Description

Liquid metal scissors and manufacture a way

As described above, the present invention relates to glasses, sunglasses or goggles, which are worn by people with bad eyes or worn for sun protection and fashion.

The glasses are divided into two types of corrective glasses and protective glasses according to the purpose of use, namely correcting glasses for correcting the non-visual acuity of the eyes, called corrective glasses, and the eye from the outside, namely ultraviolet rays and infrared rays. Strong visible light, wind, besides radiation,

Protective glasses are used to prevent foreign objects and medicines. Sunglasses and goggles fall into this category.

The corrective glasses include myopia, hyperopia, astigmatism, presbyopia, and the general protective glasses are sunglasses, and the special ones are dustproof, water, windproof, and snowproof provided with a barrier around the lens.

The present invention relates to a spectacle frame of glasses, sunglasses, goggles or the like to be organized by the liquid metal, more specifically, the spectacle frame is made of a liquid metal material of high hardness, very smooth surface and very good resilience and elasticity of the spectacle frame

The present invention relates to a liquid metal spectacle frame and a manufacturing method thereof.

Most commonly used spectacle frames are made of synthetic resin or light metal materials, and recently, spectacle frames of ceramic materials have been released and sold in Japan.

However, conventional spectacle frames made of synthetic resins or light metals are weak in strength, expensive, and difficult to manufacture, and deformation or breakage occurs due to physical impacts when using them.

Liquid metal used in the spectacle frame material of the present application has a rigid crystal structure, but the liquid metal is named as liquid metal because the arrangement of atoms is very free.

Liquid metal is lighter and 5 times stronger than iron, and it is incomparable with synthetic resins and light metals currently used as spectacle frames, and it is known to be free of corrosion unlike conventional metals. Depending on the user's requirements, the user can make the shape freely, and because it has no direction, it has excellent toughness, high strength and ductility, no magnetic anisotropy, and small electric resistance, so it is used in various materials.

In addition, conventional synthetic resin or light metal glasses material returns to the original crystal shape when cooled, whereas liquid metal maintains the amorphous atomic structure in the solid state, so there is no fragile part or nodular point, and thus the strength, elasticity and strength are very high.

In addition, it is possible to form a free shape like plastic at a high temperature and can be applied to various fields because the thickness is thin compared to the strength.

As such, the liquid metal may be used in various fields from industrial coatings to general products, sporting goods, and automobile parts, and in particular, it may be used as an electronic product case such as a mobile phone, a PDA, a TV, a notebook, and the like.

Normally, the process of making eyeglass frames is generally known. Metal eyeglass frames are manufactured in the form of eyeglass frames and then melted with metal to be photographed from a mold frame, and the eyeglass frames are polished smoothly with a grinder or the like.

Conventional spectacle frames have a very rough surface, which requires a complicated processing or post-treatment process, whereas the liquid metal of the present invention can obtain a smooth surface like the surface of glass without any additional process. It is an alloy of material with good conditions to be used as a material for eyeglass frames because it has many advantages such as good and plastic shape can be easily made.

Liquid metal of the present application is basically ingot-type raw materials such as zirconium copper, and all processes are vacuumed to prevent the molecular structure of the alloy from weakening.

In the state.

In addition, at what temperature the raw material melts through the high frequency equipment and the rolling process determines the quality of the liquid metal.

Processes and molding methods for liquid metal eyeglass frames include molding by a mold, which is the most commonly used method of injecting a liquid material into the mold in a liquid state and bulk-solidifying.

Products moved after the molding process are to be cut by a waterjet or laser when cutting diamond because the strength of the liquid metal is too strong to be processed, usually through a waterjet cutting machine or the surface is processed.

Liquid metal is not only tens of times stronger than iron, titanium, and magnesium, but also has no corrosion and can be molded precisely like plastic, and is considered as an advanced new material that can replace iron, titanium, and magnesium.

Liquid metal is usually made by mixing zirconium (40 ~ 45%) with a certain amount of titanium-nickel-copper, etc., and can be formed freely like plastic even in heat of about 600 ° C.

Most of all, when the product is made by casting (die-casting) method, other metal materials have rough surface of the parts, but liquid metal has a smooth outer surface like water, so it does not need any post-treatment at all.

The advantage of liquid metal is that it has very strong resilience and elastic strength, and is resistant to salts and other chemical reactions and can be manufactured in various forms.

In addition, there is an advantage that the effect of the amorphous structure, the high efficiency of energy transfer and the effect of absorbing vibration or shock.

It is a light metal that has high strength, excellent elasticity and corrosion resistance.

It is used as a structure for industry.

