Abstract

The invention discloses a fireproof and flame-retardant composite polystyrene heat insulation material and a method for preparing a heat insulation board by using the material, which belongs to the technical field of the heat insulation boards. The composite heat insulation board combining an inorganic heat insulation material and an organic heat insulation material has the characteristics of fireproof property, heat insulation, flame-retardant property and low heat conductivity of the organic material, so the fireproof and flame-retardant performance of the composite heat insulation material can be improved based on unchanging the heat conductivity of the polystyrene. The method for preparing the composite heat insulation board is simple and easy to operate; each polystyrene granule is covered with a layer of a fireproof and flame-retardant material on the surface, so that each granule forms an integrated and independent unit, thereby effectively interrupting the conduction of the heat and the spread of the flame to achieve a non-combustion effect. The prepared composite polystyrene heat insulation board has the advantages of light weight, low heat conductivity, good heat insulation effect, high tensile strength, good toughness, high size stability, low moisture absorption and good flame resistance, and the combustion performance can be A2 grade (GB8624-2006).

Description

technical field [0001] The invention specifically relates to a fireproof and flame-retardant polystyrene composite thermal insulation material and a method for preparing a thermal insulation board by using the material, belonging to the technical field of thermal insulation boards. Background technique [0002] At present, the insulation materials used in the market are mainly divided into two categories: inorganic insulation materials and organic insulation materials. In summary, organic thermal insulation materials have the advantages of light weight, good thermal insulation performance, and good material processability, but they have poor fire resistance, poor stability, and are not resistant to aging. Inorganic thermal insulation materials such as perlite, diatomaceous earth, asbestos, slag wool, foam glass, etc., have certain fireproof properties, but they have high thermal conductivity, poor thermal insulation performance, and large bulk density. [0003] The existing...
