Abstract

A reinforced cellular plank filled with polyurethane composite and a method for fabricating such a plank belong to the technical field of cellular plank and aim to provide a high-strength, thermal-insulating, soundproof and reinforced cellular plank filled with polyurethane composite. The technical proposal includes two panels, a cellular core and the filling material of polyurethane composite; the cellular core is positioned between the two panels, filled with the filling material of polyurethane composite, and agglutinated with the panels by the polyurethane composite composed of polyurethane and polyester in the weight ratio of (1-3) : (1-3). The fabricating method includes preparing the polyurethane composite, applying the composite to the panels, combining the cellular core with the panels, compression and heating process. The invention can be applied to fabricate furniture and building materials and produces such beneficial effects as high strength, good damp-proof, thermal-insulating and soundproof performance, light weight, saving lumber, environment-friendliness, as well as low manufacture and transportation costs.

Description
