As shown in FIG. 1, the double-sided tape 21 is formed in a shape having a hollow in the center for light transmission, and is attached to an edge portion of either side of the red film 11. Therefore, the first coupling portion combined with the monochromatic light module 1 composed of the red film 11 becomes one surface 211 of the double-sided tape 21, which becomes the upper surface based on FIG. 1, and is a rear view. ] And the side view of FIG. 1 [C], which can be more clearly confirmed.

In addition, the other side 212 of the double-sided tape 21 forms a second coupling portion that is coupled with the smartphone S, and the other side 212 of the double-sided tape 21 becomes a lower surface based on FIG. 1. The other surface 212 of (21) is directly attached to the smart phone (S) so that the device can be coupled to the smart phone (S) in the form as shown in FIG.

The device according to the first embodiment is easily attached so that the red film 11 can cover the camera C and flash F of the smartphone S, and is easily removed even in the removal process after detection of the voyeur camera, so that it is easy to use. It offers the advantage of being very easy. However, since it is mounted on the smartphone S by the adhesive force of the double-sided tape 21, there is a disadvantage that it must be used for a single time.

Next, the second embodiment complements the disadvantages of the disposable use of the first embodiment, and the coupling means 2 is installed in the smartphone case SC to install the device through the smartphone case SC. It is intended to present a method of coupling to the phone (S).

According to the second embodiment, the apparatus further includes a frame 12 including a mounting portion 121 in which the monochromatic light module 1 is provided on the outer side of the red film 11 and the red film 11 is mounted in the center. And, the engaging means (2) is installed in the smart phone case (SC) and is composed of a slider 22 with a through-hole 220 in the center, whereby the first engaging portion is a slider along the perimeter of the through-hole 220 It is formed on the inner surface of (22) and is composed of a receiving groove (221) for receiving the end of the frame 12, the second coupling portion is characterized in that it can be composed of a smart phone case (222, SC). In order to highlight the smart phone case 222 performing the function of the second coupling part from the smart phone case SC in charge of a general protection function, reference numeral 222 is written in parallel, hereinafter referred to as SC only.

3 to 4, the frame 12 is provided on the outer side of the red film 11, and the red film 11 is mounted on the mounting portion 121 provided at the center of the frame 12. The frame 12 serves to impart rigidity so that the red film 11 can be moved within the slider 22.

Also, as shown in FIGS. 3 to 4, the slider 22 has a through-hole 220 in the center, and the first coupling portion is formed on the inner surface of the slider 22 along the periphery of the through-hole 220. By being composed of a receiving groove 221 to accommodate the end of the frame 12, the red film 11 is in the form of blocking the through-hole 220, the monochromatic light module 1 is coupled to the slider 22.

Here, an attachment means such as an adhesive or an adhesive tape, a fixing means such as a bolt, a rivet, a stapler, or the like may be used for coupling between the slider 22 and the smartphone case SC, and is not limited to any one type. As described above, since the monochromatic light module 1 composed of the red film 11 and the frame 12 is coupled to the slider 22 installed in the smartphone case SC, the smartphone case SC is a smartphone S When coupled to, the monochromatic light module 1 is naturally coupled to the smartphone S.

Since the device according to the second embodiment is provided on the smart phone S through the smart phone case SC, it can be continuously used. In particular, the monochromatic light module 1 is moved inside the slider 22 to voyeur camera. During detection, the red film (11) covers the flash (F) and the camera (C), and in the non-detection normal situation, the flash (F) and the camera (C) are separated from the flash (F) and the camera (C). Enable use.

This effect can be confirmed through FIG. 5, as shown in FIG. 5 [A], when the voyeur camera is detected, the monochromatic light module 1 coupled to the slider 22 is disposed in a position covering the opening hole H do. This opening hole (H) is a hole where the flash (F) and the camera (C) are exposed, and when the monochromatic light module (1) is placed in the opening hole (H) position, the red film (11) flash (F) and the camera ( C) is covered.

