Embodiment Construction

[0007] The radiation shielding device according to the present invention has a three-layer structure, and includes a titanium metal layer, a metal / polymer composite material layer, and an aluminum metal layer sequentially from outside to inside with respect to the electronic device to be protected, that is to say, the aluminum metal layer is closer to The electronic device to be protected and the layer of material to which it is bonded. Adhesives can be used to bond the three-layer structure into a board. Preferably, the thicknesses of the titanium metal layer, the metal / polymer composite material layer and the aluminum metal layer are 1 mm, 0.2 mm and 1 mm respectively.

[0008] Preferably, the metal / polymer composite material layer comprises metal powder comprising tungsten, titanium and aluminum and phenolic resin and a small amount of curing agent. Preferably, the metal / polymer composite material layer comprises by weight 78% metal powder, 20% phenolic resin and 2% curing...

Abstract

The invention relates to a radiation shielding device which comprises a titanium metal layer, a metal / polymer composite material layer and an aluminum metal layer, wherein the metal / polymer composite material layer contains metal powder, phenolic resin and a curing agent, and the metal powder contains tungsten, titanium and aluminum; by weight, the metal / polymer composite material layer contains 78 percent of metal powder, 20 percent of phenolic resin and 2 percent of curing agent; the metal powder contains tungsten, titanium and aluminum of which the weight ratio is 4:1:1; the curing agent is diethylenetriamine. The radiation shielding device has the advantages of thin thickness, light quality and good shielding effect.

Description

technical field [0001] The invention relates to a radiation shielding device, in particular to a radiation shielding device for a space spacecraft. Background technique [0002] During the satellite's orbit, it is inevitable to encounter the radiation of various space charged particles. The accumulation of electrons and protons in the device for a long time in the space radiation environment will produce an ionization effect in the semiconductor, resulting in changes in the electrical performance parameters of the device and causing abnormal operation of the device. Therefore, in order to ensure that the satellite will not be damaged or failed due to space radiation effects during the satellite’s in-orbit operation, all countries in the world must, according to the charged particle radiation environment of the satellite’s actual orbit, carry out some damage to the surface and interior of the satellite during the satellite development process. For radiation-sensitive key equ...
