Build in the construction of thing, be required to the most paved waterproof roll.And waterproof roll conventional at present is high molecular polymer modification drip
Green grass or young crops, according to the difference in place of waterproof roll application, needs the property certain to waterproof roll, such as in coastal area and
High salinity area, because by saline and alkaline erosion, the waterproofing work of building requires higher than general building waterproof standard, especially
Require that waterproof material to have excellent saline-alkaline corrosion-resistant performance and resistance of chloride ion penetration, can be in high salinity environment for a long time
In still keep good water resistance, it is possible to opposing high temperature and severe cold.High application places is required, it is desirable to required in fire-protection rating
Waterproof roll has certain fire retardant performance, and the fire retardant performance of common modified pitch of high polymer is poor,
Can not reach to use requirement.
In structural fire protection safety, Colophonium is a place that can not avoid, owing to Colophonium is combustible material, it is easy to because of
Catch fire for the traffic fire in building, be that the extent of injury of fire is upgraded further.During Colophonium burning, first melt, drip, flow
Drop down, be followed by bead burning, after-combustion bead drippage, trickling, cause fire spreading to expand, Colophonium divides in combustion
Solving the inflammable gases such as methane, the existence of these inflammable gases has encouraged again the intensity of a fire.Therefore, the fire that Colophonium class material combustion causes
Calamity has the advantages that the oncoming force is violent, diffusion is fast, smog is big, thus limits modified pitch base waterproof roll and build in special fire protection requirement
Build the use on thing.
Research and development have the polymer modified asphalt water-proof coiled material product of high flame resistance, can be greatly improved us
