摘要
利用纳米氢氧化铝(nano⁃ATH)和包覆红磷(ERP)对丙烯腈-丁二烯-苯乙烯共聚物(ABS)进行阻燃,研究了nano⁃ATH和ERP对ABS复合材料的力学性能和火焰阻燃性能的影响;分析了ABS复合材料燃烧后的炭层形貌。结果表明,随着nano⁃ATH和ERP含量的增加,复合材料的阻燃性能和弯曲性能不断提高,冲击性能逐渐降低,拉伸性能呈先增加后降低的趋势。nano⁃ATH和ERP之间的协效阻燃作用良好,当ABS为70%、nano⁃ATH为15%、ERP为15%时,ABS复合材料的拉伸强度达到34.85 MPa,弯曲模量可达到2472 MPa,水平燃烧等级达到FH-1级,垂直燃烧等级达到FV⁃0级,热释放速率峰值、平均热释放速率及总的热释放量分别为250.25 kW/m^(2)、88.99 kW/m^(2)、83.73 MJ/m^(2),燃烧后形成的炭层比较完整,但是该复合材料的冲击性能有待提高。
Flame retardancy acrylonitrile⁃butadiene⁃styrene copolymer(ABS)was prepared by melt blending ABS,nano aluminum hydroxide(nano⁃ATH),and encapsulated red phosphorus(ERP).The influences of nano⁃ATH,and ERP on mechanical properties,and flame retardance of ABS composite were studied.The morphologies of char layers were characterized through SEM.The results showed that the flame retardance and flexural properties of the composite both increased,the impact property decreased,and the tensile property increased,then decreased with the nano⁃ATH and ERP content.The synergistic effect of flame retardance between nano⁃ATH and ERP was better.The tensile strength and flexural modulus of the ABS composite reached respectively 34.85 MPa and 2472 MPa when the content of the ABS,nano⁃ATH,and ERP was 70%,15%and 15%,respectively.The horizontal combustion and vertical combustion rating of the ABS composite reach respectively FH⁃1 and FV⁃0.The peak value of heat release rate,average value of heat release rate,and total heat release was 250.25 kW/m^(2),88.99 kW/m^(2),83.73 MJ/m^(2),respectively.The intact char layer was formed after combustion,its impact property needs to be improved.
