In general, the wallpaper is made of vinyl or paper, and gravure printing, embossing, or double-folding paper is twisted like a thread to produce a wallpaper by adopting a method of knitting and folding. The wallpaper thus produced was divided into a tuned vinyl wallpaper or a vinyl chloride wallpaper. This wallpaper has advantages such as durability, pollution resistance, and various design expression effects.

On the other hand, most of the building is made of concrete or brick. Due to the nature of the material, there are minute pores, and cold, hot and cold air coming from the outside flow into the room. The wallpaper should play a role of blocking micropores, but it is not fulfilling its role. Various methods have been used, such as styrofoam to be used as an insulating material to block the inflow of air and adhered during construction, but its performance does not reach the needs of consumers.

Moisture from concrete or brick is also a problem, and if it cannot be solved, mold and odor occur due to moisture problems after wallpaper construction.

In addition, wallpaper complements the shortcomings of natural phenomena such as the above, and serves to block direct contact with concrete or brick by residents. However, there is no function to protect residents' body by blocking only simple contact, and especially physically weak vulnerable people are injured by colliding with the corners of bricks.

Therefore, research is constantly being conducted to improve the above problems. For example, in the published patent No. 10-2013-0112097, an insulating film wallpaper is posted, and the technical idea is that the air cap filled with air is formed so as to be arranged in a plane, and the heat insulation is suppressed by the air cap.

Advantages and features of the present invention, and methods for achieving them will be clarified with reference to embodiments described below in detail together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various different forms, and only the present embodiments allow the disclosure of the present invention to be complete, and common knowledge in the technical field to which the present invention pertains. It is provided to fully inform the person having the scope of the invention, and the invention is only defined by the scope of the claims. And throughout the specification, the same reference numerals refer to the same components.

First, with reference to the accompanying drawings of Figure 1 will be described collectively for the multi-function air cap sheet configuration and the effect, effect.

As shown in Fig. 1, the multifunctional air cap sheet according to the present invention exhibits primarily an effective resistance while absorbing an applied shock and elastically deforms an outer layer 100; A film layer 200 which has a set width and is disposed on one surface of the outer layer to exhibit a bending stress and to preserve the cross-sectional shape of the outer layer; A resin layer 300 that is viscously flowed while having adhesive strength and is distributed in a boundary region between the outer layer and the film layer; An air cap layer 400 having a plurality of semi-circular air caps 410 having a limited protruding distance, repeatedly forming convex portions and gaps on the entire surface, and exhibiting secondary effective resistance; A finishing layer 500 on which both sides are made of an adhesive surface and which one side is adhered to the air cap layer 400 to configure the inside of the air cap 410 in a low pressure state; A release layer 600 which is attached to protect the viscosity of one side of the finishing layer and is selectively peelable; It is composed of and as the resin layer 300 is viscous flow, the outer layer 100 and the film layer 200 are integrated.

The outer layer 100 is formed of polyethylene crosslinked by heat treatment at a set temperature or formed of a shape memory polyurethane having a network structure.

To connect the rubber chains dispersed in the polymer of polyethylene, a predetermined crosslinking agent is added, followed by heat treatment at a set temperature to denature and processing by adding a foaming agent to form a polyethylene foam with improved cushioning ability and reduced density. This is composed of the outer layer 100 to primarily absorb the shock applied by the user.

Polyurethane is a segmented block copolymer and is an ABABABAB alternating copolymer of hard and soft segments. The hard segment consists of a rigid molecular chain and has a glass transition temperature higher than room temperature, and the soft segment consists of a flexible molecular chain with a glass transition temperature lower than room temperature. Since they have a fine phase separation structure, they cause a shape memory effect. Moreover, since polyurethane is excellent in processability, it can be easily molded by ordinary processing technology, and exhibits excellent chemical properties in water gasoline and detergent solutions as well as resistance to organic solvents. In addition, the elastic modulus does not decrease even in a long period of 300 hours under sunlight, and it has an excellent effect in terms of biocompatibility. These polyurethanes have a simple linear structure, which may have durability that does not meet the purpose of shock alleviation sought by the present invention.

