Body is related to a kind of oil-extended SBS modified asphalt waterproof coiled material technique and preparation method thereof.
Background technique
The period ot batching of current domestic modified bituminous pitch coiled material is longer, generally (5.5-7.5) h, especially SBS content compared with
In high product, need to grind (1.5-2) h, especially domestic asphalt felt production line, colloid mill grinding effect by colloid mill
Fruit is poor, and batch temperature is up to 210 DEG C, and at such high temperatures, modified pitch aging is serious, and be easy to cause pill tank spontaneous combustion
Phenomenon brings huge hidden danger to safety in production.
The existing plastics phase polystyrene section of Styrene-Butadiene-Styrene Block Copolymer (SBS), and have rubber gathering
Butadiene section.The objectionable intermingling in the presence of the two is with certain proportion, micron-scale phase separation, two-phase interface are clear.Polystyrene section phase
Mutually association forms physics crosslinking points, makes it without vulcanizing intensity i.e. with higher.
Current SBS is divided into star-like and line style according to its micro molecule chain structure, and the SBS of hub-and-spoke configuration compares linear structure
SBS has more preferably wearability, resilience, tear resistance etc., but the SBS of hub-and-spoke configuration is than the SBS mobility of linear structure
Difference, it more difficult in processing.It is star-like also than the difference of line style in terms of tensile property.Star-like SBS is more suitable for elastomer SBS coiled material
The application of class is not suitable for the application of asphalt paint, self-adhesive coiled material.
For above situation, the present inventor has found that star-shaped sbs are on elastomer asphalt felt in many years practice
Application in, suitable modifying agent in collocation has a significant improvement to coiled material, and preferably a kind of oil-extended SBS modified pitch is prevented out
