The invention discloses a preparation method of a heat-resistant reinforced self-healing polyborosiloxane composite material. The composite material mainly comprises 60-100 parts of active silicone oil, 5-35 parts of boric acid, 15-40 parts of filler, and adhesion promoting force. The self-healing composite material specifically involves the preparation of a polyborosiloxane elastomer formed by borate and active silicone oil supplemented by heat-resistant reinforcing fillers; The preparation method is low in price and simple in preparation. In the present invention, the hydrogen bond formed between the boron/oxygen coordination bond and boric acid (BA) can be broken and reconstructed. Secondly, by adjusting the ratio of borate to active silicone oil, its high-efficiency self-healing ability can be self-regulated. . And fillers such as carbon nanotubes and ferric oxide and polyborosiloxane have a synergistic effect in heat resistance, making them have high mechanical strength and thermal stability. |
