本発明は、車両用内装部材等の基板の成形方法に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of molding a substrate such as a vehicle interior member.
近年、車両等に装備される内装部材（例えばシート、イ
ンナパネル等）においては、車体重量の軽量化を計り、
かつ、乗員にソフト感を与え乗心地を向上させるため、
ポリプロピレンの樹脂で形成された基板に、ウレタン等
の詰物及び塩化ビニール等の表皮を接合させて形成する
か、あるいはそれらを一体に形成したものが用いられる
ようになつてきた。In recent years, interior components (e.g. seats, inner panels, etc.) installed in vehicles have been designed to reduce the weight of the vehicle.
In addition, in order to provide a soft feeling to the occupants and improve riding comfort,
A substrate made of polypropylene resin is joined with a filler such as urethane and a skin made of vinyl chloride, or a combination thereof has come to be used.
しかしながら基板がポリプロピレン樹脂製であり、そし

処理を施し、該接着面に凹凸を設けていた。このため作
業工程が増え、又、そのための設備が必要である等の問
題があつた。本発明は上記従来の問題点を解消するため
になされたものであつて、上記従来のようなプライマ処
理等を施すことなく、接着性を向上させることができる
基板の成形方法を提供することを目的とするものである
。However, since the substrate is made of polypropylene resin, and this polypropylene resin has extremely poor adhesive properties, after the substrate is molded, the adhesive surface of the filler such as urethane is treated with a primer or shotplast. , the adhesive surface was provided with irregularities. This resulted in problems such as an increase in the number of work steps and the need for equipment for the process. The present invention has been made in order to solve the above-mentioned conventional problems, and it is an object of the present invention to provide a method for molding a substrate that can improve adhesiveness without performing the above-mentioned conventional primer treatment. This is the purpose.
以下、本発明を図示せる実施例に随つて説明する。The present invention will be described below with reference to illustrative embodiments.
１０はポリプロピレン樹脂からなる基材１１を所定形状
に形成したものであり、表面にウレタン等の樹脂が接合
される車両用内装材等の基板である。10 is a base material 11 made of polypropylene resin formed into a predetermined shape, and is a substrate for a vehicle interior material or the like to which a resin such as urethane is bonded to the surface.
１２は基材１１を成形して基板１０を形成する型枠で上
型１２ａと下型１２ｂとからなり、基板１０のウレタン
１３等が接着される表面となる側の下型１２ｂ（もしく
は上型１２ａ）の圧接面には多数の小突起１４が刻設さ
れている。Reference numeral 12 denotes a mold for forming the substrate 10 by molding the base material 11, and it is composed of an upper mold 12a and a lower mold 12b. A large number of small protrusions 14 are engraved on the pressure contact surface of 12a).
今、上記基材１１を成形するには、先ず下型１２ｂの上
に接合部材となる紙１５を敷き、その上にオープンで加
熱軟化された基材１１を載置する。Now, in order to mold the base material 11, first, paper 15 serving as a bonding member is laid on the lower die 12b, and the base material 11 which has been heated and softened in an open state is placed on top of it.
然る後上型１２ａを下して加圧し成形する。これにより
基材１１に紙１５が圧着され、表面に凹凸１６が形成さ
れて表面積の大きい基板１０が形成される。尚、上記実
施例では基材１１の表面に紙１５を貼着するようにした
が、接合部材は該紙に限ることなく不織布もしくは金網
等でもよい。After that, the upper mold 12a is lowered and pressurized for molding. As a result, the paper 15 is pressure-bonded to the base material 11, and unevenness 16 is formed on the surface, thereby forming a substrate 10 with a large surface area. In the above embodiment, the paper 15 is attached to the surface of the base material 11, but the bonding member is not limited to this paper, and may be a nonwoven fabric, a wire mesh, or the like.

レタン、１７は塩化ビニール、ポリエチレン等の発泡体
からなる詰物、１８は塩ビシート等の表皮である。FIG. 3 shows a substrate 10 molded by the molding method of the present invention.
An example is shown in which interior material a is formed using resin, and is formed by integrally or adhesively bonding a resin to a substrate 10, 13 is urethane, 17 is a filling made of a foam such as vinyl chloride or polyethylene, and 18 is a filling made of a foam such as vinyl chloride or polyethylene. This is the skin of PVC sheets, etc.
以上述べたように本発明によれば、基材を成形して基板

の小突起を形成し、該小突起を形成した型と加熱軟化し
た基材との間に接合部材を布設して加圧成形したことに
より、基板の表面積が大きくなるように形成することが
でき、しかも、該表面に接合部材が圧着されるようにし
たので、接合面積を大きくすることができた。As described above, according to the present invention, a plurality of small protrusions are formed on the pressure contact surface forming the surface of the substrate of a mold for forming a substrate by molding a base material, and the mold in which the small protrusions are formed is By placing the bonding member between the heated and softened base material and performing pressure molding, the surface area of the substrate can be increased, and the bonding member is crimped onto the surface. Therefore, the bonding area could be increased.

に、該設備が不要になるため安価に提供することができ
る等の効果を有するものである。Therefore, a substrate with improved bonding properties in which the bonding member adheres to a resin such as urethane can be obtained. Therefore, it is possible to omit the work steps such as primer treatment that were conventionally performed, so it is possible to improve the productivity of the product, and the equipment can be provided at a low cost since the equipment is no longer required. It has the following effects:
