摘要
由羟基香茅醛合成了多元醇3,7-二甲基-2,2-二羟甲基-1,6辛二醇并由它合成了螺环原碳酸酯单体3、9—二羟甲基—二(6—甲基—5—羟基)—2—庚基—1,5,7,11四氧杂螺环[5、5]十一烷单体以及它的预聚体,并用其来改性酚醛环氧树脂F-44.利用红外光谱对多元醇,螺环单体及预聚体进行了表征.依据DSC测试结果确定了固化温度;利用万能材料实验机测试了固化改性酚醛环氧树脂的力学性能.实验表明,预聚体的加入提高了酚醛环氧树脂的剪切强度和拉伸强度.
An expansion monomer 3,9-dihydroxymethyl-di(6-methyl-5-hydroxyl)-2-heptanone-1,5,7, 11-tetraoxaspiro [5,5]undecane has been synthesized and used to modify the properties of the phenolic epoxy-F44. The mechanical properties of the modified phenolic epoxy resin matrix were measured. It was found that the adhesive tensile and shear strength of the modified phenolic epoxy resin had been increased.
