Description

This project is related to various protective sheets that are attached to the surface to protect the main body. When a protective sheet is applied to the surface to be protected, dust and air bubbles are prevented to a minimum, and positioning is required when applying the protective sheet. The present invention relates to a protective sheet having a function that can be easily performed.

In general, for surface protection sheets to protect the main body from scratches, sheets and windows that protect LCD screens of personal computers, game machines, TVs, mobile phones, smartphones, car navigation systems, vending machines, medical equipment, ticket vending machines, etc. In order to protect the main body from scratches and dirt in various fields, such as glass, mirrors, refrigerators, pianos and other sheets that protect the surface from scratches, they were developed with names such as protective sheets, protective films or protective seals. There are protectors that are widely used and are indispensable for work and daily life, but there were almost no special measures for their attachment.

Since the range of use is wide, the liquid crystal protective sheet will be mainly described as a reference object for explanation as a representative example, but this explanation applies to all products having the surface protecting function as described above.

Recently, the spread of mobile phones called smartphones and the spread of tablet computers are remarkable, the frequency of using LCD screens is very high, and the protective sheet as a function to protect the LCD screen itself from scratches and dirt is Although it has come to be used many times, the effect on the liquid crystal screen itself is limited, and there are not enough considerations on how to stick it, and the general consumer's sticking technique is good and bad. During this period, it was difficult to prevent air from remaining as much dust and bubbles.

The size of the LCD screen is increased, and the protective sheet is required to have a complicated shape. A special shape with a small hole for a microphone or speaker is applied to a part of the LCD screen, so that the LCD screen can be attached to the original position. It has become very difficult to paste accurately.

Although the present invention is a protective sheet devised to eliminate the sticking failure of the protective sheet due to the difference in the human person's method of sticking, even if you look at the LCD protective sheet as a representative, Various proposals have been made so far, but other protectors have hardly been devised. The present invention has a characteristic that can be applied to all protective sheets for protecting an object that requires such protection.

In the device of the above-mentioned patent document, the liquid crystal protective sheet that adheres to the liquid crystal screen as the adherend is characterized by a separate film that is a protective layer of the adhesive layer and the adhesive layer until it is actually attached, and the liquid crystal protective sheet is liquid crystal. This makes it possible to prevent air bubbles and dust from being mixed and to be easily pasted on the screen. However, it is necessary to replace the separate film that is peeled off when it is applied and replace it with a kind of special function. Has not been solved.

The method of realizing dust mixing suppression and ease of application when attaching a liquid crystal protective sheet by putting a crease or perforation in or separating the separated film is to be used at the time of manufacturing the separate film. It is time consuming and expensive during processing, requiring complicated work steps to achieve the desired effect, and it can be used as an adhesion layer by cutting, stacking, and folding folds of separate films. This affects the silicone layer, the acrylic adhesive layer, or the urethane adhesion layer itself, and cannot be denied the possibility of the residue or modification of the adhesion material.

When manufacturing a liquid crystal protective sheet with a separate film in accordance with the structure of the device itself that has a liquid crystal screen, the device that is the adherend is limited, and in products manufactured for a limited model, other models are used. Since there is a problem that it cannot be applied at all, versatility is not satisfied, and there is an aspect that cannot be said to be a method that can contribute widely to society.

In the present invention, there are problems that need to be replaced with a separate film having special functions as described above, problems that affect various adhesive layers, problems of versatility that depend on the model, and the effort and cost required to achieve this. In addition to solving all of the above problems, it is an object of the present invention to provide a method for realizing target dust mixing suppression, bubble mixing suppression, and prevention of a problem of deviation from a position where it should originally be applied.

When sticking a protective sheet to an adherend, the method of peeling off all the separate films that protect the adhesive layer and the adhesive layer, and a separate film that remains after the part is peeled off and positioned with the adherend There is a method of sticking while peeling.

The former peels off the separate film all at once and exposes the adhesive layer and adhesive layer. Therefore, dust and air bubbles are likely to enter between the protective sheet and the adherend when affixing, and the exposed adhesive layer and adhesive layer are exposed. Touching the layer directly with your hand is likely to occur, and the adhesive layer or adhesive layer may be soiled and damaged. Since the adhesive layer may come into contact with the adherend, it becomes very difficult.

The latter is the method used in this project.Since part of the separate film is peeled off in this way, it is possible to secure a portion where the adhesion layer and adhesive layer are exposed and a portion that is not exposed. By bringing the uncovered part into contact with the adherend, it can be moved freely on the adherend, allowing easy positioning and minimizing adverse effects such as dust and scratches on the adhesive layer and adhesive layer. It can be suppressed.

