Problems solved by technology

[0013] Therefore, in the invention of the above-mentioned Patent Document 4, it is also conceivable that even if the resin binder of the fibrous base material is only locally melted so that the fibrous base material is closely bonded to the surface of the thermoplastic foam core layer, there may be a possibility that the fibrous base material may exist. Insufficient weld strength between base material and thermoplastic foam core layer

Abstract

Provided is a method for forming a resin molded product, the method being capable of improving the strength of fusion between a core material and resin sheets. A method for molding a resin molded product (100) by sandwiching and laminating a core material (102), which comprises a foamed body, between at least two molten resin sheets (101). The resin sheets (101) contain fibrous fillers. The core material (102) and the resin sheets (101) are fused together while the surfaces of the core material (102) are melted by the heat of the resin sheets (101), and the core material (102) and the resin sheets (101) are clamped together by dies to form the resin molded product (100).

Description

technical field [0001] The present invention relates to a resin molded article in which a resin sheet and a core material are laminated such that a core material made of a foam is sandwiched between at least two resin sheets. Background technique [0002] As a technical document filed prior to the present invention, there is disclosed a document related to a molding method of a resin molded product in which a resin sheet and a core material are laminated in such a manner that two resin sheets are sandwiched between the core material (for example, refer to Patent Document 1 : WO2009 / 157197, Patent Document 2: Japanese Patent Laid-Open No. 2011-51224, Patent Document 3: Japanese Patent Laid-Open No. 2011-51227). [0003] In the above-mentioned Patent Document 1 to Patent Document 3, two sheet-shaped parisons (corresponding to resin sheets) are supplied between the split molds, and the sheet-like parisons are shaped so as to follow the cavity of the split mold. shape. Next, t...
