic anhydride grafted polypropylene and 1kg of di-n-butyltin dilaurate and mix them, then add them to a ball mill and grind 5 minutes, sieve 200 mesh;
[0036] (2) Add 20kg of triethylene glycol dimethacrylate, 18kg of methyl isobutyl ketone, 10kg of polyacrylonitrile fiber, 2kg of propylene oxide butyl ether, and toner to the above-mentioned sieved components. 1 kg and 1.2 kg of diglycidyl ether were stirred at 110° C. for 5 minutes under nitrogen gas and kept for 1 hour to obtain a coating material for cables.
[0037] Table 1 shows the performance test results of the prepared coating materials for cables.
Embodiment 3
[0039] (1) Weigh 12kg of bis-(phenyldimethylsiloxane) methylsilanol, 2kg of barium sulfate, 2kg of wollastonite, 4kg of mica, 8kg of maleic anhydride grafted polypropylene and di-n-butyltin dilaurate After 1kg is mixed, add to a ball mill, grind for 10 minutes, and sieve through 400 mesh;
[0040] (2) Add 30kg of triethylene glycol dimethacrylate, 28kg of methyl isobutyl ketone, 15kg of polyacrylonitrile fiber, 5kg of propylene oxide butyl ether, and toner to the above-mentioned sieved components 1 kg and 1.2 kg of diglycidyl ether were stirred at 130° C. for 10 minutes under nitrogen gas, and kept for 2 hours to obtain a coating material for cables.
