The expansion type flame-retardant rubber sheet is used for repairing the open pore defect, so that the system meets the fireproof requirement.
At present, the fire-proof grade of a wall is damaged, and the wall is not repaired, so that the conventional product is fragile in whole after encountering fire and is easy to damage due to combustion impact. This technique is because of supply socket and switch or other cause the fire wall body structure to destroy and resume fire prevention level, and volume inflation and formation protective screen can effectively reduce smog and flame and pass through simultaneously after being heated, can be up to about 2 hours, have striven for the time for the rescue of conflagration.
The flame-retardant silicone rubber technology is not short of published information, for example, CN109401332A relates to a high-temperature vulcanized silicone rubber, platinum is adopted to catalyze hydrosilylation vulcanization, and flame retardance is a non-expansion system. CN101787846B discloses a flame-retardant high-temperature vulcanized silicone rubber strip for building doors and windows and a preparation method thereof, wherein the flame retardant is Al (OH)3 non-intumescent. The above are all non-expansion type technologies.

CN104804440B relates to an isocyanate modified vermiculite/silicone rubber composite material. CN106118065B relates to an intumescent flame retardant for flame-retardant silicone rubber, which is composed of ammonium polyphosphate, tetra [ beta- (3, 5-di-tert-butyl-4-hydroxyphenyl) propionic acid ] pentaerythritol ester and melamine-polyimide supermolecule reticular composite material. CN107759864A discloses a vulcanized doped silicone rubber of silicone rubber/styrene-butadiene rubber/expanded vermiculite. CN107880562A discloses an intumescent flame-retardant silicone rubber composite material and a preparation method thereof, wherein the intumescent flame-retardant silicone rubber composite material comprises 100 parts of methyl vinyl silicone rubber crude rubber, 20-30 parts of reinforcing filler, 0-20 parts of expandable graphite, 0-20 parts of phosphate flame retardant, 2-4 parts of vulcanizing agent and 4-6 parts of silicone oil. All the above are vulcanization systems.
The flame-retardant silicone rubber in the market is a non-expansion type technology or a vulcanization system, and is lack of expansion type environment-friendly flame-retardant non-vulcanized silicone rubber.
Therefore, the invention provides the expansion type environment-friendly flame-retardant non-vulcanized silicone rubber which is a non-drying sheet sealing material taking polydimethylsiloxane as a main material, has good adhesion, acid and alkali resistance, aging resistance, water resistance, flame retardance and excellent insulating property, and is a fireproof and sound-insulating material suitable for fireproof requirements of power sockets, switch box bodies and the like.
