Embodiment Construction

[0009] The technical scheme of the present invention will be further elaborated below.

[0010] The above-mentioned thermal insulation material used in ultra-high vacuum includes alternately laminated plastic foam layers and metal layers, and the metal layer is plated on the plastic foam layer by vacuum plating.

[0011] The number of laminated metal layers and plastic foam layers is selected according to different requirements for heat insulation effects. When the heat insulating material is used, the metal layer is located in the innermost layer, that is, close to the object to be heat insulated.

[0012] According to the different shapes of the objects to be insulated, the shapes of the laminated metal layer and the plastic foam layer are designed.

[0013] In this embodiment, the plastic foam layer is a polyimide foam layer made of polyimide material; the metal layer is made of one or two or three materials among aluminum, silver and gold. In this embodiment, the metal l...

Abstract

The invention discloses a thermal insulation material used in ultra-high vacuum, which comprises alternately stacked plastic foam layers and metal layers, and the metal layer is vacuum plated on the plastic foam layers. The invention is a heat insulation material used in ultra-high vacuum, which has ultra-high vacuum compatible characteristics, can prevent heat conduction, heat radiation and heat convection; has the characteristics of lightness and low heat capacity; can be folded and is convenient for cutting; the The heat insulation material itself has a certain rigidity, and no additional support is needed during use, which reduces the cost of use and avoids heat loss caused by the support.

Description

technical field [0001] The invention relates to a heat insulating material used in ultra-high vacuum. Background technique [0002] Existing heat insulation materials for ultra-high vacuum are generally made of metal aluminum. Due to the thermal conductivity of metal aluminum, its thermal insulation effect is relatively poor. At the same time, when there is only metal aluminum in the heat insulating material, its mass is also relatively large, which is not easy to take out for maintenance. Contents of the invention [0003] The object of the present invention is to provide a heat insulating material for use in ultra-high vacuum, which has ultra-high vacuum compatible characteristics, low heat capacity, is foldable, and is easy to cut. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A thermal insulation material used in ultra-high vacuum, comprising alternately laminated plastic foam layers and metal layer...
