Description
Technical field
The present invention relates to a kind of system of producing heat insulating material, relate in particular to a kind of dedicated system and application thereof of producing fire-retardant polyphenyl sheet material, belong to the system field that produces fire-retardant polyphenyl sheet material.
Background technology
Polystyrene thermal insulation plate is one of a kind of the most frequently used heat insulating material in the outer insulation of building, the conventional high-quality insulative of builing industry, heat insulating material, be widely used in the insulation on wall thermal insulating, flat concrete roof and steel work roof, the moistureproof insulation such as cryopreservation ground, airfield runway, speedway.
Polystyrene thermal insulation plate is in the world in like product, the heat insulating material that equal volume quality is the lightest, under same area, thickness measuring, show, its coefficient of thermal conductivity is minimum, it is very valuable insulation wood property, utilize it to do carrier and can be made into outstanding insulating product, but as heat insulating material, there is following serious defect in polystyrene thermal insulation plate:
1, inflammable.This is the fatal shortcoming of polystyrene thermal insulation plate, and almost running into naked light will be lighted easily.The fire incident that the many high-rise buildings of China in Recent Years are used polystyrene thermal insulation plate to cause because of large area takes place frequently, and causes huge economic loss and serious personal injury.
While 2, burning, discharge a large amount of fatal poison gas.Traditional polystyrene thermal insulation plate can produce a large amount of poison gas when burning, and the smog that moment produces can also make people suffocate, and this poison gas is fatal, directly jeopardizes resident's life security.The painful fact shows, the life casualty damage sequence that this type of fire causes is even more serious.Therefore, this material is used in developed country is limited in minimum application already.
3, the life-span is short.The aging period of polyphenyl plate is very short, and 10-20 is with regard to natural degradation, so polyphenyl plate, as architecture exterior wall insulating materials, is compared with the service life of building itself, its effective life cycle is not seriously mated with it.
Therefore, for polystyrene thermal insulation plate, as existing inflammable, the easy aging defect of skin heat insulating material, urgently need to develop and a kind ofly produce the dedicated system of fire-retardant polyphenyl sheet material and adopt this dedicated system to produce the method for fire-retardant polyphenyl sheet material.
Summary of the invention
One of object of the present invention is to provide a kind of system of producing fire-retardant polyphenyl sheet material;
Two of object of the present invention is to provide a kind of method that described system is produced fire-retardant polyphenyl sheet material of applying.
Above-mentioned purpose of the present invention is achieved through the following technical solutions:
A dedicated system of producing fire-retardant polyphenyl sheet material, comprising: hold the feed bin 1 of granular polystyrene, hold feed bin 2, mixer 10, trigger squeeze 8 and the drying plant 9 of the powder with bonding and anti-flaming function.
Wherein, the feed bin 2 that holds the feed bin 1 of granular polystyrene and hold the powder with bonding and anti-flaming function respectively by the conveying equipment 3 with function of measuring and 4 and two entrances 5 and 6 of mixer 8 be connected; The outlet 7 of one end of trigger squeeze 8 and mixer 10 is connected, and the other end of trigger squeeze 8 and drying plant 9 are connected.
The described feed bin that holds granular polystyrene 1 and the feed bin 2 that holds the powder with bonding and anti-flaming function can be the containers of various shapes, such as being infundibulate, square, rectangle, rhombus, cylindrical etc., are preferably infundibulate.
Granular polystyrene, with static, if can not effectively eliminate static when operation, will bring very large trouble to production; In order to overcome granular polystyrene, with static, be the puzzlement that production brings, the container that the feed bin 1 that holds granular polystyrene of the present invention preferably adopts antistatic material to be prepared into, described antistatic material can be antistatic poly (methyl methacrylate) plate, anti-static PVC plate (antistatic polyvinyl chloride panel), antistatic PC plate (antistatic polycarbonate plate) or antistatic PET plate (poly terephthalic acid diethylester) etc., is preferably the funnel-shaped container being prepared into by antistatic poly (methyl methacrylate) plate.
That granular polystyrene has is lightweight, density is little, volume is large, with characteristics such as static; The powder with bonding and anti-flaming function using in the present invention is mainly comprised of main components such as magnesia, magnesium sulfate and cementing agents, there is the performances such as fire-retardant, anti-aging, have the characteristics such as density is large, quality is fine and close, the consumption of powder mostly is 1/5 to 1/4 (volume ratio) of the consumption of granular polystyrene in addition; Due to above-mentioned factor, the two is difficult to mix fully in mixer, if powder can not mix with granular polystyrene fully, powder just can not wrap up granular polystyrene fully comprehensively, and fire resistance and the anti ageing property of the polyphenyl sheet material of producing just can not reach requirement; The present invention finds by a large amount of experiments, employing with centrifugal or/and the mixer of negative pressure function, can fully granular polystyrene and powder be mixed in stirring, guarantee powder by granular polystyrene fully, comprehensive parcel, guaranteed the fire-retardant and anti ageing property of polyphenyl sheet material; Therefore, in the present invention, mixer used is preferably with centrifugal or/and the mixer of negative pressure function.
Described trigger squeeze can be for pressing veneer, composite board, and Solid Door, the trigger squeeze of steel timber etc., for example, can be screw type trigger squeeze, can be also hydraulic trigger squeeze, these trigger squeezes all can be applicable to the present invention.
