Preparation and Properties of Nano-silica/Tung Oil-Epoxy Resin Composites
Tung oil-epoxy resin was obtained through blending produced epoxidized methyl eleostearate with E51 epoxy resin.Nano-SiO2 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-SiO2 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-SiO2 were improved.The impact strength was 53.3%higher than that without nano-SiO2,and the water contact angle was also increased from 93.3° to 104.76°.After adding nano-SiO2,the wear resistance of the composites was also enhanced.
