| 摘 要： | 通过苯甲酸改性酚醛环氧树脂得到了含羟基的酚醛环氧树脂,再经固化剂甲苯二异氰酸酯三聚体和邻苯二甲酸酐固化后,得到了耐热的环氧聚氨酯复合涂层.通过改变苯甲酸改性酚醛环氧树脂的开环率,研究了在聚氨酯体系中引入酚醛环氧树脂的量对其耐热性能的影响.以傅里叶变换红外光谱研究了苯甲酸改性酚醛环氧树脂及其固化过程,以热重分析研究了酚醛...

| Abstract: | A hydroxy-containing novolac epoxy resin was obtained from bisphenol A epoxy resin after modification by benzoic acid,and then cured with toluene diisocyanate trimer and phthalic anhydride as curing agents to form a thermal resistant epoxy-polyurethane composite coating.The effect of the amount of novolac epoxy resin introduced to polyurethane system on the thermal resistance of coating was studied by changing the ring-opening rate of benzoic acid-modified novolac epoxy resin.The benzoic acidmodified novola... |
