A kind of Novel fireproof phenolic aldehyde composite board
Technical field
The utility model relates to a kind of Novel fireproof phenolic aldehyde composite board.
Background technology
In the prior art, skin heat insulating material is generally pure organic materials, although heat insulation effect reaches the relevant criterion of country, fireproof performance lower grade, easy breaking out of fire.Such as: Shanghai " 1115 " fire to ignite polyurethane foam heat insulation material because two electric welders implement electric welding fields in violation of rules and regulations; Ignite when " CCTV's big fire " is owing to setting off fireworks extruded polystyrene warming plate.
Phenolic board is made up of phenolic foam material, the laudatory title that phenol formaldehyde foam have " king of heat insulating material ", is novel heat insulation fire-proof sound insulation material.It has light weight, fire prevention, chance naked light do not burn, smokeless, nontoxic, without drippage.It, as a kind of safe, green novel energy-saving construction material, has obtained the accreditation of construction department and public security fire-fighting department personage.It is applied to large die built-in system, fireproof heat insulating system, construction wall heat preservation decoration integrative system, labeled door interlayer and sandwich panel room etc. in building heat preservation engineering.
Warming plate of the prior art is pressed in metal outer panel by phenol formaldehyde foam, but because the interval between phenol formaldehyde foam is excessive, and cause effect of heat insulation unsatisfactory.
Utility model content
The technical problems to be solved in the utility model is to provide the better insulating tube of a kind of effect of heat insulation.
For solving the problem, the utility model provides a kind of Novel fireproof phenolic aldehyde composite board, comprise, lower spaced double layer of metal plate, it is characterized in that, the two ends of two pieces of described metal sheets are all connected by the heat insulation junction plate of T-shaped, the first cavity volume is formed between described metal sheet and junction plate, phenol formaldehyde foam is filled with in described first cavity volume, described phenol formaldehyde foam is embedded with some and described metal sheet and contacts and the hollow cavity be made up of film, described hollow cavity inside comprises the first space and second space that are partitioned into by intermediate plate, described intermediate plate is paraffin matter, watery hydrochloric acid is provided with in described first space, limestone is provided with in described second space, marble, one or more of soda ash.
As further improvement of the utility model, described junction plate is made up of vertical portion and horizontal part, and upper and lower surface, described vertical portion flushes with the upper and lower surface of two described metal sheets respectively, and described horizontal part part snaps in the gap between two described metal sheets.
As further improvement of the utility model, described metal sheet and horizontal part are respectively equipped with some first through holes and the second through hole, described first through hole is communicated with described second through hole and is screwed hole, through this first through hole and the second through hole, is provided with the bolt be threaded with it.
As further improvement of the utility model, described first through hole is counterbore.
As further improvement of the utility model, the solid in described second space is soda ash.
As further improvement of the utility model, between described metal sheet and described junction plate, be provided with diaphragm seal.
The beneficial effects of the utility model are, phenol formaldehyde foam is embedded with some and described metal sheet and contacts and the hollow cavity be made up of film, after this composite plate machines, the metal sheet of composite plate is heated slightly, the intermediate layer in hollow cavity is melted, material hybrid reaction in first space and second space, produce carbon dioxide, be full of hollow lumen, make its volume expansion, and make phenol formaldehyde foam more tight, improve heat insulating effect.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further details.
As shown in Figure 1, the utility model comprises, lower spaced double layer of metal plate 2, it is characterized in that, the two ends of two pieces of described metal sheets 2 are all connected by the heat insulation junction plate 4 of T-shaped, the first cavity volume 6 is formed between described metal sheet 2 and junction plate 4, phenol formaldehyde foam 8 is filled with in described first cavity volume 6, described phenol formaldehyde foam 8 is embedded with some and described metal sheet 2 and contacts and the hollow cavity 10 be made up of film, described hollow cavity 10 inside comprises the first space 14 and second space 16 that are partitioned into by intermediate plate 12, described intermediate plate 12 is paraffin matter, watery hydrochloric acid is provided with in described first space 14, limestone is provided with in described second space 16, marble, one or more of soda ash.
Phenol formaldehyde foam 8 is embedded with some and described metal sheet 2 and contacts and the hollow cavity 10 be made up of film, after this composite plate machines, the metal sheet 2 of composite plate is heated slightly, intermediate layer in hollow cavity 10 is melted, the material hybrid reaction in the first space 14 and second space 16, produce carbon dioxide, be full of hollow lumen, make its volume expansion, and make phenol formaldehyde foam 8 more tight, improve heat insulating effect.
As further improvement of the utility model, described junction plate 4 is made up of vertical portion 18 and horizontal part 20, the upper and lower surface of upper and lower surface, described vertical portion 18 metal sheet 2 described with two respectively flushes, and described horizontal part 20 part snaps in the gap between two described metal sheets 2.
Adopt the junction plate 4 of this structure, square composite plate can be spliced to form with metal sheet 2.
As further improvement of the utility model, described metal sheet 2 and horizontal part 20 are respectively equipped with some first through hole 22 and the second through holes 24, described first through hole 22 is communicated with described second through hole 24 and is screwed hole, through this first through hole 22 and the second through hole 24, be provided with the bolt 26 be threaded with it.
Adopt the mode connection metal plate 2 and junction plate 4 that are threaded, make connection tightr.
As further improvement of the utility model, described first through hole 22 is counterbore.
This first through hole 22 is counterbore, makes composite plate keep a parallel surface.
As further improvement of the utility model, the solid in described second space 16 is soda ash.
Reaction solid is soda ash, fast with watery hydrochloric acid reaction speed.
As further improvement of the utility model, between described metal sheet 2 and described junction plate 4, be provided with diaphragm seal 28.
Be provided with diaphragm seal 28, ensure metal sheet 2 and the sealing be connected between junction plate 4.
Above-described embodiment is the utility model preferably embodiment; but embodiment of the present utility model is not by the restriction of embodiment; the change done under other any does not deviate from Spirit Essence of the present utility model and principle, modification, substitute, combine, simplify the substitute mode that all should be equivalence, be included within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should define with claim is as the criterion.
