【摘要】 虽然环氧树脂因具有优异的粘接性能和力学性能等而被广泛应用,但其耐热性较差、脆性大等缺陷限制了其在高性能领域中的应用。为此综述了有机硅树脂、聚氨酯、聚酰亚胺、刚性无机填料、纳米粒子及腰果壳油改性环氧树脂的最新研究进展,对各种改性环氧树脂的优缺点和改性机理进行了探讨,并对其应用前景进行了展望。更多还原

【Abstract】 Epoxy resin was widely used in many fields as it had excellent bonding power and mechanical properties. But its poor thermal resistance and brittleness limited its use in the more demanding fields. Recent advances in the modification of epoxy resin were reviewed. The present status of epoxy resin modified by organic silicon resin, polyurethane, polyimide, rigid inorganic filler, nanometer particle and cashew nut shell liquid were introduced in detail. The advantages, disadvantages of modified epoxy resin and the modification mentioned above were discussed, and its application was also prospected.更多还原