However, with the latter method alone, the elasticity of the separate film will return to its original state, and some of the separate film that has been peeled off for easy attachment will return to its original state. Such a situation tends to occur, and the separation work of the separate film must be repeated.

Therefore, the present invention applies a double-sided tape to the outer side of the separate film that protects the adhesion layer and the adhesive layer where the protective sheet directly adheres to the adherend, so that the protective sheet is attached once to the adherend. This has the effect of fixing the peeled-off separate film, which makes it easier to stick the protective sheet to the correct position on the adherend, and sticking while peeling off the separate film. Anyone can easily and inexpensively demonstrate the effect of preventing this.

The position where the double-sided tape is applied may be anywhere outside the separate film that protects the adhesive layer and adhesive layer of the protective sheet. However, in order to prevent dust from entering between the adherend and the protective sheet, actual work is required. The size of the protective sheet is easy to attach to the adherend when the user turns the adhesive layer or adhesive layer separate film and turns it back. In the present invention, only a part of the adhesive layer or adhesive layer is used as shown in FIG. The size to be exposed can be determined arbitrarily by the worker applying the protective sheet, so it is possible to determine the size that is easy for the operator to work, and to make the worker feel stress due to restrictions on how to apply Has been eliminated.

The protective sheet with the present invention can minimize the size that the adhesion layer and adhesive layer are exposed to the operator's request, minimizing the mixing of dust during application. Has the effect of

Since the separate film is folded and fixed with the double-sided adhesive layer, the exposed part of the adhesive layer and the adhesive layer and the two parts that are not exposed can exist at the same time without being held by hand. In this state, the part where the adhesion layer or the adhesive layer is not exposed is brought into contact with the adherend, and the protective sheet can be easily aligned with the correct position in a state where the position can be moved, as shown in FIG. By pressing the adhesive layer or the adhesive layer from the upper part of the exposed portion, the adhesive layer or the adhesive layer is brought into contact with the correct target position as shown in FIG. 4, and the protective sheet is fixed at a certain position on the adherend. It becomes possible.

After deciding the affixing position, a part of the bare adhesion layer or adhesive layer is affixed to the adherend first, the position is fixed, and then the affixed to the adherend while gradually peeling off the separate film. Since the affixing method is naturally executed, this is a flow in which the protective sheet is affixed in order from one side, so that mixing of bubbles can be minimized.

The protective sheet applied by this method not only prevents dust and bubbles from being mixed and determines the correct application position, but also has an effect of preventing damage to the adherend and preventing dirt.

The present invention can be applied to any type of protective sheet, and can be easily applied to protective sheets not provided with the present invention.

Since there is no need to replace the separate film in this device, there is no possibility of dust mixing between the adhesive layer or the adhesive layer and the separate film, and it is necessary to make a crease or perforation. Since there is no contact, the protective sheet can be held in the best condition without being folded into the adhesion layer or the adhesive layer or leaving a perforation mark, and can be used in the best condition in actual use.

By using a protective sheet equipped with this device, it is possible to prevent dust from entering, suppress air bubbles from entering, determine the exact location, prevent scratches on the adherend, and prevent dirt from adhering to the adherend. Realization is cheaper than previous inventions and devices, and can be easily applied to all protective sheets without this device without limiting the protective sheet. It is possible to realize a protective sheet that is highly effective and highly effective in contributing to society.

By structuring the double-sided adhesive layer outside the protective layer of the adhesion layer or the adhesive layer, a surface protective laminated sheet that can obtain the effects of the present invention can be realized.

The protective layer of the double-sided adhesive layer of 5 in FIG. 1 is peeled off, the adhesive layer of 3 and the protective layer of the adhesive layer are partially peeled and bent, and the exposed double-sided adhesive layer of 4 is attached to 3 By sticking to the protective layer of the adhesive layer or adhesive layer, the surface protection laminated sheet with double-sided adhesive layer is ready for use, and by sticking it to the adherend, it is easy to express the surface protection expressed in this project The effect can be implemented.

Since the present invention is a device that can be obtained only by structuring a double-sided adhesive layer in addition to the generally known surface protective sheet base material, adhesion layer, adhesive layer and its protective layer, it does not take time and effort. Since it can be easily manufactured at a low cost, it can be easily applied to existing products as well as structurally manufactured at the time of new manufacturing, so it is possible to easily make products that have the effect of contributing to society.
