Preparation process of high-strength wear-resistant ceramic microsphere material and plunger
The invention relates to the technical field of plunger preparation, in particular to a high-strength wear-resistant ceramic microsphere material and a preparation process of a plunger. The ceramic material at least comprises the following raw materials in parts by weight: 41-58 parts of aluminum oxide, 2-8 parts of glass powder, 5-12 parts of feldspar, 11-18 parts of clay, 3-5 parts of a sintering aid and 1-6 parts of a grinding aid. The sintering aid is added to form a solid solution with a sinter, lattices are distorted and activated, the grinding aid is added to serve as a surface active agent, the crushing efficiency of the ceramic microspheres is improved, calcium oxide reacts with sodium citrate to generate calcium citrate, absorption of ceramic is facilitated, and the service life of the ceramic microspheres is prolonged. The expansion coefficient of generated ceramic microspheres is adjusted, the mechanical strength of a finished product is improved, and in addition, the material is endowed with fine tissues and excellent mechanical properties through a high-temperature and low-temperature combined secondary sintering technology.
本发明涉及柱塞制备技术领域，具体地说，涉及一种高强度耐磨型陶瓷微球材料及柱塞的制备工艺。其至少包括以下重量份的原料：三氧化二铝41‑58份、玻璃粉2‑8份、长石5‑12份、黏土11‑18份、助烧结剂3‑5份和助磨剂1‑6份。本发明中通过添加助烧结剂能与烧结物形成固溶体，使晶格畸变而得到活化，通过添加助磨剂作为表面活性剂，提高对陶瓷微球的粉碎效率，其中氧化钙与柠檬酸钠反应生成柠檬酸钙，以便于陶瓷的吸收，调节生成陶瓷微球的膨胀系数以及提高成品的机械强度，另外通过高温低温结合的二次烧结技术，赋予材料细小的组织和优良的力学性能。
