Abstract

PURPOSE: A method for manufacturing an elastic sponge type cushion supporting layer engaged with a gel tube having adhesive property is provided to form the elastic sponge type cushion supporting layer in various shapes corresponding to the usage of the product. CONSTITUTION: An elastic sponge type cushion supporting layer(10) is firstly formed with a first sponge mold. The elastic sponge type cushion supporting layer is delivered to a second mold for forming a gel tube layer(11) having the adhesive property and fixed into the second mold with a pin. Gel materials to have the adhesive property by a chemical reaction are inserted into the second mold containing the elastic sponge type cushion supporting layer. The surface of the elastic sponge type cushion supporting layer bonds to the gel tube layer.

Description

A method for preparing an elastic sponge cushion support layer combined with a sticky gel tube.

The present invention is an elastic foam sponge cushion molded through a primary mold of 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. The support layer is made of a sticky gel tube layer so that air is blocked by a sticky gel tube layer formed through a secondary mold to surround the entire surface of the elastic foam sponge cushion support layer. Regarding the manufacturing method of the elastic foam sponge cushion support layer

More specifically, the polymer gel by the bridge bonds takes a three-dimensional network structure and becomes insoluble in the solvent. After a certain period of time through a chemical reaction, the gel becomes a sticky gel. Using this adhesive gel (Gell) as a material, the elastic foam sponge support layer formed by the primary mold is transferred to the secondary mold to be fixed to the fixing pin mounted on the secondary mold, and then embedded. After the adhesive gel is injected into the mold, the entire area around the surface of the elastic sponge cushion support layer is molded through the secondary mold to be enclosed by the adhesive gel tube layer, and then rubber or soft. The cover layer is made of synthetic resin, or leather or fiber to conform to the shape of the sticky gel tube layer formed in the secondary mold through the third mold. Stripped Gel (Ge ll) Compress the tube layer surface and seal the outer circumferential surface of the cover with adhesive or sewing to form a cushion layer having an elastic sponge cushion support layer embedded in a sticky gel tube layer. It relates to one manufacturing method.

Generally, 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 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 way to solve 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 a general air product, it was a one-time product that had to be repaired, replaced, or disposed of when puncture occurred. 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 the above object, the elastic foam sponge cushion supporter layer 10 is molded into a primary sponge mold according to the use of the product, and the molded elastic foam sponge supporter layer 10 is made of a gel tube having an adhesive property ( tube 11 to form a secondary mold so that the entire surface of the elastic sponge cushion support layer 10 is enclosed and sealed, and the surface of the combined gel tube layer 11 is made of leather or fiber. Or a cushion layer which is pressed and sealed by rubber or soft synthetic resin, etc., the cushion layer having a sticky gel tube layer having an air barrier gel tube having a constant thickness. 11) is an elastic foam sponge cushion support layer 10 configured to be sealed with

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

2 is a partial cross-sectional view.

Through the foam sponge mold, the elastic foam sponge cushion support part layer 10 molded according to the use of the product is molded into the primary mold, and the fixed cushion pin is mounted inside the secondary mold. Elastic foam sponge cushion by injecting a sticky gel to the secondary mold to be fixed to the secondary mold, and then to form a sticky gel tube layer 11 after embedding The support layer layer 10 is surrounded by a sticky gel tube layer 11 in which the entire surface has a constant thickness. 11) The surface of the gel tube layer 11, which is integrally formed and bonded to the molded adhesive, is covered with a cover 12 material such as leather, fiber, rubber, or soft synthetic resin. Cover and press seal and air is blocked by the sticky gel tube layer 11 One will ever hameuroseo and sealed configuration such that a cushion layer of an elastic foam sponge cushion support layer 10.

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 a shape having a variety of three-dimensional feeling according to the use of the product, for example) can be molded into a flat shape, a circular shape, other curved protrusions, etc. of the elastic sponge cushion support 10 According to the shape, the gel tube layer 11 which is tacky may have various shapes.

In order to seal the surface of the gel tube layer 11, the gel is preferably manufactured through a sticky gel.
