【摘要】 以氢化双酚A和环氧氯丙烷为原料,在催化剂的作用下按照先醚化后环化的技术路线成功合成出了氢化双酚A型环氧树脂.采用红外光谱、核磁共振波谱表征其结构,并与已知产品进行对比,证明了合成产物结构的准确性和可靠性;通过普通双酚A型环氧树脂与合成出的氢化双酚A型环氧树脂的紫外吸收对比,发现氢化双酚A型环氧树脂对紫外光吸收能力很弱,是一种优异的耐光老化树脂.基本性能测试表明,合成出的氢化双酚A型环氧树脂的性能与BASF公司产品接近.更多还原

【Abstract】 An anti-ultraviolet radiation epoxy resin is prepared from hydrogenated bisphenol-A and epichlorohydrin under the effect of catalyst.Its elementary mechanism and synthetic route are explained.The structure and component of the epoxy resin are analyzed and characterized in detail by FTIR and 1H-NMR spectra.It is shown that the structure of the epoxy resin is proper and trusty.The ultraviolet shielding ability of the product is tested through UV spectrophotometer,and the result shows that compared with bisphenol-A epoxy resin,the hydrogenated bisphenol-A epoxy resin has very little absorption of ultraviolet,so it is a excellent anti-Ultraviolet epoxy resin.The performance of the hydrogenated bisphenol-A epoxy resin is close to that of the product of BASF Co.Ltd of Germany.更多还原
