Description

Polymer composite guardrail section bar

Technical Field

The utility model relates to a building material field especially relates to a section bar for building guardrail.

Background

Chinese patent document publication No.: 101486289, announcement date: 7-22.2009 discloses a method for processing wood grains on an aluminum profile, which is characterized by solving the technical problem that the surface of an aluminum veneer or an aluminum profile cannot have wood grains in the prior art; the disadvantages are that: firstly, the production process is complex and the production efficiency is low; secondly, for irregular aluminum profiles, the positions with small gaps can not be uniformly transferred, and the decorative effect is poor; thirdly, the surface of the wood grain is easy to scratch and is not easy to repair.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a production simple process, production efficiency are high, applicable in irregular shape structure, the polymer composite guardrail section bar that the surface is stand wear and tear.

The technical scheme of the utility model is that: a polymer composite guardrail sectional material is formed by continuously and gradually rolling and cold-bending a composite material, and a closed hollow pipe is formed by closing a connecting interface; the composite material comprises a metal substrate and a film; one side of the film is printed with decorative patterns; the other side of the film is connected with the metal substrate.

The connector is provided with a stop section, a first connector and a second connector, the first connector and the second connector are mutually buckled and pressed, and the arc-shaped end of the second connector is tightly combined with the stop section.

The film is glued with the metal substrate into a whole through a gluing layer.

The film is directly extruded and jointed with the metal base material into a whole.

The metal substrate is a galvanized plate or an aluminum-plated zinc plate or an aluminum plate.

The film is a PVC film or a PET film.

The cementing layer is made of epoxy resin.

Compound guardrail section bar of polymer, through the shaping of the continuous roll cold-bending of combined material, form through the connector closure and seal hollow tubular product, the combined material includes metal substrate and film, one side of film is printed on the decorative pattern, the opposite side is connected with metal substrate. The composite material is directly formed by cold roll bending, the closed interface is used for forming a closed hollow pipe, the production process of the pipe is simple, the pipe is continuously produced by the cold roll bending forming machine, and the production efficiency is high. The connector sets up locking section, first interface and second interface, and the mutual lock of first interface and second interface compresses tightly, and the arc end and the locking section of second interface combine closely, and tubular product seals and need not the welding, and connector stable in structure has avoided because of tubular product welding seals the film damage that causes. The continuous rolling of combined material makes its surperficial polymer film evenly adhere to on the surface of tubular product, and decorative effect is good, has solved prior art because of section bar structure is irregular, the problem of the unable even rendition of the less department in clearance, the utility model discloses the difficult scratch in tubular product surface has the high resistant characteristics of scraping of hardness.

Fig. 2 is a schematic structural diagram of the composite material of the present invention.

Fig. 3 is a schematic view of the structure of the connection port of the present invention.

The notation in the figure is: the composite guardrail section bar 1 comprises a connecting opening 11, a first interface 111, a second interface 112, a stopping section 113, a composite material 2, a metal base material 21, a thin film 22 and a cementing layer 23.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and preferred embodiments, which are to be understood as illustrative of the present invention and not as limiting the scope of the invention.

As shown in fig. 1, 2 and 3, a polymer composite guardrail sectional material 1 is formed by continuously and gradually rolling and cold-bending a composite material 2, and is closed through a connecting port 11 to form a hollow pipe. The composite material 2 comprises a metal base material 21 and a film 22, wherein one side of the film 22 is printed with pattern patterns, and the other side of the film is connected with the metal base material 21. The connecting port 11 is provided with a stop section 113, a first interface 111 and a second interface 112, the first interface 111 and the second interface 112 are mutually buckled and pressed, and the arc-shaped end of the second interface 112 is abutted against the stop section 113. The composite material 2 is continuously rolled and cold-bent, and then is closed through the connecting port 11 to form a closed hollow pipe, the production process of the pipe is simple, the pipe is continuously produced through a rolling cold-bending forming machine, and the production efficiency is high. Interface 11 sets up stop section 113, first interface 111 and second interface 112, and the mutual lock of first interface 111 and second interface 112 compresses tightly, and the arc end of second interface 112 is inconsistent with stop section 113, and tubular product seals and need not the welding, and connecting portion stable in structure has avoided leading to the fact the film to damage because of tubular product welding seals. The continuous rolling makes the surface polymer film be evenly attached to the surface of the pipe, and the decoration effect is good.

As shown in fig. 2, the film 22 can be bonded to the metal substrate 21 by a bonding layer 23; or directly extruding and jointing the metal base material 21 into a whole through high temperature and high pressure.

Preferably, the metal substrate is a galvanized plate or an aluminized zinc plate or an aluminum plate.

Preferably, the film is a PVC film or a PET film, has the characteristics of high hardness and scratch resistance, and is not easy to scratch on the surface of the pipe.

Preferably, the cementing layer is epoxy resin, and the epoxy resin has excellent physical and mechanical properties, chemical corrosion resistance, heat resistance and bonding property.

The foregoing is only a preferred embodiment of the present invention and is not intended to limit the scope of the invention, any modifications, equivalents, improvements, etc. made within the spirit and principles of the invention should be included within the scope of the invention.
