本発明は粉状体或は粒状体を充填した中空状の外装体の
該中空内部の空気を扱いて真空状態にして形成する真空
断熱パネルの製造方法に関する。Detailed Description of the Invention (Technical Field of the Invention) The present invention relates to a vacuum insulation panel formed by treating the air inside the hollow of a hollow exterior body filled with powder or granules to create a vacuum state. Regarding the manufacturing method.
この種の真空断熱パネルにあっては、充填物として一般
にパーライトやゾノライト等が用いられる。しかしなが

を抜く所謂真空引き時において、それら充填物に吸着さ
れている空気が仲々抜けず、真空引きに長時間を要する
。In this type of vacuum insulation panel, pearlite, zonolite, etc. are generally used as the filler. However, since these fillings themselves have a gas adsorption property that is acidic, it is necessary to carry out so-called vacuum evacuation to remove the air inside the exterior body while filling the exterior body with powder or granular material made of perlite, zonolite, etc. Sometimes, the air adsorbed by these fillings cannot be easily released, and it takes a long time to vacuum.

残り易く、長期使用において侵入してくる気体に対する
吸着剤の吸着能力が低くなってしまう。In order to solve this problem, it is possible to use a material with low gas adsorption properties as a filler, but this would not be able to sufficiently adsorb gas molecules that naturally enter the exterior body during long-term use. The degree of vacuum gradually decreases and has a negative effect on insulation. For this reason, even if a material with low gas adsorption properties is used for the filling, an adsorbent such as activated carbon must be included in order to adsorb gas molecules that enter the exterior body and maintain a high degree of vacuum during long-term use. However, if this adsorbent was housed inside the outer package together with the filler and vacuumed, the problem of evacuation taking time would still remain, albeit to varying degrees. When vacuuming is carried out while the agent is housed together with the filler, the gas originally adsorbed by the adsorbent, such as activated carbon, which has high gas adsorption properties, tends to remain. ability will be reduced.
本発明の目的は、外装体に対する真空引き時間の短縮化
を図ることができる上、吸着剤を高い吸着能力を有した

を提供するにある。An object of the present invention is to provide a method for manufacturing a vacuum heat insulating panel that can shorten the time required for vacuuming an exterior body and can also encapsulate an adsorbent with a high adsorption capacity.

うにしたことを第２の特徴とするものである。In the present invention, a sealed bag containing an adsorbent with high gas adsorption property and which has been evacuated by treating the air inside is housed in an exterior body together with a filling, and in this state, the air inside the exterior body is evacuated to create a vacuum. The first feature is that a hole is made in the sealed bag and the inside of the sealed bag communicates with the exterior body, and at this time, a perforating member for making a hole in the sealed bag is provided. , consisting of a protective part and a needle-like part housed within the protective part, and the needle-like part is pressed from the outside of the exterior body to protrude from the protective part, thereby making a hole in the sealed bag. This is the second feature.

Such an exterior body 1 has a hollow interior in a vacuum state,
Further, the sealed bag 4 has a hole 6 formed therein by a perforating member 5, and this hole 6 allows the exterior body 1 and the sealed bag 4 to communicate with each other. As shown in FIG. 2, the perforating member 5 includes a rectangular tube-shaped protective portion 7 and a thumbtack-shaped needle integrally formed on one inner edge of the protective portion 7 via a self-hinge 8. A locking protrusion 10 is provided on the inner surface of the protective portion 7 on the side opposite to the self-hinge 8 .

第３図に示すように上下二分割形の成形冶具１１内に配
置し、適麻な圧力を加えて偏平なパネル状に成形する。First, the filling material 2 is accommodated in the exterior body 1 from the opening at one end, and the sealed bag 4 is filled with highly degassed adsorbent 3 and has a hole 6 whose inside is evacuated. The sealed bag 4 is housed with the perforating member 5 attached thereto. At this time, the needle-like portion 9 of the piercing member 5 is retained on the locking protrusion 10 and housed within the protection portion 7. Then, as shown in FIG. 3, the exterior body 1 containing the filler 2 and the sealed bag 4 is placed in a molding jig 11 that is divided into upper and lower halves, and is molded into a flat panel shape by applying appropriate pressure. .

Then, the air inside the exterior body 1 is evacuated from the opening at one end of the exterior body 1. At this time, since a material with low gas adsorption is used for the packing 2, the gas adsorbed by the packing 2 is removed relatively early, and the adsorbent 3, which has high gas adsorption, is Since it is highly deaerated and stored in the sealed bag 4 and is not evacuated, the interior of the exterior body 1 can be evacuated in a relatively short time. Now, after completing the evacuation inside the exterior body 1 as described above, the pair of heaters 13, 13 provided in the pressure-resistant container 12 are operated, and as shown in FIG. An opening at one end of the exterior body 1 is sandwiched between the openings 13 and the opening is hermetically sealed by thermocompression bonding.

In the vacuum thermal panel formed in this manner, the inside of the sealed bag 4 containing the highly degassed adsorbent 3 and the inside of the exterior body 1 are communicated through the holes 5, so that during long-term use, Even if gas molecules spontaneously enter the exterior body 1, the gas molecules can be adsorbed by the adsorbent 3 and the interior of the exterior body 1 can be maintained at a high degree of vacuum. Incidentally, the vacuum heat insulation panel formed as described above is used, for example, as a wall of a heat insulation box or a heat insulation door of a refrigerator.

度に維持できる。As explained above, in the present invention, a sealed bag containing an adsorbent with high gas adsorption property and which has been evacuated in advance by removing the air inside the bag is housed together with a filler in an outer case, and in this state, air inside the outer case is removed. The vacuum insulation panel is removed to create a vacuum state, and then a hole is made in the sealed bag to allow communication between the inside of the sealed bag and the exterior body.As a result, when the vacuum insulation panel is used, the exterior Since gases that naturally enter the body can be adsorbed by the adsorbent, materials with low gas adsorption properties can be used as the filler, and the adsorbent has been degassed in advance. Since the adsorbent is housed in a sealed bag, it is not necessary to degas the adsorbent at the same time when the exterior body is evacuated, and the time required for evacuating the exterior body can be shortened overall. Moreover, as mentioned above, the adsorbent is previously degassed and stored in a sealed bag, and the vacuuming of the exterior body is performed by punching holes in the sealed bag. It can be enclosed in the exterior body while retaining its gas adsorption ability, and during long-term use, the gas that naturally enters the exterior body can be adsorbed by this adsorbent to maintain a high degree of vacuum inside the exterior body.
