    On June 17, the Shenzhou 12 manned spacecraft was successfully launched at the Jiuquan Satellite Launch Center
    .
    After five years, the Shenzhou spacecraft once again escorted the astronauts into space
    .
    Compared with the predecessors in gray coats, the Shenzhou 12 manned spacecraft is full of silver and shiny, and the cool and fashionable new "coat" can not help but make people shine
    .
    This beautiful "coat" is a new type of "low absorption-low emission thermal control coating" carefully developed by the 529 Factory of the Fifth Academy of China Aerospace Science and Technology Group for two years
    .

    .
    The space environment of Shenzhou XII
    ● Stay in the space station for a long time ● The surface temperature of the cabin facing the sun will be as high as 90℃ ● The surface temperature of the cabin facing the sun will be as low as -30℃
    ● Experience long-lasting space high-intensity ultraviolet Irradiation ● A variety of charged particles combined with the constant bombardment of high-speed atomic oxygen ● Material loss is very serious.
    In such a harsh environment, it is even more necessary to wear a special coat for the Shenzhou 12 manned spacecraft.
    Protect the barrier .








    "Low Absorption-Low Emission Thermal Control Coating" ● A thermal control material sprayed on the outer surface of the spacecraft
    .
    In a high vacuum environment, only through a method of temperature change in the form of heat radiation, such as thermal control coating, can the outer surface temperature expected by the designer be reached
    .
    ● Through its own low absorption and strong reflection ability of solar radiation, it can greatly reduce the internal temperature rise phenomenon of the spacecraft exposed to the sun for a long time, and then through its own extremely low infrared emission characteristics, it can reduce radiation leakage when the spacecraft is on the backside of the sun.
    Heat greatly slows down the temperature drop rate in the cabin, and has the effect of heat preservation
    .
    ● It has the function of resisting the constant high-energy ultraviolet radiation, atomic oxygen bombardment, and a variety of high-energy particles and ionizing radiation attacks in space.
    It is a full-time protective suit for Shenzhou 12 all day long
    .
    In order to develop this new type of functional material, the development team determined two key technical indicators of low absorption and low emission of thermal control coatings, and then used these two technical indicators as a starting point to carry out coating design, simulation, preparation, testing and testing.
    A series of research and development work including project implementation
    .
    In the process of repeated tests, through repeated summaries and improvements, the development team lasted two years of hard work, from the initial development of a new low-absorption and low-emission thermal control coating to the painting of the Shenzhou 12 manned spacecraft, and then to the follow-up All manned spacecraft have been retrofitted and applied one after another, breaking through a number of key technologies in the development of coatings, and successfully realized a new coating material that meets the expected design requirements, ensuring that the astronauts can have a more comfortable cabin environment and successfully complete the follow-up Various tasks
    .

    The level of interstellar exploration represents the most cutting-edge technology and productivity of a country
    .
    Among them, nuclear batteries and high-end aerospace coatings have always been the "stuck neck" technology used by the United States and Western countries to curb China's development
    .
    China's aerospace industry has overcome technical difficulties and broken through numerous obstacles.
    After several stages of development of missiles, launch vehicles, artificial satellites, and manned spaceflight, it has achieved remarkable achievements that have attracted the attention of the world
    .
    This year, my country’s aerospace industry is very exciting.
    In 2021, China’s annual space launches are expected to exceed 40 for the first time.

    The prosperity of the aerospace industry is inseparable from the efforts of astronauts, and it is also inseparable from all kinds of sophisticated aerospace technologies .
    As a paint coating that is closely related to spacecraft, it is a topic that paint people talk about .
    In addition to the traditional protection and decoration functions of aerospace and aviation coatings, they are also reflected in their special functions, such as high temperature resistance, ablation resistance, heat insulation, corrosion resistance, stealth, and corrosion resistance, etc.
    , so the technical level of aerospace and aviation coatings In a sense, it represents the level of development of a country's aviation industry .
    What are the characteristics of high temperature resistant and anticorrosive coatings in the aerospace field? ● Ability to withstand comprehensive radiation such as ultraviolet, electron, proton, etc.
    ● High requirements for outgassing rate ● High and low temperature cycle With the continuous development of China's aerospace industry, special coatings for satellites and missiles have also been successfully studied, and the main varieties are high temperature resistance coating, heat ablative coating, thermal control coatings, high temperature cable insulating coating, the high temperature insulating tape, alkali coatings .
    Among them, high temperature resistant coatings, ablative heat-resistant coatings, and thermal control coatings are widely used in aerospace .
    The paint used by the Long March 7 Yao-2 carrier rocket carrying China's first cargo spacecraft Tianzhou-1 is a good display and popular science of aerospace paint .
    Long March No.

    The special "four-proof" paint can ensure that the rocket is anti-humidity, anti-salt spray, anti-mold and anti-static
    .
    It will not be corroded if placed in a fungus box for 1 month; under 144 hours of alternating hot and cold environments, the coating will not bubble, crack, or debond; it can withstand 96 hours of alternating salt spray spray
    .
    According to the survey, the production institutions of China's special aerospace coatings mainly include the former Coating Industry Research Institute of the Ministry of Chemical Industry, Beijing 621 Institute, Tianjin Paint Factory, Shanghai Coating Research Institute and Xi'an Hui'an Chemical Factory.

    China has developed its own aviation coatings since the 1950s.
    After decades of development, the technology has become more mature, and the rise of national coatings has laid a solid foundation for the development of China's high-tech fields.
    The foundation, whether it is navigation or aerospace, can be seen in every great undertaking as a national paint company .
    I believe that in the future, more and more ethnic paints will participate in various high-tech buildings in our country .
