Resin panel and method of producing the same

Abstract

[Object] Provided is a resin panel produced such that the positioning of a reinforcing material can be precisely done, rattling movement is prevented and distortion by molding shrinkage is not caused because the reinforcing materials are maintained in the foam. [Solving Means] A resin panel 1 is a hollow double-wall structure including a front wall 2, a back wall 3 and a peripheral wall 4 joining the front wall 2 and back wall 3 together. The peripheral wall 4 of the resin panel 1 has a welded part 7 on its entire periphery. Within a hollow part 5 is inner packed a foam 8 made of a thermoplastic resin that is formed in advance in the substantially the same shape as the shape of the space within the hollow part 5. The foam 8 is welded on the inner wall faces of the front wall 2 and back wall 3 of the resin panel 1. In the foam 8 are formed accommodation parts 10, 10 for accommodating reinforcing materials 9, 9. The reinforcing materials 9, 9 are lengthwise. The foam 8 intervenes between the ends of both of the reinforcing materials 9, 9 and the peripheral wall 4.

Description

technical field [0001] The present invention relates to a car interior decoration such as a cargo floor panel (a cover plate or a carrier of a car cargo room) or rear parcel shelves, or an interior decoration wall panel, door, etc. Resin-made boards used in shape-shaped construction products and the like and manufacturing methods thereof. Background technique [0002] In JP-A-10-80982, it is described as interior decorations such as luggage racks (parcel trays) used in vehicles such as automobiles and airplanes, or interior decorations such as decorative panels used in indoor walls, etc., that is, as A resin hollow molded product in which a material having an air layer such as a heat insulating material or a sound absorbing material, and a reinforcing material such as a steel pipe or a frame are arranged as an intermediate member of an interior decoration by blow molding of a sheet material. In addition, JP 2000-218682 A describes a resin hollow molded product in which a sh...

AI Technical Summary

Problems solved by technology

[0006] Therefore, the following problems have been pointed out: when a plurality of intermediate members are incorporated in a resin hollow molded product, the arrangement or positioning of the intermediate members between the molds is not easy, the molding accuracy is reduced, and the filling of the intermediate members cannot be obtained. state, looseness occurs, or in the case of an intermediate member that does not shrink, such as a metal reinforcing material, the deformation caused by the molding shrinkage of the resin hollow molded product becomes larger, etc.