Therefore, a chain extender was added to the general polyurethane linear structure, but a crosslinking agent was introduced at a predetermined time interval to form a crosslinked form in which chemical crosslinking was introduced through a hard segment, that is, a polyurethane having a network structure to improve durability. It is preferable to be composed of the next outer layer (100). When the outer layer is composed of polyurethane having a network structure, the air cap layer 400 to be described later absorbs the residual pressure while actively accommodating the pressure applied by the user, thereby actively protecting the body of the vulnerable layer.

The coating layer 130 is a layer coated with a coating solution to which a silane coupling agent material is added and exhibits hydrophilicity.

Silane coupling agent (Silane Coupling agent) material refers to a material mixed based on silicon having two different reactors, organic and inorganic, in the same molecule. If a silane coupling agent material is used for the combination of the organic material and the inorganic material, effects such as improving the wettability of the inorganic material, substantially increasing the bending strength, increasing the adhesion of the coating and the adhesive, and increasing the moisture and weather resistance can be obtained. While adding a silane coupling agent material, the material is coated with a material that reacts aminosilane with inorganic colloidal silica (Silica Sol).

The coating layer 130 may induce coating to a microporous area existing in the outer layer by spraying the coating solution on the outer layer 100, and then code it on a separate film surface and then bond it to the outer layer 100. It might be.

For example, if water droplets are in contact with a general hydrophobic surface, the water droplets and the contact surface are made of about 90°, which can directly fall without damaging the surface droplets and damage the object at the falling point.

In order to actively improve the above problem, the coating solution exhibits hydrophilicity, which is a non-high possibility, causing surface condensation, or when the user unintentionally sprays water toward the sheet, the sheet surface exhibits hydrophilicity. This creates an angle at which the water droplets and the surface come in contact with each other at 40° or less, which induces the water droplets to flow on the surface and actively prevents damage to other products caused by water droplets.

The film layer 200 has a set width and is disposed on one surface of the outer layer to exhibit a bending stress and preserve the cross-sectional shape of the outer layer. If the overall configuration is described, it is configured to protect the shape of the air cap layer 400 and actively prevent deformation of the outer layer 100. Therefore, if you can achieve the above purpose without limitation of the material, you can say anything.

The resin layer 300 is viscously flowed while having an adhesive force and is distributed in a boundary region between the outer layer and the film layer. Here, the resin refers to a thermoplastic synthetic resin, and its types include PVC resin, polyethylene resin, and polystyrene resin.

Conventionally, a heat fusion method has been used to bond the outer layer 100 and the film layer 200. The method is to heat the film layer using heat above a certain temperature to induce bonding to the outer layer. It takes a lot of time to heat all the film layers with a large surface area, which ultimately increases the working time and burns workers during heating. Was being exposed to danger.

Accordingly, the resin of the resin layer 300 is composed of a polyethylene resin (polvethvlene resin) capable of melting at about 60 to 80°C. The resin is excellent in chemical resistance, electrical insulation and moldability, has good impact strength compared to other synthetic resins, has sufficient flexibility even at low temperatures, and is particularly preferably composed of a low pressure polyethylene resin produced by a low pressure method having excellent mechanical properties. By distributing the above polyethylene resin (polvethvlene resin) in the boundary region between the outer layer and the film layer, the outer layer and the film layer are integrated, reducing the time required for work and obtaining a body protection effect for the operator.

The air cap layer 400 is integrally formed with the film layer, but the convex portion and the gap portion are repeatedly formed. The air cap layer 400 further includes an air cap 410 made of a semicircle, and the air cap 410 further comprises repeatedly forming convex portions and gap portions in close contact with each other.

