A manufacturing method of an air cell using an elastic fiber fabric, and an air cell structure and a heat mat manufactured therefrom.

The present invention relates to a method for manufacturing an air cell using an elastic fiber fabric, and an air cell structure and a heat mat produced thereby, more specifically, to improve the surface feel and visual effect by laminating an elastic fiber fabric on a TPU film. It is about technology.

The air cushion mat is filled with air inside, and the outside is usually made of polymer resin such as vinyl, so its shape retention is good, light, and excellent in heat insulation, so it is often used as a floor covering for cushions in homes and offices or camping grounds.

However, these air cushion mats have a surface that is made of a polymer material such as vinyl, and thus, when it comes in direct contact with the skin, it is difficult to be seen as a high-quality material, such as poor feel and visually vinyl feeling.

Therefore, conventionally, air cushion mats are often used on a floor and covered with cushions or cloths. In this case, since the air cushion mats and cushions or cloths move separately, there is a problem of reduced convenience.

On the other hand, in the case of a nursing hospital or a hostess ward, even in the case of the elderly, critically ill, or the general public living in the home, it is difficult to move the body when the body is uncomfortable. There is a need to develop technology to do this.

As a related technology, the Republic of Korea Patent Registration Publication No. 10-1217014 "A wheel chair for preventing bedsore" (Patent Document 1) mainly behaves after paralysis of an anal disease patient after hemorrhoids surgery or before or after childbirth, or the lower body In order to keep the skin of the buttocks of the incompetent handicapped in a comfortable state, a space between the wheelchair and the skin of the body is provided to provide comfort, while distributing the load on a specific part of the body to prevent blood circulation disorder and a large amount of cushioning. It relates to a wheelchair for preventing bedsores that improves the ventilation function to form a ventilation hole to smoothly maintain skin breathing.

In addition, the Republic of Korea Patent Registration Publication No. 10-0925492 "Anti-bedsore having a variable temperature unit (ANTI-BEDSORE AIR MATTRESS COMPRISING HEATING UNIT)" (Patent Document 2) is provided on the cover member and the cover member inside It comprises a cell member that is individually expanded and a variable temperature unit installed under the cell member.

It is to provide a thermal massage mat for preventing bedsores, which is equipped with an anti-bedsore function by tapping the necessary areas and providing breathability.

However, the patent documents 1 to 4 are limitations that overlook the problem of pressure sores due to humidity, in addition to the problem that pressure is continuously applied to parts of the body when sitting or lying in one posture corresponding to the cause of pressure sores. There is this.

In order to solve this problem, the present applicant has applied for a technology related to a pressure ulcer prevention heat mat {HEAT MAT FOR PREVENTING BEDSORE} through a separate patent, but the conventional application relates to structural characteristics of the air cell structure and directly contacts the body. Synthetic resins such as polyurethane, polyvinyl chloride, polyethylene, polyester, silicone, and polycarbonate are used, but these materials have a limitation in that the surface feels poorly in contact and is visually bad. Accordingly, in this field, in order to solve such tactile and visual problems, a thin cloth-like fiber is covered and manufactured, but it is difficult to laminate and synthetic resins, and there has been a problem of frequent separation and washing.

FIG. 9 is a view showing a state in which the sensor module set 150 is formed in the air cushion pad set 112 among the heating mats 100 of FIG. 3.

First, referring to Figure 1, the air cushion pad assembly 112 is formed of a plurality of air cushion units (112u), each air cushion unit (112u) is an elastic fiber fabric (112u-1), TPU film (112u- 2), and may be formed of a triple structure of the air cell (112u-3).

TPU film (112u-2) is formed by wrapping the inside of the elastic fiber fabric (112u-1) corresponding to the outer shell, TPU resin, a mixture of functional additives for the generation of far infrared rays and negative ions, etc. The shape stability of the air cell 112u-3 when air is injected into the air cell 112u-3 of the air cushion unit 112u constituting 112 may be improved and a body vitality function may be provided.

