环氧树脂改性国内外研究现状

Research status of epoxy resin modification at home and abroad

环氧树脂是一种历史悠久、用途广泛的热固性树脂材料,因其有优良的力学性能、介电性能和耐化学腐蚀性,可以作为工程塑料、层压材料、模压料、涂料等,被广泛应用于航空航天、车辆工程、军工等高技术领域。但是由于纯环氧树脂固化物普遍存在着脆性大、可燃等缺点,并且随着科技的发展,各个应用领域对材料性能的要求越来越高,因此对环氧树脂进行改性是其未来发展趋势之一。对近几年环氧树脂改性研究现状进行综述,其中包括不同类型固化剂改性EP,新型结构环氧树脂的制备,以及对环氧树脂合金体系和环氧树脂复合材料的研究,对改性效果进行详细阐述,讨论改性机理。

Epoxy resin is a thermosetting resin material with a long history and a wide range of applications.Because of its excellent mechanical properties, dielectric properties and chemical resistance, it can be used as engineering plastics, laminates, molding materials, coatings, etc.,and has been widely applied in the high-tech fields of aerospace, vehicle engineering, and military industry.However, because pure epoxy resin cured products have common shortcomings such as brittleness and flammability, and cannot meet the higher performance requirements with the development of science and technology, so the modification of epoxy resin is important in future development.This article reviewed the research status of epoxy resin modification in recent years, including different types of curing agents modified EP,preparation of new structural epoxy resins, as well as research on epoxy resin alloy systems and epoxy resin composite materials.The modification effect was elaborated and the modification mechanism was also discussed.
