Abstract

The invention discloses a strong-laser-ablation-resistant protective coating and a preparation method thereof. The protective coating is prepared from flake graphite, a SiC whisker, an epoxy modified organic silicon resin and a phenolic resin. The preparation method comprises the following steps: dissolving the epoxy modified organic silicon resin and phenolic resin, stirring to obtain a mixed adhesive, and mixing the flake graphite and SiC whisker to obtain mixed powder; (2) mixing the mixed adhesive and mixed powder, and carrying out ball milling to obtain a coating slurry; and (3) coating the coating slurry on a base material, and curing by heating to obtain the strong-laser-ablation-resistant protective coating. The strong-laser-ablation-resistant protective coating has the advantages of low density, high strength, low price, stable performance and the like, and can be sprayed. The preparation method has the advantages of simple technique and low cost.

Description

technical field [0001] The invention relates to a protective coating and a preparation method thereof, in particular to a protective coating resistant to strong laser ablation and a preparation method thereof. Background technique [0002] Laser weapons have incomparable advantages such as speed (speed of light), precision, anti-electronic interference and other weapons, and will soon become one of the important means of combat in modern high-tech conditions. With the rapid development of laser weapons, especially high-energy laser weapons, space vehicles are facing more and more dangers from laser weapons. The damage methods of laser weapons to targets can be divided into soft damage and hard damage. Soft damage is to cause interference, blinding and damage to the optical film or photoelectric sensor of the aircraft. The laser energy density required for it is relatively low, only 10-10 2 J / cm 2 . Hard damage is the increase of the temperature of the structural parts of...
