Ceramic microsphere with amino silane coupling agent fixed on surface and preparation method thereof
The invention belongs to the technical field of ceramic microspheres, and particularly relates to a ceramic microsphere with an amino silane coupling agent fixed on the surface and a preparation method of the ceramic microsphere. Comprising the following components: calcined kaolin, spherical granular amorphous silicon powder, deionized water, a dispersing agent and a binder. The preparation method comprises the following steps: adding calcined kaolin, spherical granular amorphous silicon powder and deionized water into a ball mill, carrying out ball-milling mixing, adding a dispersant, carrying out ball-milling mixing, adding a binder, and carrying out ball-milling mixing to obtain slurry; carrying out spray drying, microsphere sintering, surface modification, alcoholysis reaction, addition reaction and ammonolysis reaction on the slurry through a centrifugal spray dryer. According to the invention, the ceramic material can be effectively helped to be uniformly and stably dispersed in an organic system; and the ceramic microspheres can be effectively combined with organic matters and inorganic matters in the material, so that the ceramic microspheres can effectively form a whole with other materials.
本发明属于陶瓷微球技术领域，具体涉及一种表面固定氨基硅烷偶联剂的陶瓷微球及其制备方法。包括组分为煅烧高岭土、球状颗粒非晶硅粉末、去离子水、分散剂、粘结剂。将煅烧高岭土、球状颗粒非晶硅粉末、去离子水加入球磨机中，球磨混料后加入分散剂，再球磨混料后加入粘结剂，再球磨混料得到浆料；将浆料通过离心喷雾干燥器喷雾干燥、微球烧结、表面改性、醇解反应、加成反应、氨解反应步骤完成。本发明可以有效地帮助陶瓷材料均匀稳定的分散于有机体系中；也可以有效的与材料中的有机物和无机物相结合，使陶瓷微球能够有效的与其他材料形成整体。
