The present invention is an elastic foam sponge cushion support layer through the primary mold as a gel material having a stickiness as a manufacturing method applicable to air cushions, air tube products used in beds, shoe insoles, toys, sports goods, automobile tires, etc. It relates to a method for producing an elastic foam sponge cushion support layer formed by forming a sponge cushion support layer to surround the entire sponge cushion support layer again with a sticky gel tube layer.

In the present invention, the adhesive gel is a phenomenon in which a polymer gel by a bridge bond takes a three-dimensional network structure and becomes insoluble in a solvent, and becomes a sticky gel after a certain time through a chemical reaction. In particular, the surface is tacky and excellent in elasticity. As a result, once the shape is deformed or compressed, even if the shape is crushed or compressed, there is an elasticity that is restored to its original shape when the compressive force disappears.
This adhesive and highly elastic gel (Gell) as a material wraps the elastic foam sponge support layer already formed through the primary mold to a certain thickness. Subsequently, it is transferred to the secondary mold and fixed to the fixing pin mounted on the secondary mold, and then embedded. Then, the adhesive is injected into the secondary mold to inject the adhesive gel (Gell). Gell) It is formed by the secondary mold to be enclosed by the tube layer to be sealed, and then the adhesive gel formed from the secondary mold through the third mold by covering the cover layer with rubber or soft synthetic resin, or leather or fiber. It is molded to fit the shape of the surface of the Gell tube layer, and the formed cover layer is pressed onto the Gell tube layer surface, and the outer circumferential surface of the cover is sealed with an adhesive or sewing to obtain an adhesive characteristic. The present invention relates to a manufacturing method for forming a cushion layer having an elastic sponge cushion support layer embedded in and bonded to a gel tube layer.

Usually, it is widely used as cushioning material or air tube material by using rubber, soft PVC, polyurethane (TPU) sheet as a means of air blocking of air products, but it is generally used for bed or shoe insole cushion products. In this case, there is a defect that the elastic difference between the heavily loaded body part and the unbalanced part is unevenly severely acted, and due to many inconveniences in use, it was impossible to obtain a product that satisfies the expectation.

In order to achieve a soft cushioning and a balanced cushioning effect, the conventional manufacturing method, such as the biased pull phenomenon due to the load is remarkable, and to compensate for this, if the air volume is full, the air cushion feel is insignificant. Injecting a fluid into the liquid, but the rapid flow of the fluid causes a lot of fluctuations, which is not a suitable solution to the fundamental problem of air products.

The present invention eliminates the drawbacks of air cushion products as described above, and the nonuniformity of elasticity caused by the effects of slack and biasing and climate or temperature caused by filling only with air in the air blocking material which is a general feature of air cushion products. Unlike the conventional method of filling the air cushion layer with air only to solve the deformation and deformation, the elastic foam sponge cushion support layer is interposed to distribute the load evenly when the body is loaded and to provide a stable and uniform cushioning feeling.

In addition, in the case of bed or shoe insole, the softness of gel makes skin feel good.

In the case of general air products, once punctured, the product must be repaired, replaced or disposed of. However, the present invention has a sticky gel tube layer, and thus it is not a puncture by a knife or nail. Even after puncture, the gel tube layer is restored to its original state, and the air is shut off, which is a breakthrough manufacturing method that completely eliminates the problems of existing air products.

In order to achieve this purpose, the elastic foam sponge support layer 10 is molded to suit the purpose of the product, and the molded elastic foam sponge support layer 10 has a sticky gel tube layer 11. The entire surface of the elastic sponge cushion support layer 10 is enclosed and encapsulated to be sealed, and the surface of the combined gel tube layer 11 is pressed with leather, fiber, rubber, soft synthetic resin, or the like. Elastic layer configured to be sealed with a sticky gel tube layer 11 having an air barrier gel tube having a constant thickness. Sponge cushion support layer 10

Preferred embodiments of the present invention will be described in detail with reference to the drawings.

1 is an elastic foam sponge cushion supporter layer 10 having a supporter surrounded by a sticky gel tube layer 11 having a cover according to a first embodiment of the invention. Is a partial incision perspective

2 is a partial cross-sectional view.

The elastic foamed sponge cushion supporter layer 10 molded according to the use of the product is molded and the gel tube layer 11 sticking to the molded elastic foamed sponge cushion supporter layer 10 is formed. The surface of the elastic foam sponge cushion support part layer 10 by injecting a gel is surrounded by a sticky gel tube layer 11 in which the entire surface of the elastic foam sponge cushion is maintained at a constant thickness. The band is integrally formed with the gel tube layer 11 and is bonded and formed, and the surface of the molded gel tube layer 11 may be made of leather, fiber, or rubber. Cover with a cover 12 material, such as a soft synthetic resin to be pressed and sealed, and the air is blocked and sealed by the sticky gel tube layer 11, so that the elastic foam sponge cushion support layer 10 It is to constitute a cushion layer having a).

The elastic foam sponge cushion support layer 10 may be made of polyurethane resin or elastic foam resin.

In addition, the elastic foam sponge cushion support layer 10 may be molded into various shapes, such as a flat shape, a circular shape, and other curved protrusion shapes to suit the purpose of the product, and according to the shape of the elastic foam sponge cushion support layer. The adhesive gel tube layer 11 may also have various shapes.

In order to seal the surface of the gel tube layer 11, the gel is preferably manufactured through a sticky gel.
In the present invention, the gel tube layer 11 has a high adhesiveness in itself. Therefore, when this is exposed to the outside as it is, the adhesive adheres to various foreign matters floating on the outside here, and after a certain period of time, it is difficult to use hardly contaminated. Therefore, when used as a person's shoe insole, there is also a property that directly contact the person's soles, and some of the properties are severely degraded. Therefore, in the present invention, the outside of the gel (tube) layer (11) is wrapped in leather, synthetic leather, artificial leather, natural sandpaper, and the like to improve the usability, and at the same time to prevent contamination of foreign materials.

According to the present invention, the elastic foam sponge cushion supporter layer 10 is formed therein, and the elastic foamed sponge cushion supporter layer 10 is provided with numerous bubbles layers having a constant pressure therein.
When the pressure is applied from the outside of the bubble layer is crushed while absorbing the air contained in the bubble layer to the outside. When the pressure on the bubble layer disappears again, the original form is restored. However, in the case of the present invention, the resilience is wrapped in a gel tube layer 11 having a high adhesiveness and elasticity. As a result, the air in the bubble layer does not discharge to the outside due to the pressure on the bubble layer and remains in the bubble layer as it is.
The air remaining in such a bubble layer eventually exhibits a good elasticity when used in various applications such as shoe insoles, chair supports, and the like, after the bubble layer serves as a kind of air spring.
In addition, the elasticity and adhesiveness of the gel tube layer 11 may be relatively weak in the case of a shoe insole used by a person (about 250 to 300 kg / cm 2), but may be severe as in an automobile or other sports equipment. When pressure is applied, the elasticity is adjusted so that it is bonded to the necessary purpose.
In addition, since the gel tube layer 11 is composed of a semi-solid gel in the form of a gel, there is no tearing or pinhole generation even if it is punctured by a needle.
