  • Patent number: 8329819
    Abstract: The invention discloses a fire-resistant composite comprising inorganic particles well dispersed in a polymer, oligomer or copolymer having reactive functional groups. The inorganic particles also contain reactive functional groups, originally or after surface modification, that can react with the corresponding reactive functional groups of the organic component to form organic/inorganic composite materials. When the composite material is burned or exposed to fire, the organic component forms a char layer and the inorganic particles radiate absorbed heat. The inorganic particles also strengthen the mechanical properties of the structure through the reaction between inorganic and organic materials. The invention also discloses a fire-resistant plate containing the organic/inorganic component.
