Ceramic granulation powder, preparation method thereof, ceramic material and mobile phone backboard
The invention relates to a ceramic granulation powder, a preparation method thereof, a ceramic material and a mobile phone backboard. The ceramic granulation powder contains 92-98 wt% of ceramic powder and 2-8 wt% of a binder by taking the dry basis weight of the ceramic granulation powder as a reference; on the basis of the dry base weight of the binder, the binder contains 85-95 wt% of an acrylic acid-acrylate copolymer and 5-15 wt% of a plasticizer; and on the basis of the dry base weight of the acrylic acid-acrylate copolymer, the acrylic acid-acrylate copolymer is prepared from 0.1-0.8 wt% of polyacrylic acid-polyhydroxy acrylate ester, 5-10 wt% of polyacrylic acid triethanolamine salt and 0.5-2 wt% of self-crosslinking polyhydroxy acrylate. A ceramic green body prepared from the ceramic granulation powder disclosed by the invention has relatively high strength, so that the ceramic material prepared from the ceramic granulation powder has relatively high hardness and few surface pits.
本公开涉及一种陶瓷造粒粉及其制备方法、陶瓷材料和手机背板，以陶瓷造粒粉的干基重量为基准，该陶瓷造粒粉含有92‑98重量％的陶瓷粉和2‑8重量％的粘结剂；以粘结剂的干基重量为基准，粘结剂含有85‑95重量％的丙烯酸‑丙烯酸酯共聚物和5‑15重量％的增塑剂；以丙烯酸‑丙烯酸酯共聚物的干基重量为基准，丙烯酸‑丙烯酸酯共聚物包括0.1‑0.8重量％的聚丙烯酸‑聚羟基丙烯酸酯酯化物，5‑10重量％的聚丙烯酸三乙醇胺盐，0.5‑2重量％的自交联聚羟基丙烯酸酯。由本公开的陶瓷造粒粉制备得到的陶瓷生坯具有较高的强度，进而使以其制备的陶瓷材料具有较高的硬度且表面坑点少。
