The easily torn edge film and a surface film of the self-adhesive waterproof roll to form a one body, the edge portion of the surface film is provided with an impression line, the edge film is formed on the surface film at the outer side of the impression line, and the extension direction of the impression line is same to the tearing direction of the edge film. The easily torn edge film can simplify the film laminating technology of the self-adhesive waterproof roll and reduce the manufacturing and construction cost.
Description
Technical field
The present invention relates to a kind of auxiliary material of waterproof roll, be specifically related to a kind of easy torn edges film for adhesive waterproof coil, belong to laminar product technical field.
Background technology
Adhesive waterproof coil is resin, pitch is base-material, and upper surface is coated with polyethylene film, aluminium foil, and lower surface, coated with the adhesive waterproof coil from sticky separation layer, wherein selects the silicon oil membrane of peelable usually from sticky separation layer.Because it has extremely strong self-adhesive performance and self-healing property, the site operation very adapting to high and low temperature environment and can not get angry, and be also applicable to waterproof, the antiseptic project of pipeline.Possess following advantage:
Without binding agent when 1, constructing, need not heat bake, tear off and just can be bonded in basic unit securely from sticky separation layer, construct convenient, the duration be short.
2, the performance of elasticity, percentage elongation and rubber is close, can to the distortion of basic unit and cracking self adaptation.
3, excellent to the bonding force of basic unit, and cohesive force is greater than the shearing force that adhesive surface ruptures outward, edge overlap joint is tight reliable.
4, can the less puncture of self-heal damaged, after puncture or hard object embed, coiled material and insert combine together, the water resistance of still maintenance.
5, not only rely on the pitch base material waterproof of main body, its polyethylene film overlying strata also has waterproof and structural strengthening effect, and its waterproof has double insurance.
6, construction safety, the use of the flames of anger and bonding agent, environmentally friendly, on-the-spot 5S is up to standard.
7, corrosion-resistant, acidproof, alkaline-resisting, resistance to chemical attack, is suitable for the commercial Application such as cesspool, storage tank.
Current adhesive waterproof coil extensively should in fields such as the roofing of work China Democratic National Construction Association, the underground space and municipal works, cistern, swimming pool, subway tunnel waterproof.Apply limited timber structure, metal structure roof waterproof at other coiled materials, and oil depot, chemical plant, textile mills, grain depot waterproofing work, adhesive waterproof coil also obtains with its specific advantage and promotes the use of.Visible adhesive waterproof coil possesses wide market prospects.
Through retrieval, Chinese patent literature CN104354432A disclose a kind of adopt pre-installed and inverted adhered to construct Macromolecular self-adhesive membrane waterproof roll and production method, the structure of this Macromolecular self-adhesive membrane waterproof roll as shown in Figure 1, comprise polymeric main watertight composition 1-1, self-adhesive glue layer 1-2, adherent layer 1-3 and PET film overlap joint boundary layer 1-4, its self-adhesive glue layer 1-2 can with rear pouring concrete generation chemical reaction and be cured as one, achieve the full sticky of main water barrier and structural concrete, the problem that effectively can solve underground waterproof seepage channeling water or cause main water barrier to lose efficacy because of settlement of foundation.In order to carry out the overlap joint of following film on adjacent web when constructing, its overlying strata comprises separate adherent layer 1-3 and PET film overlap joint boundary layer 1-4, need at diverse location overlay film at twice during manufacture, especially adherent layer 1-3 needs to cover centre, leave a blank one section of coated with PET film overlap joint boundary layer 1-4 again on both sides, manufacturing process is numerous and diverse, and material variety is many.In automated production in enormous quantities, existing product structure adds the complexity of system and the difficulty of management, causes manufacturing cost higher.How to improve production capacity and the efficiency of construction of adhesive waterproof coil, become technical problem urgently to be resolved hurrily.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of easy torn edges film for adhesive waterproof coil that can simplify limit film manufacturing procedure, reduce manufacture and construction cost.
Technical scheme: for solving the problems of the technologies described above, easy torn edges film for adhesive waterproof coil provided by the invention, the surface coating of described easy torn edges film and adhesive waterproof coil is integral, the edge part of described surface coating is shaped with indentation line, described limit film is formed on the surface coating outside indentation line, the bearing of trend of described indentation line and limit film to tear direction identical.
As preferably, for the ease of limit film and surface coating being torn, described indentation line has the bar hole of row's longitudinal direction.
As preferably, conveniently tear from end, described indentation line runs through the two ends of whole surface coating.
As preferably, described surface coating is elongated, and the long limit of described indentation line and strip is parallel to each other.
As preferably, the distance on described indentation line and long limit is 10 ~ 15cm.
As preferably, described surface coating is polyethylene film or polyester film.
The present invention proposes the construction method applying the easily adhesive waterproof coil of torn edges film as claimed in claim 1 simultaneously, comprises the following steps:
Step 1, rolls paving paving Article 1 watertight composition first along construction surface, tears after completing along the limit film of indentation line by Article 1 watertight composition upper surface;
Step 2, lay Article 2 watertight composition, and the edge of Article 2 watertight composition be overlapped on the edge of the Article 1 watertight composition removing limit film, the width of overlap edge is 10 ~ 15cm;
Step 3, the like lay the 3rd, Article 4 watertight composition, spread until surface of will construct is full, then roll extrusion carried out to the watertight composition after laying, make it bond firmly closely knit;
Step 4, carries out the process of receipts head, the termination of receiving head place coiled material is cut out neat after in press-in groove, and press solidly fixed with metal bead nail, interior the sealing compound of groove is obturaged, and dependence coiled material self viscous force is bonded in basic unit securely.
Beneficial effect: separation layer of the present invention adopts integrative-structure, overall can be overlying on the top layer of adhesive waterproof coil during fabrication, compare the technique that existing independent limit film needs twice overlay film, simplify material variety and equipment, improve continuity and the unit interval production capacity of production.As long as tear along indentation line the self-adhesion overlap joint that limit film just can carry out edge during construction, simple to operate.
