Probed the effect of the content of guanylurea phosphate and the soaking time on flame retardation, at the same time the treated insulated paper was studied by thermal analysis. 考察了阻燃剂磷酸脒基脲浓度、浸渍处理时间对阻燃效果的影响,并研究了绝缘纸经阻燃处理后热降解参数、剩炭率、击穿电压的变化情况。
The char yield of insulated paper treated by guanylurea phosphate is 31.73%. The puncturing voltage of insulated paper treated by guanylurea phosphate decreases faintly. 绝缘纸剩炭率升高到31.73%,击穿电压稍有下降。
The char yield of insulated paper treated by boric acid or guanylurea phosphate is 18.92%, 30.79% separately; 硼酸处理的绝缘纸剩炭率升高到18.92%,磷酸脒基脲处理的升高到30.79%;
