With the rapid development of urban construction and infrastructure construction in China, the waterproof roll is gradually applied to the fields of buildings, bridges and tunnels, traffic transportation and the like. The waterproof coiled material product mainly comprises an asphalt type waterproof coiled material and a high polymer type waterproof coiled material. However, the asphalt type waterproof roll requires a hot melting method during construction, which causes asphalt contamination and also damages the health of the constructors. In recent years, most cities have banned the use of this process for the production of waterproofing rolls.
The high-molecular waterproof coiled material is mainly prepared by using synthetic resin, synthetic rubber or a mixture of the synthetic resin and the synthetic rubber as a matrix, adding chemical auxiliaries and fillers, and carrying out calendering, extrusion, banburying and other methods. The high-molecular waterproof coiled material has the advantages of high tensile strength, high tear strength, good heat resistance, good homogeneity, good low-temperature flexibility and the like. And by adding the chemical additives and the fillers, the aging resistance and the oxidation resistance of the high-molecular waterproof roll can be improved. Therefore, the polymer waterproof roll becomes the main force of the future waterproof roll.
