亚克力人造石废粉对ABS热分解过程的影响

Effects of Yakeli Artificial Stone WastePoweron Thermal Decomposition Process ofABS

以亚克力人造石废粉为填料,苯乙烯-马来酸酐共聚物(SMA)为相容剂,采用熔融共混法制备了ABS/亚克力人造石废粉复合材料,通过热分析(TGA)测试,研究了相容剂SMA、亚克力人造石废粉用量对复合材料热分解过程的影响。结果表明,相容剂SMA的加入使得ABS与亚克力人造石废粉之间的相容性变好,ABS与亚克力人造石废粉间联结更加紧密,较好抑制了ABS的热解反应;亚克力人造石废粉中的Al(OH)3属于强脱水性物质,可加速ABS碳化;起始分解温度及最大热分解速率温度均随亚克力人造石废粉用量的增加而增大,当亚克力人造石废粉用量为20%时达到最大值,较纯ABS分别提高了6.3℃和5.3℃。

ABS/yakeli artificial stone wastepower composites were prepared by melt blending which filled with styrene-maleic anhydride copolymer as compatibilizer,the influence of compatibilizer and content ofyakeli artificial stone wastepower on thermal decomposition process was investigated by dynamic thermogravimetric analysis.The results demonstrated that compatibilizer SMA could improve the interfacial compatibility of theABS/yakeli artificial stone wastepower composites,thermal decomposition of ABS was suppressed effectively.Al(OH)3 of yakeli artificial stone wastepower belongs to strong dehydration material,accelerated carbonization of ABS.The initial decomposition temperature and maximal thermal decomposition rate temperature increased with increasing contents of yakeli artificial stone wastepower.The initial decomposition temperature and maximal thermal decomposition rate temperature improves 6.3℃and 5.3℃respectively when contents was 20%.
