Abstract: A new inorganic antibacterial silica gel containing zinc and yttrium ions was prepared by a sol-gel method,using sodium bicarbonate and sodium silicate as raw materials.The better preparation conditions were obtained by controlling single factor variable experiments:the concentration of zinc ion 0.8mol/L,the rare earth yttrium concentration 0.005mol/L and reaction time 1h.The material as synthesized was characterized by the particle size analyzer,FT-IR,XRD,SEM and laser particle size analyzer.The antibacterial properties of products were detected by antibacterial experiment (spread plate method,strains with e.coli bacteria).The results showed that zinc and yttrium ions had no effect on the molecular structure and chemical bond of silica gel.The particle size of silica gel was minimum with a narrow size distribution,and its structure was fluffy and porous.The products worked well on Escherichia coli disinfection,the bacteriostasis rate can reach above 84%.The Zn-antibacterial silica gel was added into the silicone rubber,and found that when the addition amount was 0.35%,they showed better capability of not only the intrinsic performance but also the antibacterial character.