In addition, as shown in FIG. [B], in the normal situation in which the voyeur camera is not detected, the monochromatic light module 1 is moved in a direction away from the open hole H to open the open hole H, and at this time, the flash ( F) is an original function of irradiating white light, and the camera C can perform an original function of image shooting.

In addition, as shown in FIG. 5 [C], it is also possible that the slider 22 and the smartphone S are integrally formed by bonding, and in this case, the opening hole H of the smartphone case SC Can be omitted.

In the above, the monochromatic light module 1 is moved within the slider 22 for switching between detection and non-detection states, and the movement of the monochromatic light module 1 includes an end of the frame 12 along the receiving groove 221. It is the above room that can be realized by being guided and moved. In order to move the monochromatic light module 1, one more condition must be added to this, which means that the length of the through-hole 220 and the receiving groove 221 should be larger than the length of the frame 12.

That is, as shown in Figure 6, the through-hole 220 is that the length of the horizontal or vertical should be formed at least two times larger than the length of the horizontal or vertical red film (11).

FIG. 6 [A] shows an embodiment in which the transverse length h220 of the through-hole 220 is formed at least twice as large as the transverse length h11 of the red film 11, which is the transverse direction of the monochromatic light module 1 Corresponds to the conditions applied when moving. And in Figure 6 [B] is shown an embodiment in which the vertical length (v220) of the through-hole 220 is formed at least twice as large as the vertical length (v11) of the red film (11), which is the monochromatic light module (1) Corresponds to the conditions applied at the time of vertical movement, in particular, the implementation as shown in FIG. 6 [B], the flash (F) and the camera (C) of the smartphone (S) is centered on the basis of the horizontal direction of the smartphone (S) When provided, the monochromatic light module 1 can be effectively applied when it needs to be moved in the vertical direction.

Next, according to the third embodiment, as shown in FIG. 7, the device is characterized in that the coupling means 2 may be composed of an adhesive 23 provided on the lower surface of the red film 11. . Accordingly, both the first coupling portion and the second coupling portion may be configured by the adhesive 23.

The adhesive 23 is adhered to the red film 11 and at the same time adhered to the smart phone (S), and combines the red film 11 and the smart phone (S).

In particular, the adhesive 23 should be made of a transparent (colorless) material so as not to act as an obstacle to the detection of the voyeur camera, and the degree to which the removal of the red film 11 (monochromatic light module) can be easily performed after the voyeur camera detection. It should be composed of a material having an adhesive force, and the type is not particularly limited in the line satisfying these conditions.

It is preferable that the adhesive 23 is protected by a release paper (p), and in FIG. 7 [A], the configuration of the release paper (p) provided on the lower surface of the red film 11 can be confirmed, and the release paper (p) is The red film 11 serves to protect the adhesive 23 until it is adhered to the smartphone S, and is removed immediately before being attached to the smartphone S of the red film 11.

On the other hand, the red film 11 needs to be protected from external factors, and the present invention is a means for protecting the red film 11, where the monochromatic light module 1 is applied to the red film 11 and applied to the curing agent. Characterized in that it may further include a protective film provided by.

Such a protective film should be easily provided, and must have excellent adhesion, and further, should have improved antiseptic properties, fire resistance, and rust resistance. In addition, there is a need to provide improved manufacturability due to rapid curing, and improved waterproofness through water repellent treatment. .

The protective agent composition for the protective film of the present invention providing the above effects is 100 parts by weight of phenoxyethyl acrylate, 150 to 250 parts by weight of polyester acrylate, 30 to 40 parts by weight of 2,4,6-trimethylbenzoyldiphenylphosphine oxide Part, 50 to 100 parts by weight of polyvinyl acetate, 1 to 5 parts by weight of 2-methyl-4-isothiazolin-3-one, 25 to 35 parts by weight of silica airgel, 10 to 3-glycidoxypropylmethyldimethoxysilane 25 parts by weight, sodium silicate 30 to 50 parts by weight, hydroxyethyl acrylate 10 to 70 parts by weight, ethyl siliconate 30 to 60 parts by weight, ethylenediaminetetraacetate 1 to 5 parts by weight, tetraethoxysilane 0.5 to 2.5 parts by weight Includes wealth.

