LFT-D IN-MOLD FILM COATING PROCESS FOR BUILDING FORMWORK

摘要

The present invention relates to the technical field of building formwork manufacturing, and specifically discloses an LFT-D in-mold film coating process for a building formwork. The process comprises: using polypropylene and glass fibers as raw materials, and adding same to an extrusion device so as to extrude a mixed material; introducing a mirror sheet into an oven for heating and softening; installing a mold in a frame-type pressing machine, feeding the mixed material in a mold cavity, and then covering the softened mirror sheet above the mixed material in the mold cavity; and driving the mold to be closed by means of the frame-type pressing machine, and performing compression molding. The present invention has simple steps of film coating process and good molding effects. A mirror-covered building framework is formed by using polypropylene and glass fibers as raw materials, extruding the mixed material by means of an LFT-D process, and then the mirror material, after softened, entering the pressing machine together with the mixed material, and performing compression molding. The mirror-coated building framework has the advantages of being wear-resistant, prolonging the service life and being easy to demold, improves the construction efficiency, and reduces the construction cost.
