Problems solved by technology

[0002] Styrene, butadiene copolymer rubber (SBS) modified asphalt is the best and most widely used modified asphalt material in the world so far, but it can only be used to produce waterproof sheets and solvent-based coatings in China, not water-based Environmentally Friendly Coatings
Because the asphalt modified by SBS is difficult to be emulsified, it is difficult to make SBS water-based paint with high solid content
The existing domestic modified asphalt coatings all use water-based latex to modify the asphalt. The cost is high, the solid content is low, and the indicators of the finished product cannot meet the waterproof requirements, such as: elasticity, elongation, high and low temperature performance, etc.
