Abstract
The invention provides a water stop which comprises special self-adhesion modified asphalt, a surface-treated galvanized steel plate and an isolation material which are compounded together, wherein the self-adhesion modified asphalt is prepared by carrying out high-temperature shearing and high-speed dispersion on SBS or APP (Ammonium Polyphosphate), APAO (Amorphous Poly Alpha Olefin), SBR (Styrene Butadiene Rubber), a softener, tackifying resin, a filling material and an antiaging agent. The water stop provided by the invention is sequentially composed of the isolation material, the self-adhesion modified asphalt, the galvanized steel plate, the self-adhesion modified asphalt and the isolation material from top to bottom; a metal plate is utilized as a water stop reinforcing body, so that the strength of the water stop is improved, and the service life of the water stop is prolonged; the water stop is applicable to the construction joint and back strip of a reinforced concrete structure, and can be used for solving the problem that the waterproof effect of a project is influenced by rubber water stop damage caused by steel bars and sharp objects and overcoming the defects such as poor ageing property and the like of a rubber water stop; and the self-adhesion modified asphalt utilized as a coating is favorable in self-healing performance and higher in elongation at break and can form microcosmic full sticking together with concretes, thus the cohesive strength between the water stop and the concretes can be ensured, and water channeling and water seepage phenomena at the construction joint can be effectively prevented.
Description
Technical field
The present invention relates to a kind of waterstop, relate in particular to a kind of employing self-adhesion modified bitumen as coat, is the waterstop that strengthens body with the galvanized steel plain sheet.
Background technology
Expansion along with the modern city scale; City Building and bridge area do not subtract by increasing, and New-old concrete is constructed interval in work progress, and the face orientation continues; The continue processing method of face, New-old concrete is given birth to ripe batching and the control of vibrating all affects the waterproof quality of engineering.For guaranteeing construction quality, not only to improve the adhesion strength of New-old concrete, and will rationally handle constuction joint, prevent leaking, seeping water of building unit, thereby guarantee the application life of engineering construction.
The building engineering construction seam receives the influence of construction environment if adopt the high polymer waterproof material waterstop to be cast in the concrete, is prone to cause the destruction of performance; If adopt the asphaltic base pointing; Receive the influence of job practices, be prone to poorly sealed, if adopt the steel plate water-stopping band to be prone to get rusty; The post-processed trouble, so the selection of constuction joint sealing material is most important.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiency of above-mentioned prior art, provide a kind of do not receive the restriction of construction environment and form of construction work, with concrete binding excellent performance and the strong waterstop of suitable ability.
According to waterstop provided by the invention, comprise the special self-adhesion modified asphalt waterproof layer, surface-treated galvanized steel plain sheet and the isolated material that are combined with each other.
Also have following attached technical characterictic according to waterstop provided by the invention:
Said special self-adhesion modified bitumen is in pitch, to add in SBS or APP, APAO, SBR, softening agent, tackifying resin, filler, the age resister one or more.
Described special self-adhesion modified bitumen and cement mortar have higher bonding strength, have good self-healing property and hold viscosity.
Said galvanized steel plain sheet thickness is 1mm, and width is not less than 165mm, and length is not less than 2000mm.
Said surface-treated galvanized steel plain sheet is to adopt the sodium hydroxide solution of 5%NaOH to soak 30min, after finishing, immersion washes with clean water immediately comprehensively, and scrub, guarantee from viscous bitumen and galvanized steel plain sheet bonding good.
Said isolated material is twoly moulded single silicon release liners for what apply Organosilicon Release Agent.
Compared with prior art have following advantage according to a kind of waterstop provided by the invention: the present invention is made up of special self-adhesion modified bitumen, surface-treated galvanized steel plain sheet and isolated material; The surface receives cracking between the teeth broken of sharp-pointed foreign matter in the work progress; Can self-healing from viscous bitumen; And from viscous bitumen can and concrete between form the complete wetting on the microcosmic, produce intermolecular force, behind concrete curing; Show on the macroscopic view and be solid and reliable bonding, effectively stop liquid water and steam to infiltrate structure from constuction joint; Can expose for a long time, performance is unattenuated, and because galvanized steel plain sheet applies from viscous bitumen, can avoid carrying out in the follow-up work progress processing of rust removing work; Lap-joint for waterstop does not need sweat soldering, peels off isolated material and directly bonds, and gets final product permanent bonding together from viscous bitumen, avoids occurring in the work progress safety and the environmental issue that sweat soldering brings;
Description of drawings
Fig. 1 is a structural representation of the present invention.
Referring to Fig. 1, the embodiment of a kind of waterstop that provides in the present invention, 1 is the surface-treated galvanized steel plain sheet, 2 is the self-adhesion modified bitumen; 3 is isolated material, in use, at first peels off the isolated material of A part; Peel off the isolated material of B part during follow-up fluid concrete again, can expose easy construction for a long time; Can carry out self-adhesive more than-10 ℃, from viscous bitumen can with the permanent bonding of concrete, can avoid the constuction joint place phenomenon of leaking and seeping water to occur.
The specific embodiment
Following examples are used to explain the present invention, but are not used for limiting scope of the present invention.
