(housing material)
The housing material 4 of against vacuum thermoinsulation material 7, the plastic lamination film that uses PET (10 μ m), aluminium foil (6 μ m), high density polyethylene (HDPE) (50 μ m) by nylon (6 μ m), AM aluminum metallization to constitute with gas barrier property.
In addition, when use polypropylene, polyvinyl alcohol, polyacrylic structure etc. do not contain the laminate film of aluminium foil the time, can suppress the reduction of the heat-insulating property that causes by heat bridge.In addition, utilize sealing packing machine with 3 limit heat-sealings in 4 limits.
(manufacture method)
Being fabricated to of Vacuum thermal insulating material 7, with core body 5 be inserted into as the bag housing material 4 in, mouthful mode of not sealing with a remaining limit is fixed, in thermostatic bath, under 105 ℃ temperature, after carrying out half a day the drying of (about 12 hours), to be used to adsorb the adsorbent 6 that sees through gas that residual gas after the vacuum packaging and the gas of emitting from core body 5 along with the time and the sealing layer by housing material 4 enter and be inserted in the film bag, (NPC company makes to utilize oak formula vacuum package machine; KT-650) vacuumize.Vacuumize the degree of vacuum that proceeds in the vacuum chamber and reach about 1～10Pa, the opening portion to film bag in such vacuum chamber seals, and obtains tabular Vacuum thermal insulating material 7.
(heat-insulating property)
Secondly, for as the embodiment 1～4 of fiber assembly 1 of the present invention and the comparative example of usefulness relatively, the influence of the thickness of fiber assembly 1 to heat-insulating property is described.
Comparative material is that the cotton shape polyester of utilization and embodiment's 1～4 fiber diameter (about 15 μ m) same diameter obtains Vacuum thermal insulating material as core body, usefulness and aforementioned identical method.
The embodiment 1～4 of made and comparative example (being Vacuum thermal insulating material) utilize thermal conductivity meter " Auto Λ HC-073 (great smart machine (strain) system of English ", the thermal conductivity when measuring high temperature and be 37.7 ℃, low temperature and be 10.0 ℃ temperature difference.In addition, mensuration is carried out after one day from vacuumizing operation.
Here, the thickness of a slice fiber assembly 1 is after 2 times of the thickness that deducts housing material 4 of the thickness from Vacuum thermal insulating material 7, divided by the value of the sheet number of lamination.In addition, fiber diameter is to utilize the mean value of measured load at 100 positions of measurement microscope.Table 1 is represented with the result of fiber diameter divided by the thickness of a slice after vacuumizing.

Fig. 5 is the correlogram of explanation according to the heat-insulating property of the Vacuum thermal insulating material of form of implementation 1 of the present invention, and transverse axis is the numerical value of the thickness of a slice fiber assembly 1 divided by fiber diameter, and the longitudinal axis is the heat-insulating property ratio.In addition, heat-insulating property is than being respectively divided by the numerical value (equaling the inverse of embodiment 1～4 thermal conductivity divided by the value of the thermal conductivity of comparative example) of embodiment 1～4 thermal conductivity with the thermal conductivity of comparative example.
As seen from Figure 5, when 18 times of the not enough fiber diameter of the thickness of fiber assembly 1, and to compare under the situation of cotton-like fiber as the comparative example of core body, heat-insulating property improves.This can think that the thickness of fiber assembly 1 is more little, fiber easy more as with the face direction of the rectangular direction of adiabatic direction on be orientated, promptly, the distance of the solid conductive heat in the Vacuum thermal insulating material 7 of adiabatic direction that can extend, so, heat-insulating property can be improved.
In addition, if the thickness of fiber assembly 1 is near 1 times of fiber diameter, and is then good more near heat-insulating property more.Thereby as can be seen, the thickness of fiber assembly 1 is 1～18 times of fiber diameter preferably.
In addition and since when fiber assembly 1 thickness fiber diameter below 8 times the time, heat-insulating property is (extremely) improve sharply, so preferably, the thickness of fiber assembly is 1～8 times of fiber diameter.
