Antibacterial polymethyl methacrylate and preparation method thereof

The invention discloses an antibacterial polymethyl methacrylate and a preparation method thereof. Mesoporous silica can be taken as a carrier, nano silver can be generated on the surface and holes ofthe mesoporous silica in situ, so that mesoporous silica particles carrying the nano silver can be obtained, and the phenomenon of nano silver agglomeration can be effectively solved; uniform dispersing in a polymethyl methacrylate substrate can be achieved, and as the addition of the nano silver particles, the polymethyl methacrylate can have good broad-spectrum antibacterial, powerful bactericidal and lasting antibacterial effects; and a cross-linked network can be formed by connecting modified silica composite particles and polymers through chemical bonds, and therefore, interfacial forcecan be enhanced, and the thermostability of the polymethyl methacrylate can be increased. 本发明公开了种抗菌有机玻璃及其制备方法，将介孔二氧化硅作为载体，并在介孔二氧化硅表面和孔道中原位生成纳米银，得到负载纳米银的介孔二氧化硅粒子，有效解决了纳米银团聚的现象，均匀的分散在有机玻璃基底中，同时纳米银粒子的加入，使有机玻璃具有良好的广谱抗菌、强效杀菌、抗菌持久效果
