Description
Technical field
The present invention relates to heat-insulating construction material fields, and in particular to a kind of preparation method of polystyrene board.
Background technique
Expandable polystyrene plate, i.e. EPS (Expanded Polystyrene) plate is by including containing physical blowing
The granules of polystyrene of agent it is heated it is pre- hair, expansion and after curing, in a mold hot briquetting be required shape polyphenyl second
Alkene foams.
Expandable polystyrene foam made of cystosepiment due to excellent lasting heat insulation property, thus building
It builds, the field of thermal insulation such as freezer, refrigerator car are widely used.Using the exterior 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 improving using energy source effect
Rate.But EPS sheet has the characteristics such as burning point is low, calorific value is high, as in external-wall heat-insulation material application process, often causes great
Fire considers that construction material in addition to need to have good thermal and insulating performance, is gone back with EPS sheet from social benefit and building safety
Relevant flame retardant regulation requirement need to be met.
Suspension method or extrusion molding can be taken to manufacture EPS sheet at present.From the angle analysis of heat preservation, conjunction cannot be added in suspension method
The EPS sheet thermal coefficient of suitable infrared light reflecting material, production is higher, and heat insulation effect is poor.From fire-retardant angle analysis, adopt
The fire-retardant rank that the EPS thermal insulation material for taking extrusion molding or suspension method to produce is not able to satisfy more harsh building thermal insulation material is A
The demand of grade, can only achieve the fire-retardant rank (GB8624-2006 " Classification on burning behaviour for building materials ") of B1.
Summary of the invention
In view of the deficiencies of the prior art, the present invention is intended to provide a kind of preparation method of polystyrene board, by that can send out
Property granules of polystyrene in the first fire retardant for adding and the second fire retardant added in vacuum impregnation processing synergistic effect,
It can be realized the A grade fire-retardant rank of EPS thermal insulation material, while by adding Optimum Contents in expandable polystyrene particle
Graphite can guarantee that EPS sheet has excellent heat insulating effect.
It is an object of that present invention to provide a kind of preparation methods of polystyrene board, include the following steps:

Out, expandable polystyrene particle is obtained；
2) expandable polystyrene particle foaming rear mold is pressed into polystyrene moulded board；
3) vacuum impregnation processing is carried out to the polystyrene moulded board with maceration extract, and dry, obtains the polyphenyl second
Alkene plate；
Wherein, the maceration extract includes the second fire retardant, binder and solvent, and optionally includes fire retarding synergist.
Present inventor it has been investigated that, by adding the first fire retardant in granules of polystyrene and in Vaccum Permeating
The maceration extract comprising the second fire retardant is used in stain processing, can be improved the effective content of fire-retardant composition in EPS sheet.Meanwhile the
One fire retardant and the second fire retardant have synergistic effect, can ensure that polystyrene board has excellent flame retardant property.In addition, passing through
Pentane is used in expandable polystyrene, and polystyrene can be made to be foamed into 80 times or more of expansion ratio and closed with fine
The polystyrene moulded board of the structure in hole；It, can be effectively to infrared ray by using insulation agent in expandable polystyrene
It is reflected, to improve the heat insulating effect of EPS sheet.
According to the present invention, in step 2), the expandable polystyrene particle of extrusion is sent out in advance in water vapour prefoaming machine
Foaming, is then molded again and polystyrene moulded board is made.Wherein, hair temperature is 95 DEG C in advance, and the time is 50 seconds, and water vapor pressure is
0.15MPa。
In a preferred embodiment of the invention, in the raw material for being used to prepare the expandable polystyrene particle
In, be 100 parts by weight by polystyrene in terms of, first fire retardant is 80-120 parts by weight, preferably 90-110 parts by weight；Institute
Stating pentane is 3-7 parts by weight, preferably 5-6 parts by weight；The insulation agent is 1-10 parts by weight, preferably 2-5 parts by weight；It is described

In another preferred embodiment of the invention, first fire retardant is selected from magnesium hydroxide and/or hydrogen-oxygen
Change aluminium, second fire retardant is selected from expansible graphite.Knot is released when magnesium hydroxide and/or aluminium hydroxide are by being thermally decomposed
Heshui absorbs a large amount of latent heat, to reduce the surface temperature of synthetic material that it is filled in flame, has and inhibits polymer
Decompose and carry out to generated fuel gas cooling effect.On the other hand, expansible graphite can covering material surface, protect
Heat and mass transfer is isolated in protective material, reduces thermal degradation rate, has the function that completely cut off fire source, delay or interrupts fire spread.
The present invention can more certainly ensure the anti-flammability of polystyrene board by using the fire retardant of two kinds of different fire retardant mechanisms
Energy.Further, since two kinds of fire retardants are inorganic compound, combustion heat value is lower, thus is conducive to EPS sheet obtained and reaches A
Grade is fire-retardant.
