Aluminum titanate ceramic nozzle material
The invention relates to the field of ceramic materials, in particular to an aluminum titanate ceramic nozzle material. The composite material is prepared from the following raw materials: 70 to 90 parts of aluminum titanate, 5 to 10 parts of nonmetal carbide, 15 to 30 parts of metal oxide, 4 to 8 parts of N-hydroxymethyl acrylamide, 1 to 3 parts of octavinyl-POSS, 3 to 6 parts of carboxymethylated chitosan crosslinked microspheres, 0.1 to 0.5 part of a dispersant, 0.1 to 0.5 part of a free radical initiator and 200 to 300 parts of a solvent. The prepared aluminum titanate ceramic nozzle material has high density and low thermal expansion coefficient, and the bending strength reaches up to 65 MPa or above.
本发明涉及陶瓷材料领域，具体为一种钛酸铝陶瓷喷嘴材料，以重量份数计，由以下原料制备而成：钛酸铝70‑90份、非金属碳化物5‑10份、金属氧化物15‑30份、N‑羟甲基丙烯酰胺4‑8份、八乙烯基‑POSS 1‑3份、羧甲基化壳聚糖交联微球3‑6份、分散剂0.1‑0.5份、自由基引发剂0.1‑0.5份、溶剂200‑300份，本发明所制备的钛酸铝陶瓷喷嘴材料具有较高的密度和较低的热膨胀系数，而且抗弯强度高达65MPa以上。
