Patent JP-H07217195-A (JP)
Title: Synthetic resin panel for concrete form
Inventor: NISHIHARA MASAHARU
IPC: B32B27/20
Filed: 1994-02-07
Abstract: PURPOSE:To reduce cost and secure nailing and saw-cutting suitability by preparing both surface layers of thermoplastic resin having a specific thickness of a high bending elastic modulus and a core layer of thermoplastic resin having a specific melting point or mixed with a filler. CONSTITUTION:Thermoplastic resin is used as a core layer where the resin comprises a mixture of a plurality of different thermoplastic resins whose melting point in at least 30 deg.C or a mixture of an additional organic or inorganic filler. Even when the thermoplastic resin is molten with a friction heat during saw-cutting, there exists an isoluble residue at that temperature, which inhibits a drop in the performance of saw-cutting as a whole, thereby securing nailing suitability. Then, thermoplastic resin, which is 3mm thick and below and provided with a high bending modulus, is arranged to be on both the surface layers. In this case, a reprocessed product of laminated film waste or an additional mixture of wood flour or sander particles or added mixed polyorefin group resin is used for the core layer. More preferably, for both front layers thermoplastic resin reinforced with a reinforced material is employed.
