Abstract

The utility model discloses a composite structural profile, and the composite structural profile comprises wood and plastic composite materials, or an inner core made of the wood and plastic composite materials, and a reinforced layer, wherein the reinforced layer is coated on the external surface of the inner core in whole or in half and the thickness of the reinforced layer is 0.4 to 2.5MM; the inner core made of the wood and plastic composite materials is a hollow or solid core material, and the reinforced layer is made of high-performance resin materials or improved composite materials. The core material of the utility model uses ordinary and cheap wood and plastic composite materials or wood and plastic Foam materials, and the external surface of the core material is coat with the reinforced layer which has good physical and mechanical properties; the structure not only enables the composite structural profile to have a longer service life and to bear larger load, but also the price of all the materials is not largely increased; the application occasions are wide, and the utility model can satisfy the consumption needs of markets.

Description

The composite construction section bar

Technical field

The utility model relates to a kind of floor section bar, particularly a kind of composite construction section bar.

Background technology

The floor that Wood-plastic foam material or wood plastic composite are made has light weight, cheap characteristics, is used widely, but h is in the limitation of its material itself, this floor in case long-time or in outdoor application, intensity can't satisfy bigger load, application life is shorter.

The utility model content

Technical problem to be solved in the utility model is, a kind of composite construction section bar is provided, and its external surface has one deck enhancement Layer, can make this section bar bear bigger load.

For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of composite construction section bar, described composite construction section bar comprises inner core and the enhancement Layer that wood plastic composite or Wood-plastic foam material are made, enhancement Layer wraps entirely or partly is coated on interior core outer surface, and the thickness of described enhancement Layer is 0.4～2.5mm.

Wherein, described inner core is hollow or real core core; Described enhancement Layer is high performance resin material or modified composite material.

The beneficial effect that the utility model can reach is: core of the present utility model adopts common, cheap wood plastic composite or Wood-plastic foam material, and coat at the core external surface and to have good physical mechanical performance enhancement Layer, this structure does not singly make this composite construction section bar have long application life, can bear bigger load by structure, and the integral material price can be not unprecedented soaring, the application scenario is extensive, satisfies the market comsupton demand.

Description of drawings

Fig. 1, Fig. 2 the utility model embodiment composite construction section bar generalized section.

The specific embodiment

Extrude the inner core 1,3 that solid wood plastic composite materials (as Fig. 1) or hollow Wood-plastic foam material (as Fig. 2) are made this utility model composite construction section bar through thermoplastic molding's double screw extruder plasticizing, enhancement Layer 2 is extruded whole outer surface or the local external surface that is bonded in inner core through another extruder, promptly get the utility model composite construction section bar, the THICKNESS CONTROL of the enhancement Layer that is coated is at 0.4～2.5mm.

Claims

1, a kind of composite construction section bar is characterized in that: described composite construction section bar comprises inner core and the enhancement Layer that wood plastic composite or Wood-plastic foam material are made, and enhancement Layer wraps or partly be coated on interior core outer surface entirely, and the thickness of described enhancement Layer is 0.4～2.5mm.

2, a kind of composite construction section bar according to claim 1 is characterized in that: described inner core is hollow or real core core.

3, a kind of composite construction section bar according to claim 1, it is characterized in that: described enhancement Layer is high performance resin material or modified composite material.
