Abstract

The utility model relates to a door and window sectional material, particularly a multi-layer composite door and window sectional material, which solves the problems of the prior composite door and window sectional material that a thickening layer is required to be covered on the periphery of a middle layer thereof, which brings high manufacturing cost, complicated mould structure, high productioncost, etc. The material comprises a reinforcing inner liner and a middle layer, wherein the surface of the middle layer comprises an indoor side surface and an outdoor side surface as visible surfaces, and a glass mounting surface and a fixing surface as concealed surfaces; and forming thickening layers are added to the visible surfaces which are located on the indoor and the outdoor side surfaces as well as outside the middle layer. The forming thickening layers adopt a secondary composite forming process which ensures the surface rigidity, smoothness and flatness, thereby solving the problems that the surface rigidity is poor, the dirt can be concealed easily and the forming is not good; and in addition, under the premise that the strength and appearance of the sectional material are not influenced, the forming thickening layers are only added to the visible surfaces of the door and window sectional material, so that the mould production is greatly simplified, and the production cost as well as manufacturing cost of the sectional material are reduced, thereby achieving certain popularization and use value.

Description

The MULTILAYER COMPOSITE door-window section bar

Technical field

The utility model relates to a kind of door-window section bar, is specially a kind of MULTILAYER COMPOSITE door-window section bar.

Background technology

Existing is liner with the steel pipe, the plastics-steel shapes for door and window of plastics externally-packed structure is compared traditional overall plastic or all-metal door-window section bar and is had the intensity height, advantages such as gross weight is light, its manufacture craft generally adopts steel-plastic coextrusion formula sclerderm foaming one-shot forming technique, but be subjected to the restriction of manufacturing process at present, forming this structure just must use foamed plastic to realize the sclerderm foam process, in the actual fabrication process, be subjected to all multifactor influences, the remarkable consequence of bringing is that the surface forms micro-pore structure easily, this defective causes the forms rough surface, hide dirt, breed bacteria easily; Cause the plastic layer uneven distribution even in operation easily, make the section bar distortion of moulding bigger, precision is relatively poor, die cavity is not just, difficulty is big during assembling window, and problem is many, owing to adopt sclerderm foaming one-shot forming technique, its case hardness is low, produces pit or breakage because of collision makes the surface easily in daily use.So practical application is not extensive.

This application people discloses a kind of three layers of novel composite door and window frame section bar in the patent No. is 200720138490.7 patent application, adopt sclerderm foaming one-shot forming technique and secondary combination process to make, originally mould by wood, compound again one deck thickening layer outside the intermediate layer that foamed plastic is made, thickening layer is made by hard PVC, engineering plastics, can effectively improve the mechanical property of section bar, reach instructions for use, and forms surface easy to clean.But in actual use, after this door-window section bar and door and window install, only indoor side and outdoor side are visible surface, all the other are as the glass installed surface, with the stationary plane of body of wall be concealed surface, there is not the problem that causes pit or breakage because of collision in these concealed surfaces in daily use, there is not the cleaning problem yet, can not influence the attractive in appearance of integral body, and above-mentioned three layers of composite door and window frame section bar all wrap up one deck thickening layer in the periphery in intermediate layer, caused unnecessary waste, increased the cost of production of this section bar, simultaneously when compound thickening layer, employed mould structure more complicated, cost of manufacture is higher, the processing technology instability is difficult to control.

Summary of the invention

The utility model all wraps up one deck thickening layer in order to solve above-mentioned three layers of composite door and window frame section bar in the periphery in intermediate layer, and problems such as cost of production is higher and mould structure is complicated, cost of manufacture is high, processing technology instability provide a kind of MULTILAYER COMPOSITE door-window section bar.

The utility model is to adopt following technical scheme to realize: the MULTILAYER COMPOSITE door-window section bar, comprise the reinforcement liner, be compounded in and strengthen the outer intermediate layer of liner, the intermediate layer periphery is provided with draw-in groove, interlayer surfaces is included as the indoor side and the outdoor side of visible surface and is the glass installed surface and the stationary plane of concealed surface, and innovative point of the present utility model is outside the intermediate layer and is positioned on the visible surface of indoor side and outdoor side to set up the moulding thickening layer.

Described moulding thickening layer is made by hard PVC or engineering plastics; Have heat insulation cavity on the described intermediate layer, its quantity can be determined according to actual needs, can further increase insulation, the soundproof effect in intermediate layer.

Adopt structure design of the present utility model, the moulding thickening layer has used the secondary composite molding technique, has guaranteed surperficial hardness, fineness, and planeness, thus it is poor to have solved case hardness, easily hides dirt, the problem that mouldability is bad; And under the prerequisite that does not influence section bar intensity and outward appearance, only on the visible surface of door-window section bar, set up the moulding thickening layer, simplified the making of mould greatly, reduced cost of manufacture, reduce the cost of production of section bar simultaneously, had certain popularization value and use value.

The specific embodiment

The MULTILAYER COMPOSITE door-window section bar, as Fig. 1,2, shown in 3, comprise and strengthen liner 1, be compounded in the intermediate layer of strengthening outside the liner 12, the same with existing three layers of composite door and window frame section bar, strengthen liner and generally use metal inner lining, frp lining, carbon fiber liner etc., strengthen filling heat insulating wall 11 in the liner cavity, the material that use in the intermediate layer can be moulded (WPC) as wood, perhaps foamed plastic, have heat preservation and soundproof and mechanics effect preferably, have heat insulation cavity 10 on the described intermediate layer, the intermediate layer evagination forms protuberance 9, also be provided with heat insulation cavity 10 in the protuberance, intermediate layer 2 peripheries are provided with draw-in groove 3,2 surfaces, intermediate layer are included as the indoor side 4 and the outdoor side 5 of visible surface and are the glass installed surface 6 of concealed surface and stationary plane 7, stationary plane be generally with the stationary plane of body of wall or with the stationary plane of hardware, intermediate layer 2 is outer and be positioned on the visible surface of indoor side 4 and outdoor side 5 and adopt secondary composite molding technique composite molding thickening layer 8, and moulding thickening layer 8 is made by hard PVC or engineering plastics.
