Принадлежит:

The invention relates to a silicone high-density elastomer and a production method thereof, which belongs to the field of fireproofing materials. The silicone high-density elastomer comprises hydrogenpolysiloxane, monohydric polysiloxane, vinylpolysiloxane, alkylpolysiloxane, metal powder and platinum group metal catalysts, and a reinforced filler, flame retardant components, a black paint and a yellow paint can be added to prepare a dual-component silicone foam glue material. When in use, the materials are mixed in a proportion of 1:1 on site, and foamed and vulcanized on site at a normal temperature to form a high-density elastic fireproof foam. The silicone high-density elastomer does not contain toxic or harmful components, and has fireproof performance, ray penetration protection, tensibility and pressure elasticity. The silicone high-density elastomer can compensate displacement caused by vibration of mechanical pipelines and subsidence of a building, and is favorable to fire proof ...
