摘要
通过制备环氧化桐油酸甲酯,并将其与E51环氧树脂共混,得到桐油基环氧树脂。再用硅烷偶联剂KH-570改性纳米SiO_(2),并以不同的质量比添加到桐油基环氧树脂中,探究不同纳米SiO_(2)含量在力学性能、接触角以及耐磨损性能上对桐油基环氧树脂复合材料的影响。结果表明:质量比为6%的纳米SiO_(2)的桐油基环氧树脂复合材料的拉伸和冲击强度都得到了提高,冲击强度较未加入纳米SiO_(2)提高了53.3%,水接触角也从93.3°提高到104.76°,并且添加纳米SiO_(2)之后复合材料的耐磨损性能也随之增强。
Tung oil-epoxy resin was obtained through blending produced epoxidized methyl eleostearate with E51 epoxy resin.Nano-SiO_(2)was modified by silane coupling agent KH-570 and added to tung oil-based epoxy resin with different mass ratio.The effects of different nano-SiO_(2)contents on mechanical properties,contact angle and wear resistance of tung oil-epoxy resin composites were investigated.The results showed that the tensile and impact strength of tung oil-epoxy resin composites with 6%nano-SiO_(2)were improved.The impact strength was 53.3%higher than that without nano-SiO_(2),and the water contact angle was also increased from 93.3°to 104.76°.After adding nano-SiO_(2),the wear resistance of the composites was also enhanced.
