抗菌抗静电型PP/CB复合材料的制备及性能研究
|
摘要
通过熔融共混制备抗菌及抗静电型PP/CB复合材料,研究了抗菌剂(美灵康乐)、抗静电剂(导电炭黑)对PP/CB复合材料的抗菌性能、电性能和力学性能的影响。结果表明,质量分数为0.8%抗菌剂在PP基体中分散均匀,力学性能基体不受影响,对金黄色葡萄球菌、大肠埃希氏菌等的抗菌率都在80%以上,表现出良好的抗菌性能。少量导电炭黑对PP/CB复合材料的力学性能具有一定的补强作用。当导电炭黑的质量含量为30%时,PP/CB复合材料的表面电阻降低至108Ω以下,达到了抗静电材料的要求。
The antibacterial and antistatic PP/CB composites were prepared by melt blending.The effects of antimicrobial agent(MILLION KILLER)and antistatic agent(conductive carbon black)on the antibacterial properties,electrical properties and mechanical properties of PP composites were investigated.The results showed that:when the content of antimicrobial agent was 0.8%,it could be uniformly dispersed in the PP matrix and the physical properties of PP/CB composites remained stable.And the antibacterial rates of Staphylococcus aureus and Escherichia coli bacteria were more than 80%which meant the good antibacterial properties of PP/CB composites.A small amount of conductive carbon black had a reinforcing effect on the mechanical properties of PP/CB composites.When the content of the conductive carbon black was30%,the surface resistance of PP/CB composite reduced to less than 108Ω.
