In general, glasses are used for vision correction, so they play a very important function for the wearer, and a wide variety of products are manufactured in terms of materials and designs.

The brief description of the most basic structure of the glasses consists of a lens for correcting vision, a rim fixing the lens and a pair of rims connecting the pair of rims, and a hinge portion for making the leg foldable. In order to improve, it is common to form nose pads on the rim and the bridge, and to install an additional device such as an elastic device on the hinge part or the eyeglass leg.

In addition, a part of the structure of the spectacles except for the lens is generally referred to as eyeglasses. The most representative materials for manufacturing such spectacle frames include metal and synthetic resin, and there are differences in the manufacturing method and manufacturing process of the product due to the characteristics of the two materials.

In addition, in the case of the metal material is mainly a mass production method using a press, and in the case of synthetic resin material, a mass production method using injection molding is used.

Here, in the case of the synthetic resin spectacle frame produced by the injection molding method, because the rim and the bridge or the rim and the bridge and the nose butt is integrally framed can be produced in one process using an injection molding machine with an advantage of excellent productivity Due to the situation that various types of synthetic resin eyeglass frames are manufactured by injection molding.

In addition, eyeglass frames can be classified into metal frames and nonmetal frames, and mixed frames mixed with metals and nonmetals, based on materials. In the case of metal frames, it is common to use different materials for each part of the frames.

Meanwhile, with increasing interest in health, functional glasses have been developed in accordance with the trend of modern people who prefer functional glasses, and according to such a situation, various components are coated on each component of the glasses through a coating method.

In addition, the function of the coating material is known to have the effect of far-infrared generation and vision protection, facial blood circulation, and eye fatigue.

However, such a coating method has a problem that acts as a cause of reducing the life of the glasses while the far-infrared material is peeled off because the coating material is peeled off when using the glasses for a long time.

In addition, there is a problem that inflammation occurs that can cause skin diseases in temples and nose, such as contact with the skin if you continue to wear glasses in a situation where the coating material is dropped.

The present invention has been made to solve the above problems, to provide a master batch chip in which illite is uniformly uniformly mixed in a high concentration, and mixing the master batch chip and the general polymer resin chip containing no illite again. The purpose of the present invention is to provide a method for manufacturing a spectacle frame using a master batch chip containing an illite consisting of the step of obtaining the spectacle frame injection material and then injecting the spectacle frame injection material into an injection molding machine.

In order to achieve the above object, the present invention is to crush the crushed illite raw material into a crusher to a 1000 ~ 2000 mesh pulverized in the pulverization chamber to the step of introducing into the cyclone through a doctor, and the movement to the cyclone Filtering a raw material using an ultrafine filter, supplying the filtered raw material to a precipitation tank filled with water to form a gel, and then supplying a precipitant, a neutralizing agent and water, and then precipitating the precipitated raw material. The precipitate was put into a drier and dried at a temperature of 200 to 250 ° C. for 20 minutes to obtain pure illite powder, and 20 wt% of the illite powder was any one of polypropylene resin, polyethylene resin, olefin resin and polyester resin. 70% by weight of, and 10% by weight of the paraffin wax integrally mixed, and then melted to form a masterbatch chip through an extruder The system, 2 to 3% by weight of the master batch chip and 97 to 98% by weight of the general polymer resin chip containing no elite are added to a mixing tank, and then mixed to obtain an eyeglass frame injection material; and the eyeglass frame injection material The present invention relates to a method for manufacturing a spectacle frame using a masterbatch chip containing an illite which is injected into an injection molding machine, and the step of injection molding the spectacle frame, the spectacles, and the nose support.

In the present invention, since the illite powder is contained in the masterbatch chip, the mixture is mixed with the synthetic resin powder for molding the spectacle frame and formed into the spectacle frame through an injection molding machine, thereby releasing far-infrared rays and anions in the spectacle frame, thereby maintaining new metabolism of eye cells. There are features that can be promoted.

In addition, the spectacle frame of the present invention has an antimicrobial effect and can effectively block harmful electromagnetic waves while significantly reducing bacteria around the eyeball.
