Abstract
The invention discloses a low-smoke zero-halogen fame-retardant silicone rubber for LED-lamp-used cables and relates to the technical field of LED lamp production. The low-smoke zero-halogen fame-retardant silicone rubber is prepared from the following raw materials in parts by mass: 100-120 parts of methyl vinyl silicone rubber, 5-10 parts of nano cerium oxide, 3-5 parts of melamine pyrophosphate, 3-5 parts of pentaerythrotol, 2-4 parts of ammonium polyphosphate, 5-8 parts of vanadium, 2-5 parts of aluminum triethyl, 3 to 6 parts of diphenyl silandiol, 1-3 parts of carbon fibers, 5-10 parts of calcium stearate, 2-5 parts of potter's clay, 5-8 parts of an anti-ager VK-B04 and 3-8 parts of salicylic acid. The low-smoke zero-halogen fame-retardant silicone rubber does not contain halogen, generates extremely low-concentration smoke and toxicity during combustion, and therefore causes no harm to humans; besides, owing to the synergistic effect of all the components, excellent flame resistance and favorable mechanical strength are achieved.