The air cells 112u-3 may be formed independently or may be formed in a structure in which air injected with each other through a parallel extension tube 115 formed on the TPU film 112u-2 can communicate. The air cell 112u-3 may be arranged in a matrix form so that the gas can be smoothly communicated through the parallel extension pipe 115.

The air cell 112u-3 includes a first air cushion pad 112a, a second air cushion pad 112b, and a third air cushion pad formed by a set of air cushion units 112u as shown in FIGS. 3 and 4. 112c) In addition to preventing damage due to the upper pressure in each of them, it is possible to stably accommodate the body part of the intestine, and provide an effect of preventing bedsores on skin, etc., in close contact with the bed.

Next, referring to FIG. 2, the first to third air cushion pads 112a to 112c constituting the air cushion pad set 112 used in the heating mat having the air cell structure as shown in FIG. A lamination process is performed by thermally bonding the elastic fiber fabric 112u-1 onto the polyurethane (TPU) film 112u-2 (S11).

As the raw material used in step (S11), TPU is a rubber-like elastic body having a urethane group (-NHCOO-), which has excellent mechanical strength and wear resistance, and has excellent properties in insulation, flex resistance, colorability, and texture. The thermoplastic resin produced is suitable for clothing or coating compositions.

In addition, TPU is a non-PVC-based thermoplastic resin, which is harmless to the human body because there is no risk of generating harmful compounds, and is environmentally friendly because it does not emit air or soil pollutants during incineration.

On the other hand, conventionally, since the TPU is manufactured solely for the air cells formed on the thermal mat, the surface feels poor when directly in contact with the body, and especially in the summer, it is not only better due to sweat, but also visually good. There was a problem.

In addition, in the prior art, it was only a method of manufacturing a thin cloth-like fiber to improve the feel on the air cell 112u-3 formed by wrapping with a vinyl material, but since the cloth is difficult to integrally laminate with a TPU material, the TPU film in the present invention The elastic fiber fabric (eg, spandex fabric) is laminated by thermal bonding.

That is, an elastic fiber fabric 112u-1 corresponding to a spandex fabric or other stretchable material of the present disclosure is attached to the TPU film 112u-2 to protect areas in contact with the body. The elastic fiber fabric 112u-1 may be formed only on the air cushion pad assembly 112 among the air cushion modules 110, and constitutes the entire upper surface of the air cushion module 110 or each air cushion module 110. If the upper portion of the TPU film 112u-2, which may correspond to the circumference of the air cushion unit 112u, is heat-bonded in the form of a coin and laminated to form, unless the entire air cushion module 110 is changed Therefore, it may be manufactured by adding a sufficient shock absorbing pad to a specific body contact area.

Here, when manufacturing the TPU film 112u-2, talc may be produced by mixing talc as a raw material. Talc is a TPU film and an elastic fiber fabric are laminated to be added to improve the elongation (formability) and hydrolysis resistance, and 3 to 4 parts by weight of talc can be used with respect to 100 parts by weight of TPU.

Here, when the talc is less than 3 parts by weight, the effect of improving the dimensional stability during molding through stretching during molding of the elastic fiber fabric-attached TPU film is inferior, and when it exceeds 4 parts by weight, there is a concern that a significant decrease in mechanical strength and wear resistance is concerned.

Elastic fiber fabric (112u-1) and TPU film (112u-2) When laminating according to thermal bonding, the elastic fiber fabric and the TPU film are heated to a temperature of 140 to 200°C and a pressure of 37 to 45 g/cm ² using a pressure roller. After bonding by pressing, the resin may be formed by bonding the elastic fiber fabric 112u-1 and the TPU film 112u-2 after applying in a dot form.

The elastic fiber fabric-attached TPU film produced through this process has a total thickness of 200 µm to 1000 µm depending on the use or function, and the thickness of the elastic fiber fabric-attached TPU film is the gap between the forming rollers and the melt. It can be freely adjusted by the viscosity of the melt, and the extrusion speed of the melt.

The elastic fiber fabric-attached TPU film does not easily dismantle the elastic fiber fabric (112u-1) and the TPU film (112u-2) due to the difference in density due to warming, and is additionally subjected to lamination by thermal bonding in the form of coins. In order to be transported in one direction through a transport roller, a silicone coating layer in the form of a film is applied to the edge of the joint, so that fluidity can be suppressed.

