THE BLENDING TREATMENT METHOD OF AGNO3 BY A CONTACT LENS WITH QUATERNARY AMMONIUM GROUP COPOLYMERIZATION

摘要

The present invention relates to a blending method of the silver nitrate on the contact lens by copolymerization of quaternary ammonium, in the present invention, the quaternary ammonium is excellent in anti-microbial as fungicides or protein remover solution to the general contact lens materials (Quaternary ammonium group) and the light according to permeability, as well as excellent in the transparency to light brown to appear directed to separate the chemical bonding that occurs easily due to the light provide a lens that has a strong antibacterial to be silver introduction of nanoscale stable physically than the conventional, HEMA ( hydroxy ethylmethacrylate), MMA (methylmetacrylate) , MA (methacrylate), NVP (N-vinyl-pyroridon) with an initiator and then mixing an appropriate amount of the oxidizing agent of AIBN (azobisisobuthylnitrile) 0.005% by weight of silver nitrate (AgNO ₃₎ and 1% by weight of 4 or less into the ammonium salt, and mixed well by 60-degree cone by copolymerization of quaternary ammonium, it characterized in that the polymerization is approximately one hour in the heat bath By blending processing of the silver nitrate method for tact lens, the antibacterial activity and will be useful for the inventors to be stabilized by blending the silver material with light permeability, as well as excellent in transparency and be available in the color lens is light brown color appears.
