Description

A manufacture method of soundproof for an automobile}

The present invention relates to a method for manufacturing a sound insulation board of a ceiling or side wall and a door of a vehicle.

In automobiles, especially diesel vans and straws, to prevent engine noise and noise from outside, a plate filled with sponge or soundproof material is separately formed on the inner wall of the vehicle. And the coating leather, etc. are piled up to form a soundproof structure that can be equipped with various noise blocking, dustproofing, insulation and interior effect generated from the engine and the outside at the same time.

As mentioned above, the soundproofing structure is widely used for the purpose of blocking noise from the engine or the outside in order to obtain a comfortable and stable driving environment. It is composed.

This conventional soundproof structure is attached to the plate of the ceiling or door cut as described in Korean Patent Publication No. 5144, Unregistered Patent No. 120303, and a sponge and coating cut to the same size on the back side of the plate The silver foil insulation material and the coated leather, which are attached by attaching a leather, form pin holes at regular intervals and attach and fasten the button holes to the pin holes to form a soundproof board member as a fixing means in which the button portion is recessed.

This construction combines the insulation and heat prevention, plate, sponge and leather in a relaxed state, and the noise blocking effect is extremely bad. In addition, a large number of pin holes are drilled through a large shape and the button pin is passed through to combine the button pins. It is a very bad disadvantage of workability because it requires a lot of work time and manpower as it is made by manual work, and there is a problem that the aesthetic design can not be enhanced due to the problem of uniform production and the limitation of quantity. .

The present invention is to improve the above problems, in particular by laminating and gluing the plate, textile paper and sponge, leather integrally by the press work to increase the noise effect and the manufacturing process is simple and easy to manufacture mass production It is an invention for the purpose of increasing the value of the product by the interior effect for creating the atmosphere in the vehicle as well as the feature that can increase the value of the product by forming a variety of shapes by the mold to have a friendly in industrial competition.

First embodiment

As shown in the above, the upper and lower molds (1) and (2) that match the ceiling or door are laminated with the paper 10 and the sponge 20 and the leather 30 having a thickness of about 10 mm. 1) (2) is pressurized by the press machine to the weight of about 40-50 kg by heat of about 60-100 degree for about 5 minutes.

Accordingly, the laminated fabric paper 10, the sponge 20, and the leather 30 are compressed by the protrusions 3 of the mold, and the sponge 20 and the leather 30 are melted on the fabric paper 10 by high heat. In addition, the concave portion 4 is inflated by the sponge 20 layer without being pressurized.

Second embodiment

Lay the sponge 20 and the leather 30 of about 10 mm thickness on the upper mold (1) and the lower mold (2) to match the ceiling or door, and the upper mold (1) is heated by a press to about 60 to 100 degrees. Pressurize at 40 ~ 50kg weight for about 5 minutes.

Accordingly, the laminated sponge 20 and the leather 30 are pressed by the protrusions 3 of the mold, and the sponge 20 is melt-bonded with the leather 30 by high heat.

Third embodiment

The melting means may be performed at a known high frequency to melt-bond the fabric paper 10, the sponge 20, and the leather 30, or melt-bond the sponge 20 and the leather 30.

By attaching the member configured as described above to the ceiling plate member 9 or the door plate member, the plate member is fastened to the ceiling or the door of the vehicle to constitute the soundproof plate member.

In addition, the lower die 2 may be a plate-shaped die that serves as a flat plate.

Reference numeral 8 denotes a soundproof board, and 7 denotes a pattern shape.

Detailed embodiments according to the above process of the present invention will be described.

Referring to the process of the first embodiment in detail as follows.

1st process

The upper and lower molds (1) and (2) matching the ceiling or the door are installed in a known press, and the fabric paper 10, the sponge 20, and the leather 30 are sequentially stacked.

At this time, it is preferable that the sponge has a good thermal insulation effect and uses materials of fire prevention, dust prevention, and noise blocking effect that are not burned, and the thickness can be selected and used to increase the effect.

2nd process

When the upper and lower molds (1) and (2) are pressed at a weight of about 40 to 50 kg for about 5 minutes with a heat of about 60 to 100 degrees, the lower portion of the protrusions 3 of the mold is lowered and pressed by the mold (30). ) And the sponge 20 is melt-bonded to the leather (bottom) fabric paper 10 while being compressed to shape the shape.

At this time, if the heat is high, the pressurization time may be reduced and the time may also be reduced.

3rd process

The member formed in the second process is attached to the ceiling plate member 9 or the door plate member.

That is, an adhesive is applied to the ceiling plate member 9 and the fabric surface of the member formed by the above process is attached thereto. As a result, the sound insulation board 8 is attached to the ceiling plate member 9.

4th process

The soundproof plate is constituted by fastening the member of the third step to the ceiling of the vehicle.

The process of the second embodiment of the present invention will be described in detail.

1st process

The sponge 20 and the leather 30 having a thickness of about 10 mm are laminated on the upper mold 1 and the lower mold 2 that match the ceiling or door.

2nd process

The sponge 20 and the leather 30 laminated by pressing the upper mold 1 with a weight of about 40 to 50 kg in a heat of about 60 to 100 degrees with a press machine are pressed by the protrusions 3 of the mold. And the sponge 20 is melt-bonded with the leather 30 by high heat.

3rd process

The member formed in the second process is attached to the ceiling plate member 9 or the door plate member.

4th process

The soundproof plate is constituted by fastening the member of the third step to the ceiling of the vehicle.

The process of the second embodiment of the present invention will be described in detail.

1st process

Laminate the fabric 10 and the sponge 20 and leather 30 of about 10mm thickness on the lower mold (2)

2nd process

In the laminated state, a known radio frequency is injected to melt-bond the fabric paper 10, the sponge 20, and the leather 30, or melt-bond the sponge 20 and the leather 30 without the fabric paper 10.

3rd process

The member formed in the second process is attached to the ceiling plate member 9 or the door plate member.

4th process

The soundproof plate is constituted by fastening the member of the third step to the ceiling of the vehicle.

Accordingly, it is possible to simultaneously have interior effects together with external noise blocking, dustproofing, thermal insulation, and safety of the vehicle, and the uneven shape and elasticity of the sponge 20 and the coating leather 30 not only produce a cozy atmosphere inside the vehicle. Even in an accidental abrupt accident due to the impulse can be expected a safety effect because of the thick cushion of the sponge (20) and does not catch fire even in the fire will have the effect of increasing the safety.

And by forming a variety of irregularities of the mold to form a pattern (7) of various forms on the ceiling to increase the direction and aesthetic effect of the more comfortable atmosphere in the car to fit the driver's personality.

As described above, the present invention is intended to simplify the production of soundproof board material for the safety of the rollover accident together with the engine noise of the automobile and various noises from the outside, solar thermal cutoff, ground heat cutoff, and engine heat cutoff. It is a mold that provides the aesthetic effect of the pattern generated by the fixing means by the fusion bonding part and the manufacturing process can be made extremely simple. The interior effect together with the noise blocking, dustproofing, thermal insulation and safety It is a useful invention that can be mass-produced at a simple and inexpensive production price by providing a method of melt-bonding to the fabric paper by pressing the leather and the sponge laminated by the upper and lower molds so as to have the same.
