Antibacterial spectacle lens and manufacturing process thereof

Abstract

The invention relates to the technical field of spectacle lenses, and in particular, relates to an antibacterial spectacle lens and a manufacturing process thereof. The antibacterial spectacle lens iscomposed of the following components in percentage by weight through extrusion and curing: 70 to 80 parts of allyl diglycol carbonate, 5 to 8 parts of polypropylene glycol, 2 to 3 parts of nano silicon dioxide, 0.5 to 1 part of silver ions, 0.5 to 1 part of zinc ions, 5 to 8 parts of an organic solvent and 2 to 4 parts of glass microparticles. The manufacturing process of the antibacterial spectacle lens comprises the following operation steps: step 1, weighing all the components of any one of the antibacterial spectacle lenses in claims 1-2 in percentage by weight, adding the weighed components into a grinding tank, and stirring and grinding; step 2, adding the components stirred and ground in the step 1 into a double-screw extruder, and carrying out melt extrusion; and step 3, carryingout injection molding through a mold. The spectacle lens provided by the invention has a lasting antibacterial function and strong light transmission.

Description

technical field [0001] The invention relates to the technical field of spectacle lenses, in particular to an antibacterial spectacle lens and a manufacturing process thereof. Background technique [0002] Resin spectacle lens is an organic material with a three-dimensional network structure inside. The intermolecular structure is relatively loose, and there is space for relative displacement between molecular chains. The light transmittance is as high as 84%-90%, and the light transmittance is relatively good. , At the same time, the impact resistance is relatively strong, but the general resin lens is not antibacterial, and after adding some wear-resistant or antibacterial agents, its light transmission will be greatly affected. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an antibacterial spectacle lens with durable antibacterial function and strong light transmission and its manufacturing process.