After step (S12), each of the first to third air cushion pads 112a to 112c constituting the set of air cushion pads 112 used in a warm mat having an air cell structure by placing them in a mold and applying heat to vacuum to form a vacuum An air cell structure is formed (S12).

More specifically, embossed in the shape of a semi-spherical or egg-shaped air cushion unit 112u and a connector 115 constituting each of the first to third air cushion pads 112a to 112c constituting the air cushion pad assembly 112. Using a mold having a set of molded surfaces, a first molded body can be made by vacuum forming an elastic fiber fabric-attached TPU film, and it can be produced by attaching a thick resin and then curing it so that it can be joined with the first molded body. have. On the other hand, in the present invention, it is preferable that the connection pipe 115 has a structure in which the lower ends on the air cushioning unit 112u are in contact with each other on a horizontal surface.

After the first to third air cushion pads 112a to 112c manufactured as described above are formed of the air cushion module 110 as shown in FIGS. 3 and 4, the base member 130 is disposed with the planar heating element 120 therebetween. The body of the heating mat 100 having an air cell structure may be formed through the fastening of the sensor module set 150 when additionally manufacturing the first to third air cushion pads 112a to 112c. .

In this case, an area through which each sensor module constituting the sensor module set 150 can penetrate is previously formed on the elastic fiber fabric 112u-1, and the elastic fiber fabric 112u-1 and the TPU film 112u-2. ) After laminating, device pins corresponding to power and signal lines of each sensor module device may be formed through a punching process to penetrate the TPU film 112u-2 through the through hole.

In addition, by adding a process of applying the above-described silicon coating layer to the edge of the junction in the step (S11) of FIG. 2 through silicon for each sensor module element attached through a punching process, the fluidity of each sensor module element is suppressed. It can be done.

On the other hand, when the sensor module set 150 is formed, the first to third air cushion pads 112a to 112c of the heating mat 100 having an air cell structure may be controlled by the control device 140.

More specifically, the air cushion module 110 may further include an air cushion housing 111 and an air distribution type injection/exhaust pipe 113 in addition to the air cushion assembly 112 described above.

The air cushion housing 111 may be formed in a hexahedral shape to have a surface area (for example, 1720mm×700mm) that the patient can lie on the upper surface, and the thickness of the air cushion assembly 112 is higher than that of a conventional conventional heating mat due to the structure of the air cushion assembly 112. Although formed to be 10 to 20 mm large, it may be variably set according to the diameter of the air cushioning unit 112u of the multi-layered air cell structure.

The air cushion assembly 112 may be formed by continuously arranging the first air cushion pad 112a, the second air cushion pad 112b, and the third air cushion pad 112c as shown in FIGS. 3 and 4. The air distribution space is spaced apart from the patient's body and the air cushion housing 111 through air injection to at least one of the second to third air cushion pads 112a to 112c while the patient is lying down. It can be formed to form.

Meanwhile, in each air cushion pad 112a to 112c, the air cushion units 112u may be formed by arranging n×m (n, m are two or more natural numbers that are the same or different from each other), and an embodiment of the present invention 3 and 4 may be arranged in a grid of 8 × 4.

And, the air cushion pad assembly 112 is formed of a single-layer structure as shown in FIGS. 1, 3 and 4, or consists of an upper air cushion pad 112_1 and a lower air cushion pad 112_2 as shown in FIGS. 5 to 7. Can.

Meanwhile, each of the upper air cushion pad 112_1 and the lower air cushion pad 112_2 forms an upper space and a lower space, and the surface of the air cushion housing 111 in a default state before air is injected. It may be formed in a symmetrical shape around.

That is, the upper air cushion pad 112_1 is disposed on the upper portion of the upper surface of the air cushion housing 111, and the lower air cushion pad is disposed on the space 114 formed on the lower portion of the upper surface of the air cushion housing 111 ( 112_2) may be disposed.

