Description

A kind of fire protection flame retarding polystyrene foam

Technical field

The present invention relates to a kind of foam, particularly a kind of fire protection flame retarding polystyrene foam.

Background technology

Foamed polystyrene resin is a kind of foam materials with outstanding low density and heat-insulating property of first being invented by BASF Aktiengesellschaft early 1940s.The purposes of foamed polystyrene resin is very extensive, because it has high strength, light, splendid insulation heat-insulating property and the high energy ability that absorbs of quality, can be used 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 be widely used in the aspects such as lagging material that industry was fished for and refrigerated in the roadbed laying of road and bridge and building construction and fishery.Wherein, as a kind of good 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, can 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 conductivities, high fire retardancy, preferably adhesiveproperties and preferably self intensity.

The constructional feature of foamed polystyrene resin is that specific surface area is very large, and material internal structure is cellular, and between abscess, be bubble wall, pillar or polystyrene film, the most of volume of its material internal is occupied by air, is very easy to occur 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, during foamed polystyrene resin burning, can produce orange flame, to send cinnamic smell, and follow a large amount of black smokes, toxicity is very large.

Flame-retardant foam material, because it has light weight, the performance such as fire-retardant, is widely used in the various fp occasions that need.But existing flame-retardant foam material, its flame retardant properties is not still too desirable, cannot meet the higher occasion of some fire protection requirement, is still subject in the use some limitations.

Summary of the invention

The object of this invention is to provide the good fire protection flame retarding polystyrene foam of a kind of flame retardant properties.

In order to realize object of the present invention, the present invention passes through following scheme implementation:

A fire protection flame retarding polystyrene foam, is made by 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 1520 2.3-2.8, 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 that takes 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; Preparation method puts into calcining furnace by attapulgite, clay, at 560-600 ℃, calcines 4-5 hour, takes 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 to mix, continue to grind, to fully disperseing, then add other remaining component, continue to grind after 30-45 minute, under 1500-1800 rev/min, stir 15-30 minute, obtain modified filler.

Fire protection flame retarding polystyrene foam of the present invention, is prepared from by following concrete steps:

(1) by other each mixing of materials except modified filler, Cellmic C 121, be warming up to 100-120 ℃, mixing 8-12 minute;

(2) material mixing is added modified filler, Cellmic C 121 carry out the mixing 6-10 minute of secondary at 90-100 ℃;

(3) material secondary being mixed hacks, slice, sends in molding device and carries out premolding, and forming pressure is 4-6MPa, and 15-20 takes out after second;

(4) sheet stock is added in the mould of preheating, on vulcanizing press, at 140-160 ℃ of temperature, is forced into 6-7MPa, 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 retardant effect, meet naked light and do not burn, also give polystyrene foamed material good mechanical property, intensity is high, density is little, and has kept the advantages such as insulation, light weight, the water-intake rate of polystyrene foamed material be low simultaneously.
