It has 1-15 mm thick nonflammable polyethylene cross-linking foamed PEF plate, metallic plate and PEF plate adhered by a mixture coating layer of flame-retarding adhesive and silica sol in wt. ratio of 3-5:1 and with a thickness of 1-4 mm, and solves the problem of the existing fire-proof wall panel unable to possess concurrently both excellent fire-proofness and heat-insulation effect. Its advantages include good fire-proof property, high heat-insulation effect and simple production technique, and it has wide applications as light wt., heat insulating and fire-proof wall material.
Description
The present invention designs a kind of thermal insulation fire-proof wallboard and manufacture method thereof that has aluminium foil cellular board sandwich.
In the prior art, the thermal insulation of structural sheeting and fireproof performance still do not reach requirement simultaneously, if will guarantee that heat-insulating property is good, then fireproof performance does not reach class requirement as polyurethane, polystyrene combined wall board (flame retardant type); Desire to reach the fire-fighting grade of not burning, then adopt rock wools, gypsum composite board more, but its dust is harmful greatly, and also can't guarantee the intensity of composite plate.ZL98229674.6 discloses a kind of light composite board, uses the polystyrene foam plastics core, and its heat-insulating property is good, but anti-fire action is poor, does not reach the fire-protection rating requirement.
The object of the present invention is to provide a kind of fire prevention and heat-insulating property to hold concurrently excellent and preparation method is simple, cost is low and easy-to-install has the thermal insulation fire-proof wallboard of aluminium foil cellular board sandwich.
In order to achieve the above object, the present invention has adopted following technical scheme: design a kind of aluminium foil cellular board sandwich thermal insulation fire-proof wallboard that has, the aluminium foil cellular board and and its two sides metal sheet between to have at least one side to have a layer thickness be that 1～15 millimeter the cross-linked polyethylene foam that do not burn (is PEF, as follows), metal sheet and PEF plate are that 1～4 millimeter flame-retarding adhesive and Ludox weight ratio are 3～5: 1 mixture coating bonding by thickness.
In implementing process of the present invention, plastic foamboard uses the sheet material of fire-retardant type, and the making such as polystyrol plastic foam plate of for example do not burn cross-linked polyethylene foam (PEF), not firing can improve its fireproof performance and insulation effect simultaneously.The inventor filters out the cross-linked polyethylene foam PEF that do not burn through after the repetition test, and it has extremely excellent fireproof performance and insulation effect simultaneously, is that other plastic foamboard is incomparable.
The present invention's technical scheme preferably can be: the aluminium foil cellular board and and its two sides metal sheet between respectively to have a layer thickness be 7～10 millimeters PEF plate, the experimental data explanation: fire prevention that PEF had and heat insulating function are the keys that reaches the object of the invention, therefore, be equipped with the PEF plate on the both sides of aluminium foil cellular board, can make its fire prevention and insulation effect more remarkable, its thickness can be selected in 1～15 millimeter scope, but be preferably 7～10 millimeters, this moment, fire-protection rating reached (600 ℃ of B grades, 0.6 hour do not burn), can satisfy building, the fire prevention of boats and ships and adiabatic requirement.The PEF plate is too thin then can not to satisfy fire prevention and adiabatic requirement, but as if the too thick thickness that has then not only increased fire wall of this laminate, occupy too much space, and increased the investment of building.Table one is because of the PEF plate thickness and lays the quantity heat transfer property relatively:
Table one coefficient of heat conduction comparison sheet
| PEF thickness | The coefficient of heat conduction of PEF different-thickness | |
| ????1mm | (0.17 individual layer face) | (0.13 double-deck face) |
| ????3mm | (0.10 individual layer face) | (0.083 double-deck face) |
| ????5mm | (0.067 individual layer face) | (0.058 double-deck face) |
| ????8mm | (0.055 individual layer face) | (0.049 double-deck face) |
| ????10mm | (0.051 individual layer face) | (0.043 double-deck face) |
| ????15mm | (0.049 individual layer face) | (0.035 double-deck face) |
By table one as can be seen: two-sided layer is much lower than the single face layer coefficient of heat conduction, so better with the insulation effect of two-sided layer; In addition, generally when the coefficient of heat conduction warm ornament materials of can going bail for when 0.055W.M/K is following, so when with the individual layer face, can select the bed thickness of 8 millimeter, when with double-deck face, the bed thickness that can select 6 millimeter is more satisfactory.
The present invention's technical scheme preferably also can be: the flame-retarding adhesive and the Ludox weight ratio that are used for binding metal plate and aluminium foil cellular board coating are 4: 1, because Ludox (water glass) is the mineral-type cementing agent, glued membrane embrittlement easy fracture when its consumption is too high, if consumption is crossed the low resistant to elevated temperatures effect that do not have again, therefore, be used for the flame-retarding adhesive of binding metal plate and aluminium foil cellular board coating and Ludox weight ratio and be 4: 1 better, in the ordinary course of things the 3～5: the 1st, feasible.
The manufacture method of product of the present invention has following process: (1) is with sodium phosphate aqueous solution, sodium silicate aqueous solution, suds clean metal plate successively or with the mixture of one of aforementioned or its arbitrary proportion clean metal plate repeatedly, the water flushing, (2) use the mixture brushing glue-line of flame-retarding adhesive and Ludox then, normal temperature dries, (3) lay the PEF plate again, the cylinder roll extrusion, normal temperature place or 100～130 ℃ temperature under toasted 1～3 hour, assembling promptly gets product.The clean metal plate is in order to remove dirt, the oxide impurity on it, to be convenient to the bonding of gluing and metal sheet and PEF plate; With cylinder roll extrusion PEF plate then is in order to get rid of the air in it and to guarantee fully contacting of PEF plate and gluing and metal sheet, to guarantee adhesion strength; In general, after aforementioned process is finished, normal temperature place or 100～130 ℃ temperature under toasted 1～3 hour, aforesaid cementing agent promptly fully solidify and bonding firmly, can assemble this moment and product.In order to enhance productivity, can adopt the way of baking box heating, for example under the temperature about 120 ℃, to toast 2 hours, this moment, cementing agent neither can be full of cracks or embrittlement comparatively fast occur because of solidifying, again can be because of long work delays program standing time.
Compared with prior art, the present invention has following tangible advantage: the present invention has adopted the PEF plate, and used flame-retarding adhesive and Ludox mixture to make cementing agent, make its product have good fireproof performance and insulation effect simultaneously, its fire-protection rating can reach the B grade: 600 ℃ 0.6 hour, its heat preservation hot coefficient of conductivity can reach below the 0.055W.M/K.
Table two is and does not add the aluminium foil honeycomb sandwich board fire prevention PEF heat insulating material and that do not mix high temperature resistant silicon colloidal sol and heat-insulating property comparison sheet (detection of Hubei Province's building engineering quality supervision inspection center):
