Description
Technical field
It the utility model is related to the waterproof technique of Construction of Civil Engineering seam, more particularly to a kind of self-adhering-type waterstop.
Background technology
Underground engineering sets construction joint because the needs of construction technology must stay, including vertical equity construction joint is vertical with ring applies
Work is stitched.With reference to《Technical code for water proof in underground engineering》And engineering practice, in setting in the middle part of the construction joint buried water stop effect compared with
It is good.Existing middle buried water stop mainly has steel plate water stopper and rubber fastening band, and the two is in engineering construction and water-stagnating effect side
Face difference is larger.Steel plate water stopper is easily installed, but water-stagnating effect and endurance quality slightly owe ideal；Rubber-like waterstop sealing is imitated
Fruit and durability are preferable, but not easy to install.The utility model waterstop can make up the defects of above two waterstop simultaneously, and simultaneous
The advantages of both tools.
The construction joint commonly used in existing underground engineering carries steel plate water stopper or galvanized steel plain sheet waterstop with sealing.But existing
Following point be present in real application：
Steel plate water stopper or galvanized steel plain sheet waterstop material are rigidly larger, are easy in place and installation in construction, but due to it
The desciccation crack of larger width is easily formed between cast-in-place concrete so as to cause percolating water, water-stagnating effect is not ideal.
Steel plate water stopper easily occurs electrochemical corrosion, causes steel plate to produce corrosion when contact band is corrosive underground water,
Serious time several years, which can become rusty, wears rotten, loses water-stagnating effect.Though galvanized steel plain sheet waterstop protects body in Zinc coat
Steel plate, but because field test means are limited, zinc coating thickness is difficult to detect, and if exist zinc-plated uneven or have plating leakage point, this
The meeting accelerated corrosion of body steel plate, can run counter to desire on the contrary.
Steel plate water stopper or galvanized steel plain sheet waterstop scene overlap joint need full weld, and welding quality is easily by manual operation factor shadow
Ring, and weld easy damaged galvanized steel plain sheet waterstop Zinc coat, overlap joint quality is unstable.
The construction joint commonly used in existing underground engineering carries rubber fastening band or rubber watertight strip with sealing.But existing
Following point be present in real application：
Rubber fastening band and rubber watertight strip are elastomeric material, flexible larger, its shape between cast-in-place concrete
Into desciccation crack it is smaller, ideally water-stagnating effect is more excellent；Yet with inconvenience peace in flexible material work progress
Dress, joint scene are difficult to heat cure docking processing, often form dislocation, distortion, lodging phenomenon, joint processing is not good at, so as to lead
Cause percolating water.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of self-adhering-type waterstop, to effectively improve waterstop peace
Fill efficiency of construction and water resistance.
Technical scheme is as follows used by the utility model solves its technical problem：
Self-adhering-type waterstop of the present utility model, including waterstop base material, the transverse ends of waterstop base material are sealing section,
It is characterized in that：The upper surface of the sealing section, lower surface coating hot-fusible pressure-sensitive adhesive form Waterproof glue line, covered outside Waterproof glue line with
Formation bonding separation layer.
The beneficial effects of the utility model are to effectively improve waterstop installation efficiency and water resistance, can with it is cast-in-place
Full viscous, blocking penetrating passage is formed between concrete；Reduce corrosivity underground water and waterstop contact area, improve waterstop
Durability；Sealing band body is the preferable material of rigidity, and in place, solution rubber fastening band and steel side rubber are easily installed in construction
The problem of misplacing, distort in glue waterstop installation process, lodging；It is easy to live overlap joint, is not required to welding or live heat cure docking,
Joint area barrier film, bonding only need to be torn；When the temperature of the surroundings is low, it can slightly toast and can glue using air-heater
Connect, overlap reliable in quality.
Brief description of the drawings
This specification includes following two width accompanying drawing：
Fig. 1 is the structural representation of the utility model self-adhering-type waterstop；
Fig. 2 is the structural representation of sealing section in the utility model self-adhering-type waterstop；
Component and corresponding mark are shown in figure：Base material 1, sealing section L, Waterproof glue line 2, separation layer 3.
Embodiment
Utility model is further illustrated with reference to the accompanying drawings and examples.
Reference picture 1, self-adhering-type waterstop of the present utility model, including waterstop base material 1, horizontal the two of waterstop base material 1
Hold as sealing section L.Reference picture 2, the upper surface of the sealing section L, lower surface coating hot-fusible pressure-sensitive adhesive form Waterproof glue line 2, prevented
Covered outside gelatine layer 2 and form cohesive separation layer 3 therewith.When waterstop is installed, separation layer 3, Waterproof glue line 2 and peace need to be only torn
The concrete structure bonding at position is filled, effectively improves waterstop installation efficiency.
The waterstop base material 1 is rubber substrate waterstop, plastic basis material waterstop, thermoplastic elastomer (TPE) base material sealing
Band, it is firm in rubber substrate waterstop, it is firm while plastic basis material waterstop or firm side thermoplastic elastomer (TPE) base material waterstop in it is any
It is a kind of.The separation layer 3 can use thermoplastic polymeric thin film, one side or two-sided painting silicon, it is preferred to use two-sided painting silicon thermoplasticity
Polymer thin film, there is excellent mechanical strength, and easily peeled off in work progress from the hot-fusible pressure-sensitive adhesive surface in sealing area,
It can keep using for a long time.
Self-adhering-type waterstop of the present utility model produces as follows：
1. selected waterstop base material 1；
2. waterstop base material 1 is preheated 5~10 minutes in 80~100 DEG C of drying box, hot-fusible pressure-sensitive adhesive is heated to
160~180 DEG C, be coated onto after its completely melting the sealing section L of waterstop base material 1 upper surface, formed on lower surface it is anti-
Gelatine layer 2；
3. treating that the surface temperature of Waterproof glue line 2 is reduced to 80 DEG C~room temperature, bonding is formed therewith in being covered outside Waterproof glue line 2
Separation layer 3.
The component of the preparing raw material of the hot-fusible pressure-sensitive adhesive by weight is：100 parts of polyisobutene, styrene-isoamyl two
3.0 parts of 70~100 parts of alkene-styrene, 110 parts of C5 Petropols, 3.0 parts of titanium dioxide or carbon black, 1.0 parts of antioxidant, light is steady
Determine 0.5 part of agent, 0.5 part of ultra-violet absorber.
The hot-fusible pressure-sensitive adhesive is prepared as follows：The preparing raw material of hot-fusible pressure-sensitive adhesive is added into kneader in batches
In, and be heated thawing and stir, speed of agitator is controlled at 100~150 revs/min；After each component completely melting,
Continue stirring 1.5~2 hours, and keep the temperature at 160~180 DEG C；Finally discharge stand-by.Hot melt pressure that is prepared and using
Quick glue with concrete peel strength, hold viscosity be much larger than existing hot-fusible pressure-sensitive adhesive, jail can be formed with young concrete structure
Adhere knot, it can be ensured that waterstop has excellent adhesive property and water resistance.
Some principles of the utility model self-adhering-type waterstop described above that simply explains through diagrams, are not intended to this reality
Shown in new be confined to and in described concrete structure and the scope of application, thus every corresponding modification for being possible to be utilized with
