采用3，4-环氧环己基甲基-3，4-环氧环己基甲酸酯（2010P）作为N，N，N′，N′-四环氧丙基-4，4′-二氨基二苯甲烷环氧树脂（AG-80）／六氢苯酐（HHPA）固化体系的稀释剂。通过粘度、拉伸、高温剪切、示差扫描量热法（ DSC）以及高倍显微镜等技术手段及方法，考察稀释剂含量对环氧树脂的粘度、力学性能和热性能的影响，研究了稀释剂与环氧树脂之间的相互作用。结果表明，2010 P可以显著提高树脂的流动性。随着2010 P含量的增加，体系的拉伸强度会呈现先上升后下降的趋势，在质量分数25％时达到最大值。 DSC结果显示，2010 P的加入会降低AG-80的玻璃化转变温度，但适量的加入可以进一步提高AG-80环氧树脂在高温条件下的粘接性能。当2010 P的质量分数为30％时，树脂在200℃的剪切强度可达到13.78 MPa。
3,4-Epoxycyclohexylmethyl-3,4-epoxycyclohexanecarboxylate (2010P) was adopted as the diluent of 4,4′-methylenebis(N,N-diglycidylaniline) epoxy(AG-80)/Hexahydrophthalic anhydride (HHPA) curing system.Via different testing methods such as viscosity , tensile, high temperature shearing test , differential scanning calorimetry ( DSC) , and high-power microscope , the effect of diluent on the viscosity , mechanical performances , and thermal properties of epoxy resin were investigated , and the interaction of diluent and epoxy resin was studied , respectively .2010 P was found to improve the fluidity of resin markedly .With increase of 2010 P mass fraction , the tensile strength increases at first and then decreases , and the maximum strength value appears at 25% mass fraction .DSC result shows that the glass transition temperature of AG-80 is reduced with the addition of 2010 P, nevertheless , the suitable content of 2010 P can further enhance the adhesion of AG-80 epoxy under high temperature .When mass fraction of 2010 P is 30%, the shear strength of resin is up to 13.78 MPa.
