Hexagonal boron nitride material as well as preparation method and application thereof
The invention provides a hexagonal boron nitride material and a preparation method and application thereof, and the preparation method comprises the following steps: carrying out hydrophilic modification treatment on a hexagonal boron nitride raw material to obtain a modified hexagonal boron nitride raw material; mixing the modified hexagonal boron nitride raw material, a surfactant, a polymer binder, a sintering aid and a dispersion medium to prepare second slurry; performing spray drying on the second slurry to form a spherical particle product; and sintering the spherical particle product to obtain the hexagonal boron nitride material. According to the method, the sphericity, size and other properties of the hexagonal boron nitride material can be improved, the filling amount of the hexagonal boron nitride material in the heat-conducting composite material is increased, and the viscosity of the heat-conducting composite material is reduced.
本发明提供一种六方氮化硼材料及其制备方法和应用，所述制备方法包括以下步骤：将六方氮化硼原料进行亲水性改性处理，得到改性六方氮化硼原料；将所述改性六方氮化硼原料、表面活性剂、聚合物粘结剂、烧结助剂和分散介质混合，制成第二浆料；将所述第二浆料进行喷雾干燥，形成球形颗粒产物；将所述球形颗粒产物进行烧结，得到所述六方氮化硼材料。本发明能够提高六方氮化硼材料的球形度和尺寸等性质，提高六方氮化硼材料在导热复合材料中的填充量，降低导热复合材料的粘度。
