Problems solved by technology

Organic fireproof blockages are prohibited to be used in some occasions with strict environmental requirements because they contain toxic volatiles; although inorganic fireproof cement is non-toxic, it will solidify into hard blocks after the sealing is completed, without stretching and compression elasticity, and cannot be used Compensate for the mechanical displacement caused by the vibration of mechanical pipelines and the settlement of buildings, and the maintenance and replacement of wall-penetrating objects such as pipes and cables needs to be knocked out by gravity, which is very easy to damage the surrounding walls, and the maintenance of pipes and cables is very inconvenient

Abstract

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 blockage for pipeline maintenance or cable maintenance.

Description

technical field [0001] The invention belongs to the field of fireproof materials, and relates to a fireproof foam glue, specifically a silicone high-density elastic body and a production method thereof. Background technique [0002] Most of the existing fireproofing blockages use organic fireproofing materials and inorganic fireproofing cement. Organic fireproof blockages are prohibited to be used in some occasions with strict environmental requirements because they contain toxic volatiles; although inorganic fireproof cement is non-toxic, it will solidify into hard blocks after the sealing is completed, without stretching and compression elasticity, and cannot be used Compensate for the mechanical displacement caused by the vibration of mechanical pipelines and the settlement of buildings, and the maintenance and replacement of wall-penetrating objects such as pipes and cables needs to be knocked out by gravity, which is very easy to damage the surrounding walls, and the ma...
