The invention discloses an ultra-low temperature self-adhesive rubber-asphalt polymer composite waterproofing membrane, which belongs to the technical field of waterproof materials and comprises a tire base, an asphalt layer and an isolation layer, wherein the asphalt layer includes the following raw materials in parts by weight: 55-65 parts of matrix asphalt , 20-28 parts of rubber oil, 15-18 parts of SBS elastomer, 2-3 parts of additives, 12-14 parts of talc, and 0.2-0.3 parts of antioxidant 4010. In the present invention, by adding additives to the asphalt material, the surface tension and surface free energy of the asphalt molecules can be reduced to reduce the temperature of asphalt heating and mixing; the addition of the additives can improve the flexibility of the asphalt molecules, improve the low-temperature flexibility of the asphalt, and improve the asphalt. The addition of additives can also effectively improve the flammable characteristics of asphalt and improve the flame retardant performance of asphalt materials; the obtained asphalt materials have excellent ultra-low temperature resistance and flame retardant properties, which can be used in extremely cold regions. use. |
