[Heat insulating structure body:It is set to be pasted on Qi Tabujian ]

Then, with reference to Fig. 2, Fig. 3 A, Fig. 3 B, Fig. 4 A and Fig. 4 B to representative an example of the heat insulating structure body of the disclosure into Row specifically describes.

As shown in Fig. 2 to Fig. 4 B, the heat insulating structure body 20 of the disclosure includes at least Vacuumed insulation panel 10 and other component 30, It is used in the environment of being exposed to -40 DEG C of low temperature below.As the heat-insulated knot used under such a low temperature environment Structure body 20, such as exemplary transportation of liquefied natural gas (LNG) in aftermentioned 2nd embodiment or the 3rd embodiment can be enumerated LNG tank ship.

LNG is usually -162 DEG C or so of cryogen, and it is internal in order to inhibit heat to enter to be retained in internal LNG tank And there is heat insulating structure body.During conveying LNG as LNG tank ship, such as surrounding or so can be enumerated, but in the meantime, it is heat-insulated The outer surface of structure is about -130 DEG C or so of temperature.In addition, it is from LNG tank that the LNG tank ship after having conveyed LNG, which is not, Interior discharge LNG and as complete empty, but LNG can be remained a part to inhibit temperature change.Thus, in the navigation of LNG tank ship In the process, the low temperature that the temperature of the outer surface of heat insulating structure body is -130 DEG C or so.

On the other hand, LNG tank ship meeting every few years are in the docked receipts full maintenance of maintenance ship.At this point, LNG tank exposes sometimes At a high temperature of more than room temperature, such as the outer surface of heat insulating structure body may be+80 DEG C or so.It is then desired to suspect LNG tank Heat insulating structure body the case where being used under -130 DEG C~+80 DEG C of temperature difference (temperature differences that 210 DEG C of Δ).

If generating big temperature difference as 210 DEG C of Δ in heat insulating structure body, will produce it is corresponding with the temperature difference compared with Big thermal stress.In addition, can suspect the ships such as LNG tank ship can for example be used after many decades for a long time.Therefore, for For heat insulating structure body, it is desirable that it can bear larger thermal stress, and want span length's phase real if even if generating such thermal stress Existing high reliability.

Then, in the heat insulating structure body of the disclosure 20, to the overcoating material 11 of the outer surface as Vacuumed insulation panel 10 At least part on surface assign larger wetability, and make other component 30 or other vacuum heat-insulations across elastic material Part 10 is adjacent with the surface for imparting wetability.Thereby, it is possible to larger thermal stress is mitigated using elastic material.In addition, because The outer surface wetability for the Vacuumed insulation panel 10 that elastic material is in close contact is larger, so can ensure in elastic material and vacuum Good close property between thermal insulation barriers 10.As a result, in the heat insulating structure body 20 for having used Vacuumed insulation panel 10, can make Reliability preferablyization of heat-proof quality.

The larger wetability of this place speech refers to " wetability for being more than the intrinsic wetability in surface of overcoating material 11 ". In addition, the surface region for the overcoating material 11 for having been assigned the surface state for showing such a larger wetability is known as " wetted surface area ".Wetted surface area is formed in the exterior face as Vacuumed insulation panel 10 in the surface of overcoating material 11 Surface, i.e. " outer surface ".

For example, Fig. 2 shows heat insulating structure body 20 in, Vacuumed insulation panel 10 is in its sealing 14 with along the outer of a side In the state of the mode bending on surface, other component 30 is attached to using the bonding agent 15 as elastic material.In other words, exist There is the bonding agent 15 as elastic material between Vacuumed insulation panel 10 and other component 30.

It herein, will not be with other using outer surface opposite with other component 30 in Vacuumed insulation panel 10 as " back side 10b " The opposite outer surface of component 30 (outer surface of back side 10b opposite sides) be used as " positive 10a ", will remove front 10a and back side 10b with Outer surface around outer is used as " side 10c ".In turn, Fig. 2 shows structure in, wetted surface area at least formed at For the outer surface of the overcoating material 11 of back side 10b.

In addition, wetted surface area can also be formed in becomes each outer surface (positive 10a and side in addition to the 10b of the back side At least either of face 10c) outer surface.In addition, wetted surface area can both be formed as throughout become back side 10b (according to Needing also can be in other outer surface) outer surface it is whole, can also only partly be formed.

As described later, as the bonding agent of elastic material 15 to back side 10b local coatings, thus can as The outer surface of back side 10b locally assigns (formation) wetted surface area.In addition, in the sealing 14 of the rearwardly sides 10b bending Outer surface it is opposite with the outer surface of other component 30 in the case of, can be in the overcoating material of the outer surface as sealing 14 11 outer surface also forms wetted surface area.

