Ceramic surface hot die-casting forming slurry and preparation process
The invention discloses ceramic surface hot die-casting forming slurry and a preparation process thereof. The ceramic surface hot die-casting forming slurry comprises slurry and an adhesive, wherein the slurry is prepared from, by mass, 30-40% of SiO2, 30-35% of Al2O3, 10-15% of CaO, 2-10% of Na2O, 10-15% of BaO, 2-6% of ZrO2, 1-5% of kaolin and 2-5% of silica powder, the adhesive comprises paraffin, a surfactant and a grinding aid, and weighing, ball milling and hot die casting are carried out. According to the invention, in the preparation process, the addition amount of paraffin in the waxslurry blank is improved by proportioning the raw materials and determining the optimal addition amount of the surfactant, the ball milling efficiency can be improved when sodium lignin sulfonate is used as a grinding aid, and the shrinkage rate of the formed ceramic blank can be reduced by reducing the content of paraffin in the wax slurry blank, so that conditions are created for preparing high-performance aluminum oxide ceramic materials.
本发明公开了一种陶瓷表面热压铸成型浆料及制备工艺，包括浆料和粘接剂，所述浆料按以下质量百分比称取原料：SiO2 30‑40％，Al2O3 30‑35％，CaO 10‑15％，Na2O 2‑10％，BaO 10‑15％，ZrO2 2‑6％，高岭土1‑5％，硅微粉2‑5％，所述粘接剂包括石蜡、表面活性剂和助磨剂，通过称重，球磨和热压铸，本制备工艺中，通过在原料组成配比，以及确定表面活性剂的最佳加入量，来改进蜡浆坯料中石蜡的加入量，同时通过木质素磺酸钠作助磨剂时可以提高球磨效率，通过减少蜡浆坯料中石蜡的含量，可以降低成型后陶瓷坯体的收缩率，从而为制备高性能氧化铝陶瓷材料创造条件。
