ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for joining each layer of a multilayer insulation used as a heat insulating material in an artificial satellite or the like.

れていた。 Conventional multilayer insulation, as shown in Figure 1, consists of depositing a metal 2 on one or both sides of a plastic film 1 with poor thermal conductivity (for example, Mylar film) in order to reduce the infrared emissivity of the surface. It consists of a plurality of sheets stacked one on top of the other in multiple layers at predetermined intervals, and each layer is usually sewn together with thread 3.

性、ハンドリング性を良くする長所があつた。 In conventional multilayer insulation, the spacing between each layer and the contact area between each layer are constant due to the method of sewing each layer with thread, so the heat insulation effect of multilayer insulation can be maintained at a constant performance. was completed. Furthermore, when handling multilayer insulation, there is no misalignment between the layers, which has the advantage of improving workability and handling.

われ作業性の悪さが欠欠点であつた。 However, if a normal sewing machine is used to sew multi-layer insulation, (i) the needle hole created on the sheet surface is easy to avoid, (ii) the metal deposition on the sheet surface is damaged, and (iii) each layer of the sheet slips, so the sewing machine cannot be used. However, there are disadvantages such as difficulty in automatically feeding the sheet, and it is necessary to modify a normal sewing machine for multi-layer insulation.Generally, multi-layer insulation is sewn by hand, which results in poor workability. It was a flaw.

とができる。 As shown in FIG. 2, each sheet surface 4 of the joint portion of the multilayer insulation is brought into contact with a weight 5 or the like. Next, the joints between the plastic sides of each sheet are melted with heat. The following two methods are given as examples of how to melt the sheet, but other methods may also be used. In the method shown in FIG. 3, a thin needle 6 at high temperature is passed through the joints of the multi-layered sheets to melt the plastic sheets. On the other hand, in the method shown in FIG. 4, the horn 7 of an ultrasonic welder is applied to the joint part of the multilayer insulation, and the plastic sheet at the joint part is melted by generating heat by ultrasonic vibration. When the melted portions of the sheets are cooled, the sheets are welded together, resulting in a multilayer insulation in which the layers are joined to each other at the melted portions 8 of the sheets as shown in FIG.

現することができる。 As described above, according to the present invention, each sheet of multilayer insulation is joined by pressing a high-temperature needle or the horn of an ultrasonic welding machine against each sheet, which is easier than the conventional hand-sewing method. In addition, each layer of multilayer insulation can be quickly bonded.
