DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a door lining,
The present invention relates to a surface covering material for a vehicle component provided as a roof panel, an instrument panel, and the like, and a method for manufacturing the vehicle component.

[0002]

2. Description of the Related Art In general, some of the above-mentioned vehicle components are constructed by using a fabric having a high elongation such as a moquette or a soft weave as a surface material.

[0003] Conventionally, when the cloth is used as a surface material, in order to prevent the pile from coming off, curving, and meandering, a back coat material such as an acrylic emulsion is formed on a back side in advance at a stage of a cloth before being formed into a desired three-dimensional shape. A back coat layer is provided by coating. In addition, the back coat layer is formed into a desired three-dimensional shape by using a fabric provided on the back surface side.

However, when the fabric provided with the back coat layer is formed into a three-dimensional shape, even if a moquette, a soft weave, or the like is rich in elongation, the elongation of the back coat layer is low. And only about 2% elongation can be obtained. For this reason, it is not only difficult to form a desired three-dimensional shape, but also molding defects are likely to occur.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to improve the formability of a surface covering material to prevent the occurrence of molding defects and to efficiently form a desired three-dimensional shape as a surface covering material or a vehicle mounting member. It is an object of the present invention to provide a method for manufacturing a facing material and a vehicle component.

According to a first aspect of the present invention, there is provided a method of manufacturing a surface covering material for a vehicle exterior member, wherein a fabric having a high elongation such as a moquette or a soft weave is used as a surface exterior material for the vehicle exterior member. After shaping the surface covering material into a desired three-dimensional shape with a molding die, the back coating material is spray-coated on the back surface of the surface mounting material while the surface covering material is held by the molding die. The material is dried by heating with a heater, and the formation of the back coat layer is performed in the same process as the shaping of the surface material.

According to a second aspect of the present invention, there is provided a method for manufacturing a vehicle component, wherein a fabric having a high elongation such as a moquette or a soft weave is used as a surface material for the vehicle component, and the surface material is formed into a desired shape using a molding die.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, FIG. 1 shows a cloth material having a high elongation such as a moquette or a soft weave for a vehicle lining member such as a door lining, a roof panel, or an instrument panel. In the following, a step of applying a back coat material 2 such as an acrylic emulsion with a spray machine 30 after shaping the surface material 1 into a desired three-dimensional shape with a molding die 10 is shown.

The molding die 10 includes a base 11, clamps 12, 12,..., A drive mechanism such as a hydraulic cylinder 13, and a male die 14, and clamps 12, 12 around the edge of the surface material 1.
, The front covering material 1 can be stretched and supported on the base surface of the base 11 and the male mold 14 can be moved up and down by a drive mechanism such as a hydraulic cylinder 13.

With the use of the molding die 10, the surface of the flattened cover material 1 is turned downward so that the periphery of the front cover material 1 is clamped by clamps 12, 12. After being stretched and supported on the base surface, heated male mold 14
Is moved upward to press a mold surface having a desired three-dimensional surface from the surface side of the substrate fabric 1. Since the surface material 1 exhibits an elongation of about 8% on the material of the fabric, it can be easily formed into a three-dimensional shape corresponding to the mold surface by heating and pressing the male mold 14.

After shaping the surface material 1 into a three-dimensional shape, a spray machine 30 provided with a back coat material 2 such as an acrylic emulsion in the same process while holding the surface material 1 in the same male mold 14. To apply to the back side. As the back coat material 2, it is sufficient to apply about 70 g / m ² . After the application, as shown in FIG. 2, by replacing the sprayer 30 with the heater heater 40 and performing a drying treatment, a three-dimensionally shaped vehicle exterior member is obtained.

When the surface covering material for a vehicle component is manufactured as described above, since the fabric is formed into a three-dimensional shape as it is, it is possible to easily form a deep three-dimensional shape by making full use of the elongation rate of the fabric. . In addition, while holding the surface material 1 shaped in the three-dimensional shape with the male mold 14, the back coat material 2
Is applied and is dried and cured as a back coat layer, so that a three-dimensional shape having good precision and good shape preservability can be formed.

Subsequent to the manufacturing process of the facing material, the base material (not shown) for the vehicle mounting member is subjected to pressure bonding, so that the vehicle mounting member can be manufactured in the same process. In this press-bonding process, while holding the facing material 1 provided with the back coat layer in the male mold 14, a urethane-based adhesive is applied to the back surface side and dried, and the base material for the vehicle-mounted member is formed as a mating die, and It can be held by the female mold (not shown) equipped with the mold surface and bonded to the surface mounting material 1 by pressure bonding.

According to the manufacturing process of the vehicle component, since all processes can be performed in the same process as the shaping process of the surface material,
In addition to not only maintaining good moldability and preventing the occurrence of molding defects, it can also be reliably formed as a three-dimensional shape having good accuracy and good shape retention, and productivity and workability can be significantly improved.

In the above-described embodiment, the case has been described based on the case where the facing material 1 is formed using the male mold 14.
By applying suction molding or pressure molding using a female mold, the surface material 1 can be shaped into a predetermined shape.
