Flame-retardant heat-resisting silicone rubber and preparation method thereof

[0024] The manufacture method of the flame-retardant and heat-resistant silicone rubber of the present embodiment comprises the following steps:

[0025] a. Add methyl vinyl raw rubber with a vinyl molar content of 0.12% into the kneader and stir for 2 minutes;

[0026] b. Add white carbon black, stearic acid 1801, dimethyldimethoxysilane and hydroxyl silicone oil several times, and stir thoroughly after each addition to obtain a silicone rubber compound;

[0027] c. After kneading and forming, heat up to 140°C, vacuumize, pass cooling water to cool down to 70°C, and glue out;

[0028] d. Add decabromodiphenylethane, cerium oxide, zinc oxide and vinyltrimethoxysilane in batches to the mixed silicone rubber, raise the temperature to 110°C, vacuumize, and release the glue;

[0029] e. Cool to room temperature after the glue is released to obtain the product.

[0030] After the product is made, a vulcanizing agent can be added to vulcanize during use, vulcanized at 160 degrees ...
