Abstract
The utility model provides a kind of compound sealing rod for prefabricated components seam, including colloid A, colloid B and sawtooth seam, colloid A, colloid B are formed by sawtooth seam brushing adhesive cementation, and colloid A material is butyl rubber, and colloid B material is polyurethane material.Butyl rubber can play the water swellable effect in chance sea, and expansion multiplying power is adjustable, positive effect, practical；Polyurethane material can play a part of water-swellable, add the tight ness rating of sealing rod and construction of structures, so as to improve waterproof, sealing performance.
Description
Technical field
It the utility model is related to waterproof technique field, more particularly to a kind of compound sealing for prefabricated components seam
Bar.
Background technology
Sealing rod is formed by the inorganic water uptake expansion material of macromolecule and compounding rubber, is that work is constructed in various hypogees
The material of anti-leak-stopping is stitched in the building concrete engineering constructions such as journey, hydraulic engineering, traffic tunnel engineering, power plant cooling tower, municipal plumbing
Material, is currently that hydro-expansive rubber confirms its advantage water-swellable through practical application in recent years, with water sealing, prevents suitable for underground
Hydraulic Projects, concrete capillary are stitched, in construction joint.
But for coastal area and underground water containing mineral matter and the more serious environment containing salt but lose its expansion it is excellent
Point, experiment prove the sealing rod immersion of above standard in the seawater, and almost expansion multiplying power is zero.Therefore, a kind of energy of research is needed badly
Meet waterproof, the sealing rod of anti-seawater simultaneously.
Utility model content
In order to overcome the difficulty of coastal cities area prefabricated components seam waterproof, the utility model provides a kind of while full
The sealing rod of sufficient waterproof, anti-seawater.
The utility model uses following technical scheme：
A kind of compound sealing rod for prefabricated components seam, including colloid A, colloid B and sawtooth seam, the colloid
A, colloid B is formed by sawtooth seam brushing adhesive cementation, and colloid A material is butyl rubber, and colloid B material is poly- ammonia
Ester material.
Preferably, the material of the colloid A is butyl rubber, plays the water swellable effect in chance sea.
Preferably, the material of the colloid B is polyurethane material, plays a part of water-swellable.
The beneficial effects of the utility model are：It is more serious containing mineral matter and containing salt for coastal area and underground water
Environment but loses the advantages of its expansion, and experiment proves the sealing rod immersion of above standard in the seawater, and almost expansion multiplying power is zero.
Butyl rubber can play the water swellable effect in chance sea, and expansion multiplying power is adjustable, positive effect, practical；Polyurethane material energy
Play a part of water-swellable, add the tight ness rating of sealing rod and construction of structures, so as to improve waterproof, sealing performance.Cause
No matter this, run into water or seawater, can all produce expansion, plays waterproof, the effect of sealing.
Brief description of the drawings
Fig. 1 structural representations of the present utility model.
Reference
1 colloid A, 2 colloid B, 3 sawtooth seams.
Embodiment
The utility model is specifically described below in conjunction with the accompanying drawings：
A kind of compound sealing rod for prefabricated components seam, it is made up of colloid A1, colloid B2 and sawtooth seam 3.Institute
Colloid A1, colloid B2 is stated to form by the brushing adhesive cementation of sawtooth seam 3.Colloid A1 material is butyl rubber, colloid B2
Material be polyurethane material.
Butyl rubber can play the water swellable effect in chance sea, and expansion multiplying power is adjustable, positive effect, practical；Poly- ammonia
Ester material can play a part of water-swellable, add the tight ness rating of sealing rod and construction of structures, so as to improve waterproof, sealing
Performance.Therefore, water or seawater no matter are run into, can all produce expansion, plays waterproof, the effect of sealing.
