【中英文摘要】 采用加入自制烯基阻燃树脂组份的新方法,合成了一种新型的H级阻燃无溶剂浸渍漆。研究了烯基阻燃树脂用量对绝缘漆综合性能,特别是阻燃性能的影响。分析比较了不同合成方法对产品粘温、耐热、电气等性能的影响。结果表明:该新型H级阻燃无溶剂浸渍漆具有阻燃性能好、电气绝缘性能佳、低温快固化的特点;当阻燃组份用量为不饱和聚酯量45%时综合性能最佳(氧指数为38)。
The vinyl-flame retardant resin and thermal-resistant UPR were mixed in styrene;a new class H flame retardant solventless impregnating varnish was prepared.The routine properties(such as heat resistance properties,electrical properties etc.)were introduced.The influences of the vinyl-flame-retardant resin content on flame-retardance properties of the impregnating varnish were discussed.The results showed that the impregnating varnish had good flame-retardant properties,and it could be cured quickly at lower temperature.When Vinyl-flame retardant resin/thermal-resistant UPwas45/100,the limiting oxygen index increased to38.