In addition, since the liquid metal is excellent in chemical resistance, it may be easily used in a reactor, a heat exchanger, or the like in the chemical industry, and thus is a very excellent material for the spectacle frame of the present invention.

Liquid metal spectacle frame used as a material of the spectacle frame of the present invention and its manufacturing method has a low thermal expansion or thermal conductivity coefficient as described above, the deformation is small during the manufacturing of the spectacle frame, liquid metal is excellent in corrosion resistance to the unpredictable of other materials, which is a liquid Oxidized liquid metal film formed on the metal surface is very strong and soft, not only has a large corrosion inhibitory effect, but also has high elasticity and a good property of instant regeneration even if the film is destroyed.

Currently, it is used as a spectacle frame material because iron is not used because of rust or corrosion. It mainly uses synthetic resin or light metal, and other metals such as gold, silver, copper, etc. are used by alloying or coating.

These frames should be made of materials with high strength. Current law does not place any restrictions on the material of the frames.

Since the glasses frame of the liquid metal material has a variety of such good properties, there is no fear of deformation or breakage even in the long term use and can prevent oxidation or contamination of the glasses frame.

The present invention relates to a method of manufacturing a functional eyeglass frame made of a liquid metal, which is light in weight, smooth in surface, and easy in manufacturing.

In general, liquid metal exhibits very strong corrosion resistance against nitric acid, chromic acid, and aqua residing acid under high temperature and high concentration conditions.

At high temperatures, corrosion occurs to non-oxidizing acids such as hydrochloric acid and sulfuric acid, but even in this case, when used with a slight oxidizing agent, corrosion resistance to such non-oxidizing acids is greatly improved.

In addition, liquid metal exhibits excellent corrosion resistance to boiling solutions and the like, and has stronger elasticity and strength than eyeglass frames of metals and ceramics used in the prior art, and liquid metal has a production cost of only one fifth of titanium. The material of the eyeglass frame will have the best conditions.

Conventional Glasses Frames (40)

Compared to the weight is very light, long time wearing the nose or ears are effective.

For example, the 14 Cm long liquid metal spectacle frame 40 weighs less than 10 g and does not have to be deformed or damaged as in the conventional spectacle frame 40 even if dropped on the floor during wearing.

As described above, the spectacle frame made of liquid metal is a new alloy material made of zirconium and mixed with titanium, nickel, copper, etc., and the liquid metal (liquid metal) is processed into the form of spectacle frame because the surface is smooth like liquid. coating

Liquid metal is usually made of zirconium (30-50% by weight) mixed with titanium-nickel-copper, etc., and can be freely formed and stretched like plastic even at a temperature of 600-800 ° C.

Most of all, when the parts are made by casting (die-casting) method, other metal materials have to be polished because the surface of the parts becomes rough during manufacturing, and the liquid metal of the present application is formed with a smooth skin like water and does not require any post-treatment.

In addition, the advantage of the liquid metal is not irritating to use in the human body, has a strong strength and elasticity, is resistant to salts and other chemical reactions emitted from the face and can be produced in various forms.

It is preferable to add 0.001 to 10% by weight of the liquid metal film is fixed on the surface of the spectacle frame, and to add a conventional metal spectacle frame to the coating tank, and to add a liquid metal binder to the current flowing to coat the current.

On the other hand, the dry coating of the present application is to go through the cleaning and rinsing process of the spectacle frame and to dry it, and then put the spectacle frame to the plasma tank to be dry-coated, and operate the power to perform a vacuum inside the tank and inert gas is injected at this time After attaching the target, the plasma is discharged, and then the liquid metal is coated on the spectacle frame.

The thickness of the liquid metal particles coated on the surface of the spectacle frame is preferably characterized in that the coating to 0.1 (nm) to 200㎛ (micro).

To be coated.

As described above, the present invention is a liquid metal (20) metal having a number of the above advantages in the manufacturing process of the spectacle frame of the present invention by stirring the liquid metal particles at 0.001 to 10% by weight relative to the total weight of the material of the spectacle frame and The particle size of the injected liquid metal has a size of 0.1 to 500 nm and the coating thickness of the eyeglass frame upon coating is characterized in that the coating film is formed on the eyeglass frame with a thickness of 0.1 nm to 200 ㎛ (micrometer), preferably the eyeglass frame body The nano-size liquid metal particles with respect to the total weight percent is characterized in that it further comprises a 0.001 to 10% by weight relative to the total weight% of the coating material of the coating portion of the spectacle frame.

