The present invention relates to a method for forming, modeling and designing a silicon gum.

In the present invention, the first step of engraving the required pattern on the metal plate intaglio, mixes the pigment of the desired color, mixes a predetermined amount of silicone and curing agent and color-adjusted pigment to fill the syringe, the pattern engraved intaglio by applying pressure In the second step of injecting into the vacuum pump, the third step of removing the air bubbles by leaving it in a vacuum container for a few minutes in a proper state, taking out of the vacuum degassing machine, cleaning the metal plate and laying it on the fabric or leather surface to be planted and applying pressure In the fourth step of attaching, the metal plate is peeled off so that the pattern is separated and adhered to the surface of the fabric, and the fifth step is left to solidify by standing for several minutes.

Description

Molding-model and design manufacturing process using silicon gum

The present invention relates to a molding, model and pattern manufacturing method using a silicon gum, in particular, unlike the conventional model and pattern material containing PVC and rubber containing environmental hormones and dioxin, by adopting silicon gum as a pollution-free material Various moldings can be produced, and it is designed to plant patterns on clothing fabric leather and various materials.

Conventionally, since the bubble generated when mixing the pigment during the production of silicone gum cannot be effectively removed, the productivity is very low due to the defective rate of 40%.

SUMMARY OF THE INVENTION The present invention has been made to solve such a conventional drawback, and an object of the present invention is to leave a bubble in a vacuum under reduced pressure for several minutes to remove a silicon gum bubble having a high viscosity, thereby reducing the defect rate to 0.5%. It is to provide a molding, model and pattern manufacturing method used.

1 is an operation flowchart of the present invention.

Hereinafter, an embodiment of the present invention will be described with reference to FIG. 1, which is an operation flowchart.

The present invention describes, for example, the case of planting patterns (letters and logos) on various clothes, accessories, hats, fabrics, leathers, and sculptures.

First, the engraved pattern is engraved on a metal plate, such as aluminum or a new column, in engraving (step S1).

After mixing the pigment of the desired color (step S2), the silicone compound is injected into the engraved pattern while pressurizing by injecting a mixture of 6-10% of the mixture of silicone and the curing agent and the color-controlled pigment into a syringe. (In case of sculpture, it is injected into the casting) (S3 step).

The vacuum pump is then left in an appropriate vacuum container (vacuum deaerator) for several minutes (for a few minutes, for example) to remove bubbles. When the container is in a vacuum state, it gradually starts to escape from the air around the silicon. Eventually, all the air in the container is released and the bubbles in the silicon gum are completely removed (defoaming).

In this way, the bubble is removed from the vacuum deaerator, the metal plate is wiped clean, and then placed on the surface of the fabric (or leather, non-woven fabric) to be planted and applied by applying pressure (S4 step).

At this time, heat may be added to shorten the curing time. Then, when the metal plate is removed, the silicon compound is cured, and the formed pattern comes off and adheres to the surface of the fabric (if the molded form is removed), and then left to stand for several minutes to solidify (steps S5 and S6).

According to the present invention, the defect rate can be lowered to 0.5% by allowing the bubbles to stand for several minutes under a vacuum depressurization state to remove (defoaming) the bubbles of the high-density silicon gum by the above-described process. The present invention is not limited to the above embodiment, and can be applied to a wide variety of fields because of the friction resistance, the touch superiority, and the non-toxicity (dioxine-free at incineration), which is a characteristic of silicon.

That is, it can be applied to various molded products requiring a soft touch, a second place where friction resistance is required, a third vacuum sticker, a fourth car wiper, a fifth environmental hormone and various containers for releasing dioxins upon incineration, baby products, toys, and the like.

In the case of various molded products requiring the first soft touch, for example, keyboard keyboards (various computer hardware, calculators, telephones, etc.), key chains or various handles (leather extension tools, zippers, bats, kitchen utensils, automobiles) It can be used for other handles). In the case where the second frictional resistance is required, various handles (ballpoint pen, zipper, key, doorknob, bag handle), inside the back pocket of the wallet (to prevent spillage), the inside of the pants belt (to prevent the jacket from falling out), Inside the shoulder strap (no spill), wallet cuticle, hat inside, sock bottom, inside gloves, shoe sole and insole, baseball glove, tableware bottom, zipper handle outside wallet cutout, inside hat, socks bottom, inside gloves, new outsole And insoles, baseball gloves, tableware bottoms, zipper handles, and the like.

The present invention as described above has a result as shown in Table 1 when compared with the prior art.

In the present invention as described above, by leaving the bubble under vacuum depressurization for several minutes to remove the bubbles of the high viscosity silicone gum to reduce the defect rate to 0.5% by adopting the silicone gum as a pollution-free material, it is possible to manufacture a variety of moldings, clothing fabric The effect can be planted on leather and other materials.

Further, according to the present invention, the elasticity is very excellent, the washing friction is strong, and the friction resistance is very excellent.
