摘要
研究十溴二苯乙烷(DBDPE)/三氧化二锑(Sb2O3)复合阻燃丁苯橡胶(SBR)的协同效应。结果表明:DBDPE/Sb2O3协同阻燃SBR,氧指数可达26.5%,UL-94达V-1级,热释放速率大幅降低,有一定协同效应;空气气氛下,DBDPE和Sb2O3相互促进成炭,且形成的炭层在800℃不分解。
The synergistic flame retardant effect of DBDPE and Sbz03 on SBR composite was in- vestigated. The experimental results showed that with both DBDPE and SbzO3 flame retardants the oxygen index of SBR increased to 26.5% ,the composite reached the UL-94 V-1 rating,and the heat release rate decreased significantly. In air atmosphere, DBDPE and Sb203 could promote the carbon generation and the formed carbon layer did not decompose at 800 ℃.
