Description
Technical field
The present invention relates to a kind of foam, particularly a kind of modified polystyrene foam.
Background technology
Foamed polystyrene resin is early 1940s a kind of has outstanding low density and the foam materials of heat-insulating property by what first BASF company of Germany invented. The purposes of foamed polystyrene resin is widely, owing to it has high strength, light weight, extremely good insulation heat-insulating property and high-selenium corn energy ability, it is possible to as the wrapping material of various instrument, valuables, precision instrument, vegetable and fruit and fishery products etc.; And because its have that thermal conductivity is low, water-absorbent is little, electrical insulating property is good, sound insulation, protection against the tide and the good characteristic such as moulding process is simple, and the aspects such as the lagging material of fishing for and refrigerate industry with building construction and fishery laid by the roadbed being widely used in road and bridge. Wherein, as a kind of excellent material of construction, foamed polystyrene resin is mainly used in roofing and the body of wall of buildings, and it has very good energy-saving effect as external heat insulating composite wall; And it is applicable to house, factory, Ping Shi and pitch roofing as heat insulation house surface, it is possible to play the effects such as sound insulation, dash steam, sealing and heat insulating. As lagging material for building, several performance index of overriding concern are low thermal conductivity, high fire retardancy, good adhesiveproperties and good self-strength.
The constructional feature of foamed polystyrene resin is that specific surface area is very big, and material internal structure is cellular, and steeping is bubble wall, pillar or polystyrene film between hole, and its material internal major part volume is occupied by air, is very easy to flame spread after it catches fire. Therefore, foamed polystyrene resin goods is fire-retardant more a lot of than other ordinary resin material difficulties. And, orange flame can be produced when foamed polystyrene resin burns, send the smell of vinylbenzene, and with a large amount of black cigarette, toxicity is very big.
Flame-retardant foam material has light weight, the performance such as fire-retardant because of it, is widely used in various needing fp occasion. But existing flame-retardant foam material, its flame retardant properties is not still too desirable, cannot meet the occasion that some fire protection requirement is higher, is still subject to some limitations on using.
Summary of the invention
It is an object of the invention to provide a kind of modified polystyrene foam.
In order to realize the object of the present invention, the present invention is by following scheme implementation:
A kind of modified polystyrene foam, is made up of the raw material of following weight part: polystyrene 100, diatomite in powder 24-28, zinc oxide 3-4, aluminium hydroxide 4-5, Cellmic C 121 5-6, trioctyl trimellitate 2.5-3.0, carboxymethyl cellulose 3-5,2.4.6-tri-(dimethylamino methyl) phenol 2-3, sodium bicarbonate 2-3, vinyltriethoxysilane 1-2, modified filler 6-8;
Described modified filler is prepared by the following method: the raw material taking following weight part: attapulgite 110-120, clay 10-12, stalk ashes 50-55, alcohol ester 12 3-4, xitix 2-3, Silane coupling agent KH550 1-2, nano-carbon powder 1-2, sodium bicarbonate 2-3, tributyl citrate 2-3, Sodium Selenite 4-5, cuttlefish bone meal 5-6, dimethyl silicone oil 3-4; Attapulgite, clay are put into calcining furnace by preparation method, calcine 4-5 hour at 560-600 DEG C, take out, mix with stalk ashes, sodium bicarbonate, cuttlefish bone meal, it is ground to and obtains 300-400 order powder, then, then add Silane coupling agent KH550, nano-carbon powder mixing, continue grinding, to fully dispersion, then add other remaining component, continue grinding after 30-45 minute, under 1500-1800 rev/min, stir 15-30 minute, obtain modified filler.
Modified polystyrene foam of the present invention, is prepared from by following concrete steps:
(1) by each for other except modified filler, Cellmic C 121 mixing of materials, it is warming up to 100-120 DEG C, mixing 8-12 minute;
(2) material mixed adds modified filler, that Cellmic C 121 carries out two times at 90-100 DEG C is mixing 6-10 minute;
(3) material that two times mix is hacked, slice, send in molding device and carry out premolding, forming pressure is take out after 4-6MPa, the 15-20 second;
(4) sheet material is added in the mould of preheating, on vulcanizing press, it is forced into 6-7MPa at 140-160 DEG C of temperature, pressurize 6-12min, go Hair Fixer to steep, be cooled to normal temperature and get final product.
The polystyrene foam of the present invention has very rare excellent flame effect, also giving polystyrene foamed material excellent mechanical property, intensity is big, and density is low, light weight, maintains the advantages such as the insulation of polystyrene foamed material, light weight, water-intake rate be low simultaneously.