As described above, wetted surface area is to show the profit with the intrinsic wetability in surface for being more than overcoating material 11 The method of surface state as realization is not particularly limited in the region of moist surface state.For representativeness, It can enumerate and carry out surface treatment or resinous coat for being cladded with the outer surface of material 11.As specific surface treatment, such as Sided corona treatment, ozone treatment or corona treatment can be enumerated, but is not particularly limited to this.In addition, as specific tree Fat coating can enumerate polyurethane coating or silicon coating, but be not particularly limited to this.Surface treatment or resinous coat it is specific Type can suitably be selected according to type, structure and the material etc. of the sheet material (laminates etc.) as overcoating material 11 It selects.

About the evaluation method of wetted surface area, i.e. evaluation imparts the wetting intrinsic more than the surface of overcoating material 11 Property wetability method, be not particularly limited, but in the present embodiment, using specified in JIS K6768 based on wetting The determination method of reagent or a dyne technique of writing are evaluated.

Fig. 2 shows heat insulating structure body 20 in, Vacuumed insulation panel 10 is used as elastic material by overleaf 10b local coatings The bonding agent 15 of material, and then it is pasted onto the outer surface of other component 30.It is formed with wetting surface in the outer surface as back side 10b Region, so the bonding agent 15 of coating can be well maintained to the back side 10b of Vacuumed insulation panel 10.In addition, because bonding Agent 15 is applied without overleaf 10b whole faces, so the influence of the contraction derived from larger thermal stress can be mitigated well.

The specific type of bonding agent 15 as elastic material is not particularly limited, can be according to Vacuumed insulation panel 10 Each conditions such as the use condition or purposes of type or structure, the type of overcoating material 11 or structure or heat insulating structure body 20 are appropriate Ground is selected.

In the present embodiment, as bonding agent 15, as shown in Figure 3A and Figure 3B, first bonding agents 151 and second are used in combination Bonding agent 152.Locally separately overleaf 10b (is coated in difference for coating for these first bonding agents 151 and second bonding agents 152 Part).

As long as first bonding agents 151 have adhesiveness (or cementability) at normal temperatures, it is not particularly limited.In addition, the One bonding agent 151 preferably can initially play cementability (viscosity) person.As a result, when constructing heat insulating structure body 20, for Vacuumed insulation panel 10 can be pasted onto desired position by other component 30 without using positioning element etc..

As representative first bonding agents 151, hot-melt adhesive can be enumerated.Hot-melt adhesive will be solid at normal temperatures Body or semisolid are constituted as the material of liquid as main component at high temperature.Hot-melt adhesive is essentially free of molten Agent etc..It dissolves making hot-melt adhesive heat and makes to be applied on the basis of its is liquefied, and cured by cooling, Jin Erfa Wave bonding effect.Thus, it can play good cementability in room temperature and its peripheral temperature region.

Specific hot-melt adhesive is not particularly limited, for representative, ethylene vinyl acetate (EVA) can be enumerated Class bonding agent, polyamide (PA) class bonding agent, polypropylene (PP) class bonding agent or rubber bonding agent etc..Furthermore it is possible to by this A little each bonding agent proper combinations and used with requirement ratio mixing.

As long as second bonding agents 152 in a low temperature of -40 DEG C or less have higher than first bonding agents 151 adhesiveness (or Person's cementability), for representative, response type bonding agent can be enumerated.Response type bonding agent can be a liquid type (one-component Type), can also be two-liquid type (two-component type).Specific response type bonding agent is not particularly limited, and can enumerate polyurethanes Bonding agent, epoxy resin bonding agent or nylon-type bonding agent etc..

Response type bonding agent has following tendency:Elasticity modulus is low within the temperature range of high temperature (being higher than room temperature), but Elasticity modulus is got higher within the temperature range of low temperature (being less than room temperature).The material for playing adhesiveness has higher cohesiveness and bullet Property, so response type bonding agent can play good adhesiveness in a low temperature of -40 DEG C or less.In addition, hot melt is viscous Although good adhesiveness can be played near room temperature and its by connecing agent, can not be played in a low temperature of -40 DEG C or less fully Adhesiveness.

In the present embodiment, as described above, as elastic material, first bonding agents 151 and second bonding agents are used in combination 152.As a result, within the scope of the temperature near room temperature and its, the adhesiveness (or cementability) of first bonding agents 151 can be utilized real Existing good sticking state.In addition, within the scope of the temperature near -40 DEG C of low temperature below and its, the second bonding can be utilized The adhesiveness (or cementability) of agent 152 realizes good sticking state.
