The contrast of company standard of sticking modified asphalt waterproof coiled material provided by the invention " Q/FSWJG004-2008 sticking modified asphalt waterproof coiled material " and national standard " GB18242-2000 elastomer modified asphalt waterproof roll (heat molten type) " and industry standard " JC898-2002 self-adhesive polymer modified bituminous polyester fiber waterproof sheet material (self-adhering-type) ".
The physical property technical indicator of the modified asphalt waterproof coiled material that requires in three kinds of standards of table 3.
Technical indicator in the one series products standard is the technical indicator that this series products must reach, and also is the representative of such product quality.
(1). the contrast of physical and mechanical property:
As can be seen from Table 3: in three kinds of standards, the impermeability of " Q/FSWJG004-2008 sticking modified asphalt waterproof coiled material " (sequence number 2), in length and breadth to pulling force (sequence number 4), elongation per unit length (sequence number 5) and tearing strength (sequence number 7) all are higher than the relevant art index in " Jc898-2002 self-adhesive polymer modified bituminous polyester fiber waterproof sheet material " during in length and breadth to maximum pull.Wherein, impermeability (sequence number 2), all be higher than " the relevant art index in " GB18242-2000 elastomer modified asphalt waterproof roll " to pulling force (sequence number 4) and tearing strength (sequence number 7) in length and breadth.Therefore, three kinds of standard techniques indexs show in the table 3: aspect physical and mechanical property, sticking modified asphalt waterproof coiled material provided by the invention is better than other two kinds of modified asphalt waterproof coiled materials.
(2). the low temperature bonding property comparison:
As can be seen from Table 3: in three kinds of standards, do not have caking property under " GB18242-2000 elastomer modified asphalt waterproof roll " normal temperature, so cutting performance (sequence number 8) and stripping performance (sequence number 9) do not have corresponding data to compare.The cutting performance of " Q/FSWJG004-2008 sticking modified asphalt waterproof coiled material " (sequence number 8) is identical with the relevant art index of " Jc898-2002 self-adhesive polymer modified bituminous polyester fiber waterproof sheet material " with stripping performance (sequence number 9), and promptly both bond effects are the same.But this is the data that record under environment temperature is 23 ℃ ± 2 ℃ condition.From the 4th of national standard " GB50345-2004 Technical code for roof engineering " 5.6.6: " coiled material of paving should be smooth straight, and the overlap joint size is accurate, must not twist, fold.During low-temperature construction, facade, macrodome and overlapping part should adopt the unit heater heating, paste firmly immediately after the heating ".Above-mentioned record about self-adhesion method paving coiled material shows: self-adhesive waterproof web adhesion stress in low temperature environment descends or forfeiture, needs to adopt hot melt could paste firm and solid.And bonding adhesive provided by the invention is still liquid in the time of-15 ℃, and adhesion stress does not obviously go down.Therefore, it is fully feasible that sticking modified asphalt waterproof coiled material provided by the invention is constructed in the environment more than-10 ℃, has realized the northern China wide geographic area flames of anger in winter construction.
Embodiment 9
Sticking modified asphalt waterproof coiled material provided by the invention and bonding adhesive have all added affinity agent, and mutual compatibility is between the two strengthened greatly, thereby have improved the adhesion stress between sticking modified asphalt waterproof coiled material and the bonding adhesive.In addition, bonding adhesive provided by the invention itself has water-proof function, and adhesion stress does not descend substantially under cold environmental conditions.So, during the supporting application of sticking modified asphalt waterproof coiled material provided by the invention and bonding adhesive, have following advantage:
1), do not need heat construction, can not cause security incident;
2), coiled material need not roast, quality can not sustain damage;
3), the complex region (also being the position that needs the emphasis waterproof) of building and the direct breakthrough of basic unit, as the crack sand holes on the concrete base layer, pore etc., do extra play with bonding adhesive provided by the invention, construction is simple, good water-proof effect;
5), the overlap joint between coiled material and coiled material is tight, is not prone to seepy question;
6), paste firmly between coiled material and basic unit, effectively prevented the appearance of breakthrough.
7), coiled material do not cover barrier film, reduced the cost of coiled material and construction, and avoids producing construction rubbish;
3), the construction influenced by ambient temperature little, environment temperature all can be constructed in the time of-10～60 ℃;
4), the adhesion stress of coiled material is strong, do not need to fix with cement nail during the facade construction, can not destroy the waterproof effect of coiled material.
Sticking modified asphalt waterproof coiled material and bonding adhesive can carry out when being used in the waterproofing of the basement of construction work, roofing and highway bridge, subway, railway bridges and culverts as follows:
(1). basic unit's arrangement: basic level requirement is smooth, clean, nothing is floated sand, floating dust, cement-free pimple, no obvious water mark on the wet base face.
(2). do extra play: the complex region of the direct leak source in the basic unit, the position that crack or distortion may occur and building is all made a cloth two and is coated with extra play.
(3). the shop coating adhesive: press and draw good lines shop coating adhesive in advance, smoothen directly, no holiday leaks scrapes phenomenon, does not have and piles up phenomenon, dries about 10～30 minutes, is advisable with tack-free finger.
(4). the paving coiled material: by drawing good lines paving coiled material, the shop is directly paved.
(5). the coiled material compacting fastens: by the order of first intermediate and then both sides with beaming roller with the coiled material compacting, fasten, and get rid of air between coiled material and the bonding adhesive.
(6). coiled material sealing: the seam between coiled material and the coiled material should be less than 1mm, and sticks with glue agent and paste sealing.
(7). the sealing of coil edge: after installation of membrane is finished, polyesters nonwoven and polyethylene film, aluminium foil or the polyesters nonwoven of coiled material are pasted, sturdy subsides jail, and stick with glue the agent sealing.
(8). after waterproofing course is carried out, do and drench the retaining test, pinpoint the problems and in time handle.
