| Abstract: | Foaming boron-silicon denatured phenolic resin was synthesized by using boric acid and silicon sol and controlling the pH of the system. The results indicated that this material exhibited excellent heat resistance, its long-term using temperature reached 230 ℃, and its temperature of heat decomposition was 500 ℃ ,mass loss was 55% at 800 ℃. Meanwhile, the influence of the pH on foamability and stability of boron-silicon denatured phenolic resin was studied. The test results indicated that pH range of the system from 6.5 to 7.5 was appropriate. |
