Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example one

Referring to fig. 1 to 3, in an embodiment of the present invention, a composite profile includes a profile body 1; section bar body 1 includes metal sheet 2 and macromolecular material layer 3, and macromolecular material layer 3 wraps up in the outside of metal sheet 2, is provided with a plurality of fusion through-holes 4 that are used for strengthening the 3 fastnesses of macromolecular material layer on the metal sheet 2, and at the concrete manufacturing process, the molten macromolecular material covers at the outside end of metal sheet 2, and partial macromolecular material fuses through fusing through-hole 4, the effectual stability that has increased the macromolecular material layer 3 of metal sheet 2 both sides.

Specifically, in the manufacturing process, the steel lining is coated and molded through an extrusion die by cold roll forming, under the specific temperature and pressure, taking PVC as an example, the melt pressure of an extruder is 380MPa, and the melt temperature is about 180 ℃, the high polymer materials are fused through hole positions, and the metal plate 2 is firmly locked.

Preferably, the fusion through hole 4 is a strip-shaped structure, which can effectively increase the connection strength of the polymer material layer 3.

Further, be located crisscross the setting of fusion through-hole 4 on the metal sheet 2 to make macromolecular material layer 3 have a plurality of stress points, and then further strengthen macromolecular material layer 3's joint strength.

Example two

The utility model discloses it is specific still to have proposed another kind of embodiment to perfect this application at the concrete implementation in-process, section bar body 1 adopts the setting of the two U type structures of symmetry, but wide application in high-grade steel construction villa, anticorrosive building materials, anticorrosive footboard, cable testing bridge, numerous fields such as chute, and application scope is wide.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