For each component, (Phenoxyethylacrylate) phenoxyethyl acrylate is first used as an acrylate-based monomer, and has been confirmed to be the most suitable for the present composition among various acrylate-based monomers because it has adequate flowability and excellent heat resistance. The amount of each composition to be described later will be described based on 100 parts by weight of this phenoxyethyl acrylate.

Next, (Polyesteracrylate) polyester acrylate is used as an acrylate oligomer, and has been found to be most suitable for the present composition among various acrylate oligomers because it has proper adhesion, strength, and durability. The polyester acrylate is preferably used in an amount of 150 to 250 parts by weight, and when used outside the above numerical range, it has been confirmed that the adhesion, strength and durability of the protective film are significantly reduced. As a result of repeated experiments, the most preferred amount was found to be 200 parts by weight.

Next, (2,4,6-Trimethylbenzoyldiphenylphosphineoxide) 2,4,6-trimethylbenzoyldiphenylphosphine oxide is used as an initiator, and when used together with the above-mentioned phenoxyethyl acrylate and polyester acrylate among various initiators It was confirmed that the best physical properties can be secured. The 2,4,6-trimethylbenzoyldiphenylphosphine oxide is preferably used in an amount of 30 to 40 parts by weight, and when used in an amount of less than 30 parts by weight, formation of sufficient radicals is difficult, and when used in excess of 40 parts by weight, physical properties This is remarkably lowered, and when used outside the above composition range, a noticeable decrease in physical properties was observed, especially in curing time and flowability. As a result of repeated experiments, the most preferred amount was found to be 35 parts by weight.

Next, (Polyvinylacetate) polyvinyl acetate is used as a fixing agent that improves the fixing force of the protective agent, and the amount is preferably 50 to 100 parts by weight. For example, when used in an amount of less than 50 parts by weight, there is a problem in that the protective agent is not well adhered due to a decrease in flexibility of the coating film, and when used in excess of 100 parts by weight, there is a problem in that the dryness of the protective agent decreases. As a result of repeated experiments, it was found that the optimum amount was 70 parts by weight.

Next, (2-Methyl-4-Isothiazoline-3-one) 2-methyl-4-isothiazolin-3-one is used as a preservative, and the amount is preferably 1 to 5 parts by weight. When used outside the above composition range, there was no obvious problem, but repeated experiments showed the most remarkable effect in the above composition range.

Next, (Silica Aerogel) silica airgel is a composition that serves to enhance fire resistance and heat insulation based on the diffused pores, and is used as a refractory agent and heat insulating agent. Silica aerogel is a material having a very large specific surface area having a porosity of 80 to 99.87% and a pore size of 1 to 50 nm, and is a transparent ultra-low density material, characterized by high light transmittance and low thermal conductivity, so it has high potential as a transparent insulation material. Have The silica aerogel absorbs moisture, and thus the gel structure properties and physical properties are deteriorated, so that the surface is preferably hydrophobized, and the amount is preferably 25 to 35 parts by weight. When used outside the above composition range, there is a problem that optimum physical properties cannot be secured, and in particular, when used in excess of 35 parts by weight, a problem in economic efficiency is deteriorated. As a result of repeated experiments, it was found that the most preferable amount was 30 parts by weight.

Next, (3-Glycidoxypropylmethyldimethoxysilane) 3-glycidoxypropylmethyldimethoxysilane is used as a coupling agent to improve physical properties by increasing the interfacial adhesion of each composition, especially polymer compositions, and the amount used is 10 to 25 parts by weight. desirable. When used outside the composition ratio, the binding force between the compositions is not effectively expressed. As a result of repeated experiments, the most preferable amount was found to be 20 parts by weight.

Next, (Sodiumsilicate) sodium silicate is added as a rust inhibitor, there is an advantage of a relatively good economic efficiency among various rust inhibitor compositions. The preferred amount of sodium silicate is 30 to 50 parts by weight, for example, when it is used less than 30 parts by weight, it is difficult to guarantee the anti-corrosive ability, and when used in excess of 50 parts by weight, there is a problem that economic efficiency is deteriorated. The optimal usage amount considering both economic efficiency and rust prevention capacity is 40 parts by weight.

