Resin ceramic wear-resistant composite material and preparation method thereof
The invention provides a resin ceramic wear-resistant composite material and a preparation method thereof. The method comprises the steps: firstly, respectively preparing a polyurethane prepolymer, an epoxy resin component and a curing agent component; then premixing silicon carbide and brown fused alumina filler, and then mixing with a polyurethane prepolymer, an epoxy resin component, a curing agent component, a silane coupling agent, a dispersing agent and a defoaming agent to obtain a castable of the composite material; and finally, injecting the castable into a mold, curing and molding, and demolding to obtain the resin ceramic wear-resistant composite material. The mass fraction of the composite material ceramic filler prepared by the method can reach 87%, the composite material is firmly combined with an embedded part, cracks caused by stress are avoided, the composite material is particularly suitable for manufacturing flow passage components of large transmission equipment, and the prepared wear-resistant composite material flow passage component has the service life in the same working condition environment up to 8 times or more of that of a traditional high-chromium alloy material flow passage component.
本发明提供了一种树脂陶瓷耐磨复合材料及其制备方法，该方法首先分别制备聚氨酯预聚体、环氧树脂组分和固化剂组分；然后将碳化硅和棕刚玉填料预混后再与聚氨酯预聚体、环氧树脂组分、固化剂组分、硅烷偶联剂、分散剂和消泡剂进行混合，得到复合材料的浇注料；最后将浇注料注入模具并固化成型，脱模后得到树脂陶瓷耐磨复合材料。该方法制备的复合材料陶瓷填料质量分数可达87%，复合材料与预埋件结合紧固，无应力造成的裂纹，特别适合制作大型传输设备的过流部件，制备的耐磨复合材料过流部件，同等工况环境使用寿命最高可达传统高铬合金材料过流部件的8倍以上。
