Problems solved by technology

Although the usual halogen-free flame-retardant silicone rubber meets the requirements of low smoke and environmental protection, it needs to add a large amount of halogen-free flame retardants to meet higher flame-retardant requirements, which will inevitably lead to low mechanical properties, including tensile strength and tear resistance. Crack strength, etc., which limits its application in wire and cable, and the same is true in the LED light source industry

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.

Description

Technical field: [0001] The invention relates to the technical field of LED lamp production, in particular to a low-smoke, halogen-free, flame-retardant silicone rubber for LED lamp cables. Background technique: [0002] With the rapid development of the global economy and the enhancement of human awareness of environmental protection, the quality and performance requirements of wire and cable in various fields are also getting higher and higher. There are more and more fires caused by the aging of wires and cables. How to reduce the incidence of fire and the death rate in the event of fire, low smoke, halogen-free, flame retardant, and environmental protection have also become the development direction of the wire and cable industry. [0003] Silicone rubber is flexible, resistant to ozone, corona, flame, good insulation, high and low temperature resistance, and is a safe and reliable material for the production of wires and cables. Although the usual halogen-free flame-re...
