摘要
将合成的双酚A型苯并噁嗪(BOZ)作为成炭协效剂与二乙基次膦酸铝(ADP)复配应用于阻燃聚酰胺6(PA6),熔融共混制备了阻燃PA6复合材料.通过UL94阻燃等级、极限氧指数(LOI)、锥形量热(Cone)、扫描电镜(SEM)以及热分析(TG/DTG)等研究了复合材料的协同阻燃性能及作用机制.结果表明:BOZ和ADP在阻燃PA6具有良好的协同阻燃效应.添加0.3%BOZ和9.7%ADP时,PA6/ADP/BOZ复合材料的垂直燃烧达到UL94 V-0级,LOI达到了31.0%,拉伸强度、弯曲强度分别为74.6和109.6 MPa.
The synthesized bisphenol A benzoxazine(BOZ) was used as a carbon synergist with diethyl-phosphate aluminum(ADP) for flame retardant PA6, and the flame retardant PA6 composite was prepared by melt blending. Their synergistic flame retardant effects and mechanism were investigated by means of UL94 vertical burning rating, limiting oxygen index(LOI), cone calorimeter test(Cone), scanning electron microscope(SEM) and thermogravimetric analysis(TG). The results showed that BOZ and ADP had good synergistic flame retardancy in PA6. When 0.3% BOZ and 9.7% ADP were added(based on the total mass), the PA6/ADP/BOZ composites reached UL94 V-0 rating, LOI reached 31.0%, and the tensile strength and bending strength of the composite were 74.6 and 109.6 MPa respectively.
