According to the present invention, the obtained heat-resistance and saline-alkaline-resistance type elastomer modified bitumen waterproof coil material has characteristics of excellent heat resistance and excellent saline-alkaline resistance.

Description

technical field [0001] The invention relates to a waterproof coiled material, in particular to a heat-resistant, salt-alkali-resistant elastomer modified asphalt waterproof coiled material. Background technique [0002] With the improvement of construction technology, the demand for waterproof materials for construction projects is increasing, and the quality requirements are also getting higher and higher. With the progress of various engineering constructions, the problem of water seepage and leakage on roofs, floors, and basements has always plagued people. As a result, waterproof projects have emerged as the times require, and various waterproof materials have emerged in an endless stream, and the waterproof industry has flourished. Waterproof membranes are widely used in the construction industry and are one of the important building materials. The existing self-adhesive membranes and modified asphalt membranes are relatively common. Although the self-adhesive membranes...

Problems solved by technology

Waterproof membranes are widely used in the construction industry and are one of the important building materials. The existing self-adhesive membranes and modified asphalt membranes are relatively common. Although the self-adhesive membranes have good flexibility and adhesion Viscous, easy to bend, and convenient for construction, but its tensile strength is poor, its elongation at break is low, and its self-healing ability is weak; among them, although the modified asphalt coil has high strength, its viscosity is poor, and in Poor application effect in high temperature areas, no self-healing function, poor elongation at break, and no self-adhesiveness

[0003] In addition, the existing waterproof membranes have poor heat resistance and salt-alkali resistance, which directly affects the construction efficiency and cannot meet the construction needs of high-temperature and saline-alkali areas. Therefore, a waterproof membrane with better heat-resistant, saline-alkali and alkali resistance has been developed. It is ready to be used in high temperature environment and saline environment
