High-strength wear-resistant composite material as well as preparation method and application thereof
The invention discloses a high-strength wear-resistant composite material as well as a preparation method and application thereof. The high-strength wear-resistant composite material comprises glue and filler, wherein the glue comprises modified resin and a composite curing agent, the modified resin is at least one of E51 resin, NPEF170 resin and F51 resin which are blended and modified through hyperbranched polymers, the composite curing agent comprises a main curing agent and an accelerant, the main curing agent comprises at least one of a modified alicyclic amine curing agent and a modified aromatic amine curing agent, the accelerant is DMP-30, and the filler comprises SiC, Al2O3, PTFE, MoS2, graphite and SiO2. The high-strength wear-resistant composite material disclosed by the invention has the advantages of high strength, small pores, easiness in forming, oil resistance, acid and alkali resistance and high thermal stability, can meet various physical property requirements of machine tool body guide rails and base type guide rail parts on the composite material, and is low in comprehensive cost and good in shock absorption.
本发明公开了一种高强度耐磨复合材料及其制备方法和应用，高强度耐磨复合材料包括胶剂和填料，胶剂包括改性树脂和复合固化剂，改性树脂为采用超支化聚合物共混改性的E51树脂、NPEF170树脂和F51树脂中的至少一种，复合固化剂包括主固化剂和促进剂，主固化剂包括改性脂环胺固化剂和改性芳香胺固化剂中的至少一种，促进剂为DMP‑30，填料包含SiC、Al2O3、PTFE、MoS2、石墨和SiO2。本发明的高强度耐磨复合材料强度高、气孔小、易成形，具有耐油、耐酸碱和热稳定性高的优点，能够满足机床床身导轨及底座类导轨零件对复合材料的各项物理性能要求，且综合成本低、吸震性好。