Next, (Hydroxyethylacrylate) hydroxyethyl acrylate is added as an adhesion enhancer, and hydroxyethyl acrylate is particularly advantageous because it has excellent curability. The preferred amount of use is 10 to 70 parts by weight, for example, when used in an amount of less than 10 parts by weight, the adhesion promoting effect is not properly expressed, and when used in excess of 70 parts by weight, there is a problem that the volatility increases and the toxicity becomes strong. As a result of repeated experiments, it was found that the most preferred amount was 40 parts by weight.

Next, (Ethylsiliconate) ethylsiliconate is added as a strength strengthening agent to increase the corrosion resistance, impact resistance, scratch resistance (tolerance of scratch / scratch) and surface hardness of the protective film, and the average particle size is 10 to 20 nm. Preferably, the preferred amount is 30 to 60 parts by weight. For example, when used in less than 30 parts by weight, sufficient strength cannot be obtained, and when used in excess of 60 parts by weight, the possibility of cracking after construction increases due to excessive stiffness. As a result of repeated experiments, it was found that the most preferred amount was 40 parts by weight.

Next, (Ehtylenediaminetetracetate) ethylenediaminetetraacetate is used as an adsorption enhancer, and enhances the adhesion by consequently enhancing the adsorption power during the initial construction of the protective film. The preferred use amount of ethylenediaminetetraacetate is 1 to 5 parts by weight, and when used outside the above composition range, the adsorption strengthening effect is not adequately expressed.

Next, (Tetraethoxysilane) tetraethoxysilane is hydrolyzed and condensed to impart waterproofness and water repellency to the protective film and is added to improve antiseptic properties, and preferably 0.5 to 2.5 parts by weight is used. The effect of improving waterproofness, water repellency, and antiseptic properties is negligible, and when used in excess of 2.5 parts by weight, there is a problem in that workability is deteriorated. As a result of repeated experiments, the most preferable amount was found to be 2 parts by weight.

The protective film of the present invention having a limitation of the above-described configuration and composition range does not require a drying temperature limitation, and since the curing is rapidly performed without flowability, the protective film is easily provided, and further excellent adhesion, as well as improved antiseptic and fire resistance , It has an anti-rust property, and in addition, has the advantage of excellent water resistance.

Therefore, the overall curing time in Examples 1 to 3 belonged to the short side, and it was confirmed that rapid curing was performed without flowability in all three examples.

[Experimental Example 2]

As a result of performing cross-cut on each of the test sheets of Examples 1 to 3, no peeling occurred at all within Examples 1 to 3 within an error range of 1% (less than 1% peeling rate).

Subsequently, as a result of performing a scratching experiment through a scratcher having irregular protrusions on the outer surface of each of the test sheets of Examples 1 to 3, in Example 1, most of the protective film was damaged, and in Examples 2 and 3, the error range was 5%. There was no breakage of the protective film in the interior (breakage rate less than 5%).

Therefore, it was confirmed that Examples 2 and 3 had superior adhesion and strength to the protective film compared to Example 1.

[Experimental Example 3]

As a result of performing an experiment of directly spraying a flame for 10 minutes through a torch on the outer surfaces of the test sheets of Examples 1 to 3, some combustion and melting occurred in Examples 1 and 2, but a slight soot occurred in Example 3 However, the protective film did not burn at all.

Therefore, it was confirmed that Example 3 was superior in fire resistance and heat insulation compared to Examples 1 and 2.

[Experimental Example 4]

After spraying water on the outer surface of each of the test sheets for Examples 1 to 6 for 6 hours, a small amount of moisture was detected in Examples 1 and 2 as a result of removing the protective film and examining the internal invasiveness of the test sheet. At, no moisture was detected.

Therefore, it was confirmed that Example 3 was superior in water resistance compared to Examples 1 and 2.
