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,NO_x,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.
