Silicon carbide lightweight sealing ring and preparation method thereof
The invention discloses a silicon carbide lightweight sealing ring, which is prepared from the following raw materials in parts by weight: 50 to 70 parts of silicon carbide, 30 to 40 parts of boron carbide, 1 to 5 parts of zirconium oxide, 8 to 12 parts of phenolic resin, 3 to 8 parts of binding agents, 0.8 to 1.2 parts of dispersing agents, 1 to 3 parts of glycerol and 3 to 8 parts of carbon black. The silicon carbide light-weight sealing ring has the beneficial effects that boron carbide and zirconium oxide are added in the preparation process of the silicon carbide light-weight sealing ring, so that the volume density of the sealing ring is lower, the working mass is lighter under the condition of the same volume, and the silicon carbide light-weight sealing ring has better heat conductivity coefficient, hardness, bending strength and reliability; according to the silicon carbide light-weight sealing ring, the pressureless sintering process is adopted, large-batch production of the silicon carbide light-weight sealing ring can be achieved, and the production cost of the silicon carbide light-weight sealing ring is reduced.
本发明公开了一种碳化硅轻量型密封环，包括下述重量份的原料：碳化硅50‑70份、碳化硼30‑40份、氧化锆1‑5份、酚醛树脂8‑12份、粘结剂3‑8份、分散剂0.8‑1.2份、甘油1‑3份、炭黑3‑8份。本发明的有益效果为：本发明所述碳化硅轻量型密封环在制备过程中加入了碳化硼和氧化锆，使所述的密封环体积密度更低，相同体积的工作质量就更轻，且具有更优的导热系数、硬度、弯曲强度及可靠性；本发明所述碳化硅轻量型密封环采用无压烧结工艺，可使碳化硅轻量型密封环实现大批量的生产，降低了其生产成本。
