The embodiment 1 of the formation of expression Vacuum thermal insulating material 50 shown in Figure 1 is made of external cladding material 53, inner bag 54, core 51 and sorbent (not shown).As long as clad material 53 has gas barrier property (ガ ス バ リ ヤ), do not do being particularly limited, (Hot is molten by surface layer, vapor barrier, gas barrier layer and hot melt coating but make in embodiment 1
) the stack membrane of four layers of formation.
Particularly, the aluminium-vapour deposition layer is set on the PETG film as vapor barrier, gas barrier layer is that the aluminium-vapour deposition layer is set on ethylene vinyl alcohol copolymer film, and will be as the hygroscopicity of surface layer low polypropylene screen and the aluminium-vapour deposition layer of vapor barrier are relatively pasted.Although the hot melt coating has used the good straight chain shape low density polyethylene films of versatility, does not do being particularly limited, but can be also that the film of hot melt of high density polyethylene (HDPE) or polypropylene, polybutylene-terephthalate etc. is also passable.Here, surface layer also can use the high PA membrane of the intensity of anti-thorn or PETG film etc.
In addition, for the laminated construction of external cladding material 53, being not particularly limited in four-layer structure as long as have above-mentioned characteristic, can be also 5 layers, 3 layers.Though each layer adopts the dry laminate method to paste by means of the agent of two-package curing type ethyl carbamate binding, and Bond and method of attaching are not particularly limited in these.
For inner bag 54, though but use the polyethylene film of hot melt in embodiment 1, though used the synthetic zeolite of physisorption type for not shown sorbent, which material is not limited by this.For inner bag 54, so long as the hygroscopicity such as polypropylene screen, PETG film, polybutylene-terephthalate film are low and can hot melt, film that exhaust is few all can, for not shown sorbent, so long as hygroscopic moisture and gas, can use the physisorption type such as the different synthetic zeolite of pore diameter or silica gel, perhaps chemical reaction absorbent-types such as calcium oxide, calcium chloride, strontium oxide strontia etc.
For core 51, can be with the fiberized fiber aggregate 51a of polystyrene resin of rule structure between making, as the glass wool 51b that does not contain tackiness agent of inorfil congeries, the fiberized fiber aggregate 51c of the polystyrene resin appropriate combination of random structure is used.Particularly, in embodiment 1, as shown in Figure 5, use the fiber aggregate 51a of syndiotactic polytyrene resin and the fiber aggregate 51c of random polystyrene resin.
At this, between what is called, rule structures refers to that the stereochemistry structure has with respect to the main chain that is formed by carbon-carbon bond and alternately is positioned at rightabout D structure as the phenyl of side chain, is 110 ℃ of left and right as softening temperature, and fusing point is 270 ℃ of left and right.In addition, so-called random structure refers to usually be commonly referred to as this structure of polystyrene, stereochemistry is constructed to have and is positioned at the D structure of irregular (at random) position with respect to the main chain that is formed by carbon-carbon bond as the phenyl of side chain, and softening temperature is generally 80 ℃ of left and right.In addition, said softening temperature represents the load flexure temperature here.
Fiber aggregate 51a carries out the polystyrene resin of a rule structure fiber and changes into average diameter as the fiber aggregate of 10 μ m 290 ℃ of lower meltings and take the molten method (メ Le ト Block ロ one Application method) of blowing.Certainly can use for polystyrene resin and not use (バ one ジ Application) material, but for the polystyrene resin of random structure, also can use the recycled materials of retrieving from useless household electrical appliances and other used product.
For recycled materials, preferably use with coarse pulverization by screening, the material cleaned again fine powder be broken into the material of granular or the following degree of 5mm, but this is not particularly limited.Be not limited to this about a polystyrene resin of rule structure, also can use the polystyrene of isotactic structure.In addition, glass wool 51b having been used fiber diameter is the material of 4 μ m.In embodiment 1, as the structure of Fig. 1 (a), to clamp fiber aggregate 51c with fiber aggregate 51a and use, its usage ratio is 4: 6 (with reference to embodiment shown in Figure 5).
With the formation of these materials, after at 70～90 ℃, core 51 being carried out sufficient drying and using inner bag 54 to coat, after an end compressed and makes sealing state and insert external cladding material 53, the sealing of releasing inner bag was assembled on vacuum package machine.Then, without a break from the barometric pressure degree of vacuum 2.2Pa that reduces pressure, after keeping certain hour below degree of vacuum 2.2Pa, sealing external cladding material 53.In addition, the sealing release method of inner bag can carry out with cutter or fixture etc., there is no special appointment.When the automatic ∧ HC-074 of the measuring thermal conductivity instrument type made from the great smart machine of English society was measured the thermal conductivity of the Vacuum thermal insulating material that obtains like this, obtaining initial value was the good value of 1.9～2.1 (mW/mK).To its result of having verified the thermal conductivity after being equivalent to through 10 years under 70 ℃ of ambiances, obtain the value of 10～11 (mW/mK).Obtain through being equivalent to 10 years after heat-insulating property also than good results such as glass wool and hard urethane foams.
