Abstract
The utility model relates to a wood-plastic-aluminum composite door and window section bar, including outdoor aluminum alloy ex-trusions and indoor wood-plastic co-extrusion ex-trusions, indoor outer section bar forms through unsmooth platform interlock, and indoor wood-plastic co-extrusion ex-trusions is for wood-plastic to form or pour into after the shaping is moulded to wood through crowded technology with polyester alloy or polyester material and form, and its surface covers there is the special window membrane of ultraviolet resistance. The wood-plastic section is composed of wood fibers, a high polymer material and a special auxiliary agent, and the linear expansion coefficients of the wood-plastic section and the aluminum alloy section are very close to each other through repeated tests, so that the tensile damage of expansion with heat and contraction with cold to the section is well avoided, the overall strength of the section can be obviously improved through the polyester alloy or the polyester material, the deformation is effectively prevented, the heat insulation performance is improved, and the wood-plastic section has good practicability. The utility model has the advantages that: the aluminum alloy profile and the wood-plastic co-extrusion profile are compounded, the advantages of high strength of the aluminum alloy and good heat preservation of the wood-plastic profile are compatible, the strength, the sealing performance and the heat insulation performance of the integral profile and a window are further improved, the indoor decoration is improved, the cost is reduced, and the purposes of energy conservation and environmental protection are achieved.
Description
Technical Field
The utility model relates to a novel composite door and window section bar is a product that is used for making building door and window specially, including frame, fan, club and supporting section bar, annex.
Background
The existing wood-plastic section has good decoration and heat preservation performance, but has low strength; the aluminum alloy section has high strength, poor decoration and poor heat preservation performance; the aluminum-plastic co-extrusion section has large difference of linear expansion coefficients of two materials, large gap after expansion with heat and contraction with cold and single color.
Disclosure of Invention
The utility model aims at providing a wood is moulded aluminium composite door and window section bar, the performance advantage of full play aluminum alloy ex-trusions and wood plastic section bar reaches the thermal-insulated thermal insulation performance who improves whole door and window, increases indoor decorative and reduce cost.
The technical scheme of the utility model is that: a wood-plastic-aluminum composite door and window profile comprises an outdoor aluminum alloy profile and an indoor wood-plastic co-extrusion profile, wherein the indoor and outdoor profiles are formed by meshing concave-convex platforms, the indoor wood-plastic co-extrusion profile is formed by co-extrusion of wood plastic and polyester alloy or polyester materials or formed by injection after wood plastic forming, and the surface of the indoor wood-plastic co-extrusion profile is covered with an ultraviolet-resistant special window film.
The wood-plastic section is formed by extruding wood fibers, high polymer resin and special auxiliaries after high-temperature hot melting.
The polyester alloy or the polyester material is formed by a co-extrusion process with wood plastic, or formed by filling the polyester alloy or the polyester material after the wood plastic is formed, so that the integral strength of the section can be obviously improved, the deformation is effectively prevented, the heat insulation and preservation performance is improved, and the practicability is good.
The indoor surface of the wood-plastic co-extrusion section bar is coated with the anti-ultraviolet special window film, and the window film has colors, patterns and decorative patterns, so that the decoration is increased.
The occlusion mode of outdoor aluminum alloy and indoor wood plastic is that the occlusion surface of the aluminum alloy section is provided with an opening groove, and the occlusion surface of the wood plastic co-extrusion section is provided with a boss, so that the contact area is increased, and the combination is firm. Repeated tests show that: the linear expansion coefficients of the wood-plastic section and the aluminum alloy section are very close, so that a gap generated by expansion with heat and contraction with cold is well avoided.
The wood-plastic-aluminum composite door and window profile is characterized in that an aluminum alloy corner connector is placed in an outdoor aluminum alloy cavity, a nylon corner connector or an alloy corner connector is placed in an indoor wood-plastic cavity, and the wood-plastic composite door and window profile is connected at a combined angle and has high connection strength.
The wood-plastic-aluminum composite door and window profile is matched with an isobaric adhesive tape, and double sealing is realized, so that the air tightness is improved.
The utility model has the advantages that: the aluminum alloy profile and the wood-plastic co-extrusion profile are compounded, so that the high-strength advantage of the aluminum alloy and the good heat preservation property of the wood-plastic profile are compatible, the performance of the wood-plastic co-extrusion profile is further improved, the strength, the sealing property and the heat insulation property of the whole profile and a window are ensured, the indoor decoration is improved, the cost is reduced, and the purposes of energy conservation and environmental protection are achieved.
Drawings
Fig. 1 is a schematic view of a cross-sectional structure of the present invention.
Detailed Description
The section of the wood-plastic-aluminum composite door and window profile is shown in figure 1, wherein 1 is an aluminum alloy profile, 2 is a wood-plastic co-extrusion profile, 3 is a wood-plastic profile, 4 is a polyester alloy or a polyester material, 5 is an indoor ultraviolet-resistant special window film coated outside, and 6 is an isobaric adhesive tape. When the profile is manufactured, firstly, the polyester alloy or the polyester material and the wood-plastic are extruded together at high temperature, or the wood-plastic profile is extruded and molded firstly and then is filled with the polyester alloy or the polyester material, and after the finished product of the wood-plastic co-extruded profile is produced, the surface of the profile is coated with the anti-ultraviolet special window film. And then meshing the aluminum alloy section with the aluminum alloy section to obtain a finished product.
The wood-plastic section bar 3 is made by extruding wood fiber, high polymer resin and special auxiliary agent after high-temperature hot melting.
The utility model discloses it is compound with aluminium alloy ex-trusions with wood-plastic is crowded section bar altogether, the advantage of compatible aluminium alloy high strength and the good advantage of wood-plastic section bar heat insulating ability to wood-plastic is crowded section bar altogether's performance has obtained further promotion, and intensity, sealing performance, the thermal-insulated thermal insulation performance of whole section bar and window have all obtained the assurance, have increased indoor decorative and reduce the cost, have realized energy-concerving and environment-protective purpose.
