Description
Technical field:
The utility model relates to a kind of building weather strip, particularly relates to the compound building doors and windows curtain wall weather strip of extruding of a kind of soft or hard.
Background technology:
Existing building doors and windows curtain wall weather strip, especially the weather strip overwhelming majority of the dynamic contact position of building doors and windows is " 0 " font soft sealing strip, promptly the material of Cai Yonging all is homogenous material and single hardness, as soft PVC and thermosetting ethylene propylene diene rubber, this kind weather strip is easy deformation in coiling packing and storage process, be to go in assembling process by manually the bottom of weather strip being expressed to firmly in the groove in the section bar, section part applies glue bonding again, and in extrusion process, can cause the weather strip distortion, and adhesive strength is not high yet, simultaneously weather strip is subjected to the external force effect, pulls out from groove easily or breaks away from, and the weather strip bottom is difficult to cooperate tight with the groove of section bar, easily loosening, do not have the better seal effect, secondly, it is loaded down with trivial details that existing building doors and windows curtain wall weather strip is also deposited installation, waste time and energy.
In addition, the rigidity and the insufficient strength of the building doors and windows curtain wall weather strip of employing polyvinyl chloride are good, toughness is very poor, be assemblied in and often be subjected to ultraviolet irradiation and rain drop erosion in the building doors and windows curtain wall, time one is long to be easy to weathering, be full of cracks and to cause poor sealing performance, and, also contain halogen and may cause the composition of environment pollution with other.
Generally speaking, existing building doors and windows curtain wall weather strip have easy deformation and come off, assemble complicated, fixed position size instability and intensity difference, and non-environmental protection with can not cycling and reutilization etc. problem.
Summary of the invention:
The purpose of this utility model is to provide a kind of improved soft or hard the compound building doors and windows curtain wall weather strip of extruding, it not only can realize doors and windows sealing, waterproof, windproof, dustproof, sound insulation and noise reduction effect effectively, and, structure, make rationally, simultaneously Halogen, environmental protection, can cycling and reutilization.
Solution of the present utility model to achieve the above object is: the compound building doors and windows curtain wall weather strip of extruding of soft or hard of the present utility model comprises a weatherstrip body, described weatherstrip body is formed by hard skeleton and soft elastic packing part, described hard skeleton is the hard skeleton of high rigidity thermoplasticity ethylene propylene diene rubber, described soft elastic packing partly is the soft elastic packing part of soft thermoplasticity ethylene propylene diene rubber, describedly be inverse-T-shaped shape body for the hard skeleton of high rigidity thermoplasticity ethylene propylene diene rubber, described soft elastic packing upper end partly for soft thermoplasticity ethylene propylene diene rubber is the hollow body of semicircular in shape shape, the bottom is for being the body of falling the groove shapes, describedly is the hard skeleton of high rigidity thermoplasticity ethylene propylene diene rubber and partly is one by the extruder coextrusion is compound for the soft elastic packing of soft thermoplasticity ethylene propylene diene rubber.
Described soft elastic packing upper end partly for soft thermoplasticity ethylene propylene diene rubber is the hollow body of shape triangular in shape, and the bottom is for being the body of falling the groove shapes.
Described soft elastic packing part for soft thermoplasticity ethylene propylene diene rubber is that hollow body of rounded shape and bottom are formed by being the horizontal hollow body of oblong-shaped by the upper end, and described bottom is that the center of lower surface on the limit, lower end of the hollow body of oblong-shaped that is horizontal also is provided with a groove longitudinally.
Described hard skeleton is the hard skeleton of high rigidity thermoplasticity ethylene propylene diene rubber, described hard skeleton for high rigidity thermoplasticity ethylene propylene diene rubber is the strip shape body of soft thermoplasticity ethylene propylene diene rubber for also being distributed with mutually across a certain distance horizontal on body and the both sides end face in the form of sheets respectively, described be the soft elastic packing of soft thermoplasticity ethylene propylene diene rubber partly for the hollow body of rounded shape, what be distributed with mutually the hard skeleton of high rigidity thermoplasticity ethylene propylene diene rubber of body in the form of sheets of horizontal strip shape body for soft thermoplasticity ethylene propylene diene rubber across a certain distance and the hollow body of rounded shape on the end face of described both sides respectively is one by the extruder coextrusion is compound for the soft elastic packing part of soft thermoplasticity ethylene propylene diene rubber.
Described hard skeleton is the hard skeleton of modified poly ethylene or the hard skeleton of modified polypropene.
Because the utility model has improved the compound building doors and windows curtain wall weather strip of extruding of existing soft or hard, described weatherstrip body has adopted by being formed for the hard skeleton of high rigidity thermoplasticity ethylene propylene diene rubber with by the soft elastic packing part of soft thermoplasticity ethylene propylene diene rubber, and the soft elastic packing of the hard skeleton of the high rigidity thermoplasticity ethylene propylene diene rubber of described weatherstrip body and soft thermoplasticity ethylene propylene diene rubber partly to pass through the extruder coextrusion compound be one.
The compound hard skeleton of extruding building doors and windows curtain wall weather strip of soft or hard of the present utility model plays the location and the supporting role of building doors and windows curtain wall weather strip in door and window curtain wall, and easily assembling effect, and can be fixed on the plastic-aluminum section bar by card article, in the time of on the card article card, the card article end face directly withstands the soft elastic packing part of one deck of the upper end that is coated on hard skeleton, play the second road sealing function, hard skeleton is also owing to make the hard skeleton of high rigidity thermoplasticity ethylene propylene diene rubber or the hard skeleton of modified poly ethylene, or the hard skeleton of modified polypropene, and has certain rigid and intensity.
The compound soft elastic packing of extruding building doors and windows curtain wall weather strip of soft or hard of the present utility model partly plays the elastic packing effect, soft elastic packing partly is commonly used in the mobile contact site of dynamic seal (packing), when door and window is closed, soft elastic packing operative tip is subjected to certain pressure and is out of shape and is close to the door-window section bar edge, and weather strip was in compressed elastic packing state when door and window was closed, play extraordinary sealing, waterproof, windproof, dustproof, the sound insulation and noise reduction effect, when door and window was opened, the release of pressure elastic recovery of compressed soft elastic packing part was to original state.
Soft or hard of the present utility model is compound extrude building doors and windows curtain wall weather strip solved existing for single material and hardness building doors and windows curtain wall weather strip easy deformation and come off, assemble complexity, fixed position size instability and intensity difference, be difficult for gluing or sweat soldering global formation, and also remedied existing building door and window curtain wall weather strip, as the environmental protection of polyvinylchloride and thermosetting ethylene propylene diene rubber and can not cycling and reutilization etc. problem.
Soft or hard of the present utility model is compound extrude building doors and windows curtain wall weather strip Halogen, environmental protection, can cycling and reutilization, fixed position dimensional accuracy height, intensity are good, can the thermal weld global formation, realize the easily modularization weather strip of assembling.
