Description

The evaporation film and method manufacture vacuum evaporation film of seeing through one side}

The present invention forms a film in a multilayer structure in which the aluminum foil polyester film and the unit film bonded to the polyester film with a light-colored adhesive are formed to block ultraviolet rays and infrared rays such as windows, sun hats, blinds, verticals, billboards, and roofing materials. It relates to a one-way transparent film manufacturing method that can be made.

In modern times, as the industrial society develops and the standard of living of people improves, new products that are commonly used also tend to develop functional products. That is, a product having a new function that can simultaneously exhibit the effects of shading, see-through, design, etc. on the sun hat, blinds, verticals, billboards, roofing materials, etc. worn in summer began to develop. However, most of them have a structure in which a plastic film is sandwiched between two pieces of glass and bonded to each other, or a film is bonded to one side of single-wall glass.

For example, in the case of a film attached to a vehicle window or a film attached to an office window, the brightness of the film is generated by the transmittance of sunlight. Therefore, in order to prevent the vehicle from seeing the interior from outside, the sun transmittance of 70% or more is used, so that the driver also has a problem in view of the outside from outside, there is an inconvenience in rainy weather or at night driving.

The present invention has been invented to solve such a problem, a transparent resin coating layer, PET (deposited polyester) film layer, colorless adhesive layer, light-colored coating layer, metal metallizing to prevent scratching the film from the bottom to the top Forming a film by laminating it to be laminated with an aluminum thin layer, PET film layer, transparent adhesive layer, PET film layer, and transparent resin coating layer to reduce sunlight transmittance such as ultraviolet rays and infrared rays, so that it can be viewed only in one direction and can be worn in summer It is designed to simultaneously show the effects of shading, see-through, and design on hats, blinds, verticals, billboards, and roofing materials.

In the process of forming a scratch-resistant transparent resin coating (2 ') on the PET film (1b) to produce a one-way perspective deposition film.

The film produced in the present invention is a transparent resin coating layer / PET film layer / colorless adhesive layer / pale color coating layer / metal metallized aluminum foil deposition layer / PET film layer / transparent adhesive layer / PET film layer / transparent resin coating layer sequentially laminated will be. Such layers can be laminated to a film layer using known thermocompression and deposition methods.

In addition, the thickness of the PET film (1) (1a) (1b) and the thickness of the transparent adhesive layer (3) (3 ') and the pale color coating layer (4) can be selectively adjusted according to the use of the film.

As described above, the basic principle of the film deposition method carried out in the present invention will be described first.

The vacuum deposition method was first performed by Faraday in 1857. It is the most widely used method of thin film manufacturing. A method of forming a thin film by heating and evaporating a metal, a metal compound or an alloy in a vacuum to attach the evaporated metal or the evaporated metal compound to a surface of a target substance is called a vacuum deposition method.

The evaporation process is different from the sputtering method in that it is a heat exchange process. The manufactured thin film materials include metals, alloys and nonmetal oxides, and the functions and properties of these thin films are very diverse, and the range of use is rapidly spreading in various directions according to the trend of miniaturization, light weight, and super integration of devices.

Looking at the principle of vacuum deposition, the resistance heating vacuum deposition method requires a thermal source such as filament, basket, boat of high melting point, and a particularly popular thermal source is W, Mo, Ta, etc. Shape it as an evaporation source. It is a method of evaporating a material by placing a deposition material and heating a current through an evaporation source.

This is advantageous for the deposition of materials with low melting point, and the deposition rate is controlled by the amount of current supplied to the filament, which is wound on the filament or placed on a basket or boat and flowing current through both electrodes to maximize the heat resistance of the deposition material. It becomes vapor deposition. In selecting in consideration of the vapor pressure of the evaporation source material, it should be noted that the material of the evaporation source and the thin film material react or diffuse to any combination at high temperature to form a compound or an alloy. Because the alloy is melting point and evaporation source is easy to break.

