The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Terms such as those defined in commonly used dictionaries are to be interpreted as having a meaning consistent with the contextual meaning of the relevant art and are not to be construed as ideal or overly formal in meaning unless expressly defined in the present application .

First, as a first embodiment of the present invention, any one of the latex (Latex) and the solid-state bonding target member of the liquid NBR (Nitrile Butadiene Rubber), SBR (Styrene Butadiene Rubber), NR (Natural Rubber) It is made by the method of processing and attaching.

That is, any one of the above NBR, SBR, and NR on the solid-state joining target member selected from any one or more of synthetic fibers, microfilm, gauze, fibers, polyurethane, sponges, rubies, and synthetic resin materials. Liquid latex (Latex) is applied to a constant thickness and then steam heated in a steam machine for a temperature of 90 ~ 120 ℃ and 30 ~ 60 minutes to solidify the liquid latex (Latex) as well as the target of the solid state It is made by joining integrally with the member.

When the steam is heated at a temperature of 90 to 120 ° C. and a time of 30 to 60 minutes in the steamer, the latex becomes a liquid and penetrates to a certain depth (0.3 to 0.9 mm) into the tissue of the member to be bonded in a solid state. Since the solidified while being solidified, the object to be bonded in the solid state and the solidified latex (latex) is integrally bonded.

Therefore, the present invention as described above can be bonded without the need for a separate adhesive to increase the bonding strength without adversely affecting the human body and to improve the workability by reducing the work process during manufacturing, as well as significantly reducing the cost of materials to reduce the production cost It can be provided at a price, thus maximizing competitiveness.

In addition, the latex (Latex) portion is excellent in the cushion and elasticity and the touch of the skin, combined with a ruby cell or micro film, etc. can be used as a cosmetic auxiliary materials such as puffs or cosmetics, or fibers, gauze, polyurethane, etc. It can be used as a material for various purposes such as immersion products, carpet packing, building materials, etc. in combination with synthetic resin.

Next, a second embodiment of the present invention will be described with reference to FIGS. 2 to 4.

First step (S1)-A step of mounting the joining member (1) in the solid state to the forming mold (T) by inserting the joining member (1) in the solid state into a forming mold (T) formed in a uniform shape evenly. Mount it.

The member 1 to be bonded in the solid state is selected from any one of synthetic fibers, microfilm, gauze, fibers, polyurethane, sponges, rubels, and synthetic resins.

The second step (S2)-is a step of applying a latex (Latex) (2) of the liquid, in the first step in the solid state to be bonded to the member 1 in the solid state NBR (Nitrile Butadiene Rubber), SBR (Styrene Butadiene) Rubber), NR (Natural Rubber) of any one type of latex (Latex) (2) is applied to a predetermined thickness.

The predetermined thickness to be applied as the liquid latex (Latex) 2 is determined to an appropriate thickness depending on the application.

Third Step (S3)-A step of uniformly and smoothly applying the latex (Latex) 2 applied in the liquid phase to the squeegee bar (Squeeze bar) of the latex (Latex) 2 applied in the second step By (3), it is made uniform and flat to a certain thickness.

The inclination angle of the squeegee bar 3 is preferably set to 45 °.

Fourth step (S4)-The liquid latex (Latex) (2) is solidified, and the step of forming by bonding integrally with the bonding object member (1), the liquid latex (Latex) (2) in the third step Is heated to a predetermined temperature and time by steaming (T) the forming mold (T), which has been uniformly and flatly finished to a certain thickness, to solidify the liquid latex (Latex) 2 and to be bonded. It is molded integrally with the member.

It is preferable that the said heating temperature shall be 90-120 degreeC, and heating time shall be 30-60 minutes.

When the heating temperature is 90 ° C. or lower, the liquid latex does not solidify well, and when the temperature becomes 120 ° C. or higher, the solidification becomes rapid and solidifies even before sufficient penetration into the tissue of the member to be bonded is performed.

If the heating time is 30 minutes or less, the liquid latex does not solidify well, and thus the bonding with the member to be bonded is not performed. If the heating time is 60 minutes or longer, wrinkles are generated in the solidified latex, and unnecessary electric use and manufacturing time are prevented. Waste.

As described above, when the steam is heated at a temperature of 90 to 120 ° C. for a time of 30 to 60 minutes, the latex in a liquid phase has a predetermined depth (0.3 to 0.9 mm) as a tissue of a member to be joined in a solid state. As a result of infiltration and solidification, the object to be joined and the latex in a solid state are integrally bonded.

The fifth step (S5)-extracting and cooling the forming mold (T) from the steamer (4) in the fourth step to solidify the liquid latex (Latex) as well as integrally bonded to the bonding target member and completed molding The mold T is extracted from the steamer 4 and cooled at room temperature.

Sixth step (S6)-A step of cutting into a required shape of the article, the molded article cooled in the fifth step is extracted from the mold (T), the article of the required form (m) by the punch (p) in the die (d) Finish by cutting).

As described above, the present invention as described above does not have a bad influence on the human body as described above, since the bonding object member 1 and the solidified latex (Latex) 2a are integrally bonded without a separate adhesive as shown in FIG. 3. It improves the binding force and reduces the working process during manufacturing, which improves the workability, and greatly reduces the production cost, thus reducing the production cost, and thus can be provided at a low price, thus maximizing competitiveness. ), Carpet packing, building materials (建材) can be used for a variety of applications.

Next, as a third embodiment of the present invention, as shown in FIG. 3, any one of latex (Latex) 2a of Nitrile Butadiene Rubber (NBR), Styrene Butadiene Rubber (SBR), and Natural Rubber (NR) (1) consists of articles integrally joined together.

As described above, the third embodiment of the present invention adversely affects the human body as described above, since the bonding target member 1 and the solidified latex 2a are integrally bonded without the need for a separate adhesive as described above. It can improve the bonding force and reduce the work process during manufacturing to improve the workability, and can greatly reduce the production cost and reduce the production cost, thereby providing the low price, thus maximizing the competitiveness, and the latex part It is excellent in cushion and elasticity and feels by skin contact. When combined with ruby cell or micro film, it can be used as cosmetics auxiliary material such as puff as cosmetic tool. Also, it can be combined with synthetic resin such as fibers, gauze and polyurethane. It can be used as a material for a variety of purposes such as 浸漬 製品), carpet packing, building materials (建材).
