| Abstract: | The formula and processing technology of NBR/asbestos/SiO 2 insulating material are studied to improve the low temperature resistance and ablation resistance of the material. The results show that the brittle temperature of the improved insulating material drops and the ablation resistance of the insulating material is improved by carefully selecting the ingredients including the type of NBR,asbestos and SiO 2.With the reasonable calendering techniques,the NBR layer shows the acceptable performance which is superior to the classic NBR insulating and the phenolic modified NBR insulation material. |