The particularly protruding convex portion of the air cap 410 accommodates air in the interior space by a protruding distance. The air capacity is proportional to the projecting distance, but it is necessary to evaluate the air capacity of the entire air cap layer 400, not merely determining the amount of air accommodated by the configuration of one air cap 410. The present invention forms an air cap having a narrow protruding distance of at least 2.5 mm and is disposed in close contact with each other. There is no gap between the air caps as a whole. As a result, the number of air caps on the surface of the air cap layer 400 is 4.5 mm to 5 mm, which is higher than the air cap layers formed at equal intervals. Therefore, the present invention can obtain an improved cushioning effect by receiving a larger amount of air than the prior art. When configured as above, the appearance is beautiful, the raw material is reduced, and the effects of heat insulation, sound insulation, and moisture resistance increase.

The finishing layer 500 is made of an adhesive surface on both sides, but one side is bonded to the air cap layer 400 to configure the inside of the air cap 410 to a low pressure state.

One side is applied with an adhesive on the corresponding surface in order to adhere to the air cap layer, and the adhesive can be any of them if it can achieve the above object. As a result, when the finishing layer 500 is joined to the air cap layer 400, the inner space of the air cap 410 is formed in a low pressure state to prevent the loss of the received air, and a buffering action is realized through the air.

The release layer 600 is attached to protect the viscosity of either side of the finishing layer, and is configured to be selectively peelable.

That is, since the finishing layer 500 should be substantially attached to the exterior wall or window, the release layer 600 is preserved until the adhesive strength of the surface to which it is attached is used. The release layer 600 may be any one as long as it satisfies the purpose of protecting the adhesive surface such as base paper, PE, and silicon.

Hereinafter, a description overlapping with the above-described configuration or effect will be avoided, and the configuration of the preferred embodiment of the air cap sheet and the resulting action and effect will be collectively described with reference to the accompanying drawings.

As shown in FIG. 2, the outer layer 100 of the present invention comprises: a first suction means 110 made of a shape memory polyurethane having a network structure to remember the shape of an impact exerted by a user exposed to the outside; It may be composed of a second suction means 120 made of polyethylene crosslinked and foamed by heat treatment at a set temperature, but integrally formed with the first suction means.

In detail, the outer layer 100 may be divided into a first inhalation means 110 and a second inhalation means 120 to which direct impact is applied, so that the body layer of the vulnerable layer can be focused on protection.

The first and second suction means 110 and 120 of polyethylene having improved shape memory, restoration, and cushioning capacity of the above-described polyurethane are configured to improve buffering capacity. Through the first and second inhalation means 110 and 120 and the air cap layer 400, the air cap sheet itself exerts a total of three shock relieving actions to actively achieve the purpose of protecting the user's body.

In addition, a coating layer 130 exhibiting hydrophilicity may be further formed using a silane coupling agent material on the divided outer layer 100, and the action and effect through the configuration are as described above.

The air cap sheet according to the present invention having the above configuration exerts a stress while absorbing a shock applied from the outside while the external layer 100 absorbs some force, and then the air cap layer 400 buffers the residual force as children, the elderly And to secure the body of the vulnerable groups such as the disabled. In addition, as the air caps 410 having a narrow protruding distance of the air cap layer 400 are repeatedly formed in close contact with each other, there is an advantage of improving all of the problems occurring in the related art to improve the user's satisfaction.

In addition, by inducing the chain action of the first suction means 110, the second suction means 120, the air cap layer 400, so as to actively express the impact relief action. Accordingly, there is an advantage of actively protecting the body of the vulnerable, which is one of the objectives of the present invention.

Hereinafter, with reference to the accompanying drawings of FIGS. 3 to 4, the stepwise flow, action, and effect of the method for manufacturing the air cap sheet will be collectively described.

