High polymer modified bitumen waterproof membrane is modified asphalt for coil coating materials. Normal asphalt can become hard and brittle materials in low temperature, cracks, temperature sensitivity, and under the action of UV light from the sun light for a long time, summer heat to soften, resulting in pyrolysis flows, caused by repeated expansion and contraction of change of stress in asphalt. In the presence of oxygen and ozone, such as comprehensive, and chemical composition of asphalt in the ever-changing results, first oil volatile, lipid gel content of asphalt, plastic drop, fragile, bond reduced cracking and aging. For these reasons, so the traditional asphalt waterproof material to meet the needs of building waterproof and durable life, since in the mid 1970 of the 20th century began the development of synthetic polymer modified asphalt. Add a certain amount of polymer modified asphalt, and asphalt inherent brittle at low temperature cracking, degradation of high temperature flow can be improved, modified asphalt not only has good low and high temperature performance, but also has good elastic-plastic, such as hydrophobicity and adhesion. High polymer modified asphalt waterproofing roll-roofing and asphalt waterproofing membrane compared to the tensile strength of modified asphalt waterproofing roll-roofing, heat resistance and low temperature flexibility will enhance, and has good impermeability and resistance to corrosion.
High polymer modified bitumen waterproof membrane is using new type waterproof materials with high percentages of products, now has become one of the leading products of waterproofing membrane, is a medium and high-grade waterproof materials, with polyester carcass coil mat for optimal performance, with high tensile strength and high elongation low fatigue strength characteristics.
Polymer modified asphalt waterproof coiled material its characteristic is the use of the play without good performance, improved asphalt hot dripping cold and brittle, so as to improve the technical performance of asphalt waterproofing membrane.
