Reactive flame-retardant porcelainized powder and reinforced flame-retardant porcelainized organic silicon elastomer using same

The invention discloses reactive flame-retardant porcelainized powder and a reinforced flame-retardant porcelainized organic silicon elastomer using the same. The porcelainized powder is composed of 50-100 parts of fire-resistant filler, 1-50 parts of a multi-stage fluxing agent, 0-50 parts of a flame retardant, 0.5-5 parts of a silane coupling agent, 0.5-10 parts of hydrogen-containing silicone oil, 0-5 parts of vinyl silicone oil and 10-300 ppm of a platinum catalyst based on the content of platinum in the porcelainized powder. The porcelainized organic silicon elastomer is prepared from the porcelainized powder. According to the invention, surface chemical modification of the coupling agent is combined with hydrosilylation reaction, macromolecular flexible siloxane containing active hydrogen or vinyl is introduced to the surfaces of the fire-resistant filler, the multistage fluxing agent and the flame retardant, so that the compatibility and processability of the fire-resistant filler, the multistage fluxi
