Abstract
The utility model discloses a steel-plastic coextrusion wood plastic composite section bar including a section bar unit body, and being characterized in that the section bar unit body takes steel or aluminium as a carrier, and a wood plastic material layer is coated outside, the carrier is a thin wall support frame in a hollow structure, the wood plastic material layer is in an integrated structure and is formed through coextrusion together with the carrier. The section bar provided integrates the wood plastic section bar with the steel and aluminium materials, thereby increasing the physical rigidity and greatly enhancing the anti-compression capability of outdoor wood plastic composite section bars.
Description
Technical field
The utility model relates to a kind of steel-plastic coextrusion Wood-plastic composite section bar.
Background technique
At present, it is that employing PE, PP, PVC, waste or used plastics raw material and wood fibre filler (wood powder, bamboo powder, rice husk and various discarded crop stalks etc.) are main raw material that wood is moulded environment-friendly materials, mould by the customization different size, under High Temperature High Pressure, extrude the Wood-plastic profiles that comes in every shape through extrusion equipment.Wood-plastic profiles is the resource comprehensive recycling, and the environmental destruction of having avoided forest harvesting to bring on quality safety, because it does not contain formaldehyde, exempts from paint, nontoxic, more and more is taken seriously and approves; Simultaneously, wood-plastic products various shapes, attractive in appearance, the characteristics such as environmental protection low-carbon (LC) are favored by market.On product was used, the superiority such as the waterproof of wood-plastic products, mildew-resistant, Anti-moth-eating, anti-corruption made Wood-plastic profiles become the favorite of outdoor decoration material.
But existing Wood-plastic profiles is when install using, and owing to comprising plastic properties, intensity is lower, and bearing capacity is little is its drawback all the time, and how overcoming this drawback and being needs the technical barrier that solves in present Wood-plastic profiles production.
The model utility content
The drawback that exists in order to solve prior art, the utility model provide a kind of simple in structure, intensity is high, bearing capacity is large steel-plastic coextrusion Wood-plastic composite section bar.
The utility model technical solution problem adopts following scheme:
The steel-plastic coextrusion Wood-plastic composite section bar comprises the profile unit body, and its structural feature is, the profile unit body is take steel or aluminium as carrier, the outside Wood-plastic material layer that coats; Described carrier is the thin-walled support frame of hollow-core construction; Described Wood-plastic material layer is monolithic construction, itself and carrier coextrusion mold.
The utility model structural feature also is:
The upper surface of described Wood-plastic material layer is light face or frosting, and is provided with antiskid groove.
Described thin-walled support frame wall thickness is 0.5-2mm.
The material of described Wood-plastic material layer is that PP wood is moulded or PE wood is moulded.
Described thin-walled support frame is square tubular or circular pipe structure.
Be provided with in described thin-walled support frame and strengthen supporting.
Described support frame open at both ends or be provided with end socket.
Compared with prior art, the utlity model has advantage and effect is as follows:
The utility model Wood-plastic profiles and steel, aluminium material one have increased the physics rigidity, greatly strengthen outdoor Wood-plastic composite section bar anti-pressure ability; Wood is moulded and thin-walled support frame coextrusion mold, need not assembling, has greatly increased the convenience that the composite wood-plastic section bar uses; The Wood-plastic material layer of Wood-plastic profiles adopts PP or PE material; has the working life that delays wood plastic composite; strengthen weatherability, keep corrosion-resistant, anti-impact pressure, uvioresistant, anti-insect, exempt to paint the characteristics such as non-maintaining; have simultaneously energy-conserving and environment-protective, replace natural timber, the superior function of conservation of nature environment.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2, Fig. 3 are another two kinds of structural types of the utility model composite material.
Number in the figure: 1, thin-walled support frame, 2 Wood-plastic material layers, 3 grooves, 4 inner chambers, 5 are strengthened supporting.
Technical solutions of the utility model are described further by embodiment below in conjunction with accompanying drawing.
Embodiment
The steel-plastic coextrusion Wood-plastic composite section bar comprises the profile unit body, and the profile unit body is take steel or aluminium as carrier, the outside Wood-plastic material layer 2 that coats; As shown in Figure 1, carrier is the hollow thin-wall support frame 1 with inner chamber 4; Wood-plastic material layer 2 is monolithic construction, and itself and carrier are by the extrusion equipment coextrusion mold.
During enforcement; the thin-walled support frame is steel or aluminium (comprising the good materials of crushing resistance such as plastic-steel and aluminum alloy); as shown in Fig. 2,3; the required power of carrying of face shaping and application of moulding plate according to wood varies in size; skeleton can be selected square tube or the circular tube structure of hollow; can increase crossbeam, vertical beam etc. in it and strengthen supporting 5, namely form round, " mouth " the structures such as font, " day " font " order " font, sphere of movements for the elephants type, the skeleton wall thickness in profile unit is 0.5-2mm; Wood is moulded layer can select the materials such as PP wood is moulded, PE wood is moulded.Thin-walled support frame and Wood-plastic material are by the extrusion equipment coextrusion mold, be reprocessed into the profile unit of certain-length and width, when extruding, the upper surface of Wood-plastic material layer can be processed as light face or frosting, in order to strengthen skidproof effect, the surface can arrange antiskid groove 3; The anti-wood grain effect of polishing embossing also can be made to strengthen aesthetic appearance in its surface.The profile unit body is according to using needs, in the open at both ends of support frame, end socket can be set.
Claims (7)
1. the steel-plastic coextrusion Wood-plastic composite section bar, comprise the profile unit body, it is characterized in that, the profile unit body is take steel or aluminium as carrier, and appearance coats the Wood-plastic material layer; Described carrier is the thin-walled support frame of hollow-core construction; Described Wood-plastic material layer is monolithic construction, itself and carrier coextrusion mold.
2. steel-plastic coextrusion Wood-plastic composite section bar according to claim 1, is characterized in that, the upper surface of described Wood-plastic material layer is light face or frosting, and be provided with anti-slip tank.
