腰果酚基环氧磷酸酯对E-51/IPDA环氧树脂体系性能的影响
Effects of Cardanol-based Epoxidized Phosphate on the Properties of E-51/IPDA Epoxy Resin System
摘要
Abstract
A cardanol-based phosphate epoxidized( CGEP) was synthesized using cardanol. as feedstock. The curing system of bisphenol A epoxy resin(E-51) and isophorone diamine(IPDA) was modified by CGEP in different mass ratios. The influences of CGEP on the viscosity of E-51 and on the properties of cured epoxy resins were investigated. The microstructure of fracture surface of cured epoxy resins was characterized by scanning electron microscope( SEM) . It was found that CGEP has significantly diluted the E-51 and involved in the curing reaction of epoxy resin. When the content of CGEP was 15 wt% with respect to E-51, the impact strength of cured epoxy resins reached the maximum 22. 06 kJ/m2 . When the content of CGEP was 20% with respect to E-51, the tensile strength and bending strength of cured epoxy resins reached the maximum 96. 19 Mpa and 99. 70 Mpa, respectively. With the increase of the amount of CGEP from 0% to 25% , the glass transition temperature ( Tg ) of the cured product decreased from 144. 82℃ to 119. 10℃, while the oxygen index increased from 19. 0 to 23. 0. SEM analysis showed that the toughness of cured epoxy resins improved obviously.关键词