3 to 4, the outer layer forming step (S100) of forming the outer layer 100 that exhibits an effective resistance and elastically deforms while absorbing an applied shock; A film layer forming step (S200) of forming a film layer 200 that has a set width and is disposed on one surface of the outer layer to exhibit a bending stress and to preserve the cross-sectional shape of the outer layer; A resin layer forming step (S300) of forming a resin layer 300 by passing through a molding roller in a state in which the resin flowing viscously is distributed in the boundary region between the outer layer and the film layer; The air forming the air cap layer 400 by extruding in contact with the film layer 200 to form a convex portion and a gap portion on the entire surface by closely forming the semi-circular air cap 410 having a limited protruding distance. Cap layer forming step (S400); After providing a finishing layer 500 made of adhesive surfaces on both sides, an adhesive is further applied to one surface to bond with the air cap layer 400, and to the other surface, a release layer 600 capable of protecting the adhesive surface and selectively peeling off is provided. It is composed of; finishing step (S500) to form.

In addition, the outer layer forming step (S100) is a first suction means forming step (S110) of forming a first suction means (110) with a polyurethane having a chemical cross-linking structure by adding a chain extender and a crosslinking agent to the set prepolymer; A second suction means forming step (S120) of integrating with the first suction means but forming the second suction means 120 with cross-linked foamed polyethylene; A coating layer forming step of forming a coating layer 130 by applying a hydrophilic coating solution to the first suction means (S130); It may further include an impact effective resistance and elastic force applied to the outer layer 100.

More specifically, the outer layer forming step (S100) may form the outer layer 100 with a cross-linked polyethylene commonly used, or the outer layer 100 with a shape-memory polyurethane having a network structure.

The polyurethane is prepared by prepolymer based on 4,4'-methylene bis, poly(tetramethylene glycol), poly(ethylene glycol), and then dissolved in N,N-dimethylformamide (DMF) to extend and crosslink the chain. Using 1,4-butanediol and glycerol, the titration of the OH value of the polyurethane is artificially introducing another urethane chain between the crosslinking points by adding MDI and PEG with the OH of the crosslinking agent as the crosslinking point. The polymerized polyurethane is dissolved in dimethylformamide (DMF) and heat-treated at 60°C for 50 hours to form a layer of a predetermined thickness.

The results of comparing the shape recovery rate over time after fixing the shape by applying pressure to each of the polyurethane having the network structure polymerized by the chemical crosslinking and the polyurethane having a simple linear structure are as follows.

Time(min) Network structure (%) Linear structure (%) 2 86 80 6 92 82 12 96 85

As such, it can be seen that the polyurethane having chemical crosslinking has a slightly higher shape recovery rate, which is attributable to the fact that it has a more uniform network structure than the linear structure. Table 1 above suggests that the shape can be recovered faster than the above results if it has a uniform structure through the selection of a crosslinking agent, titration of OH value, and the like.

Therefore, if the outer layer 100 is to be formed of polyurethane, it is desirable to form a network structure with chemical crosslinking to actively absorb the shock applied by the user and then to remove the possibility of recovery from elastic deformation. something to do.

In another embodiment, the configuration of the first suction means 110 is as described above even when the outer layer 100 is divided into the first suction means 110 and the second suction means 120.

The coating layer forming step (S130) forms a coating layer 130 exhibiting hydrophilicity by adding a silane coupling agent material to the outer layer 100 formed through the outer layer forming step (S100).

In order to form the coating layer 130, the coating solution is 3-(triethoxysilane)propylamine (3-aminopropyltriethoxysilane) and 3-aminopropine trimethoxysilane (3), respectively, which are silane coupling agents. A hydrophilic coating solution is prepared by using -aminopropyltrimethoxysilane and reacting aminosilane with colloidal silica (Silica Sol).

On the other hand, epoxy silane (epoxysilane), which is commonly used in the manufacture of a hydrophilic coating solution, may be used, but a separate cross-linking agent is required in manufacturing, and there is a problem that the usability of the coating solution is poor.

Therefore, it would be desirable to improve the usability by utilizing aminosilane among reactants. The mixed coating solution may be coated on a separate film paper and then bonded to the outer layer 100 or directly coated on the outer layer 100.

