Roofing, basement, interior, municipal works and cistern, swimming pool and subway tunnel waterproof, apply also for timber structure and gold
Belong to the waterproofing work of structure roofing, the military installations for being particularly suitable for needing cold construction and the oil depot that should not employ naked light, change
The waterproofing works such as factory, textile mills, grain depot.
Adhesive waterproof coil throws off surface isolation film under the conditions of normal construction, exposes self-adhesion sizing material, then again with basic unit
It is bonded, forms one layer of waterproof layer.But there are floating ash, the situation that basic unit is moist or temperature is relatively low on basic unit's out-of-flatness, surface
Under, it may appear that adhesive waterproof coil loosely, easily forms hollowing phenomenon, and can form a tunic not at basic unit interface with base adhesive
Can be perfect Nian Jie with basic unit, it that is to say that after coiled material is stripped down from basic unit after constructing be interface unbound, it is impossible to stayed in basic unit
Lower modified pitch material, so as to influence waterproof effect.
The content of the invention
The defects of for existing adhesive waterproof coil, present inventor roll up self-adhesion waterproof by a large amount of creative researches
The composition of material is improved, so that a kind of adhesive waterproof coil with high tack has been invented, adhesive waterproof coil tool
Have good tack, have a little dust in substrate surface, wet base and temperature it is relatively low in the case of can be carried out with basic unit
Good bonding, and be not easily stripped after being bonded, it can ensure to leave complete modified pitch material in basic unit after stripping, it is ensured that
Still there is higher water resistance.
Based on foregoing invention, applicant completes the present invention, and the present invention is achieved through the following technical solutions:
A kind of high tack adhesive waterproof coil, comprising following component, by percentage to the quality:Asphalt 35%~
55%, softening agent 5%~25%, modifying agent 5%~25%, tackifier 2%~8%, interfacial agents 0.1%~2%, antioxidant

Preferably, the dosage of each component is, by percentage to the quality:Asphalt 40%~55%, softening agent 10%~
17%, modifying agent 10%~20%, tackifier 3%~6%, interfacial agents 0.5%~1%, antioxidant 1%~2%, filler
10%~20%.
It is further preferred that the dosage of each component is, by percentage to the quality:Asphalt 50%, softening agent 15%, modifying agent
13%, tackifier 5%, interfacial agents 0.8%, antioxidant 1.2%, filler 15%.
In the further detailed description of the present invention and specific implementation, the preferred type of various composition used is disclosed, with
Just more preferable, the clearer description present invention, but this detailed description does not form the special limitation to the present invention, not against this
A little detailed information and use other general chemical materials of technical field, as long as to meet the present invention above-mentioned to each composition for it
The restriction that Components Name is done, still belongs to protection scope of the present invention.
In the present invention, the asphalt is naphthene crude oils bitumen A level, and needle penetration is 70~200, in terms of 0.1mm.
In the present invention, the use of various auxiliary materials is not particularly restricted, every to meet chemically defined title

In order to embody " high tack " defined in the present invention, the present invention is issued using State Administration for Quality Supervision and Inspection and Quarantine
Standard GBT 4852-2002《Pressure-sensitive adhesive band tack test method (rolling ball method)》Carry out, test method is as follows:
Before preparing sample, self-adhesive asphalt waterproof coiled material should remove packaging material, non-overlapping copies in sample room temperature humidity bar
More than when (21 DEG C~25 DEG C of temperature, humidity 60%~70%) placement 2 is small under part.
Sample:Specimen width is 10~80mm, and length about 250mm, its separation layer is thrown off with the speed of about 300mm/min,
A sample is intercepted every 200mm or so, takes more than 4.When sample stretcher strain is larger, it is allowed to have parking no more than 3min
Time, makes its recovery.Hand or other objects are not allowed to contact sample testing section during sampling.
Inclined-plane grounder device is by that can tilt 20 °, and 30 °, 40 ° of hang plate and its draw bail form, as shown in Figure 1, respectively
Part is as follows:Hang plate 2 is installed on the stent 10 of base 1, and hang plate uses smooth rigid planar plate (glass plate, metal
Plate, plank, plastic plate etc.), opposite with hang plate is box 3 of receiving.In order to adjust the inclination angle of hang plate, angle is equipped with stent
Spend adjusting knob 11;In order to adjust position of the steel ball on hang plate, 20 position of ball device is put equipped with before and after steel ball in hang plate upper end
Position adjusting knob 21, steel ball right position adjusting knob 22.Be also equipped with base air level 12 be used for calibrate to straight.
Wherein, rolling more than Duan Youchang 100mm are helped, transparent polyester film about 25 μm thick, is pasted on certainly in defined position
Formed on viscous coiled material.Help rolling segment length 100mm.
Measure Duan Weicong helps rolling section lower end to start to count, and length is the gluing surface in the range of 100mm.
For spin material with GCr15 bearing steel makings, the precision grade of steel ball form tolerance and surface roughness should reach GB/
Class 4 more than 0 as defined in T 308.The ball number of spin is shown in Table 1 with corresponding nominal diameter.
The ball number of 1 spin of table and corresponding nominal diameter
Test method:
Grounder device is horizontally fixed on testboard with level meter, inclined plane takes 30 ° of standard angle.Also may be used when needing
To take 20 ° or 40 °.
In the lower end of self-adhesive coiled material sample respectively with adhesive tape or counterweight (quality about 500g) is positioned, by sample with gluing surface
Upward mode is fixed on defined position.Helping rolling section to be sticked on poly-vinegar film on the assigned position of sample gluing surface,
It bubble is mingled with or is wrinkled when sticking poly-vinegar film, also not add big pressure.In fixed sample, it is careful not to
It is allowed to that warpage occurs or heaves.If being heaved in marginal portion, this part is fixed on inclined plane using other adhesive tape
On.
It is 100mm to make to help the consistent length of rolling section, according to the size of ball, as shown in Figure 1, ball center is adjusted in ball
On initial position.
The ball that will be stored in antirust agent, is taken out with tweezers, is dipped in alcohol washes steel ball with gauze, after cleaning, has been placed on
On beginning position, with different size of ball, the sequence of operations such as cleaning, the rolling of ball are repeated, it is (stone-dead in measure section from stopping at
Up to more than 5s) each bulb in choose maximum.Take out the biggest ball that is found in same test piece and the ball number is adjacent thereto
Two balls of size, are respectively once tested in same sample, to confirm the steel ball of biggest ball number.
In order to verify the beneficial effect of the high tack self-adhesive asphalt waterproof coiled material of the present invention, based on above-mentioned detection method to reality
The tack for applying the self-adhesive asphalt waterproof coiled material of the preparation of example 1~4 is tested.Result of the test is shown in Table 2.
