Abstract

PURPOSE:To obtain an interior decorative member without sags or breaking of shapes by a method in which a base member, a cushion member and the skin members of different kinds are laminated, and while causing this laminate to adhere under pressure by the molds with projected portions, high frequency voltage is applied to the specified parts of said skin members. CONSTITUTION:The surface of the cushion member 2 made of polyurethane foam, etc. is coated with an adhesive 3, and this cushion member 2 is placed on the base member 1 such as a hard board. Next, the skin members 4, 4' made of a synthetic resin leater and a cloth and placed on said cushion member such that a part of said resin is mutually polymerized. Thus, a laminate 10 is formed. Then, the laminate 10 is caused to adhere under pressure by the molds 20, 20' having the projected portions 21 for fixing a pattern and the conductive parts at the portions 21' of said projected portions 21, whereby each layer is caused to adhere along its whole surface. Further, high frequency voltage is applied to said conductive parts, and they are welded, thereby obtaining the interior decorative member.

The present invention relates to a method and apparatus for manufacturing an interior material in which a seed skin material is simultaneously applied and a three-dimensional pattern is added to the surface thereof.

樹脂レザーの表皮を配することが行われている。In recent years, in car door trims, cloth #skin has been applied to areas that are often touched, such as armrests and door opening/closing handles, to improve the feel, and other areas such as the upper edge and the foot area are coated with cloth #skin. Synthetic resin leather is placed on areas that are easily soiled.

ところで、このようなドアトリムは乗尚の安全と居住性

構造とされている。Incidentally, such door trims generally have a structure in which a cushioning material is placed under the skin in order to improve riding safety and comfort.

他方、このようなドアトリムを製造する方法としては種

がある。On the other hand, there are various methods of manufacturing such a door trim, but the following is one of the most commonly used manufacturing methods.

れている。Step 5: Place a cushioning material such as a polyurethane foam sheet on the base material, place the synthetic resin leather on top of it, and weld the periphery and designated areas of the surface to the base material using a high-frequency welder to form the synthetic resin leather. After making the outer skin part, I added cloth I! ! It is manufactured by a simple process in which a cloth covering material or cushioning material is sewn or glued onto a predetermined position on the synthetic resin leather to produce a cloth skin part.

。However, in this manufacturing method, the above-mentioned process, two steps t.
- In addition, if the cushioning material is to be covered with cloth, a separate process is required. Furthermore, because the aforementioned high-frequency welder causes only local adhesion, wrinkles tend to occur radially around the adhered area, and because each layer is not bonded over the entire surface, the skin material tends to sag. It has the disadvantage of easily causing problems such as. Furthermore, since the fixed surface area for applying the pattern is generally small, the fixed part often comes off during use, causing the overall shape to collapse.

ある。Therefore, in view of the above, the present invention seeks to provide a novel method for manufacturing interior materials, particularly a method for manufacturing interior materials having different types of skin materials, and an apparatus for manufacturing the same. A cushioning material coated with adhesive is placed on the base material, and a synthetic resin leather and a cloth upholstery are placed on top of it so that some of them overlap each other, and this laminate is shaped into the desired shape. The layers are crimped with a mold having a conductive part on at least a part thereof, each layer is bonded over the entire surface, and a high frequency voltage is applied to the conductive part to weld the overlapping part of the skin material. The present invention relates to a method for manufacturing an interior material in which a three-dimensional pattern is provided at a predetermined position on the surface of the interior material, and an apparatus for manufacturing an interior material in which a part of a mold having a protrusion for providing the pattern is made of a conductor.

〜２０１１の厚さが好ましい。2 is a cushioning material made of reed, polyurethane foam, or other foamed plastic sheet having an open cell structure. An adhesive 6 is applied to the surface of the cushion material 2, and a portion of the adhesive 6 is impregnated into the surface layer of the cushion material. This is because the cushioning material has an open-cell structure. A preferred example of the adhesive 6 is a reactive adhesive that is a prepolymer of polyol and isocyanate and contains an excess of incyanate. This adhesive reacts and hardens extremely easily with water or other active hydrogen. The thickness of this cushioning material 2 is determined by the cushioning properties required of the interior material, but is usually 5.
A thickness of ~2011 is preferred.

。Next, this laminate 10 is molded into a mold 20 having a desired protrusion.
Press it with 20 yen. The mold is a laminate 10 as shown in FIG.
4. A protrusion or protrusion (hereinafter referred to as a protrusion) 21 is provided on the surface of one of the molds 20 (the upper mold in the embodiment) that comes into contact with the surface material 4.4, and the laminate 10 is pressed against the surface of the mold 20. When this is done, the structure is such that unevenness is imparted to the skin material side. A portion 21' of the protrusion 21 is made of an aluminum conductor and is connected to a high frequency generator 30.

他方の型２０１には、前記の導電体からなる突部２１１

非導電体で構成されている。The parts other than the conductive part of the mold 20 and 201 are made of a non-conductor, such as glass fiber reinforced plastic or ceramic, and the small protrusions 21 that form a shallow pattern on the surface of the laminate are also made of a non-conductor. .

２３は、型２０．２０Ｉを加熱するためのヒーター又は

２を付設された所望の立体形状に保持することとなる。Note that, as a matter of course, the cushioning material is pressure-bonded to the base material. In addition, at this time, since the mold is heated by a heater or the like, reaction hardening of the adhesive B is promoted, and since the hardening adhesive 6 is impregnated on the surface of the cushioning material 2, the curing of the adhesive 3 The skin material 4.41 and the cushion material 2 are held in the desired three-dimensional shape.

即ち凹凸模様が付されることとなる。他方、！２０１も
加温されているため、突部２１を有する型からの加熱と

なる。In other words, an uneven pattern is provided. On the other hand! Since the cushioning material 201 is also heated, the cushioning material 2 is entirely bonded to the base material 1 in combination with the heating from the mold having the protrusion 21 .

前記においては、合成樹脂シートの表皮材が外方に位置

In addition, since the overlapping parts of different types of skin materials are welded using high frequency almost at the same time as the pressure bonding of the laminate, door trims, etc., which require 14 types of skin materials such as cloth skins and synthetic resin sheets, can be produced in the - process. It has the advantage that it can be manufactured, and the manufactured door trim etc. can be provided without sagging or deformation of the skin material due to peeling etc. due to the entire surface bonding of each component.

ある。On the other hand, the mold has a conductive protrusion at a desired position, and the other protrusions and crotches are made of ceramic or non-conductive material made of fiber-reinforced plastic, so it provides good insulation between adjacent conductors. It has the advantages of being able to hold the mold, reducing the weight of dust, and making molds easier to manufacture.
