door and window frame made of cement extrusion with wrapping sheet and its door and windows

摘要

The present invention relates to a surface sheet lapping forming apparatus and a window frame of a window frame of cement material extrusion molding to wrap a synthetic resin film to produce a variety of patterns on the surface of the window frame extruded with cement material.;When the window frame is made of cement and cured at high temperature and high pressure after molding, it has become a product having excellent characteristics such as weather resistance and impact resistance having the same strength as rock, but unlike wood, it does not give a unique pattern. In order to improve such disadvantages, paints, which are common coating materials, are coated on the surface. As the paint is a simple painting, when the surface is peeled off for various reasons, the cement gray inside is exposed and it is not aesthetically good.;The present invention is continuously extruded using a general extrusion molding apparatus, but after the curing treatment at a high temperature and high pressure to maintain the molten state of the adhesive, the hot-curable adhesive is continuously applied to the bottom surface of the sheet and then the vertical horizontal in the lapping press (A) By using the parallel pressing roller and the corner pressing roller installed on the sheet, the sheet of synthetic resin was treated by adhesive treatment, which made it possible to manufacture window frames of various patterns.
