The utility model relates to a composite self-adhesion water stopper, wherein a main body takes the laminated structure and is sequentially provided with a self-adhesion layer, a fiber fabric enhancement layer, a thermoplastic elastomer core material layer, a fiber fabric enhancement layer and a self-adhesion layer. The composite self-adhesion water stopper has the advantages of light weight, aging resistance, good strength, convenient laying and the like.
Description
Technical field
The utility model relates to the waterstop that a kind of buildings waterproof is used, and being specially adapted to the concrete is three seam (hook, constuction joint, settlement joint) waterproof and the sealings located of railway, subway, water conservancy and civil building thing etc. of works.
Background technology
Because of reasons such as the contraction in the concrete for making process, distortion, concrete structure inevitably can produce a certain amount of crack.In order to satisfy the function of use requirement of concrete structure, can take crack Control Measures usually, deformation joint promptly is set, constuction joint and settlement joint default seams such as (comprising the ater-casting seam).In the prior art, can imbed rubber (adopting plastics on a small quantity) waterstop in these concrete default seams.On the one hand, rubber can produce elastic deformation under various loads, can satisfy works and play the fit sealing effect in the variable that allows; On the other hand, the waterstop two sides is provided with rib, can prolong or intercept the passage of water, thereby play resistance to deformation, the effect of sealing.It is in the waterproof sealing of railway, subway, water conservancy and civil building engineering of enclosed structure that rubber fastening band has been widely used in the concrete, but owing to include but not limited to the influence of following factors, adopt the default seam place of traditional rubber fastening band to occur leaking through regular meeting, engineering circle claims " ten seams nine leak ": one, owing to rubber, plastics etc. are non-caked with concrete, when rubber fastening band stressed or deformed by the influence of variation of ambient temperature after, rubber fastening band separates easily with concrete structure, thereby causes leaking; Two, because rubber fastening band weight is bigger than normal, rigidity is less than normal reason such as should not fix, and when concreting, rubber fastening band wanders off easily, thereby causes leaking; Three, because the cementing agent of rubber fastening band seam crossing comes off, can cause overlapping the slot place of waterstop and waterstop to peel off, thereby cause leaking; Four, owing to reasons such as restriction that is subjected to the material of rubber own and ageing of rubbers, rubber fastening band ruptures easily, leaks thereby cause.
Summary of the invention
The technical problem to be solved in the present invention provide a kind of in light weight, not easy fracture, be difficult for aging and NEW TYPE OF COMPOSITE self-adhesion water stop band easy for installation.
For solving the problems of the technologies described above, technical scheme provided by the invention is: the composite self-adhering waterstop, its main body has layer structure, and preface is provided with successively: self-adhesion glue-line, fabric enhancement layer, thermoplastic elastomer (TPE) core layer, fabric enhancement layer, self-adhesion glue-line.
Composite self-adhering waterstop with said structure is light by operating weight, the aging-resistant thermoplastic elastomer (TPE) is a core, and at core outside composite multi-layer fabric enhancement layer, the weight ratio tradition waterstop of composite self-adhering waterstop is alleviated about 35%, and strength ratio tradition waterstop exceeds about 40%.In addition, this kind waterstop is easy to launch to pave, and waterstop generation sideslip in the time of can preventing to lay also can effectively prevent the fracture of composite self-adhering waterstop, and prolong 2-3 doubly than traditional rubber fastening band or plastics waterstop application life.In addition, the self-adhesion glue-line all is set by both sides at the composite self-adhering waterstop, can make between composite self-adhering waterstop and concrete and the upper strata structure bonding easily, more convenient installation and laying.In addition, the overlap joint between waterstop and waterstop can be as a whole by being welded into.
Wherein, the material of thermoplastic elastomer (TPE) core layer can be the copolymer of TPO and EP rubbers and their dynamic vulcanization thing thereof, as TPO, TPE, TPR, SEBS, SBS etc.; Can also be TPUE such as TPU, or TPV TPV etc.
The self-adhesion glue-line can be colloidal silicic acid calcium creep self-adhesion glue-line or rubber pressure-sensitive adhesive layer, and they can react with concrete, forms " skin formula " bonding, thereby thoroughly solves because of leaking that peeling off between waterstop and concrete caused.
Scheme is that the main body of composite self-adhering waterstop forms flat wing plate preferably, is connected by telescopic hole between flat wing plate and flat wing plate.Telescopic hole can satisfy the needs of waterstop malformation by the effect of pressure.Flat wing plate structure can be avoided when concreting forming " dead angle ", and make vibrate more closely knit.
Scheme is that the edge part of composite self-adhering waterstop is provided with fixing hole preferably, with convenient waterstop is fixed on the reinforcing bar.
Scheme is that thermoplastic elastomer (TPE) core layer has sandwiched type structure preferably, its upper and lower two-layer thermoplastic elastomer (TPE) that is, and laminboard layer is a fabric.This kind structure can further improve the tensile strength of composite self-adhering waterstop, prolongs its application life.
Scheme is that the self-adhesive layer surface of composite self-adhering waterstop is provided with separation layer preferably.
