摘要:
A multilayer article such as a door trim board is fabricated by the steps of extruding melted resin layers (13m), (12m) and (11m) respectively forming a soft skin material (13), a foamed soft intermediate layer (12) and a base member (11) in the form of a multilayer resin sheet from a die-head (40) of an extruding machine, supply the extruded multilayer resin sheet to a molding machine in such a manner that the resin layer for the skin material is placed on a lower molding die of the molding machine and molding the resin layers in the form of the multilayer article. The resin layer for the skin material consists of thermoplastic elastomer, the resin layer for the intermediate layer consists of ethylenic copolymer copolymerized with ethylene and at least radical copolymerizable acid anhydride, and the resin layer for the base member consists of olefinic resin. The thermoplastic elastomer for the skin material is prepared in the form of olefinic thermoplastic elastomer and/or styrenic thermoplastic elastomer The melting flow rate of the thermoplastic elastomer is determined to be 0.1-200 g/10 min at 230.degree. C. under load of 2.16, and the shore A hardness of the elastomer is determined to be in a range of 50-96.
摘要:
The invention provides a laminated article such as a door trim board capable of maintaining a bonding effect for a long period of time by integrally forming a base member and a skin member without forming the skin member in the shape of a sheet and without using an adhesive, and a manufacturing method of the laminated article by which reduction in the quantity of materials to be used and simplification of manufacturing steps are achieved. A porous base member (11) molded in the shape of a door trim board and a molten resin (12melt) supplied on the surface of the porous base member are pressed between a pair of molds (31, 32) so that the molten resin (12melt) is impregnated into the porous base member at least at the front surface thereof and hardened to form a skin member (12) on the porous base member (11). In the door trim board thus obtained, the resin forming the skin member (12) and the porous base member (11) are integrated by an anchor effect of resin with a reliable strength thereof retained.
摘要:
A molded article includes a laminated wood-based fibrous web molded into a desired shape by a compression molding operation. The laminated wood-based fibrous web includes a wood-based fibrous web base and a synthetic fiber scrim laminated to the web base, the web base being formed of a fiber composition mainly constituted of wood pulp, synthetic fibers and binder, the scrim being impregnated with a synthetic resin.
