摘要
对蛭石粉体填充PA66进行了试验研究,考察了经不同偶联剂表面处理的蛭石粉体及其不同填充用量对PA66性能的影响。结果表明,钛酸酯和硬脂酸混合处理的蛭石PA66复合材料的力学性能最佳,当加入26%混合处理的蛭石粉体时,复合材料的拉伸强度、弹性模量、弯曲模量分别提高9%、116%和55%。
This paper studied PA66 performance affected by vermiculite powder＇S surface treatment with different coupling agents and filling amount when vermiculite powder filled PA66. The results showed that the mechanical properties of vermiculite PA66 composite materials were optimal when vermiculite powder filler content was 26% and treated by the mixture of titanate and stearic acid. The tensile strength, elastic modulus and flexural modulus of composite materials increased respectively 9%, 116% and 55%.
