Preparation process of silicon nitride ceramic sheet formed by in-situ polymerization
The invention relates to a preparation process of an in-situ polymerization molded silicon nitride ceramic sheet, which comprises the following production steps of: uniformly mixing one or more liquid acrylic monomers, one or more liquid epoxy resin with small molecular weight and low viscosity and a radical initiator with a proper proportion at normal temperature, and then adding high-purity micro-nano silicon nitride powder into the mixture to prepare the in-situ polymerization molded silicon nitride ceramic sheet. And adding the dispersing agent and the inorganic sintering aid together, and thoroughly and uniformly mixing in a planetary mixer or a screw kneading machine. According to the in-situ polymerization molding silicon nitride production process, an organic solvent is not used, a drying and discharging process is avoided, the liquid acrylate monomer and the low-molecular-weight epoxy resin are used as dispersion media, the energy consumption is low, the speed is high, the occupied area of equipment is small, and the manufactured green sheet is accurate in size, few in defect and high in yield.
本发明涉及一种原位聚合成型氮化硅陶瓷薄片的制备工艺，生产步骤包括一种或数种液体丙烯酸单体，一种或数种小分子量低粘度的液体环氧树脂，和适当比例的自由基引发剂在常温下混合均匀，然后将高纯度的微纳米级的氮化硅粉体，分散剂，无机烧结助剂一起加入，在行星混合机或螺杆捏合机中彻底混合均匀。本发明的原位聚合成型氮化硅生产工艺，该工艺不使用有机溶剂，无烘干排放过程，利用液体丙烯酸酯单体和低分子量环氧树脂作为分散介质、能耗小、速度快，设备占地面积小，制造的生胚片尺寸精确，缺陷少，成品率高。
