Abstract
A kind of anti-oxidation coating suitable for honeycomb-enhanced low-density thermal protection material was studied.The processing property,microstructure of surface,heat resistance of the anti-oxidation coating were investigated,and the ablative property was assessed by muffle furnace ablation test,plasma ablation test and radiation heating test.The results indicates that the solvent content of anti-oxidation coating should be in range from 25％to 75％,its pot-life is greater than 165 min and its thickness is less than 300 μm.The thermal stability of the phenolic resin STN-1 coating is better than that of the methylphenyl silicon rubber 218-1.After being exposed to 800 ℃/10 min,a relatively obvious ceramicization phenomenon occurs in the coating.Under the conditions of 1 MW/30 s and 1.5 MW/30 s,a hard and dense carbon layer is formed.Under the radiation heating environment of 2 000 ℃ for 300 s,the back surface temperature of the honeycomb-reinforced low-density heat resistance material with coating is reduced by 10 ℃,and the strength of the carbon layer is higher.关键词
