Polymer modified asphalt waterproof sheet is made of polyester felt as the base, styrene-butadiene-styrene (SBS) thermoplastic elastomer, random polypropylene or random polyolefin (APP) plastic body as the modifier, and is covered with fine sand, polyethylene film, mineral particles and other insulating materials.
?
Product type
?
● The products are divided into self-adhesive (Z), hot melt (R) or hot melt adhesive (J) construction waterproof coil according to the construction method.
?
● Hot melt or hot melt adhesive construction waterproof coil is divided into elastomer (SBS), plastic body (APP) modified asphalt waterproof material according to the different modified materials.
?
The self-adhesive construction waterproof coil is a rubber modified asphalt waterproof coil with SBS as the main part and other polymers.
?
● APP modified asphalt waterproof coil is divided into type I and type II according to different forms of asphalt paving layer.
?
The top surface material of the coil is fine sand (S).
?
Hot melt construction waterproof coil according to the surface material is divided into: polyethylene film (PE), fine sand (S).
?
The bottom surface material of hot melt adhesive waterproof coil is fine sand (S).
?
peculiarity
?
● All features of APP/SBS.
?
● It has high heat resistance, good high temperature shear resistance, and can ensure that the waterproof layer is not destroyed when the high heat asphalt concrete is spread.
?
● Strong resistance to crushes, able to withstand the puncture of bare grinding equipment and granular materials during construction.
?
● High tensile strength, high elongation, high bond strength with concrete.
?
● No foaming stratification, good impervious water, can withstand the repeated action of driving and dynamic water pressure.
?
● Acid, alkali, salt resistance is not affected by freeze-thaw cycle.
?
● Good anti-aging and anti-fatigue performance.
?
Scope of application
?
Self-adhesive, SBS, APPl type coil is mainly used for paving asphalt concrete. APP I I coil is mainly used for paving of cast asphalt concrete mixture.
?
Storage and transportation instructions
?
● When storing and transporting, different types and specifications of products should be placed separately, and should not be mixed. Avoid sun and rain, pay attention to ventilation.
?
● Hot melt or hot melt adhesive waterproof coil should be placed below 50℃, its height does not exceed two layers.
?
● Self-adhesive waterproof coil can only be placed in a single layer, and the box can be placed flat. No more than five stories high.
?
● Under normal transportation and storage conditions, the storage period is at least one year from the production date.
?
Engineering properties of high polymer modified asphalt waterproof coil
?
● Polymer modified asphalt waterproof coil can withstand the rolling construction of hot asphalt concrete at high temperature, and has strong bond strength with hot asphalt concrete, and can transfer heavy traffic horizontal load.
?
● High polymer modified asphalt waterproof coil toughness, asphalt concrete has the function of strengthening the backing, can effectively prevent the generation and development of asphalt concrete cracks, improve the service life of asphalt concrete pavement and the comfort of vehicles.
?
● The waterproof performance of the polymer modified asphalt waterproof coil: the cracks and void water of the asphalt concrete surface layer on the road and bridge will produce a huge "tube" pressure water effect under the action of driving load, which will protect the reinforced concrete structure.
?
● The strength, elongation and high and low temperature performance of polymer modified asphalt waterproof coil are better than ordinary self-adhesive, SBS and APP waterproof coil, and ordinary self-adhesive, SBS and APP coil must not be used on the road.
