Abstract

The invention relates to a radar hood temperature-resistant coating material and a preparation method thereof, and solves problems that in the prior art that a radar hood coating material generally can not bear high and low temperatures or is easy to crack under high and low temperatures, and is short in service life. The temperature-resistant coating material comprises the following raw materials: pure thermosetting liquid polyimide resin, linear low-density polyethylene, hydroxyl-terminated polybutadiene, isobutyltriethoxysilane, expanded graphite, gas-phase white carbon black, polyethylenewax, a dispersant, and an antioxidant. The coating material is prepared with a scientific and ratio-rigorous formula; the obtained temperature-resistant coating material has the advantages of being capable of resisting high and low temperatures, having low probability of cracking at high and low temperatures, and being capable of resisting temperature of 150-200 DEG C and long in service life; thepreparation method is simple, preparation conditions are mild, the industrial production is easy to realize, and the application is wide.

Description

technical field [0001] The invention relates to the technical field of military materials, in particular to a heat-resistant coating material for a radome and a preparation method thereof. Background technique [0002] Radar products are large electronic devices used in harsh environments, and the protection of their surfaces is particularly important. In the prior art, coatings are often used on the surface of radomes to improve their surface protection performance; however, in extreme environments, it is often required that the surface coatings of radomes have a wide range of temperature resistance to protect radars from environmental damage. The existing coating materials for radome generally have problems such as narrow temperature resistance range, brittle coating, and short service life. Based on the above statements, the present invention proposes a heat-resistant coating material for a radome and a preparation method thereof. Contents of the invention [0003] Th...
