Polysilazane resin, preparation method and application thereof, and silicon nitride ceramic material
The invention provides polysilazane resin, a preparation method and application thereof and a silicon nitride ceramic material. The polysilazane resin provided by the invention comprises the following raw materials: first dihalogenated silane, second dihalogenated silane, trihalogenated silane and an amine compound, the molar ratio of the first dihalogenated silane, the second dihalogenated silane, the trihalogenated silane and the amine compound is 1: (0.1-0.3): (0.1-0.3), and the ratio of the total mole number of the first dihalogenated silane, the second dihalogenated silane and the trihalogenated silane to the mole number of the amine compound is 1: (2-4). The first dihalogenated silane, the second dihalogenated silane and the trihalogenated silane in a specific molar ratio are copolymerized with the amine compound, alkenyl is introduced into the polysilazane resin, meanwhile, the branching degree of the polysilazane resin is improved, the viscosity of the polysilazane resin is further improved, the viscosity of the polysilazane resin is 100-1000 mPa, and the viscosity of the polysilazane resin is improved. The requirement of the market on the high-viscosity polysilazane resin is effectively met.
本发明提供了一种聚硅氮烷树脂及其制备方法、应用和氮化硅陶瓷材料。本申请提供的聚硅氮烷树脂的原料包括第一二卤代硅烷、第二二卤代硅烷、三卤代硅烷和胺类化合物，且三者的摩尔比为1:0.1～0.3:0.1～0.3，第一二卤代硅烷、第二二卤代硅烷和三卤代硅烷的总摩尔数与胺类化合物的摩尔数之比为1:2～4。本申请采用特定摩尔比的第一二卤代硅烷、第二二卤代硅烷和三卤代硅烷与胺类化合物共聚，将烯基引入聚硅氮烷树脂的同时提高了聚硅氮烷树脂的支化度，进而提高了聚硅氮烷树脂的粘度，使其粘度为100～1000mPa，有效满足了市场对于高粘度聚硅氮烷树脂的需求。
