Background technique
In producing and living, insulation, sound insulation are extremely important.Room, automobile, refrigerator, freezer etc. all need insulation.The energy is not only saved in insulation, also makes people's daily life more convenient comfortable.
A lot of thermal-insulating schemes propose and implement.Generally acknowledge that at present best techniques is vacuum heat-insulating plate (VIP).Its thermal conductivity can reach 0, and 003W/mK is applied on the refrigerator, can save energy 25%.But this thermal shield expensive is not popularized at home as yet.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.These two kinds of warming plates also have a common deficiency, that is, the plate inner vacuum chamber is whole the connection.Like this, if a place is damaged, global failure then; On the other hand, the sheet material shape of actual demand and size vary, and the vacuum chamber that is communicated with integral body is the needs that these two kinds of vacuum heat-insulation plates of characteristic can not satisfy actual production and life well.For overcoming this deficiency, the present invention has designed the vacuum bubbles heat-preservation sound-insulation board.
Summary of the invention
As everyone knows, the heat transfer mode has three kinds: gaseous exchange; The solid thermal conduction; Thermal radiation.When the gas molecule free path greater than or approach cavity two spans from the time, heat transfer by convection can be ignored; The solid surface of contact is more little, and its thermal conductivity is more little; As infrared reflection is returned temperature end, then thermal radiation is conducted heat and is significantly reduced.The present invention just is based on these physical principles and has designed the vacuum bubbles heat-preservation sound-insulation board.
If one is not communicated with other part, the gas pressure intensity in the airtight fully cavity is less than barometric pressure, the gas molecule mean free path is not less than this empty diameter, claims that then this cavity is vacuum bubbles.
The present invention has designed the vacuum bubbles heat-preservation sound-insulation board.The little vacuum bubbles of containing in this plate is disconnected mutually, and therefore, a place is damaged, does not influence the remaining part insulation.So just overcome the deficiency of original vacuum heat-insulation plate.Because vacuum is not propagated sound, so vacuum heat-insulation plate also can sound insulation.
Visible in sum; The vacuum bubbles heat-preservation sound-insulation board of the present invention's design is characterized in that, is distributed with airtight fully, mutual disconnected little cavity in the inside of this plate; Gas pressure intensity in the little cavity is less than barometric pressure, and the gas molecule mean free path is not less than this empty diameter.
Making this vacuum bubbles heat-preservation sound-insulation board can have multiple technologies, and the present invention proposes two kinds of schemes.
The characteristic of making first kind of technological scheme of this vacuum bubbles heat-preservation sound-insulation board is, gets A, two kinds of materials of B, and A kind Substance Properties is to be in colloidal state during normal temperature, when being warmed to T
AIn time, begin to solidify, and continues to be warmed to T
A0And constant temperature Δ t
AAfter time, solidify fully; B kind Substance Properties is, when T＜50 ℃, is particle or pulverulence, when being warmed to T
B≤T
AThe time, boiling, gasification; After A, two kinds of materials of B are mixed, pour in the template container and tight sealing; Mixture to A, two kinds of materials of B is warmed to T then
A0And constant temperature Δ t
AIn this process, through mixture being applied the volume of uniform pressure P (T) control mixture; Heat radiation at last, temperature drops to normal temperature.
A, two kinds of materials of B have multiple choices.Can according to solidifying temperature, with actual demand such as the match condition of B material, intensity, price, select different chemical formulations.When the B material seethe with excitement owing to heating, when gasifying, its volume must increase many.The volume of this increase since the A material in temperature T
A0In time, solidifies and is held, and when temperature descended back normal temperature, this volumes also no longer became original volume again.And when normal temperature, the B material is solid state powder or particle, the volume of its volume during much smaller than equivalent B material gaseous state.Vacuum bubbles in the solid-state like this A material has just formed.Just processed the vacuum bubbles heat-preservation sound-insulation board by A, two kinds of materials of B.
Here said temperature T
A, T
A0, T
BAnd constant temperature endurance Δ t
AAll different with the different choice of A, B material.But for A, the B material confirmed, T
A, T
A0, T
BAnd Δ t
AAll be well-determined.
Here pressure P (T) is the function of temperature.In different temperature, suitably select different pressure, also make that pressure evenly is crucial everywhere.Suitable pressure P (T) can make that each little vacuum bubbles is able to form and be not communicated with mutually.
The particle of B material is big more, and vacuum bubbles is big more; With respect to the A material, the B material proportion is big more, and little vacuum bubbles is many more.The particle of B material is big more, and ratio is big more, and little vacuum bubbles is communicated with more easily.Be insulation, vacuum bubbles quantity should be big as far as possible, and single vacuum bubbles should be little.
The characteristic of making second kind of technological scheme of aforementioned vacuum bubbles heat-preservation sound-insulation board is, gets A, two plates of B, and the apparent surface of two plates is identical closely; On the B plate, manufacture mutually be not communicated with, non-penetrating, opening direction all on osculating plane, average diameter is the little cavity of d; A, two plates of B are put into airtight case and vacuumized, when gas molecule mean free path λ in the case >=d, through the robot device in the case; With A, the heat seal or bonding on osculating plane of two plates of B; Stop then bleeding, put into air again, take out the AB plate.
So just processed aforesaid vacuum bubbles heat-preservation sound-insulation board.Be insulation, the quantity in little cavity should be many as much as possible.Can be known that by λ >=d the diameter d in little cavity is more little, needed degree of vacuum is low more, realizes more easily.
By the vacuum bubbles heat-preservation sound-insulation board that second kind of scheme processed, the characteristic in its medium and small cavity is after process in little cavity, in each little cavity, to be stained with adsorbent and siccative.This adsorbent can adsorb residual gas in the little cavity, and siccative can adsorb the surplus water steam, reduces the gas pressure intensity in the cavity.
Aforesaid vacuum bubbles heat-preservation sound-insulation board, the characteristic of its outer surface are to be stained with aluminium powder or aluminium film on an outer surface therein.Its effect is the infrared rays of reflection temperature end, reduces radiation thermal conduction.
Aforesaid vacuum bubbles heat-preservation sound-insulation board should be processed by the as far as possible little material of thermal conductivity.It is close airtight that these materials are not only wanted, and can not volatilize gas with temperature variation, the slit that can not occur breathing freely because of variation of temperature, the difference of expanding with heat and contract with cold.Such material finds easily.
