Instrument identifier for deep space probe

Abstract

The invention provides an instrument identifier for a deep space probe. The instrument identifier mainly comprises a polyimide film in 125-mocrometer thickness and a surface composite coating, wherein the surface composite coating is printed onto the polyimide film by the screen printing process; taking the weight of the surface composite coating as 100%, the surface composite coating comprises the following chemical components in percentage by weight: 55-65% of organic silicon resin, 24-36% of modified resin, 3-5% of organic pigment and 4-8% of an additive. When the base material and the surface composite coating are to be selected, the environmental constraint problems of space radiation, vacuum, lunar dust, large high-low temperature differences, mechanics and the like are taken into full consideration, so that the selected composite coating is high in capability of irradiance resistance, strong in performance of high-low temperature resistance and large in intensity of mechanics resistance.

Description

technical field [0001] The invention belongs to the technical field of aerospace loads, and in particular relates to a device watch identification of a deep space probe. Background technique [0002] The logo is an important symbol of each spacecraft, and the logo carried on the spacecraft has certain political significance and engineering display. According to the mission requirements of the lunar exploration project, my country's lunar probes need to carry various signs, such as a certain flag, and during the mission, the camera will image the carried signs to improve the display of the project. [0003] At present, the logos carried on domestic and foreign spacecraft are mainly the flags of various countries. The details are as follows: [0004] On July 20, 1969, American astronaut Neil Armstrong stepped out of the lunar module of the "Apollo 11" spacecraft, leaving the first footprints of human landing on the lunar surface, realizing the dream of human landing on the mo...

AI Technical Summary

Problems solved by technology

Conventional materials do not have the space environment resistance performance that meets the requirements; the quality of metal materials is relatively large; although F46 film has good space environment resistance performance and light weight, F46 has very high chemical stability and is not easy to form a strong bond with other materials. Chemical bonds, it is difficult to prepare a high-adhesion coating on the surface of F46, which still cannot meet the requirements for making the lunar probe's watch label
