摘要:
采用热熔法制备抗菌防霉预浸料,并对其力学性能、燃烧产物、阻燃性能以及抗菌防霉性能进行了系统的评价。结果表明:复合材料面板的燃烧产物中CO、HF、HCl、NOx、SO2、HCN等6种毒性气体含量均远远低于标准;阻燃性能优异,无火焰穿透,无熔融物滴落,且平均自熄时间大都为0 s;防霉性能均为0级;抗菌性能随着抗菌防霉剂含量的增大而增强,其中当抗菌防霉剂含量≥2%时,能够满足抗菌性能要求。由于力学性能随着抗菌防霉剂的添加呈下降趋势,为了兼顾力学性能与抗菌性能,创新设计不同抗菌防霉剂分布而保持平均含量不变的复合材料面板,对比抗菌性能结果发现将抗菌防霉剂含量高的预浸料分布在表面时得到的复合材料面板拥有最优异的抗菌性能,成功实现结构生物安全一体化。

Abstract:
Antibacterial and mildew-proof prepregs were prepared by hot melt impregnation.Their mechanical properties,production of combustion,flame retardment,antibacterial and mildew-proof properties were systematicly studied.The results show that the concentration of composite faceplates’ production of combustion(CO,HF,HCl,NOx,SO2,HCN) is far below the standard value. It has the outstanding flame retardment property without flame penetration and drippage of melt,since their self-extinguishment time are all 0 s.The mildew-proof level of all the samples is 0 level.Along with the concentration of additives increasing, antibacterial property became stronger while mechanical properties were weaker.When the concentration was higher than 2%,it can meet the standard requirement.To solve the contradiction between mechanical and antibacterial property,faceplates with the same average content of additives while different distributions are designed.Those whose additives distributed on the surface exbihit the best anti-bacterial property.The structural biosafety integration of materials has been successfully achieved.