[form of implementation 2: Vacuum thermal insulating material]
Fig. 6 and Fig. 7 are the perspective views of schematically representing according to the lamination main points of the core body of the formation Vacuum thermal insulating material of form of implementation 2 of the present invention.

In Fig. 7, represent, utilize the second fiber assembly 1y (sometimes both are added up to and be called " fiber assembly 1 ") of the continuous sheet of the first fiber assembly 1x of continuous sheet of not severing and not severing, both are disposed across, with the overlapping mode of each folding of scope of each folding line of clamping, the state that lamination forms.
That is, carry out lamination, can save the trouble of severing, make core body 5 efficiently, and then make Vacuum thermal insulating material 7 by a folded fibre aggregate 1 one side.
Because employed fiber assembly 1 is to make with above-mentioned manufacture method here, so organic fiber 2 is along long direction orientation.Notice this point, when fiber assembly 1 ground intersected with each other lamination, approach a contact, can further improve heat-insulating property.
[form of implementation 3: refrigerator]
Fig. 8 is the diagram of explanation according to the insulated cabinet of form of implementation 3 of the present invention, is the elevational cross-sectional view of schematically representing refrigerator.In addition, to giving identical label, the clipped explanation with form of implementation 1,2 identical parts.
In Fig. 8, refrigerator 100 comprises: outer container 9, be configured in the interior case 10 of the inside of outer container 9, and be configured in Vacuum thermal insulating material 7 and polyurethane foam 11 in the gap of outer container 9 and interior case 10, inwardly the refrigeration unit (not shown) of coolings in the case 10.In addition, outer container 9 and interior case 10 form opening portion respectively on common face, be provided with shutter door (all not shown among the figure) at this opening portion.
At this moment, because the housing material 4 of Vacuum thermal insulating material 7 contains aluminium foil, so, the danger of the heat of producing by the heat bridge of this aluminium foil wraparound is arranged.Therefore, in order to suppress the influence of this heat bridge, Vacuum thermal insulating material 7 utilizes the spacer element 8 as resin forming product, separates the configuration of turning up the soil with the coated steel plate of outer container 9.In addition, for spacer element 8, for residual clearance not in the polyurethane foam in being injected into adiabatic wall in subsequent handling, suitably configuration does not hinder the hole of the usefulness that flows.
That is, refrigerator 100 comprises: Vacuum thermal insulating material 7, the adiabatic wall 12 that is formed by spacer element 8 and polyurethane foam 11.In addition, not having specific restriction for the scope that disposes adiabatic wall 12, can be formed in the gamut in the gap between outer container 9 and the interior case 10, also can be a part wherein, in addition, also can be configured in the inside of aforementioned shutter door.
Refrigerator 100 under situation about not re-using, according to household electrical appliances recycling method, disintegrates at the recycling center of various places, recycling.At this moment, refrigerator 100 of the present invention, owing to have the Vacuum thermal insulating material 7 that disposes the core body 5 that constitutes by fiber assembly 1 (forming) by organic fiber 2, so, can not unload Vacuum thermal insulating material 7 and just carry out breaking process, when carrying out hot recycling, can not reduce combustion efficiency, can not become residue, recycling is good.
On the other hand, in disposing the refrigerator of Vacuum thermal insulating material, be under the situation of vacuum heat-insulating plate of inorganic powder at the core body of this Vacuum thermal insulating material, because powder can disperse, so, the casing former state can not be carried out breaking process, the very big trouble of the expense of having to unloads Vacuum thermal insulating material from the casing of refrigerator.
In addition, be under the situation of vacuum heat-insulating plate of glass fibre at core body, although casing former state ground can be carried out breaking process, but the glass fibre after the fragmentation mixes in the ground product of polyurethane foam, with the heat supply recycling, but, at this moment, exist combustion efficiency is reduced, perhaps can become the difficult point of the recyclings such as residue after the burning.
In addition, above, as insulated cabinet, enumerated the example of refrigerator, still, the present invention is not limited thereto, also can be refrigeration, heating equipment or warm equipment such as HEATING BOX, vehicle air conditioner, hot water supplier, and then, the case that replacement has the regulation shape, but also can be to have the outer bag of free deformation and the adiabatic bag (thermally insulated container) of inner bag.
