Abstract
The invention discloses a kind of fire retardant polystyrene extruded plastic foam plate, its raw material composition fraction by weight includes 100 parts of polystyrene, 4~12 parts of expansible graphite, 2~6 parts of organic phosphorus flame retardant, 5~10 parts of phosphor-containing flame-proof type bimaleimide resin, 6~12 parts of foaming agent, and the particle diameter of expansible graphite is 200~800 mesh.Fire retardant polystyrene extruded plastic foam plate component of the present invention is simple, by introducing phosphor-containing flame-proof type bimaleimide resin and organic phosphorus flame retardant, reduces the usage amount of the fire retardant of chloride, bromine etc., can also improve the toughness and heat resistance of foamed board.
Description
Technical field
The present invention relates to foaming plate technical field, and in particular to a kind of fire retardant polystyrene extruded plastic foam plate.
Background technology
Insulation material forms according to its raw material, can be divided into inorganic heat insulation material and the major class of organic insulation material two.Inorganic guarantor
Adiabator thermal conductivity factor is high, unit weight is big, difficulty of construction is big, and use is less.Organic insulation material thermal conductivity factor is relatively low, unit weight is small,
Easily construction, and can mass automatic production, therefore use range is wider.Polystyrene is that one kind common are machine thermal insulating material
Material, has good heat insulation and preservation effect.Existing traditional Polystyrene heat insulation material, using extrusion process, is made with talcum powder
For nucleator, fire retardant is added, the thermal conductivity factor of above-mentioned insulation insulation material is relatively low.Fire retardant can be divided into inorganic and organic two big
Class, expansible graphite category inorganic combustion inhibitor, organic phosphorus flame retardant, chlorine-based flame retardant and bromide fire retardant category organic fire-resisting
Agent.The fire retardation of organic phosphorus flame retardant is mainly reflected in the high polymer catabolic phase of Initial Stage of Fire, because it can promote to polymerize
Thing dehydration carbonization, so as to reduce polymer because of thermal decomposition and caused by imflammable gas quantity, and the carbon-coating generated is also
Outside air and heat can be completely cut off.Chlorine-containing flame retardant mainly plays a role in the gas phase, because hydrogen chloride caused by chloride decomposition
Gas is non-flammable gases, there is dilution effect, and its proportion is larger, forms one layer of film overcast outside the carbon-coating of matrix surface, can
Completely cut off air and heat, play blanketing effect.Bromide fire retardant " blame " multiterminal in environmental issue.It is therefore desirable to prior art
In foamed polystyrene board raw material composition be improved.
The content of the invention
It is an object of the invention to overcome defect present in prior art, there is provided a kind of fire retardant polystyrene extruded plastic foam
Plate, using flame retardant resin and organic phosphorus flame retardant collective effect, improve the flame retardant effect of styrene.
To realize above-mentioned technique effect, the technical scheme is that：A kind of fire retardant polystyrene extruded plastic foam plate, it is special

2~6 parts, 5~10 parts of phosphor-containing flame-proof type bimaleimide resin, 6~12 parts of foaming agent, the particle diameter of expansible graphite is 200
~800 mesh.
Preferable technical scheme is, organic phosphorus flame retardant is selected from APP, melamine pyrophosphate, phosphorous swollen
At least one of swollen type fire retardant PNP, encapsulated red phosphorus.
Preferable technical scheme is that organic phosphorus flame retardant is the mixing of phosphorous expansion type flame retardant PNP and encapsulated red phosphorus
Thing, two percentages are 70~85% in phosphorous expansion type flame retardant PNP in organic phosphorus flame retardant.
Preferable technical scheme is that foaming agent is selected from HFC-134a, pentamethylene, a fluorine dichloroethanes and the chloroethene of difluoro one
At least one of alkane.
Preferable technical scheme is that foaming agent is that HFC-134a and pentamethylene mix, HFC-134a in foaming agent
Percentage by weight is 30~50%.
Preferable technical scheme is also to contain low molecular weight polyphenylene second in the raw material of fire retardant polystyrene extruded plastic foam plate
The weight ratio of alkene, low-molecular-weight polystyrene and expansible graphite is 1: (1.3~1.5).
The advantages of the present invention are：
Fire retardant polystyrene extruded plastic foam plate component of the present invention is simple, by introducing phosphor-containing flame-proof type BMI tree
Fat and organic phosphorus flame retardant, the usage amount of the fire retardant of chloride, bromine etc. is reduced, can also improve the toughness and heat resistance of foamed board
Energy.
