以酚醛树脂与环氧树脂为基体树脂,采用耐热树脂与改性丙烯酸酯化合物进行改性,制得一种真空压力浸渍树脂SD1150,对其黏度、凝胶时间、电气性能、真空压力浸渍处理绝缘线棒的电气性能、耐热性以及毒性进行研究.结果表明:SD1150是一种电气性能优异、耐热性好、毒性小的环保型浸渍树脂.
Using phenolic resin and epoxy resin as matrix resin, which was modified by heat resistance resin and modified acrylic ester compound, we prepared a vacuum pressure impregnating resin SD1150. The viscosity, gel time, electrical properties, heat resistance, and toxicity of the SD1150 and the electrical properties of insulated copper bars after vacuum pressure impregnating treatment were studied. The results indicate that the SD1150 is a kind of environment-friendly impregnating resin with excellent electrical properties, good heat resistance, and low toxicity.
