Abstract

The invention provides a nitrine type high-molecular sensitized high-energy ablator which comprises the components by weight part: 5 to 80 parts of nitrine type material, 5 to 70 parts of high energy material and 5 to 15 parts of additive. The invention also provides a preparation method of the ablator and a target belt made from the ablator. According to the invention, an ablative material layer made via the method utilizes the viscous characteristic of the nitrine type high-molecular sensitized high-energy material, integrates the energy of the nitrine type material and the high energy material, and has the advantages of low ablative threshold value, high energy content and viscosity; and the cohesive property between a substrate and the ablator meets the use requirement, and the utilization rate of the laser energy can also meet the use requirement.

Description

technical field [0001] The invention belongs to the technical field of laser propulsion, and in particular relates to an azide polymer sensitized high-energy ablation material, a preparation method thereof, and a target tape prepared by the same. Background technique [0002] Laser micro-propulsion technology can realize the attitude control and orbit maintenance of small satellites. It has the advantages of small impulse bit, light system weight, wide adjustable range of thrust, and no-nozzle structure. alternative status. Due to the weight and energy limitations of small satellites, it is necessary to use a laser with a lower power (≥1W). The etching material must be a polymer material with low thermal conductivity. At present, the target material for laser micro-propulsion is composed of a substrate and an ablation layer. In order to ensure the service life of the thruster, the target material must have a certain length (tens of centimeters to hundreds of meters), width...
