Abstract
At least one or more grooves are formed in a vacuum thermal insulation material, and the insulation material is bent at the grooves and not at surrounding fillet sections adjacent to the grooves. By this, stress in a laminated film occurring at groove end sections, which are boundaries between the grooves and the surrounding fillet sections, can be reduced. This enables the area of small cracks occurring in that portion of the laminated film which is in the groove end sections to be restricted to minimum. As a result, reduction in thermal insulation performance over time can be restricted even if the vacuum thermal insulation material is bent.

At first, the part that acts on because of bending stress in the film the biglyyest be kink enforcement the laminated film of evaporation.Because its film of particle that has been evaporation has ductility,, can reduce the size of crackle so compare with the size that on lamination metal paper tinsel and laminated film that plastic pellicle forms, forms the crackle that on metal foil, produces under the situation of darker slot part and bending.Consequently, can reduce the increase of gas, As time goes on reduce thereby can reduce thermoinsulation material to the intrusion of vacuum heat insulating material inside.If the vacuum heat insulating material of the degree of depth 6.5mm of above-mentioned slot part 16, bending angle 90 degree bending processes is carried out 30 days accelerated tests in 100 ℃ ageing oven, then with do not apply processing the adiabatic material of planar vacuum compare, the degeneration of pyroconductivity is 1.2 times.
On the other hand, same slot part 16 is formed in laminated thin face side that lamination metal paper tinsel and plastic pellicle form and as described below in the situation of interior lateral buckling slot part 16.Because the ductility of metal foil film is than evaporated film difference, so increase at the area of the small crackle that produces on the metal foil area than the small crackle that on evaporated film, produces, so compare with the adiabatic material of planar vacuum, confirm as follows: the degeneration of pyroconductivity is 1.3 times.
(mode of execution four)
The outer coated material structure of present embodiment do not use mode of execution one enforcement the PET8 of evaporation, and be to use the eva film of having implemented evaporation.
Present embodiment is as follows: have above-mentioned outside on the vacuum heat insulating material of coated material thickness of structure 11mm, the slot part of width 12mm, degree of depth 7.0mm is formed on the laminated thin face side of having implemented evaporation, in slot part 90 degree bendings.
With regard to the vacuum heat insulating material of above formation, below its action of explanation, effect.
At first, because in laminar structure, include the layer of the film that constitutes by the good EVA of tightness, so following effect is arranged.Promptly, even when forming slot part or form slot part and when bending, stress is on the laminated film of having implemented evaporation, become between the evaporation particle of evaporation face than under the usually big situation, also can As time goes on to reduce inhibition be irreducible minimum because of gas is invaded the heat-insulating property that causes.
If the vacuum heat insulating material of the degree of depth 7.0mm of above-mentioned slot part, bending angle 90 degree bending processes is carried out 30 days accelerated tests in 100 ℃ ageing oven, then with do not apply processing the adiabatic material of planar vacuum compare, the degeneration of pyroconductivity is 1.1 times.
(mode of execution five)
It is 40-80 that present embodiment makes the surface hardness of core.The operability of the core when keeping vacuum heat insulating material and making is set at irreducible minimum with the surface hardness of vacuum heat insulating material.Consequently, can reduce to utilize the press pressure when pressure forming forms slot part, the damage that will sting the external bag that causes because of the fiber core of vacuum heat insulating material inside internally suppresses to be irreducible minimum, thereby can reduce the aging of heat-insulating property.
Thereby, even 100 vacuum heat insulating materials are carried out the bending process of mode of execution three, also can in all vacuum heat insulating materials, initial pyroconductivity be maintained 25 * 10
-4Below the W/mK.
On the other hand, the vacuum heat insulating material making surface hardness 81-100, carry out having showed following result under the situation of the bending process shown in the mode of execution three: 2 initial pyroconductivity is 100 * 10 in 100 vacuum heat insulating materials
-4More than the W/mK.
And if make surface hardness little than 40, the core operability when then vacuum heat insulating material is made is poor, so the operating efficiency variation during the vacuum heat insulating material making.
In addition, surface hardness is a benchmark with JIS K6253, utilizes TECLOCK system テ Network ロ Star Network duro-meter (rubber plastic hardness tester) GS-721N type E to measure.
(mode of execution 6)
In the vacuum heat insulating material of present embodiment, the core adhesive-free does not promptly include tackiness agent.Because core does not include tackiness agent, so forming slot part by vacuum heat insulating material is pressurizeed or forming slot part on the vacuum heat insulating material and during in the slot part bending process, can suppress to pulverize the gas generation that causes because of core on slot part.That is, suppress for irreducible minimum, so can improve heat-insulating property because the gas that might cause heat-insulating property to reduce can be produced.
Thereby, even 10 vacuum heat insulating materials are carried out bending process shown in enforcement mode three, also can in all vacuum heat insulating materials, keep the initial pyroconductivity 25 * 10 before the processing
-4W/mK.
(mode of execution seven)
Present embodiment is that the tensile strength of outer coated material is the vacuum heat insulating material of 70-220N.Because making the tensile strength of outer coated material is more than the 70N,, As time goes on reduce thereby can reduce heat-insulating property so, also the damage of external bag can be suppressed be irreducible minimum even utilize pressure forming to form slot part and bending.And if tensile strength is 220N, then the core wall thickness when pressure becomes 0, also the damage of external bag can be suppressed for less even exert pressure.In addition, if having outer coated material that tensile strength surpasses 200N then cost uprise.
