双酚F环氧树脂的改性研究

Study on Modification of Bisphenol Formaldehyde Epoxy Resin

合成了双酚F/间苯二酚共聚型环氧树脂、二甲基二酚羟基有机烷氧基硅烷,并考察了双酚F/间苯二酚共聚型环氧树脂的性能以及不同二甲基二酚羟基有机烷氧基硅烷用量对双酚F环氧树脂固化物性能的影响。结果发现:改性后的树脂粘度降低,其固化物的耐热性提高,力学性能得到显著改善。

[Abstract] In this thesis, bisphenol formaldehyde （BPF）/resorcin copolymerized epoxy resin and 3, 3＇-dihydroxyldiphenoxydimethyl silieane were synthesized. The property of the BPF/resorcin eopolymerized epoxy resin and the effect of different dosage of 3,3 ＇-dihydroxyldiphenoxydimethyl silieane on the capability of condensate of BPF epoxy resin were investigated. The results suggested that modified epoxy resin had better heat-resistance and mechanics capability as well as lower viscosity.