The coating layer 130 is formed on a cross-section exposed to the outside, and thus must have water resistance. In particular, a separate film paper having a coating layer 130 of different thickness in a 40° C. thermostat to examine the effect of the coating thickness on the water resistance. The results are as follows.

1,020nm 102nm 10 days elapsed 1,020nm 102nm 30 days elapsed 1,020nm 82nm

As shown above, the coating film having a coating thickness of 1,020nm had no loss of the coating layer even after 30 days, and the coating film having a coating thickness of 102nm was found to have lost the coating layer to 82nm after 30 days. have.

As a result, the thicker the thickness, the better the hydrophilicity and the durability of the coating layer does not decrease with time, so it will be desirable to form a coating layer 130 having a certain thickness or more according to the situation.

The film layer forming step (S200) is configured to have a cross section corresponding to the outer layer, but forms the film layer 200 disposed on the rear of the outer layer, and the corresponding film layer can be composed of commonly used film paper and is later extruded and bonded. As it protects the surface of the air cap layer, the outer layer and the air cap layer are integrated. It can be integrated through a T die.

In the resin layer forming step (S300), the resin layer 300 is formed by passing through the molding roller in a state in which the resin flowing viscously is distributed in the boundary region between the outer layer and the film layer.

The resin includes a low pressure polyethylene resin prepared by a low pressure method that melts at about 60 to 80°C.

Distributing the viscous resin in this way is intended to improve the problems in the conventional heat fusion method, and after coating the liquid resin in the molten state, the outer layer 100 and the film layer 200 are applied through a T die. To be integrated. By adopting such a process, it is possible to improve the problem of working time required for heating during heat fusion and eliminate the risk of being exposed to workers' burns during the heating process.

In the air cap layer forming step (S400), the semi-circular air cap 410 having a limited protruding distance is closely formed to form convex portions and gaps on the entire surface, but is extruded in surface contact with the film layer 200. The air cap layer 400 is formed.

In the air cap layer 400, an air cap 410 having a semicircular shape is formed around its surface area, and through the air cap, the air cap layer is repeatedly formed with a convex portion and a gap portion. The particularly protruding convex portion of the air cap 410 accommodates air in the interior space by a protruding distance. The air capacity is proportional to the projecting distance, but it is necessary to evaluate the air capacity of the entire air cap layer 400, not merely determining the amount of air accommodated by the configuration of one air cap 410. The present invention forms an air cap having a narrow protruding distance of at least 2.5 mm and is disposed in close contact with each other. There is no gap between the air caps as a whole. As a result, the number of air caps on the surface of the air cap layer 400 is 4.5 mm to 5 mm, which is higher than the air cap layers formed at equal intervals. Therefore, the present invention can obtain an improved cushioning effect by receiving a larger amount of air than the prior art. When configured as above, the appearance is beautiful, the raw material is reduced, and the effects of heat insulation, sound insulation, and moisture resistance increase.

The air cap 410 as described above is formed on the air cap layer 400 and then laminated with the film layer 200 through a T die to be integrated with the outer layer 100 and the film layer 200 as a whole. .

In the finishing step (S500), both sides are provided with a finishing layer 500 made of an adhesive surface, and then an adhesive is further applied to one surface to be bonded to the air cap layer 400, and the adhesive surface is protected and selective peeling is applied to the other surface. A possible release layer 600 is formed.

Eventually, the present invention can be used as a wallpaper for concrete and bricks, or alternatively, it can be used as an insulating sheet for windows. Before use, the release layer 600 is attached to protect the adhesive surface, and the release/release mechanism is exerted by exfoliating the release layer 600 according to the user's selection during use.

The present invention described above has been described with reference to one embodiment shown in the drawings, but this is only an example, and various modifications and equivalent other embodiments are possible from those skilled in the art. Should be clarified. Therefore, the true technical protection scope of the present invention should be interpreted by the appended claims, and all technical spirits within the equivalent scope should be interpreted as being included in the scope of the present invention.
