Description

A production and processing technology of combining rubber inserts with leather or cloth

technical field

The invention relates to the technical field of rubber product processing, in particular to a production and processing technology in which rubber inserts are integrated with leather or cloth.

Background technique

The use of rubber has a long history and is widely used in tires, shoe soles, trademarks and other fields. In the structure of the rubber products of the soles and trademarks, they are all composed of a layer of rubber base material with rubber inserts. It is only the rubber inserts that reflect its functionality, and the rubber base material only plays a role in connection. Therefore, there is a kind of rubber insert that is arranged on the leather or cloth product, which uses leather or cloth to replace the rubber bottom material, reduces the use of rubber materials, and makes the product more portable. In the production of rubber inserts and leather or cloth, the production process is generally to apply glue on the processed rubber inserts and leather or cloth, and then simply attach the two together , the rubber insert produced by this process is not very tightly combined with the leather or cloth, and the insert is easy to fall off. The rubber insert mainly reflects the functional characteristics of the product, so the falling off of the insert causes the product to be scrapped. The service life of the product is greatly reduced.

Contents of the invention

The purpose of the present invention is to provide a kind of rubber insert and leather or cloth which is closely and firmly combined with rubber insert and leather or cloth, and which is easy to produce and manufacture. The production and processing technology of combining leather or cloth.

To achieve the above object, the present invention adopts the following technical solutions:

a, material preparation: add a vulcanization accelerator to the rubber raw material, wherein the vulcanization accelerator accounts for 0.8-2% of the total weight, and mix evenly with a roller machine;

b. Tablet production: Press the prepared mixed material powder into a 0.5-1.0mm sheet in a roller press;

c. Spreading: Press and lay the prepared sheet material layer by layer on the separate mold cavity in the insert mold, compress the sheet material in the mold cavity, and pave the sheet material on the upper surface of the mold cavity; The temperature is controlled at 50-150°C;

d. Hot pressing molding: place the mold with the laid sheet on the template at 100-170°C for press molding, adjust the pressure at 50-150 kgf, and control the time at 4-7 minutes. block fetch;

e. Insert shaping: Remove defective products from hot-pressed inserts, remove batch fronts and shape them;

f. Cloth filling inserts: the shaped inserts are arranged and filled in an insert cavity set by a fit mold;

g. Gluing: Apply adhesive to the insert of the insert cavity;

h. Paving material: After applying the adhesive, lay a piece of leather or cloth above the cavity of the insert that fits the mould;

i. Hot pressing lamination: Put the laminating mold with leather or cloth on the template at 100-170°C to press lamination, adjust the pressure at 50-150 kgf, and control the time at 4-7 minutes. Take it out after the block fits tightly with the leather or cloth.

Wherein, in the material preparation process, when configuring the mixture powder, the color rubber raw material is mixed into the rubber raw material to prepare the required color.

The beneficial effect of the present invention lies in that: in the production process of the present invention, the inserts are taken out after material preparation, sheeting, hot-press forming, and then shaped, and the shaped inserts are arranged and filled in an insert cavity set by a lamination mold , paint the adhesive on the insert of the insert cavity, after applying the adhesive, lay a piece of leather or cloth above the die cavity of the fitting mold; put the fitting mold with the leather or cloth on 100-170°C template is pressurized and bonded, the pressure is adjusted at 50-150 kgf, and the time is controlled at 4-7 minutes. After the insert is tightly bonded to the leather or cloth, it is taken out. In the processing technology of the present invention, After the insert is formed, it is placed in the laminating mold. Under the action of high temperature, high pressure and adhesive, the rubber insert is tightly combined with the leather or cloth, and it is not easy to fall off, which prolongs the service life of the product.

Detailed ways

Below in conjunction with accompanying drawing 1, the present invention will be further elaborated:

A production and processing technology for combining rubber inserts with leather or cloth, which includes the following process steps:

a, material preparation: add a vulcanization accelerator to the rubber raw material, wherein the vulcanization accelerator accounts for 0.8-2% of the total weight, and mix evenly with a roller machine;

b. Tablet production: Press the prepared mixed material powder into a 0.5-1.0mm sheet in a roller press;

c. Spreading: Press and lay the prepared sheet material layer by layer on the separate mold cavity in the insert mold, compress the sheet material in the mold cavity, and pave the sheet material on the upper surface of the mold cavity; The temperature is controlled at 50-150°C;

d. Hot pressing molding: place the mold with the laid sheet on the template at 100-170°C for press molding, adjust the pressure at 50-150 kgf, and control the time at 4-7 minutes. block fetch;

e. Insert shaping: Remove defective products from hot-pressed inserts, remove batch fronts and shape them;

f. Cloth filling inserts: the shaped inserts 2 are arranged and filled in the insert cavity 11 provided by a lamination mold 1;

g. Gluing: apply adhesive on the block 2 of the block cavity 11;

h. Paving material: After applying the adhesive, lay a piece of leather or cloth 3 above the insert cavity 11 of the fitting mold 1;

i. Hot pressing lamination: Put the laminating mold 1 with leather or cloth on the template at 100-170°C to press and laminate, adjust the pressure at 50-150 kgf, and control the time at 4-7 minutes. The insert is taken out after it fits tightly with the leather or cloth.

In the material preparation process, when configuring the mixed material powder, mix the color rubber raw material into the rubber raw material to prepare the required color, so that colored inserts can be produced to meet the needs of product design.
