摘要:以腰果酚合成了一种低粘度、高活性腰果酚含硅缩水甘油醚(SCGE),并将其作为稀释剂改性E-51环氧树脂/甲基六氢苯酐(MeHHPA)体系,通过粘度测试,红外光谱分析,力学性能测试,动态热机械分析(DMA)和断裂面形貌分析考察了SCGE用量对环氧固化物的结构及性能的影响。研究表明,SCGE对E-51树脂具有良好的稀释作用,可显著提高固化物的冲击强度与拉伸强度。当SCGE添加质量分数为15%时,固化物的冲击强度达到最大值17.53 k J/m^2,当SCGE添加质量分数为10%时,固化物的拉伸强度达到最大值73.63 MPa。SCGE对环氧固化物具有显著的增韧作用,但固化物的玻璃化转变温度(Tg)随着SCGE用量的增加有所降低。
The silicone-containing cardanol-based glycidyl ether(SCGE)with high reactivity and low viscosity was used as diluent to modify the curing system of bisphenol type epoxy resin(E-51)and methylhexahydrophthalic anhydride( Me HHPA).The influence of SCGE amount on the structure and properties of the cured epoxy resins were investigated by the viscosity test,FT-IR,mechanical performance testing,dynamic mechanical analysis(DMA)and scanning electron microscopy(SEM).The results showed that the SCGE had significant diluting effect to E-51. The impact strength and tensile strength of cured epoxy resins were evidently improved. When adding 15 wt % SCGE,the impact strength of cured epoxy resins reached the maximum value of 17.53 k J/m^2. When the content of SCGE was 10 wt%,the tensile strength of cured epoxy resins reached the maximum value of 73. 63 MPa. The SCGE had significant toughening effect. Whereas,the glass transition temperature(Tg)was gradually decreased with the increasing of SCGE content.
