Abstract

The invention relates to a vitrifiable flame-retardant silicone rubber foam material and a preparation method thereof. The vitrifiable flame-retardant silicone rubber foam material is prepared from the following raw materials in parts by mass: 100 parts of silicone rubber, 1-10 parts of foaming agent, 1-8 parts of foaming aid, 1-5 parts of vulcanizing agent, 1-40 parts of reinforcing agent, 1-10 parts of structure controller, 1-40 parts of combustion improver, 0-20 parts of vitrification filler and 0-15 parts of vitrification aid. The silicone rubber foam material provided by the invention has the advantages of favorable flame retardancy and favorable high-temperature dimensional stability, and is vitrifiable at low temperature.

Description

technical field [0001] The invention relates to a flame-retardant silicone rubber material, in particular to a porcelain-able flame-retardant silicone rubber foam material. Background technique [0002] At present, people's awareness of environmental protection and safety is gradually increasing, and strengthening environmental protection and safety precautions has already become the consensus of mankind. Therefore, non-halogenated, low-smoke, low-toxicity, and high-efficiency are the current flame retardant research trends; secondly, when a fire occurs with traditional flame retardant materials, the mechanical properties of the material are rapidly reduced, such as using only aluminum hydroxide flame retardant, burning ashes It is powdery, completely loses its mechanical properties, and easily causes secondary damage to people's personal safety. How to improve people's escape and rescue time will be another research focus of flame-retardant materials, and porcelain-resista...
