するようにしている。Therefore, in the past, when manufacturing a molded object, fibers (short fibers or long fibers) were mixed into the molded object, or reinforcement was made using a metal net (wire mesh), a synthetic fiber net, or a plate material such as an iron plate. Or, they are reinforced by laminating different materials.

また、本発明で接着材料とは、合成樹脂系。Further, in the present invention, the adhesive material is a synthetic resin type.

ｃｐｓを超えた粘度の高い場合には、塗布等の作業性に
劣り実用的でなく、好ましくないからである。If the viscosity is low (less than 1000 Cps), it may flow out with the furnace liquid during molding, penetrate into the inorganic mixed material, or flow out with the flow of raw materials when the mixed material is input. This is because adhesive strength is not exhibited, which is not preferable. Also, 200.000
This is because when the viscosity is high, exceeding cps, the workability of coating etc. is poor and it is not practical and is not preferred.

投入して加圧するようにすればよい。In order to laminate the reinforcing member and the kneaded material via this adhesive material, the reinforcing member is coated with an adhesive material to form an adhesive layer, and then placed in a mold, and then the kneaded material or green plate is introduced. All you have to do is pressurize it.
上記補強部材に接着材料を塗布して接着層を形成する方
法としては、ロール法、スプレー法、含浸法等の公知の
処理手段を挙げることができる。As a method for forming an adhesive layer by applying an adhesive material to the reinforcing member, known processing methods such as a roll method, a spray method, and an impregnation method can be used.
また、接着層を形成する工程は加圧成形工程と同時に行

材料の粘度は１０００ｃｐｓ以下であっても良好な接着
状態を得ることも可能である。In addition, the process of forming the adhesive layer may be performed at the same time as the pressure molding process, and the adhesive layer may be applied to the reinforcing member each time, or the reinforcing member may be separately prepared with a roughened adhesive layer applied in a separate process.
Any method may be used, such as a method of supplying the material to the pressure molding process each time. In the latter case, although the number of processing steps increases, it is possible to obtain a good adhesive state even if the viscosity of the adhesive material is 1000 cps or less.
上記混練物と接着材料を介して積層される補強部材とし

率の向上が得られたり、反対側の成形体の表面に平滑性
を付与したり、あるい（よプレス型に模様を施しておけ
ば、成形体の表面に模様を施すことも可能となる。The reinforcing member to be laminated with the above-mentioned kneaded material via the adhesive material is a flat plate material such as a galvanized iron plate or a steel plate, or a net-like material. Even if the material is molded, water can be easily removed from the kneaded material during molding, improving molding efficiency. For example, it becomes possible to apply a pattern to the surface of the molded body.

されず好ましくないからである。The hardness of the adhesive layer after the pressure-molded adhesive material is cured is measured using a rubber hardness meter (JISA type ■, manufactured by Chiklok Co., Ltd.), and is suitably 20° or more. This is because the hardness must be sufficient to propagate the stress applied to the plate material of the crosstalk to the reinforcing member, and if it is too soft (less than 20°), the inorganic hardened material and the reinforcing member This is because peeling occurs due to shear stress between the layers (adhesive layer) and the reinforcing effect is not exhibited, which is not preferable.
