Problems solved by technology

[0003] Organic insulation materials are widely used in building materials due to their light texture and good sound-absorbing and heat-insulating properties. However, organic materials have the disadvantage of being flammable, and they will emit a lot of toxic fumes when burned, especially extruded boards and foams. Plates, etc., will melt and deform at about 80°C. Once a fire occurs, these materials will serve as combustion aids and promote the rapid spread of the fire.

Abstract

The invention discloses a flame-retardant building thermal insulation material which comprises Portland cement, fly ash, a hydrogen peroxide solution, a foam-stabilizing coagulation-promoting emulsion, water, a tackifier, polypropylene fibers and a styrene-butadiene rubber / rubber powder composite material. The styrene-butadiene rubber / rubber powder composite material is prepared from the followingraw materials: styrene-butadiene rubber, modified rubber powder, unsaturated carboxylic acid, zinc oxide, styrene, a rubber accelerator, modified nano silicon dioxide and dicumyl peroxide. The flame-retardant building thermal insulation material has good fireproof and flame-retardant properties.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to flame-retardant building insulation materials. Background technique [0002] Building insulation materials refer to materials with high resistance to heat flow, that is, materials that prevent indoor heat from radiating from the inside to the outside. If they are combined with walls, they can save wall materials and achieve insulation effects. These materials usually have a large number of closed voids inside, so they have excellent thermal insulation effect. Building insulation materials can be divided into three categories: exterior wall insulation materials, interior wall insulation materials and roof insulation materials according to their use position, and can also be divided into three categories according to their internal components: organic materials, inorganic materials and composite materials. [0003] Organic insulation materials are widely used in buildin...
