Description
Technical field
The invention belongs to building material field, especially a kind of graphite mould extruded sheet and preparation method thereof.
Background technology
The advantages such as extruded sheet is high with its intensity in recent years, heat insulation effect is excellent, coefficient rate is low, building exterior wall heat preserving market obtain a large amount of promotion and application, deeply favor by user.But its fire resistance is poor, meets the easy presence of fire of naked light, cause certain threat to personnel and property safety, and do not reach existing fire safety rules and standard in engineer applied, the extruded sheet researching and developing fire resistance higher is thus extremely urgent.
Tradition extrusion molding foam warming plate thermal conductivity is higher, selects thickness to increase; Fire resistance is poor, really can not reach the fire protection requirement of difficult combustion B1 level.Reduce product thermal conductivity, use thickness reduces, improve fire resistance and reach the above requirement of B1 level, not only energy-conservation, but also to prevent fires, Current Building ' external-wall heat-insulation material specification and requirement can be met, graphite mould extruded sheet (CXPS) of the present invention is with graphite polystyrene synthetic resins for main raw material, adds inorganic combustion inhibitor magnesium oxide, aluminum oxide and other auxiliary materials, injects CO by special process heating mixing simultaneously
2catalyzer, then continuous extrusion extrusion molding and obtained foam heat-insulating board, be called for short (CXPS).
Summary of the invention
For existing traditional extrusion molding foam warming plate Problems existing, the object of this invention is to provide a kind of graphite mould extruded sheet and effectively can overcome problems of the prior art, reduce product thermal conductivity, increase fire resistance, suppression or reduce smoke emission amount, environmental protection and energy saving.
Its technical scheme of dealing with problems is:
A kind of graphite mould extruded sheet: the graphite polystyrene synthetic resins 40-50 part having following parts by weight; Ordinary polystyrene synthetic resins 25-46 part; Magnesium oxide 5-8 part; Aluminum oxide 5-8 part; CO
2for whipping agent 8-15 part; Talcum powder 1-2 part is made.
Its preparation method is: add graphite polystyrene synthetic resins by stoichiometry, ordinary polystyrene synthetic resins, magnesium oxide, alumina fire retardant, talcum powder mix → utilize extrusion apparatus high-temperature digestion → injection CO at 180-200 DEG C completely at premixing device
2whipping agent → extrude → shaping → cooling → cutting → packaging by helical screw agitator, pressurization 13-15MPa.
The graphite mould extruded sheet performance characteristics that the present invention produces:
1, excellent heat insulation property
This product thermal conductivity is low to moderate 0.024W/m.k, the same with the thermal conductivity of polyurethane thermal insulation board, is the insulating product that inside all lagging materials, heat insulating effect is best.Its thickness selects the few 10mm of comparable traditional extruded sheet, namely selects the graphite mould extruded sheet of 40mm just can reach the heat insulation effect of 50mm tradition extruded sheet.
2, stable, preservative property
CXPS graphite mould extruded sheet main component is graphite-based, not aging in long use, do not decompose, do not produce objectionable impurities, its chemical property is extremely stable, can not cause degraded because of water suction and corrosion etc., make its degradation, still can keep its superior performance in high temperature environments.
3, fire prevention superiority
Graphite synthetic resin material have high temperature resistant, should not dissolve and burn, therefore the oxygen index of CXPS graphite plastic extrusion heated board can reach 30 (traditional extruded sheet oxygen index preferably can only reach 26), chance naked light does not burn (only contraction), discharges without dropping, smokelessly poison, and its fire resistance reaches difficult completely according to GB8624-2012 new standard and fires B
1level, and traditional B
1extruded sheet fire line is beyond one's reach.
4, the product feature of environmental protection
CXPS graphite mould extruded sheet adopts inorganic combustion inhibitor and carbonic acid gas (CO
2) foam process, its stable chemical performance, in production or construction, non-volatile objectionable impurities, harmless, be real environment protecting and power-saving material.
Two, graphite mould extruded sheet performance index and traditional product Performance comparision