Here, the structure of the air cushion unit 112u of each air cushion pad 112a to 112c constituting each of the upper air cushion pad 112_1 and the lower air cushion pad 112_2 is an elastic fiber fabric 112u-1 as described above. , TPU film (112u-2), and can be formed in the same manner as the triple structure of the air cell (112u-3).

And in another embodiment of the present invention, the structure of the air cushion unit 112u of each air cushion pad 112a to 112c constituting the lower air cushion pad 112_2 is different from the upper layer air cushion pad 112_1. 1), a functional shape forming layer (112u-2), and may also be formed of a triple structure of the air cell (112u-3).

The reason for the formation is that each air cushion pad 112a to 112c constituting the lower air cushion pad 112_2 is directly applied to the skin of the human body, unlike each air cushion pad 112a to 112c constituting the upper air cushion pad 112_1. Because it does not reach.

Hereinafter, the structure of the air cushion unit 112u of each air cushion pad 112a to 112c constituting the lower air cushion pad 112_2 will be described.

First, the surface film 112u-1 is an area corresponding to an outer shell formed of the same material as the base member 130, and is formed by wrapping the functional form forming layer 112u-2 therein, and the functional form forming layer 112u-2. The air cell during air injection of the upper air cushion pad 112_1 and the lower air cushion pad 112_2 by mixing a gel or latex inside the silver surface film 112u-1 with a functional additive for generating far infrared rays and anions. It can improve the morphological stability of 112u-3) and impart body vitality.

In the present invention, the gel may be formed by using a cooling gel material as a main substrate, and a cold and hot element is connected to the control device 140 inside the functional form forming layer 112u-2 to form a functional form forming layer by the control device 140 ( The cooling for 112u-2) can be controlled.

On the other hand, in the present invention, by forming a latex sheet formed of a latex material in addition to the cooling gel material or a polypropylene sheet formed of a polypropylene material through lamination of a foam type, morphological stability can be improved.

Here, after applying the cooling gel to form the surface film 112u-1, the cooling gel coating layer is coated with a latex resin or polypropylene resin, and a preset time at a temperature of 30°C to 70°C at a preset temperature, 30 After natural fermentation for 2 minutes to 2 hours, the viscosity is increased to further form a latex resin or a polypropylene resin, followed by high-frequency heating to bond the cooling gel layer, two or more layers of latex resin or polypropylene resin layer. have.

In addition, the first layer of latex or polypropylene resin in the present invention may include functional additives for at least one or more far infrared rays, anion generation, etc., selected from the group consisting of ocher, jade, activated carbon, charcoal, and pulverite powder, Through this, it is possible to implement a functional mat.

The air cell 112u-3 may be formed in a structure in which gases injected with each other can communicate through the surface film 112u-1 and the parallel extension tube 115 formed in the functional shape forming layer 112u-2. . The air cell 112u-3 is disposed in a matrix form so that the gas can be smoothly communicated through the parallel extension pipe 115, so that the first air cushion pad 112a and the second of the lower air cushion pad 112_2 are disposed. The first air cushion pad 112a, the second air cushion pad 112b, and the third air cushion pad 112c of the upper air cushion pad 112_1 in each of the air cushion pad 112b and the third air cushion pad 112c, respectively. ) In addition to preventing damage to the air cell structure of the multi-layered air cell structure according to the upper pressure in each, it is possible to stably provide the effect of accommodating the body part of the intestine.

In particular, the lower air cushion pad 112_2 may be formed in a space 114 formed on a lower portion of the upper surface of the air cushion housing 111, where the space 114 is formed as an empty space or an air cell 112u. In accordance with the expansion of -3), the volume may be formed of a gel or latex material having an adjustable volume within the space 114.

The density of the space 114 when the volume is formed of a gel or latex material with respect to the space 114, the first air cushion pad 112a and the second air cushion pad constituting the lower air cushion pad 112_2. (112b), by forming a lower density than the gel or latex material used to form the surface film 112u-1 of the third air cushion pad 112c, the first air cushion pad 112a, the second air cushion There is a feature that can adaptively respond to the flow of the air cushioning unit 112u of the pad 112b and the third air cushion pad 112c.
