Description
Technical field
The present invention relates to a kind of building sealing strip, more particularly to a kind of wear-resisting building sealing strip of line sandwiched type, the door and window curtain wall for big facade long profiles.Belong to building doors and windows curtain wall auxiliary equipment technical field.
Background technology
Building doors and windows sealing strip is flexible（Retractility）, longitudinal direction（Along cross-wise direction）Elasticity be the reason for it can play sealing function.And sealing strip is in transverse direction（Along its length）It is same flexible, adhesive tape with section bar（Aluminium alloy, plastic-steel or Wood-door window）Stretching just occurs during quick assembling, but the stretching of this part can not persistently be kept, creep factor is deducted in use, sealing strip can little by little restore over time, so that sealing strip physical length shortens, caused result is that door and window corner gap occurs and leak, and this phenomenon is particularly susceptible when being used on the door and window curtain wall of big facade long profiles and gone wrong.Therefore it is desirable that flexible in the longitudinal direction of sealing strip, and it is smaller even without but the fact is not so in transversal stretching.In order to longitudinally there is bigger elasticity, it will usually sizing material hardness is done it is softer, but therewith into this than, the transversal stretching of sealing strip also can be bigger；Existing sealing strip is made of gum material, therefore small to the grip of counterpart, flexible poor during bending operation, it is impossible to meet the needs of client.
Existing sealing strip surface does not have wear-resistant coating, therefore after long-time use, its surface is easily worn, and influences sealing effectiveness.
The content of the invention
It is an object of the invention to overcome above-mentioned deficiency, there is provided one kind fills a kind of wear-resisting building sealing strip of line sandwiched type.
The object of the present invention is achieved like this：
A kind of wear-resisting building sealing strip of line sandwiched type, is characterized in：The wear-resisting building sealing strip of a kind of line sandwiched type includes left segmental arc,Right segmental arc,Crosspiece and single,The upper end of the left segmental arc is connected with the top of right segmental arc,The lower end of the left segmental arc and the left part of crosspiece connect,The left end of crosspiece stretches out the tie point with left segmental arc,Form an extension,The lower end of right segmental arc and the right-hand member of crosspiece connect,The single is embedded in crosspiece along its length,Single uses co-extrusion mode one-shot forming with sealing strip,The left segmental arc,Right segmental arc surrounds a hollow structure with crosspiece,Multiple internal tooths are provided with the inwall of the hollow structure,The bottom of the crosspiece is provided with trapezoidal buckle,The sealing strip is embedded in the insertion body for adopting the pectination being made of resin,The insertion body includes body and is arranged on the teeth portion on body both sides,Sealing strip surface is coated with wear-resistant coating,The wear-resistant coating includes fluoropolymer,Polymer adhesive and inorganic filler film hardeners,The weight of fluoropolymer and polymer adhesive ratio is 0.5 ~ 2.0:1, the weight ratio of packing thin film curing agent and fluoropolymer is 1.4:1, wherein thin filled film curing agent includes the ceramic particle that average grain diameter is at least 14 microns, ceramic particle is with least 1200 Knoop hardness, the aspect ratio no more than 2.5, at least three ceramic particles on the cross section of every 1 centimetre of wear-resistant coating.
Compared with prior art, the beneficial effects of the invention are as follows：
A kind of wear-resisting building sealing strip of line sandwiched type of the present invention, left segmental arc, right segmental arc and crosspiece surround a hollow structure, not only reduce the dosage of sealing strip, while the compression ratio of sealing strip is greatly improved；Multiple internal tooths are provided with hollow structure inwall, when sealing strip is compressed, internal tooth can increase the frictional force of sealing strip and part so that sealing strip fixation；Single is embedded in crosspiece along its length, because the inhibition of intrinsic fiber line causes the transversal stretching very little of sealing strip；The bottom of crosspiece is provided with trapezoidal buckle, and it is fixed and positioned that buckle is easy to staff to carry out；Sealing strip is embedded in an insertion body for adopting the dressing being made of resin, therefore grip of the sealing strip to counterpart can be improved, while sealing strip has good flexibility during bending operation, sealing strip surface is coated with wear-resistant coating, its abrasion is prevented, ensure that sealing effectiveness.
