Fire and explosion proof blanket and method of making same

Abstract

This application belongs to the field of fireproof materials technology and discloses a fireproof and explosion-proof blanket and its preparation method. The preparation method includes the following steps: mixing and calendering quaternary ammonium salt modified layered silicate with organosilicon rubber to obtain organoceramic silicone rubber; pressing the organoceramic silicone rubber with high-temperature resistant fiber woven fabric to obtain a silicone rubber composite tape, wherein the two sides of the silicone rubber composite tape are organoceramic silicone rubber layer and high-temperature resistant fiber woven layer, respectively; coating the surface of the inorganic ceramic material with hydrophobic silane to obtain a hydrophobic ceramic material containing a hydrophobic silane film; bonding at least two high-temperature resistant fiber woven layers of silicone rubber composite tape together to form a filling space; filling the filling space with the hydrophobic ceramic material to obtain a fireproof and explosion-proof blanket. The fireproof and explosion-proof blanket prepared by the above method can effectively prevent the inorganic material inside from getting damp and improve its fireproof performance.
