To conventional asphalt waterproofing effect is not very good, easy flowing high temperature, low-temperature cracking up less than waterproof, best results with the technology development and progress. Asphalt waterproof basically modified asphalt waterproofing membrane epoxy asphalt paint. Added on the basis of the asphalt modifier to improve the asphalt head a technical indicators to achieve the best results of the asphalt, most of the bituminous material is coated onto the surface after heating to play a waterproofing effect. Does not require heating the direct construction, such as solvent at room temperature, asphalt and emulsified asphalt. Polymer modified asphalt is a polymer modified asphalt products for the modifier. Modification, can greatly improve the physical and mechanical properties of bituminous waterproofing materials, which is one of the direction of asphalt in the construction waterproofing applications. The most used two kinds of SBS rubber and APP resins In addition, chloroprene rubber, butyl rubber and EPDM rubber and so on. These polymer molecular weight, molecular polar groups and active groups, is relatively stable, has a brittle point temperature, high melting temperature, high and low temperature adaptability, anti-aging properties to good advantage, therefore, can improve the asphalt high and low temperature properties and aging resistance.