The present invention follows a conventional coating method and because there are many types and methods of coating can not list all of them, a preferred embodiment of the present application to the first method of coating the liquid metal 20 is divided into electrolytic coating and electroless coating and electrolytic The coating uses electric current and the electroless coating is coated by chemical reactions without using electricity. In other words, coating means that metal ions receive electrons and are reduced to stick to a specific surface. The most common method is to coat with silver from the rectifier.

However, in the present invention that can not provide electricity to the substrate (substrate), the spectacle frame made of synthetic resin, ceramics, or material does not pass through electricity and cannot be coated by depositing a metal on it. In this case, the most electroless coating or binder is impregnated. To coat the superficial body.

There are usually two methods of electroless coating, one of which is ① reduction coating ② substitution coating method. The reduction coating method is a coating method in which metal is precipitated through reduction reaction. Activates the substrate surface to "+" state. When controlling it, you will use a surfactant component.

1) Catalyst: Palladium of colloidal component is attached to the surface of activated plastic.

2) Accelerator: (Palladium) It removes Sn (Tin) which is contained in Palladium colloid and protects Pd and makes Pd Metal precipitate on the surface of synthetic resin.

3) Electroless chemical coating: Contains copper ions, ethylenethiamine tetraacetic acid (EDTA), sodium hydroxide (NaOH), and formaldehyde. Pd plays the role of catalyst, when Na OH raises the pH to 11 or higher. Aldehyde has a strong reducing effect, and electrons are generated at this time, and these electrons flow to copper ions, and copper ions are deposited on the Pd catalyst and coated.

The second substitution coating is as follows.

Substitution coating method is caused by the difference of oxidation / reduction power. Representative materials of substitution coating are Ni / Au, Ag coating and electrodeposit Ni on metal surface using the same method as electroless chemical copper coating method.

Then, when immersed in a solution containing liquid metal ions, the liquid metal ions are stronger than nickel, and the liquid metal ions forcibly take away the electrons inside the nickel without leaving the nickel metal in place. The silver is oxidized to become an ion, and the liquid metal receives electrons from nickel and is reduced to be electrodeposition. In the above, the overall incorporation and coating process and composition of the spectacle frame have been described in detail. Liquid metal is extremely preferred for reinforcement, heat resistance, and durability, and the amount of mixing is preferably 0.001 to 10% by weight based on the total weight of the spectacle frame.

The density of the liquid metal is about five times that of conventional titanium steel, the modulus of elasticity (Modulus) is at least three times higher, and especially in the temperature range of -200 to 600, the specific strength (strength / specific gravity) is better than that of any industrial alloy. Since the metal 20 is very light, about 5 times as much as titanium, the weight of the spectacle frame 3 can be extremely light, and the thermal conductivity is also superior to that of titanium, and the thermal expansion is about 1/2 of that of titanium.

Particularly, the conventional metal frame made of metal is alloyed with iron or nickel, so there is a problem of rust or oxidation when used in the air, in a humid place, in the basement or at the seaside, and prevents rust or corrosion oxidation problems that may occur during distribution or storage of the frame. It can prevent.

As it is widely used according to the physical properties of the liquid metal 20, liquid metal has high bioactivity and low elastic modulus, low resistance to physiological rejection of body fluids, and has bio-friendly properties. The present invention is to produce a spectacle frame that has excellent lubricity and high strength to weight, excellent corrosion resistance, low elastic modulus and the like.

As described above, the spectacle frame used in various fields is composed of a liquid metal 20 alloy composed mainly of liquid metal, and in order to improve surface properties based on the entire composition of the liquid metal 20, preferably, zirconium ( 6) Niobium (7) (Nb / niobium) to improve workability mainly using (Zr / zirconium), Tantalum (8) (Ta / tantalum) and Indium (9) (In / indium) to improve corrosion resistance, etc. It may be added to a certain amount of the liquid metal eyeglass frame and a method for manufacturing the liquid metal eyeglass frame, but only the scissors, sunglasses, goggles, etc. are shown in the drawings.

Industrial spectacle frame, sports spectacle frame, cosmetic spectacle frame, medical spectacle frame, military spectacle frame and the like can be preferably applied.

In addition, the spectacle frame 40 is a liquid folding the eyeglass body 10 constituting the glasses 80 and the nose support 100 and the earrings 120 and the lens connecting portion 140 to support the glasses are all liquid. It is also preferable to use synthetic resin, silicon, rubber, etc. for the nose support 100 and the earring 120 material of the spectacle frame for integrally molded with metal or workability and manufacturing cost, and the nose support 100 and the earring 120 material. Although not shown in the drawings in order to prevent traction and slippage of the projections, it is also preferable that protrusions or slip-resistant members or ordinary contact members are formed.
