摘要
采用不同稠度的硅油与低分子液态环氧树脂和聚醚共混改性的方法,制备了有机硅改性聚醚环氧树脂。同时,采用该有机硅改性聚醚环氧树脂为密封剂的基体树脂,并向其中加入固化剂、阻燃剂、促进剂、脱模剂以及增强填料等制备了电缆接线盒密封防水平衡剂,该密封剂在固化过程中不放热也不吸热,且固化过程中无收缩,固化物具有良好的弹性、电绝缘性、耐高低温性、耐老化性和耐盐水性以及减震防尘性能。
The organic silicon modified polyether epoxy resin was prepared with using silicon oil which had different consistencies, epoxy resin and polyether by the method of blending modification. Then the water-repellent sealant for the cable connection box was prepared with using this organic silicon modified polyether epoxy resin as the matrix resin, and adding curing agent,？flame retardant, accelerant,？mold discharging agent and fillers. The sealant would not release heat nor absorb heat in the curing process, and had little shrinking, the cured product had good elasticity, electric insulativity, high temperatures-resistance, aging-resistance, salt water resistance, shock-resistance and dust free performence.
