The invention provides a high-strength low-expansion rare earth ceramic tableware and a preparation process thereof. The ceramic tableware comprises, by weight, 70-80 parts of high-dispersion modifiedkaolin, 6-11 parts of thermoplastic polyurethane resin, 2-5 parts of rare earth oxide, 3-7 parts of a filler, 0.5-1.5 parts of copper acetate and 1-2 parts of a silane coupling agent. Through reasonable raw material selection and pretreatment, the compatibility of the components is effectively improved, the overall reaction bonding property is strong, the thermal expansion coefficient of the ceramic material is reduced, and the ceramic tableware has excellent mechanical properties and shock resistance stability, compact and stable structure, good antibacterial property and environmental protection property, and significantly improved comprehensive quality.
本发明提出了一种高强度低膨胀稀土陶瓷餐具及其制备工艺，该陶瓷餐具包括以下重量份数组份：高分散改性高岭土70‑80份、热塑性聚氨酯树脂6‑11份、稀土氧化物2‑5份、填料3‑7份、醋酸铜0.5‑1.5份、硅烷偶联剂1‑2份，本发明通过合理的原料选配和预处理，有效提高了组份间的配伍作用，整体反应联结性强，不仅降低了陶瓷材料的热膨胀系数，同时具有优异的力学性能和抗震稳定性，结构致密稳定，同时具有良好的抗菌性和环保性，综合质量显著提高。
