上に熱可塑性表面化粧シートを一体化させて複合成形体
を製造する方法に関するものであり、その製品は自動車
内装部品、家具、ドア表面材等の凹凸化粧材として使用
に供されるものである。[Detailed description of the invention] This relates to a method of manufacturing a composite molded product by integrating a thermoplastic surface decorative sheet thereon, and the product is used as a textured decorative material for automobile interior parts, furniture, door surface materials, etc. It is served to
一般に厚手の熱可塑性基体用シート上に表面化粧用シー
トを一体的に積層して成形体を得る方法としては以下の
方法がとられている。Generally, the following method is used to obtain a molded article by integrally laminating a surface decorative sheet on a thick thermoplastic substrate sheet.
■あらかじめ基体用シートと表面化粧用シートをラミネ
ートしておいて同時に真空もしくは圧空レス成形する方
法。■A method in which the base sheet and surface decorative sheet are laminated in advance and then vacuum or pressureless molding is performed at the same time.
■基体用シートを真空もしくは圧空成形しておいて、該
成形品に穴あけ加工を施し、しかるのらに該成形品を真
空成形型として表面化粧用シートを真空成形して一体化
させる方法。(2) A method in which a base sheet is vacuum or pressure-formed, the molded product is perforated, and then the molded product is used as a vacuum mold to vacuum-form a surface decorative sheet to be integrated.
上記の３方法がとられているが、■の方法においては、
基体用シートと表面化粧用シートの間に多少共空気が介
在する場合には，フクレ、接着不良等の原因となるので
極めてラミネートが困難なばかりでなく、基体用シート
が厚い場合には真空成形時の予備加熱にかなりの熱量を
必要とするので、表面化粧用シートが溶融したり、「ヤ
ケ」を生じたりし、極めて困難性を有するものである。The above three methods are used, but in method ■,
If there is some air between the base sheet and the surface decorative sheet, it may cause blisters, poor adhesion, etc., making lamination extremely difficult, and if the base sheet is thick, vacuum forming may be difficult. Since a considerable amount of heat is required for preheating, the surface decorative sheet may melt or "stain", which is extremely difficult.
又、表面化粧用シートの加熱成形条件が基体用シ−トの
加熱条件より低い場合には表面化粧用シートが溶融ｌ−
て成形不可能となる。Furthermore, if the heating conditions for the surface decorative sheet are lower than the heating conditions for the base sheet, the surface decorative sheet will be melted.
It becomes impossible to mold.
また、■の方法においては雄雌型を必要とする為、真空
成形に比して極めて全型代が高価となるばかりでなく、
特別のプレス機を必要とするので装置が極めて大規模と
なり、家具、ドア材等の小ロット品への対応が全く不可
能である。In addition, method (■) requires male and female molds, which not only makes the total mold cost extremely expensive compared to vacuum forming, but also
Since a special press machine is required, the equipment becomes extremely large-scale, and it is completely impossible to handle small-lot products such as furniture and door materials.
■の方法においては、基材用シートをあらかじめ真空成

面化粧用シート表面が真空成形型の型面に接していない
為に成形体の形状が月くなる等の欠点を有する。In method (2), the base material sheet is vacuum formed in advance and then holes are punched, and the surface decorative sheet is also vacuum formed, which not only complicates the process, but also makes the surface decorative sheet surface vacuum-formed. Since it does not touch the mold surface of the mold, it has disadvantages such as the shape of the molded object becoming moon-shaped.

The present invention provides a method for manufacturing a composite molded body by laminating the above.

成形体を得ることができる。Next, the present invention will be explained with reference to the drawings. First, as shown in FIG. The sheet (2) is placed so that its decorative surface faces the mold surface.Then, as shown in FIGS. 2 and 3, a base sheet that can be preheated and molded is placed on top of the sheet. (3) is placed with its adhesive coated side (3a) facing down.
The surface decorative sheet (2) has air permeability and is heated and plasticized by the heat of the base sheet (3), so it is integrally molded according to the base sheet, and when taken out from the mold after cooling. , as shown in Figure 4, the base sheet (3)
A composite molded article can be obtained in which the surface decorative sheet (2) and the decorative surface sheet (2) are integrally laminated.
次に本発明の構成要因について詳細に説明する。Next, the constituent factors of the present invention will be explained in detail.

500 per 100cc using the measurement method of 5-P-e 177
It is necessary to have an air permeability of 2 seconds or more (measured in seconds of 500 seconds or less). This is because if the time is longer than 500 seconds, the time required for integral molding will be too much, and the base sheet will cool down before being completely molded, resulting in poor molding.
次に本発明に使用される基体用シートについて説明する
。Next, the base sheet used in the present invention will be explained.

However, for use in automobile interiors, furniture, and door surface materials, certain Shape retention is required, and in general, individual sheets of ABS resin sheets with a thickness of 19 or more, polystyrene resin sheets, polypropylene resin sheets, polyethylene resin sheets, etc., or individual sheets of these It is possible to use a resin-based material mixed with inorganic materials, pulp, wood flour, etc. in the form of a sheet.

組み合せにおいても伺ら支障なく成形可能となる。Since the present invention has the above-mentioned configuration, it is possible to extremely efficiently manufacture a concave-convex belly assembly by one-time vacuum or pressure forming using an inexpensive and simple vacuum or pressure forming mold and vacuum forming machine or pressure forming machine. In addition, since the decorative surface of the surface decorative sheet is not heated, the surface decorative sheet will not melt or "stain" due to heating, and the surface decorative sheet will not be embossed. Even when the embossed pattern is embossed, the embossed pattern is less likely to return and the embossed pattern can be faithfully reproduced. Furthermore, since the surface of the surface decorative sheet is in direct contact with the mold, it is possible to obtain a composite molded product with good reproducibility of the shape of the mold. Furthermore, it is possible to form a combination of a surface decorative sheet and a base sheet with different preheating conditions without any problem, which is completely impossible with the method (2) of pre-laminating and vacuum or pressure forming.
