The invention discloses a method for preparing a silver-based inorganic antibacterial material. By modifying a methacrylamide graft knitted fabric by maleic anhydride, by virtue of double effects suchas adsorption and complexation of amino and double bond rich electrons on silver ions, adsorption of the silver ion is enhanced, and the loss of lots of nano-silver caused by washing of the knitted fabric is avoided. Moreover, by virtue of the reduction effect of the amino and double bond rich electrons on the silver ions, the negative ions are reduced into nano silver, the independent nano silver reduction step is reduced, and the efficiency is improved. Meanwhile, by virtue of the double effects such as adsorption and complexation of the amino and double bond rich electrons on silver ions,migration of the silver ion in the steaming reduction process is effectively controlled, gathering of the nano silver is effectively controlled, and the antibacterial effect is improved. 发明公开了一种银系无机抗菌材料的制备方法，通过马来酸酐对甲基丙烯酰胺接枝针织物
