Introduction

With the continuous development of aerospace technology, the radiation problems faced by spacecraft in the space environment are becoming increasingly prominent. High-energy particle radiation in space poses a serious threat to the spacecraft’s electronic equipment, material structure and the health of astronauts. Therefore, the development of materials with excellent radiation resistance has become a key link in spacecraft design. As a new polymer material, bis(3-diylpropyl)amine isopropyl alcohol ZR-50 (hereinafter referred to as ZR-50) has shown excellent radiation resistance in the outer protective layer of the spacecraft due to its unique chemical structure and physical properties. This article will introduce the product parameters, radiation resistance mechanism, application examples and their advantages in the outer protective layer of the spacecraft in detail.

1. Product parameters of ZR-50

ZR-50 is a polymer compound whose chemical structure contains multiple amine groups and alcohol groups, and these functional groups impart excellent radiation resistance to the material. The following are the main product parameters of ZR-50:

2. Radiation resistance mechanism of ZR-50

The radiation resistance of ZR-50 is mainly attributed to the amine and alcohol groups in its molecular structure. These functional groups can effectively absorb and disperse the radiation of high-energy particles, thereby reducing the radiation to the internal structure of the materialdestroy. Specifically, the radiation resistance mechanism of ZR-50 includes the following aspects:

2.1 Radiation absorption

The amino groups and alcohol groups in the ZR-50 molecule have high electron density and can effectively absorb high-energy particle radiation. When radiation particles interact with ZR-50 molecules, these functional groups are able to absorb radiation energy and convert it into thermal energy or other forms of energy, thereby reducing direct damage to the internal structure of the material by radiation.

2.2 Radiation Dispersion

The multiple amine groups and alcohol groups in the ZR-50 molecule can also disperse the absorbed radiation energy throughout the material through intermolecular interactions. This dispersion can effectively reduce the radiation dose in the local area, thereby reducing the overall damage to the material by radiation.

2.3 Free radical capture

Under the action of radiation, a large number of free radicals will be generated inside the material, which will further induce the degradation and destruction of the material. The amino groups and alcohol groups in the ZR-50 molecule can effectively capture these free radicals, thereby preventing the chain reaction caused by the free radicals and protecting the structural integrity of the material.

The ZR-50 can be used as a coating material for the spacecraft shell, and through its excellent radiation resistance, it protects the spacecraft internal equipment from radiation damage. The following are the main performance parameters of ZR-50 coating:

3.2 Protection of spacecraft electronic equipment

Electronic devices in spacecraft are extremely sensitive to radiation, which can cause the performance of electronic components to degrade or even fail. ZR-50 can act as a protective material for electronic devices, and protects electronic devices from radiation damage through its excellent radiation resistance. The following is ZR-50 in electronic equipment protectionApplication parameters in the protection:

3.3 Spacecraft Solar Panel Protection

Solar panels are important energy equipment for spacecraft, and radiation will cause the efficiency of solar panels to decrease.
