Problems solved by technology

[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. , while 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

Embodiment Construction

[0014] An antibacterial spectacle lens, which is formed by extrusion and solidification of the following components by weight percentage: 70-80 parts of propylene glycol diethylene glycol carbonate, 5-8 parts of polypropylene glycol, 2-3 parts of nano silicon dioxide, silver 0.5-1 parts of ions, 0.5-1 parts of zinc ions, 5-8 parts of organic solvents, 2-4 parts of glass particles. Polypropylene glycol is a plasticizer, and nano-silica can further increase the strength of the lens.

[0015] Optimized, the following components are extruded and solidified by weight percentage, 75 parts of propylene glycol diethylene glycol carbonate, 6.5 parts of polypropylene glycol, 2.5 parts of nano-silicon dioxide, 0.8 parts of silver ions, 0.8 parts of zinc ions, organic 6.5 parts of solvent, 3 parts of glass particles, using this component to process spectacle lenses, the antibacterial effect, the light transmittance of the lens and the cost performance are higher.

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.
