Description
Technical field
The present invention relates to a kind of foam, particularly a kind of Fireproof flame retardant polystyrene foam.
Background technology
Foamed polystyrene resin is early 1940s first invented by BASF Aktiengesellschaft a kind of there is outstanding low density and the foam materials of heat-insulating property.The purposes of foamed polystyrene resin widely, because it has light, the splendid insulation heat-insulating property of high strength, quality and high-selenium corn energy ability, the wrapping material of various instrument, valuables, precision instrument, vegetable and fruit and fishery products etc. can be used as; 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 be widely used in the roadbed laying of road and bridge and building construction and fishery and fish for and refrigerate the aspects such as the lagging material of industry.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 be applicable to house, factory, flat and pitch roofing as heat insulation house surface, the effects such as sound insulation, dash steam, sealing and heat insulating can be played.As lagging material for building, several performance index of overriding concern are low thermal conductivities, high fire retardancy, good adhesiveproperties and good self-strength.
The constructional feature of foamed polystyrene resin is that specific surface area is very large, and material internal structure is cellular, and be bubble wall, pillar or polystyrene film between abscess, its material internal major part volume is occupied by air, is very easy to flame spread occurs after it catches fire.Therefore, foamed polystyrene resin goods is fire-retardant more a lot of than other ordinary resin material difficulties.And, can orange flame be produced during foamed polystyrene resin burning, send cinnamic smell, and with a large amount of black smoke, toxicity is very large.
Flame-retardant foam material has light weight, the performance such as fire-retardant because of it, and being widely used in variously needs 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, and use is still subject to some limitations.
Summary of the invention
The object of this invention is to provide the good Fireproof flame retardant polystyrene foam of a kind of flame retardant properties.
In order to realize object of the present invention, the present invention is by following scheme implementation:
A kind of Fireproof flame retardant polystyrene foam, is made up of the raw material of following weight part: polystyrene 100, waste or used plastics 30-40, Tai-Ace S 150 12-15, aluminium sesquioxide 4-5, Paris white 20-26, Cellmic C 121 6-8, bisphenol A polycarbonate 2.5-3.0, oxidation inhibitor 15202.3-2.8, glycerol 1.2-1.5, epoxy Toenol 1140 5-6, polyvinylpyrrolidone 2-4, urea 2-3, zinc oxide 2-3, magnesium oxide 3-4, 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, at 560-600 DEG C, calcine 4-5 hour, take out, mix with stalk ashes, sodium bicarbonate, cuttlefish bone meal, be ground to and obtain 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.
Fireproof flame retardant 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, 100-120 DEG C is warming up to, mixing 8-12 minute;
(2) material mixed is added modified filler, Cellmic C 121 carries out the mixing 6-10 minute of secondary at 90-100 DEG C;
(3) material that secondary mixes is hacked, slice, send in molding device and carry out premolding, forming pressure is take out after 4-6MPa, 15-20 second;
(4) be added in the mould of preheating by sheet stock, on vulcanizing press, be forced into 6-7MPa at 140-160 DEG C of temperature, pressurize 6-12min, removes foam, is cooled to normal temperature and get final product.
Polystyrene foam of the present invention has very rare excellent flame effect, meet naked light not burn, also give polystyrene foamed material excellent mechanical property, intensity is high, density is little, and maintains the advantages such as the insulation of polystyrene foamed material, light weight, water-intake rate be low simultaneously.