Therefore, the material of the evaporation source should be selected as a combination that cannot be alloyed, and when it is difficult, the temperature of the evaporation source should be lowered or the amount of evaporation source material should be much larger than the amount of thin film material to suppress the consumption of the evaporation source at all. In the vacuum deposition method using the electrical resistance heat, it is desirable to increase thermal contact with the area of the deposition source so that the amount of current supplied can be sufficiently transferred to the deposition material. This method can use deposition sources of various sizes and shapes. There is an advantage.

At this time, the degree of vacuum required for vacuum deposition is 10-7 to 10-8 torr, which is high vacuum. If the vacuum is worse than this, the collision of the evaporation metals until they reach the surface of the deposit increases the particle size or oxygen in the remaining air. You can't get a good thin film by colliding with molecules and getting oxidized. To obtain this vacuum, only a rotary pump can obtain about 10-4torr, so the oil diffusion pump must be used again. This pump is used in series with the rotary pump.

Based on the deposition method made in this way, a transparent resin coating layer 3 is applied to one side of a PET film 1 having a thickness of 50 to 250 μm, which is a heat-resistant to-be-printed film, in a predetermined chamber and dried.

The drying is a natural drying, but in the case of UV-transparent ink printing, the drying in the drying chamber in the UV drying chamber in principle.

After the transparent resin coating layer is formed on one side of the PET film 1 as described above, the transparent adhesive layer 3 is applied on the other side with a thickness of 0.01 to 0.03 μm, and the light-colored coating layer 4 is formed on the upper surface, and then naturally dried. .

In this case, the transparent adhesive layer 3 and the pale color coating layer 4 may be mixed together and applied, and after forming the transparent adhesive layer, the pale color coating may be performed thereon.

The pale color coating may express a slight color by mixing a desired pigment as needed.

After forming the pale color coating layer 4, a thin metal metallized aluminum layer 5 of about 0.01 to 0.03 mm is applied by a vacuum deposition method.

After the metal metallized aluminum thin layer 5 is formed by the vacuum deposition method, a PET film layer 1a, which is a deposited polyester of about 10 to 50 mm, is formed on the upper surface thereof.

A transparent adhesive layer 3 'of about 0.01 to 0.03 mm is applied on the PET film layer 1a, and a PET film 1b of about 50 to 250 mu m is formed again on the upper surface.

At this time, the thickness of the transparent adhesive layer (3) (3 ') and the PET film (1) (1a) (1b) can be arbitrarily adjusted during manufacture according to the thickness of the film.

In the process of forming a scratch-resistant transparent resin coating (2) (2 ') on the PET film (1) (1b) to produce a one-way perspective deposition film.

The present invention may be sequentially laminated molding as described above, but it is possible to form a multi-directional perspective film of a multilayer structure formed by laminating a plurality of unit PET films and PET films, respectively.

Looking at the test results for the physical properties of the deposited film of the present invention prepared as described above are shown in Table 1 below.

As can be seen from the above table, when the film thickness is 420㎛, the visible light transmittance value is 11 and the shadow coefficient is 0.29. This indicates that the sunlight transmittance is low and the user can see the high transparency. It can be.

The present invention thus formed by forming a transparent resin coating layer on both sides of the film to prevent scratches due to contact of foreign substances and at the same time to form an aluminum foil on one side of the sunscreen or window shield for ultraviolet or infrared rays used in summer It is intended to be used as blinds, verticals, advertising signs, and roofing materials.

As described above, the aluminum foil deposition film of the present invention is capable of seeing the inside from the outside, but cannot be seen from the outside, and the window glass film of the vehicle, the sun shading film of the awning, the window blind, the vertical, and the advertisement. It can be used as a film for sun protection and ultraviolet rays, infrared rays such as signboards, roofing tinting film, etc. In particular, it is provided as a signboard for advertisement and silk printing film for advertisement to have the effect of freely expressing colors and patterns.
