High-temperature-resistant ceramic type bearing core plasticizer
The invention discloses a high-temperature-resistant ceramic type bearing core plasticizer. The plasticizer material is prepared from the following chemical components in percentage by mass: 93-97% ofparaffin, 1.5-2% of beewax, 1-3% of polyethylene and 0.5-2% of modified graphene. The preparation method comprises the following steps: uniformly mixing paraffin, beeswax and a polyethylene materialaccording to a certain mass percentage by using a ball mill; heating and melting the uniformly mixed materials into slurry, adding the modified graphene material into the slurry, and stirring at a high speed until the raw materials are fully mixed; and condensing the slurry into blocks to obtain the graphene reinforced plasticizer material. According to the invention, a graphene material with excellent mechanical properties and thermal properties is introduced into a paraffin-based plasticizer material system; the temperature adaptability and the dimensional stability of the paraffin-based plasticizer material are improved, and uniform mixing of graphene in the paraffin-based plasticizer is realized, so that the graphene-reinforced paraffin-based plasticizer material which is good in fluidity, small in green body shrinkage, high in green body temperature adaptability strength, not easy to deform and high in molding rate is obtained.
一种耐高温陶瓷型轴承芯增塑剂，所述增塑剂材料按照质量百分比的化学组成为：石蜡93％～97％，蜂蜡1.5％～2％，聚乙烯1％～3％，改性石墨烯0.5％～2％。制备方法包括：按照一定质量百分配比，将石蜡、蜂蜡、聚乙烯材料采用球磨机混匀；将混匀的材料加热融化为浆料，将改性石墨烯材料加入到浆料中，高速搅拌直至原料充分混合；将浆料冷凝成块状，制得石墨烯增强增塑剂材料。本发明将具有优异力学性能及热性能的石墨烯材料引入石蜡基增塑剂材料体系，提高了石蜡基增塑剂材料的适温性能及尺寸稳定性，实现石墨烯在石蜡基增塑剂中均匀混合、以获得流动性好、素胚收缩小、素胚适温强度高、不易变形、成型率高的石墨烯增强石蜡基增塑剂材料。
