Abstract
A kind of preparation method of XPS, comprises the following steps：1) after including that the raw material of polystyrene, the first fire retardant, insulation agent and filler mixes, extruded in the presence of pentane, obtain expandable polystyrene particle；2) expandable polystyrene particle foaming rear mold is pressed into polystyrene moulded board；3) vacuum impregnation treatment is carried out to the polystyrene moulded board with maceration extract, and is dried, obtain the XPS；Wherein, the maceration extract includes the second fire retardant, binding agent and solvent, and alternatively includes fire retarding synergist.By the XPS prepared using the above method, excellent heat insulating effect was both can guarantee that, A grades of fire-retardant rank can have been reached again.
Description
Technical field
The present invention relates to heat-insulating construction material field, and in particular to a kind of preparation method of XPS.
Background technology
Expandable polystyrene plate, i.e. EPS (Expanded Polystyrene) plate, is by including containing physical blowing
The heated pre- hair of granules of polystyrene of agent, expansion and through curing after, the polyphenyl second of hot briquetting shape for needed in a mold
Alkene foams.
The expandable polystyrene cystosepiment that is made of foaming is being built due to excellent lasting heat insulation property
Build, the field of thermal insulation such as freezer, refrigerator car is widely used.Using the external wall outer insulation of polystyrol plastic foam plate material
Layer, realizes building energy conservation, improves the thermal environment quality in hot-summer and cold-winter area residential housing, while improve using energy source effect
Rate.But EPS sheet has the characteristics such as burning-point is low, calorific value is high, during it is as external-wall heat-insulation material application process, often trigger great
Fire, considers, construction material EPS sheet is gone back in addition to it need to possess good thermal and insulating performance from social benefit and building safety
The flame retardant regulation requirement of correlation need to be met.
Suspension method or extrusion molding manufacture EPS sheet can be taken at present.From the angle analysis of insulation, suspension method can not add conjunction
Appropriate infrared light reflecting material, the EPS sheet thermal conductivity factor of production is higher, and heat insulation effect is poor.From fire-retardant angle analysis, adopt
Take extrusion molding or suspension method production EPS insulation materials can not meet more harsh building thermal insulation material fire-retardant rank be A
The demand of level, can only achieve the fire-retardant rank (GB8624-2006 of B1《Classification on burning behaviour for building materials》).
The content of the invention
In view of the shortcomings of the prior art, the present invention is intended to provide a kind of preparation method of XPS, by that can send out
Property granules of polystyrene in add the first fire retardant and vacuum impregnation treatment in add the second fire retardant synergy,
A grades of fire-retardant rank of EPS insulation materials can be realized, while by adding Optimum Contents in expandable polystyrene particle
Graphite, ensure that EPS sheet has excellent heat insulating effect.
Present invention aim at a kind of preparation method of XPS is provided, comprise the following steps：
1) after including that the raw material of polystyrene, the first fire retardant, insulation agent and filler mixes, squeezed in the presence of pentane
Go out, obtain expandable polystyrene particle；
2) expandable polystyrene particle foaming rear mold is pressed into polystyrene moulded board；
3) vacuum impregnation treatment is carried out to the polystyrene moulded board with maceration extract, and is dried, obtain the polyphenyl second
Alkene plate；
Wherein, the maceration extract includes the second fire retardant, binding agent and solvent, and alternatively includes fire retarding synergist.
Present inventor it has been investigated that, add the first fire retardant and in Vaccum Permeating by granules of polystyrene
The maceration extract comprising the second fire retardant is used in stain treatment, it is possible to increase the effective content of fire-retardant composition in EPS sheet.Meanwhile, the
One fire retardant and the second fire retardant have synergy, can ensure that XPS has excellent fire resistance.Additionally, passing through
Pentane is used in expandable polystyrene, polystyrene can be made to be foamed into more than 80 times of expansion ratio and closed with fine
The polystyrene moulded board of the structure in hole；By using insulation agent in expandable polystyrene, can be effectively to infrared ray
Reflected, so as to improve the heat insulating effect of EPS sheet.
According to the present invention, in step 2) in, the expandable polystyrene particle of extrusion is sent out in advance in water vapour prefoaming machine
Foaming, is then molded and is made polystyrene moulded board again.Wherein, pre- hair temperature is 95 DEG C, and the time is 50 seconds, and water vapor pressure is
0.15MPa。
One of the invention preferred embodiment in, in the raw material for preparing the expandable polystyrene particle
In, to be counted by 100 weight portions of polystyrene, first fire retardant is 80-120 weight portions, preferably 90-110 weight portions；Institute
Pentane is stated for 3-7 weight portions, preferably 5-6 weight portions；The insulation agent is 1-10 weight portions, preferably 2-5 weight portions；It is described
Filler is 1-10 weight portions, preferably 2-8 weight portions.
It is of the invention another preferred embodiment in, first fire retardant be selected from magnesium hydroxide and/or hydrogen-oxygen
Change aluminium, second fire retardant is selected from expansible graphite.Magnesium hydroxide and/or aluminium hydroxide when being thermally decomposed by discharging knot
Heshui, absorbs substantial amounts of latent heat to reduce the surface temperature of synthetic material that it is filled in flame, with suppressing polymer
The effect decomposed and cooled down to produced fuel gas.On the other hand, expansible graphite being capable of covering material surface, guarantor
Protective material isolates heat and mass transfer, reduces thermal degradation speed, reaches isolation burning things which may cause a fire disaster, postpones or interrupt the effect of fire spread.
The present invention is by using two kinds of fire retardants of different fire retardant mechanisms, can more positively ensure the anti-flammability of XPS
Energy.Further, since two kinds of fire retardants are inorganic compound, combustion heat value is relatively low, thus is conducive to obtained EPS sheet to reach A
Level is fire-retardant.
It is of the invention another preferred embodiment in, the insulation agent be flaky graphite.
It is of the invention another preferred embodiment in, the fire retarding synergist be red phosphorus, Firebrake ZB, boron oxide and
2,3- dimethyl -2, the preferably at least one in 3- diphenyl butanes, red phosphorus and/or Firebrake ZB.
According to the present invention, by using above-mentioned fire retarding synergist, can be fire-retardant with the first fire retardant and second in burning
Agent cooperatively forms cooperative flame retardant system, further improves flame retardant effect, and does not produce noxious material.
It is of the invention another preferred embodiment in, counted by 100 weight portions of polystyrene, the fire-retardant synergistic
Agent is 5-15 weight portions, preferably 8-10 weight portions.
It is of the invention another preferred embodiment in, the porosity of polystyrene moulded board is 10-20%.If hole
