High-performance sialon corundum plastic and preparation method thereof
The invention discloses a high-performance sialon corundum plastic which is prepared from the following raw materials in parts by weight: 50-75 parts of 3-5mm high-aluminum aggregate, 8-10 parts of 2-4mm brown fused alumina, 10-15 parts of 1-3mm mullite, 3-6 parts of 0.2-1mm aluminum oxide, 6-10 parts of 0.1-1 mm silicon micropowder, 3-8 parts of 10-20mm steel fiber, 4-7 parts of plasticizer, 5-10parts of a binding agent, and 1-2 parts of a coagulant. The invention relates to a preparation method of the high-performance sialon corundum plastic. The preparation method comprises the following steps: (1) taking high-aluminum aggregate, brown fused alumina, mullite and aluminum oxide, and mixing; (2) mixing in silicon micropowder and the steel fiber; (3) adding the plasticizer, the binding agent and the coagulant into a mixing mill, and stirring to obtain a pug; and (4) naturally drying the pug, carrying out static pressure molding, and carrying out heat treatment in a high-temperature environment under a nitrogen atmosphere condition. According to the present invention, the sialon is formed through the mutual solid dissolving of the materials, such that the plastic has advantages ofgood wear resistance, good thermal stability and good corrosion resistance.
本发明公开了一种高性能赛隆刚玉可塑料，由以下重量份的原料组成：高铝骨料3～5mm，50‑75份，棕刚玉2‑4mm，8‑10份，莫来石1～3mm，10‑15份，氧化铝0.2‑1mm，3‑6份，硅微粉0.1‑1mm，6‑10份，钢纤维10‑20mm，3‑8份，增塑剂4‑7份，结合剂5‑10份，促凝剂1‑2份。本申请一种高性能赛隆刚玉可塑料的制备方法，包括以下步骤：（1）取高铝骨料、棕刚玉、莫来石及氧化铝，混炼；（2）再取硅微粉、钢纤维进行混炼；（3）向混炼机内部投入增塑剂、结合剂及促凝剂，搅拌制得泥料；（4）将泥料自然干燥，并静压成型，之后在高温环境中，氮气气氛条件下热处理。本申请中，通过物料之间相互固溶形成赛隆（Sialon），使得本申请可塑料具备良好耐磨性、热稳定性及抗腐蚀性。
