により両者間が剥離することがあり、耐久性に乏しい。However, instrument pads made of vacuum-formed ABS sheets have no flexibility in shape, feel hard to the touch, have poor chemical and heat resistance, and have decorative stitch patterns on their surfaces. It is difficult to obtain other free textured patterns. In addition, when the ABS sheet is exposed to extreme temperatures, the skin and the foam may peel apart due to the difference in thermal expansion coefficient between the two, resulting in poor durability.

から概略構成されている。Figure 2 shows the mold used for this molding.
This includes a lower mold, that is, a female mold 10, which constitutes the outer shape of the molded product, and an upper mold, which constitutes the back side of the cylindrical product, which is removably connected to one side of the lower mold 10 via a hinge 11. The mold is generally composed of a male mold 12 and a fastener 13.13 located at the open/closed end of the mold 10.12 and clamping between the two when the mold is clamped.
そして上記下型１０には凹凸状の型面１０ａが形成され

て凹凸状の型面１２ａが形成され、両型１０．１２ｆｌ
ｆｌを型締めした状態で両型面間には所要の空隙（キャ
ビティ）が形成されているようになっている。The lower mold 10 has an uneven mold surface 10a, and the upper mold 12 has an uneven mold surface 12a corresponding to the mold surface 10a.
A required gap (cavity) is formed between both mold surfaces when fl is clamped.
そして上記下型１０の型面１０ａの内面には更にこれと
相似形状をなすシリコン型１４が着脱自在に嵌合されて

更に成形品の離型性を良好ならしめる目的で設けられた
ものである。This silicone mold 14 is used to process grains and stitch patterns on the outer surface of the molded product during the molding process described later.
This is provided for the purpose of making it possible to forcibly remove undercuts if there are any undercuts on the die cutting, and also for the purpose of improving the mold release properties of the molded product.
以上の如き構成された成形型を用いた成形順序について
説明すると、
まず上記シリコン型１４の内面にスプレー装置１５等に
よってウレタン硬化性樹脂液が塗布され、この塗布され
た樹脂液は硬化して高分子ウレタンエラストマ表皮を形
成する。To explain the molding sequence using the mold configured as above, first, a urethane curable resin liquid is applied to the inner surface of the silicone mold 14 using a spray device 15 or the like, and this applied resin liquid hardens and becomes high. Forms a molecular urethane elastomer skin.

すなわち硬化剤とプレポリマーとの混合後の貯蔵時間が
短いが、優れた物性が得られる。The material of this urethane curable resin liquid has a molecular weight of 500.
It is a mixture of a prepolymer of ~4000 adipate polyester, a diisocyanate, and a curing agent. A polyester having a molecular weight of 500 to 4,000 is best. Further, the diisocyanate for providing the prepolymer has an incyanate □...:I group bonded to an aliphatic carbon atom, and when these are blended, a product with excellent weather resistance and light resistance can be obtained. Next, an amine is used as a curing agent for this prepolymer, and by diluting the fatty film-grade diamine with a ketone solvent and using the amine, the amine forms a Schiff group, It is possible to create a skin with excellent physical properties, and when the above prepolymer is diluted with a solvent and Schiff base is added and spray applied, the solvent dissipates and the equilibrium of Schiff base shifts towards forming diamines. It rapidly starts reacting with the prepolymer to obtain a polymeric urethane elastomer, and due to this reaction mechanism, the pot life, that is, the storage time after mixing the curing agent and the prepolymer is short, but excellent physical properties can be obtained. .
なお、このポットライフの短い点は表皮材料をスプレー

り解決される。The short pot life is that when spraying the skin material, the main agent and curing agent are introduced from separate tanks with hoses 17 and 18 up to just before the spray device f15.
At this stage, the two are instantaneously mixed and stirred using a static mixer 19 to solve the problem.
次に第２．第３図に示すようにスプレー塗布後上型１２
の型面１２ａ上に上述の成形芯板１をセットしておく。Next is the second one. As shown in Figure 3, the upper mold 12 after spray coating
The above-mentioned molding core plate 1 is set on the mold surface 12a.

ス成形される。As mentioned above, this core board 1 is made of wood chips containing lignin polysaccharides, such as wood flour obtained by grinding hardboard waste to 100 mesh, and polypropy9lene with a particle size of 80 to 150 microns. 50 parts by weight = 50 parts by weight The composite resin molding material is made by kneading the mixture in a section and molding the mixture into a board shape using two-wheel wide extrusion. When this is heated and extruded at 170 to 190°C, polypropylene is produced by removing impurities and lignin contained in wood flour. Together with polysaccharides, it is plasticized and evenly coats and adheres to the wood fibers that are a component of wood flour, creating a press-molded board that is a resource-saving material that combines the advantages of both wood and synthetic resin and compensates for their disadvantages. As described above, this composite resin plate is press-molded into a shape that matches the shape of the instrument pad.
なお、第５図（ａ）、（ｂ）に示すものは上記成形芯板

インサートされることになる。Furthermore, what is shown in FIGS. 5(a) and 5(b) shows a cross section of the above-mentioned molded core plate 1, and metal fittings 20 and 21 such as iron plates or iron pipes are inserted inside the above-mentioned core plate 1. It is formed. During press molding of the core plate 1, the metal fittings 20 are attached to the mold surface of the press mold in the required shape.
．． 21 is installed, and if a semi-molten composite resin plate is press-molded in this state, metal fittings 20 and 21 as shown in the figure will be inserted.
この場合においては芯板１の強度が大となり、しかも部

場合でも安全性が高いという利点を有する。In this case, the strength of the core plate 1 is increased, and because the metal fittings 20 and 21 are partially inserted, the amount of haze is reduced compared to the conventional press-formed core plate composed of a single steel plate. Moreover, since the metal fittings 20 and 21 are embedded in the composite resin by inserts, there is an advantage that safety is high even if the core plate is exposed.
このようにセツティング作業が終わったならば第３図に

着する。After the setting work is completed, a predetermined amount of foaming urethane resin liquid is injected into the inner surface of the silicone mold 14 using the urethane injector 16 as shown in FIG. 12 is engaged with the lower mold and clamps 13 and 13 are engaged to clamp the mold, the foaming resin liquid foams between the core plate 1 and the elastomer skin H2 formed by the above process, and the foaming 113, the skin layer 2 made of the urethane elastomer and the core plate 1 are bonded to each other.

されることになる。After the foaming hardens, the upper mold 12 is separated from the lower mold 10, and then the molded product is transferred together with the silicone mold 14 to the lower mold 10.
By removing the mold from the mold surface 10a and then peeling off the silicone mold 14, an automobile instrument pad with all parts integrated as shown in FIG. 1 is obtained. Note that the silicon mold 14 is set on the lower mold 10 again after its mold surface is cleaned.

いる。In addition, to describe the characteristics of the elastomer skin layer, the elastomer skin layer has excellent gloss and feel, good low temperature properties, and wear resistance compared to conventional ABS resin sheets and PVC Pustisol skins. In addition to being excellent, it has low deformation due to weather resistance and heat shock, and has excellent chemical resistance and impact resistance.Furthermore, compared to PVC plastisol, there is no clouding due to the absence of volatile components such as plasticizers. It has a large degree of freedom in design due to its molding characteristics, and also has features such as freedom in coloring.
