Description
Technical field: the invention belongs to environmental supplies, be specifically related to vacuum heat insulation sound-proof board.
Background technology: produce and life in, insulation, sound insulation are extremely important beyond doubt.Room, automobile, refrigerator, freezer etc. all need insulation.This not only saves the energy, also so that people live more convenient comfortable.
People design a lot of ways insulation.Generally acknowledge that at present best technology is vacuum heat-insulating plate (VIP).Its thermal conductivity factor can reach 0.003W/mK, is applied on the refrigerator, can save energy 10-25%.But this heat-insulating shield price fails to popularize at home.Another kind of vacuum heat-insulation plate has post, does not need core, and is simple in structure, cost is low, but the acquisition of high vacuum and keep difficulty to accomplish.Therefore, develop a kind of thermal conductivity factor equally very little, but less demanding, the cheap warming plate of vacuum is necessary.For this purpose, the present invention proposes a kind of new design.Because vacuum is not propagated sound, so the vacuum heat-insulation plate that can be incubated also can sound insulation.
Summary of the invention: well-known, the heat transfer mode has three kinds: gaseous exchange; The solid thermal conduction; Heat radiation.When the gas molecule free path greater than or close to cavity two spans from the time, convection heat transfer' heat-transfer by convection can be ignored; The solid contact-making surface is less, and its thermal conductivity factor is less; As infrared reflection is returned temperature end, then heat radiation is conducted heat and can significantly be reduced.The present invention just is based on these physical principles and has designed vacuum heat insulation sound-proof board.Two kinds of implementations are arranged.
If the gas pressure intensity in confined space is less than atmospheric pressure, the gas molecule mean free path is not less than two distances at a distance of nearest large apparent surface in this space, claims that then this space is vacuum chamber.A kind of have the plate of vacuum chamber to be called vacuum heat insulation sound-proof board.The constituted mode of the first vacuum heat insulation sound-proof board is as follows:
A kind of vacuum heat insulation sound-proof board, it is characterized in that, vacuum has been pumped in space by two panels and peripheral airtight besieged city thereof, between these two panels, be fixed with equably post, between two panels, the barrier film that is parallel to panel is arranged, and the gas molecule mean free path is not less than two at a distance of the distance between the nearest barrier film, and post passes and fixed these barrier films.
The constituted mode of the second vacuum heat insulation sound-proof board is as follows:
Vacuum heat insulation sound-proof board recited above is characterized in that, between two panels, have the dividing plate that is parallel to panel, post to pass and stationary barrier, be densely covered with on this dividing plate penetrate, open micropore, the gas molecule mean free path is not less than the diameter of micropore.
Between two panels a plurality of barrier films can be arranged, the distance between at least two barrier films should be not more than the gas molecule mean free path, can effectively intercept gas molecule at the convection heat transfer' heat-transfer by convection perpendicular to the panel direction.
The feature of vacuum heat insulation sound-proof board outer surface is to be coated with aluminium powder on the outer surface of one of two panels or to be bonded with the aluminium film.Its effect is reflected infrared ray, reduces radiant heat transfer.
The internal feature of vacuum heat insulation sound-proof board is to be coated with adsorbent and drier on the surface of the inner surface of two panels and barrier film and dividing plate.Effect is gas and the steam in the absorption vacuum chamber, keeps vacuum.
The effect of post is to support two panels not bent by atmospheric pressure, and fixedly is parallel to barrier film or the dividing plate of panel.The solid contact area of two panels is exactly the summation of the contact area of post and a panel, much smaller than the area of panel.Therefore, the solid thermal conductance can significantly reduce.
Post, two panels and periphery material, barrier film and dividing plate are manufactured with the as far as possible little material of thermal conductivity factor.Post, panel and periphery material also should have enough intensity and flame-retarding characteristic.As, be added with plastics, glass, metal of fire retardant etc.
Block board thickness in the second vacuum heat insulation sound-proof board vacuum chamber determines according to the character of material therefor.
To the two boards that surrounds vacuum chamber and the requirement of peripheral sealing material thereof be, they not only want close airtight, and can not vary with temperature and volatilize gas, variation that can not Yin Wendu, the difference of expanding with heat and contract with cold and the slit that occurs breathing freely.Such material easily finds.The height of vacuum chamber is determined as required.
Description of drawings: Fig. 1 is the longitudinal sectional drawing of the first vacuum heat insulation sound-proof board.Fig. 2 is the longitudinal sectional drawing of the second vacuum heat insulation sound-proof board.。
Among the figure, the 1st, panel; The 2nd, periphery; The 3rd, vacuum chamber; The 4th, post; The 5th, barrier film.The 6th, dividing plate.
The specific embodiment:
Embodiment 1: get two 1.0 * 1.0m
2, thick 0.5cm the rigid plastic sheet that is added with fire retardant.Wherein evenly be fixed with post (once finishing with mould) on a plate.These post sectional areas are 1 (mm)
2, height 1mm is each other at a distance of 1cm.At the middle part of two panels, be parallel to panel and place two barrier films at a distance of about the thickness 0.02mm of 0.05mm.Post passes and fixes this two barrier films.Two films also are fixed on the periphery of vacuum chamber.The periphery of vacuum chamber is with thickness 1cm, the material making identical with panel, and is bonded together securely with two panels are airtight.Be coated with adsorbent and drier at the inner surface of two panels and the surface of barrier film.Be coated with aluminium powder for reflected infrared ray at the outer surface of one of two panels.Then by the duct of reserving vacuum chamber is vacuumized, make the interior gas pressure intensity of vacuum chamber be not more than 1Pa.At last, seal the duct of bleeding.So just carried out a vacuum heat insulation sound-proof board.
Embodiment 2: the manufacturing way of the second vacuum heat insulation sound-proof board is identical with the key step of manufacturing the first vacuum heat insulation sound-proof board.Difference is as follows: the distance of two panels and the height of post all are 2.4mm; A dividing plate is settled at middle part at two panels; Post passes and fixes this dividing plate; Block board thickness 2mm, the material very little by thermal conductivity factor consists of, be densely covered with on it aperture in 0.01～0.1mm scope, penetrate, open duct; Gas pressure intensity is not more than 50Pa in the vacuum chamber.If the aperture is in 10～100nm scope, then gas pressure intensity is not more than 1000Pa and gets final product.The remainder method for production is identical with the first vacuum heat insulation sound-proof board.
