Description
Technical field
The present invention relates to waterproof roll technical field, one exposes the wet paving of macromolecule waterproof roll specifically.
Background technology
Early in the twentieth century, Waterproof Building Materials Overseas is mainly taking malthoid as main, and asphalt paper is substituted by glass malthoid gradually.Along with chemical industry particularly rubber industry had great development, development and production have gone out much resin and the rubber that is applicable to architectural waterproof material, make the investigative technique of architectural waterproof material obtain developing rapidly, the use of modified bituminous pitch coiled material and macromolecule coiled material is increasingly extensive.Common SBS, APP, EVA, EPDM membrane, self-adhesive coiled material heat ageing are poor, grow storage period, every physical and mechanical property index can decline, after irradiated by solar ultraviolet, downward trend is just more obvious, just have a greatly reduced quality with cement mortar or rear pouring concrete effect, even occur the situation that cannot bond.Cause thus the generation of channeling water phenomenon.In order to solve leakage-proof problem, in the nineties in 20th century, China has initiated self-adhesive coiled material, has proposed wet application, and coiled material and cement mortar or plain cement are realized full sticky, has well solved full gluing and the channeling water phenomenon that causes of material and structure.Obtain develop rapidly from the nineties in 20th century to the wet paving coiled material of self-adhesion class so far.Also the huge part of self-adhesion class now wet paving coiled material is all the wet paving of the self-adhesion class coiled material taking modified pitch as main body.The modified bituminous pitch coiled material of self-adhesion class, due to itself, all can not be used for exposing now.
Therefore, design from material self structure for overcoming the deficiency of above-mentioned technology, change sizing compound formula, make it can finely meet the requirement of storage life, stand, after heat ageing and ultraviolet ray irradiation, to keep good physical performance index, improved coiled material storage cycle, can also ensure that this coiled material well exposes wet waterproof roll, just the inventor's problem to be solved of spreading of macromolecule with the one of the bonding of cement mortar.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide one and expose the wet paving of macromolecule waterproof roll, it is simple in structure, easy to use, from material self structure, change sizing compound formula, make its requirement that can finely meet the storage life, stand after heat ageing and ultraviolet ray irradiation, keep good physical performance index, improve coiled material storage cycle, can also ensure this coiled material well and the bonding of cement mortar, had extraordinary practical value.
The technical solution adopted for the present invention to solve the technical problems is: one exposes the wet paving of macromolecule waterproof roll, comprise limit film, expose PVC layer, Macromolecular self-adhesive membrane, barrier film, it is characterized in that: described waterproof roll bottom is for exposing PVC layer, expose PVC layer top for Macromolecular self-adhesive membrane, Macromolecular self-adhesive membrane top is barrier film, and barrier film edge is connected with limit film.
The invention has the beneficial effects as follows:
1, high density polyethylene (HDPE) (HDPE) sheet material that material of main part of the present invention is used is as the body layer of this coiled material, on body layer, cover one deck hot-fusible high-molecular glue, hot-fusible high-molecular glue is non-asphaltic base and does not contain any solvent and plasticizer, adhesive property is extremely strong, tack, to hold viscosity all fine, determine that PVC can be for exposing, can meet the construction bond effect of coiled material in different basic units.
2, common asphaltic base self-adhesive coiled material is heated, ultraviolet, weather, malformation impact change larger, because weatherability and the stretch-proof performance of its material of main part itself are poor, the material of main part that the wet paving of macromolecule waterproof roll is selected is high density polyethylene (HDPE) sheet material, stretch-proof performance is good, hot, ultraviolet relatively little on its impact, the detection performance of material of main part is far away higher than the wet paving of GB/T23457-2009 P class index request.
3, the present invention exposes the hot-fusible high-molecular glue that the self-adhesion sizing material of the wet paving of macromolecule waterproof roll selection is non-asphaltic base, temperature to environment, storage time, heat ageing, ultraviolet radiation-sensitive are more much smaller than common asphaltic base self-adhesive, have greatly improved the storage time of coiled material in warehouse and building site.Improved the tack of coiled material and held viscosity, it is elongated and weaken that adhesion strength can be not in time.
4, basal plane requires lowly, and the construction of this coiled material can be rated as the highest waterproof material of the construction free degree, can, directly in moist basal plane construction, therefore, can not be subject to weather effect all-weather construction, and when rainy season construction, advantage is more obvious the duration.
5, reliable in quality, construction are convenient.Coiled material is from heavy and light, is easy to hang be laid on side wall facade and tunnel just serves as a contrast, and overlap joint is reliable, and construction quality is easy to ensure.Under the impact of practice of construction site environment factor, coiled material can have effective adhesive with concrete structure, forms the waterproof system of compound+fusion, fully recovers and brings into play the function of concrete structure from waterproof, reduces seepage probability.Waterproof effect is secure, and individual layer uses can meet one-level waterproof guard standard-required.
6, the reduction of erection time, low to basal plane conditional request, basal plane moisture content without impact, is not subject to weather effect on waterproofer.Conventional waterproof way relatively, structure is simplified, very obvious to the optimization of duration of a project, as: the construction of screed-coat, separation layer, protective layer and curing time omit, and have greatly shortened total duration of engineering.
7, system is simple, and cost is low, and material construction basic unit is substantially smooth, without screed-coat, when basement bottom board construction, can also cancel the structures such as protective layer, has reduced system cost, also reduces earthwork excavated volume simultaneously.Control for building invisible cost is also very obvious, as: low percolation ratio reduces maintenance cost, and accelerating construction progress reduces financial expenses.
8, bonding is reliable, easy access, and coiled material can be realized bonding with concrete main body structure, can effectively avoid the generation of " channeling water ".Even if coiled material part wrecks, also can water be limited to very among a small circle in, improved the reliability of watertight composition, even if seepage, because breakdown point and issuable breakthrough are in same position, is overhauled extremely easy.
9, safety and environmental protection, without primary coat and work with torches, avoids occurring dangerous matter sources, when having eliminated potential safety hazard, also economizes on resources.
10, hot strength is high more a lot of than common wet paving P class coiled material, and anti-pierceability, nail bar the physical index such as are torn and exceeded much than common coiled material.
11, the present invention exposes the indispensable extremely strong adhesive property of the wet paving of macromolecule waterproof roll, high with cement mortar adhesion strength.
12, the present invention exposes the wet paving of macromolecule waterproof roll heat ageing, ultraviolet ageing, good weatherability, can well resist the destruction that environment brings.
