Glasses are generally composed of spectacle lenses and spectacle frames, and spectacle lenses play a role of protecting the eyes from dust or sunlight, while spectacle lenses serve as a means for fixing and wearing spectacle lenses. do.

In the case of spectacle lenses, spectacle lenses having high strength and high elasticity have been developed so as to be suitable for use in military or work due to the continuous development of the material, and are used as bulletproof goggles or work goggles.

Eyeglass frames are manufactured using metal materials or synthetic polymer resins, and metal materials are manufactured using alloy materials such as nickel alloys, so they have good durability and texture and excellent abrasion resistance, but they are poor in moldability and difficult to implement various designs. There is a problem that it weighs a lot when worn.

On the other hand, since the eyeglass frame made of synthetic resin is usually manufactured through an injection mold, it has the advantage of excellent moldability, realization of various designs and colors, and easy mass production.

As the use of spectacle frames made of synthetic resin (plastic) increases, it has functional effects such as suppressing the occurrence of bacteria on the skin contact surface, promoting blood circulation, reducing eye fatigue, and activating cerebral biorhythms. Many techniques for viewing have been proposed.

As an example of this technology, conventionally, a method of forming a film layer by coating a bioceramic on the surface has been used, and methods for manufacturing antibacterial eyeglass frames by injection molding by mixing nanometal components having antibacterial activity such as silver and copper have been developed. Has been used.

However, the method of surface coating bioceramic has a problem of losing functionality if the bioceramic film layer is peeled off or damaged due to repeated wear, and the injection molding method by mixing nano metal components has poor compatibility with polymer resins. There is a problem and the dispersion is not even, so there is a problem that it is difficult to uniformly exert the antimicrobial properties of the entire spectacle frame due to intensive agglomeration in only a part of the polymer resin. Therefore, it is necessary to develop a technology to solve this problem.

Nano metal ions and inorganic carriers are added to water (in water) and stirred so that the nano metal ions are supported on the inorganic carrier.

The fraudulent nano-metal ions may be selected from silver, copper, zinc, tin, lead, bismuth, cadmium, chromium, and thallium, and the inorganic carrier may be selected from zeolite, calcium phosphate, and zirconium phosphate.

At this time, the nano metal ions may be collected in the porous structure formed on the inorganic carrier to form a carrier carrying the metal ions. The carrier formed in this way improves the dispersibility of nano metal ions so that uniform antimicrobial properties are exhibited as a whole when applied to an eyeglass frame.

Meanwhile, the nano metal ions may be separated after being supported on the inorganic carrier. When such ion separation occurs, uniform antimicrobial performance due to the inorganic carrier may be hindered, so it is necessary to suppress ion separation.

Therefore, in the present invention, it is necessary to coat the surface of the inorganic carrier.

2. Antimicrobial powder manufacturing

The surface coating of the inorganic carrier as described above uses calcium silicate and microsilica.

First, the obtained inorganic carrier carrying the nano-metal ions is added into an acidic aqueous solution. As the acidic aqueous solution, an aqueous aluminum chloride solution may be used, and the pH is adjusted to a neutral region again while the inorganic carrier is dispersed in the acidic aqueous solution. At this time, in order to adjust the pH to the neutral region, it is preferable to use an aqueous alkaline solution, and for example, an aqueous sodium hydroxide solution may be used.

Thereafter, calcium silicate and microsilica are added and stirred to form a film made of a silicic acid component on the surface of the inorganic carrier.

The calcium silicate is a liquid glass component, and the microsilica is a silica particle diameter having a particle diameter of 0.1 to 20 μm, and they form a coating layer on the surface of an inorganic carrier to prevent separation of nano metal ions.

In this case, the thickness of the coating layer is preferably about 0.1 ~ 20㎛ thickness.

After forming the coating layer on the inorganic carrier as described above, the powder component is allowed to stand at room temperature to precipitate the powder component, and the precipitate is collected by filtration, then purified several times with purified water and dried to obtain an antibacterial powder.

The cellulose ester system is excellent in adaptability to skin and elasticity, and specifically, cellulose acetate, cellulose acetate butyrate, or cellulose acetate propinate may be used. In the case of the ABS-based resin, it is suitable for use for eyeglass frames because of its excellent strength and elasticity.

In addition, as the additive, one kind of additives such as fillers, antioxidants, heat stabilizers, light stabilizers, ultraviolet absorbers, plasticizers, antistatic agents, flame retardants, release agents, foaming agents, nucleating agents, lubricants, anti-static agents, anti-drip agents, and metal deactivators.

In the injection molding process, a pigment may be added to produce a colored spectacle frame, or a transparent colorless spectacle frame may be manufactured without a pigment.

In addition, in order to improve the durability and strength of the spectacle frame, the present inventor may injection mold using a fiber composite reinforcing material proposed in a separate patent (Korean Patent No. 10-1317591) as a core material.

The spectacle frame manufactured by the above method has the advantage of not only less discoloration and deterioration, but also excellent processability, and can be manufactured and utilized in various designs and colors.

(2) Coating method
