Document Type and Number:
WIPO Patent Application WO/2022/111288
Kind Code:
A1
Abstract:
A weather-resistant silazane rubber with a three-dimensional network structure and a preparation method therefor, which belongs to the field of special rubber materials, and also belongs to the field of high-temperature thermal protective materials. The preparation method therefor comprises the following steps: reacting 3-butenyl methyl dichlorosilane and high-purity ammonia gas under the action of ammonium chloride and a metal sodium catalyst to produce 3-butenyl methyl cyclotrisilazane, and then vulcanizing same into a rubber material by adding an inorganic auxiliary agent and a catalyst. The resulting rubber material has excellent mechanical properties and anti-aging properties, and an excellent high-temperature resistance.
