And then provide a kind of novel vacuum heat-insulating board.
To achieve the above object, the utility model uses following technical scheme：
A kind of novel vacuum heat-insulating board, it includes being used for the aluminium foil bag for vacuumizing encapsulation and the rock being placed in the aluminium foil bag
Cotton wool felt, two sides up and down of the rock wool felt are equipped with a layer paperboard or plastic foil, two layers of cardboard or institute respectively
State after plastic foil presses with the rock wool felt in the aluminium foil bag and vacuumize.
Preferably, the second Vacuumizing bag, the rock wool felt and two layers of cardboard or institute are provided with the aluminium foil bag
Plastic foil is stated to be placed in carrying out pressing in second Vacuumizing bag vacuumizing.
Preferably, second Vacuumizing bag is fine and close gastight Nylon Bag or aluminium foil bag.
Preferably, second Vacuumizing bag is fine and close gastight polybag.
Preferably, the thickness in monolayer of second Vacuumizing bag is 0.05-0.15 millimeters.
Preferably, the rock wool felt is ceramic fibre blanket or glass fibre guard glass fibre cotton or basalt blanket.
Preferably, the thickness of the rock wool felt is 5-50 millimeters.
Preferably, the thickness of the aluminium foil bag is 0.06-0.13 millimeters.
Preferably, the bag body of the aluminium foil bag is that three layers or four layers of aluminium foil are compounded to form.
Preferably, the cardboard is brown paper, and the thickness of the brown paper or the plastic foil is 0.01-3 millimeters.
The beneficial effects of the utility model：
Novel vacuum heat-insulating board of the present utility model lays a layer paperboard or modeling due to the upper and lower surface in rock wool felt
Expect film, this two layers of cardboard or plastic foil can not only strengthen the flatness after pressing vacuumizes, while can also effectively avoid rock
Hard impurity stamp bad Vacuumizing bag in cotton wool felt, and then improve the durable performance and heat-insulating property of vacuum heat-insulating plate.Due to
Cardboard or plastic foil have certain heat-insulated adiabatic function in itself, and two layers of cardboard can with being applied in combination for ceramic fibre blanket
Further enhance the adiabatic effect of this vacuum heat-insulating plate insulation.
Novel vacuum heat-insulating board of the present utility model by setting the second Vacuumizing bag in aluminium foil bag, make rock wool felt and
Two layers of cardboard or plastic foil are pressed and be encapsulated in the second Vacuumizing bag in advance forms overall thermal insulation board, after then vacuumizing again
The second Vacuumizing bag be encapsulated into aluminium foil bag and carry out secondary vacuum pumping pressing encapsulation, this design form has to be vacuumized twice
Encapsulating structure, second in aluminium foil bag vacuumizes packaging bag can reach permanent cured purpose substantially, play main insulation
Insulation effect, still there is preferable Vacuum Package effect even if damaged, gas leakage occurs for the aluminium foil bag in outside, inside it, therefore
Novel vacuum heat-insulating board service life of the present utility model can be greatly prolonged, the service life of vacuum heat-insulating plate is integrally improved
To more than 20 years.
Brief description of the drawings
In order that content of the present utility model is more likely to be clearly understood, below in conjunction with the accompanying drawings, the utility model is made
Further details of explanation, wherein：
Fig. 1 is structural representation when novel vacuum heat-insulating board of the present utility model does not vacuumize；
Fig. 2 is to sectional view after novel vacuum heat-insulating board of the present utility model vacuumizes by Fig. 1 A-A.
Reference is expressed as in figure：
1- aluminium foil bags；2- rock wool felts；3- cardboards；The Vacuumizing bags of 4- second.
Embodiment
Referring to Fig. 1-2, a kind of novel vacuum heat-insulating board, it includes aluminium foil bag 1 for vacuumizing encapsulation and is placed in described
Rock wool felt 2 in aluminium foil bag 1, the rock wool felt 2 can need to select ceramic fibre blanket or glass according to actual product
Fiber blanket or basalt blanket, two sides up and down of the rock wool felt 2 are equipped with a layer paperboard 3 (for ease of aobvious respectively
Show clear, the second Vacuumizing bag, upper strata cardboard, rock wool felt, lower layer paperboard are gradually extracted out one out of aluminium foil bag in Fig. 1
Section), or lay one layer of plastic foil respectively and also can reach design requirement, two layers of cardboard 3 is with the rock wool felt 2 described
Vacuumized after being pressed in aluminium foil bag 1.The second Vacuumizing bag 4, the rock wool felt 2 and two layers of institute are provided with the aluminium foil bag 1
Cardboard 3 (or plastic foil) is stated to be placed in carrying out pressing in second Vacuumizing bag 4 vacuumizing.Vacuum insulation of the present utility model
Plate lays a layer paperboard by the upper and lower surface in rock wool felt, and this two layers of cardboard can not only strengthen when pressing vacuumizes
Flatness, while can also effectively avoid the hard impurity in rock wool felt from stabbing bad Vacuumizing bag；Because cardboard has one in itself
Fixed heat-insulated adiabatic function, two layers of cardboard can further enhance the insulation of this vacuum heat-insulating plate with being applied in combination for rock wool felt
Adiabatic effect.And by setting the second Vacuumizing bag in aluminium foil bag, rock wool felt and two layers of cardboard is pressed and is sealed in advance
Overall thermal insulation board is formed in the second Vacuumizing bag, the second Vacuumizing bag after then vacuumizing again is encapsulated into aluminium foil bag
Secondary vacuum pumping pressing encapsulation is carried out, this set form has vacuumizes encapsulating structure twice, and second in aluminium foil bag is taken out true
Empty packaging bag can reach permanent cured purpose substantially, still have even if damaged gas leakage occurs for the aluminium foil bag in outside, inside it
There is preferable Vacuum Package effect, therefore novel vacuum heat-insulating board service life of the present utility model can be greatly prolonged, make true
The service life of empty heat-insulating shield is integrally improved to more than 20 years.
Ceramic fibre blanket is chosen as core plate heat-barrier material, compared with glass fibre guard glass fibre cotton, ceramic fibre blanket into
This is lower, and its coefficient of expansion, recovery dynamics are smaller, and the situation for avoiding bulge occurs, and ceramic fibre blanket can fit
