Abstract
The present disclosure provides a room-temperature-vulcanizing (RTV) silicone rubber foam with ablation resistance and high-efficiency heat insulation and a preparation method thereof. In the present disclosure, hydroxyl-terminated polydimethylsiloxane, vinyl-terminated polydimethylsiloxane, a catalyst, an inhibitor, a ceramifiable emulsion foaming agent, a functionalized ceramic filler, and a heat-resistant additive are placed in a planetary stirring tank, and stirred to obtain a base rubber A. The hydroxyl-terminated polydimethylsiloxane, the vinyl-terminated polydimethylsiloxane, a hydrogen-containing silicone oil, a functionalized low-melting glass powder, and functionalized hexagonal boron nitride are placed in the planetary stirring tank, and stirred to obtain a base rubber B. The base rubber B is transferred to the base rubber A, vulcanization is conducted, followed by after vulcanization in an oven to obtain a final product.
