Description

Modified pitch root resistant waterproof roll

Technical field

The present invention relates to a kind of waterproof roll, be specifically related to a kind of modified pitch root resistant waterproof roll, the laminar product that to belong to special surface coating be feature.

Background technology

Planted roof comprises roof garden, underground garage end face is green plants, and has beautifying city view, purifies air, adjusting ambient temperature, reduces tropical island effect, makes full use of the advantages such as rainwater irrigation, enjoy people to praise highly.The waterproof of planted roof is different from common roof waterproof, requires to arrange twice waterproof: the watertight composition of resistance to plant root puncture together, together common watertight composition.The watertight composition of resistance to plant root puncture must use the satisfactory waterproof roll of resistance to plant root puncture to lay.Popularizing planting roofing, improves urban environment, and the work and the habitation environment quality that improve people are significant.

Through retrieval, Chinese patent literature CN201433516 discloses a planted roof self-adhesion root resistant waterproof roll and is sequentially made up of from the bottom to top lower barrier film, lower painting anti-root type self-adhesion glued membrane, root resistant waterproof roll, upper painting anti-root type self-adhesion glued membrane and upper barrier film.One in employing PE barrier film, PET barrier film, PVC barrier film, PP barrier film, PA barrier film, silicone oil paper film is as upper and lower barrier film; Root resistant waterproof roll is the one in metal tire base (pewter, complex copper tire base, Copper Foil tire, aluminium tire) waterproof roll, SBS (APP) modified pitch root resistant waterproof roll, root-resistant puncturing polyethylene tire polymer modified bituminous waterproof sheet material and root-resistant puncturing polyvinyl composite water-proof coiled material.It is by applying anti-root type self-adhesion glued membrane to the root resistant waterproof roll of different cultivars, the basis retaining original material property overcomes material monolithic anti-property difference, and the deficiency that manufacturing cost is high, makes again material have the feature of cold construction and moisture substrate operation.But because the fusing point of layers of material is all lower, be not suitable for using Hot-melt construction, developing a kind of modified pitch root resistant waterproof roll being applicable to Hot-melt construction has 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 modified pitch root resistant waterproof roll being applicable to Hot-melt construction.

Technical scheme: for solving the problems of the technologies described above, modified pitch root resistant waterproof roll provided by the invention, comprise polyester copper coin central core, the two sides of described polyester copper coin central core is all laid with modified pitch stopping area, the outer surface of described modified pitch stopping area is laid with PE film, and described PE film has aluminium coated.

Particularly, the outer surface of described PE film is also laid with screed.

Particularly, the thickness of described polyester copper coin is 0.1 ~ 0.5mm.

Particularly, the thickness of described modified pitch stopping area is 1.5 ~ 3mm.

Particularly, the thickness of a pair modified pitch stopping area of described polyester copper coin central core both sides is equal

Particularly, the edge of described PE film has edge sealing.

The present invention proposes the construction method of above-mentioned modified pitch root resistant waterproof roll simultaneously, comprises the following steps:

Step 1, base cleaning;

Step 2, at substrate surface even brushing bituminous neoprene adhesive;

Step 3, paving extra play, overlays a layer coiled material in pipe root, negative and positive angular position;

Step 4, with full bonding rolling paving coiled material, heats simultaneously and makes asphalt temperature keep being 200 ~ 250 DEG C;

Step 5, hot melt edge sealing, coiled material lapping seam place spray gun heats, and is pressure bonded to edge and extrudes pitch and cement;

Step 6, protective layer is constructed, and when water-proofing treatment surface is plane, protects waterproof material with pea gravel concreten protective layer; When water-proofing treatment surface is facade, smear 20mm solid cement mortar on its surface.

Beneficial effect: modified pitch root resistant waterproof roll of the present invention has following beneficial effect:

1. adopt symmetrical structure, two-way all possess the effect of waterproof root resistance, is applicable to various planting environment.

2. the heat resistance of layers of material is good, and thermal conductivity factor is high, is applicable to Hot-melt construction, easy construction and hot seam more reliable durable;

3. tensile strength is large, to base-layer contraction, distortion, cracking adaptable.

Detailed description of the invention

Embodiment: the modified pitch root resistant waterproof roll of the present embodiment as depicted in figs. 1 and 2, comprise the polyester copper coin central core 1 of 0.1 ~ 0.5mm, the first modified pitch stopping area 2-1 and the second modified pitch stopping area 2-2 is laid with respectively on the two sides of polyester copper coin central core, a PE film 3-1 is laid with at the outer surface of the first modified pitch stopping area 2-1, be laid with the 2nd PE film 3-2 at the outer surface of the second modified pitch stopping area 2-2, the inner surface of a PE film 3-1 and the 2nd PE film 3-2 all has aluminium coated.And lay screed 4 at the upper surface of the 2nd PE film 3-2.Wherein, the buying of modified pitch stopping area, from commercially available modified pitch root resistance coiled material, is that the SBS/APP modified pitch that with the addition of chemical root resistance agent is the coiled material of coating material with polyester fiber felt for tire base.

During use, comprise the following steps:

1. construction is front by clean for the pending base cleaning of acceptance(check).

2. brushing base treatment agent: at substrate surface even brushing bituminous neoprene adhesive.

3. paving extra play: overlay a layer coiled material in pipe root, negative and positive angular position.By specification and designing requirement, coiled material is cut into corresponding shape and carries out paving.

4. paving coiled material: modified asphalt waterproof coiled material is carried out cutting by paving length and spools for subsequent use, the coiled material will spooled during operation, the volume heart is penetrated with the pipe of φ 30, coil end is than the starting point starting together to spread, adopt special flame gun, heating basic unit and coiled material junction, spray gun keeps the distance of about 300mm apart from heating surface, come and go spray to bake, observe when the pitch of coiled material just melts, slowly roll forward laying in hand steered die two ends, require firmly evenly, not to choke with resentment, laying flanging width should grasp.Paving mode is full bonding, and lap width is 100mm.

5. hot melt edge sealing: coiled material lapping seam place spray gun heats, is pressure bonded to edge and extrudes pitch and cement.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, the interior sealing compound of groove is obturaged.

6. protective layer construction: when water-proofing treatment surface is plane, with pea gravel concreten protective layer, waterproof material is protected.When water-proofing treatment surface is facade, smear 20mm solid cement mortar on its surface.

The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
