According to different main composition materials, the waterproof material is divided into an asphalt waterproof coiled material, a high polymer modified asphalt waterproof coiled material and a synthetic polymer waterproof coiled material; the coiled materials are divided into coiled materials without a matrix, coiled materials with a paper matrix, coiled materials with a glass fiber matrix, coiled materials with a glass cloth matrix and coiled materials with a polyethylene matrix according to different matrixes.
The waterproof roll is required to have good water resistance, stability to temperature change (no flow, no bubble, no disturbance and no brittle fracture at high temperature), certain mechanical strength, extensibility and fracture resistance, certain flexibility and aging resistance and the like.
The polymer self-adhesive waterproof coiled material (with the self-adhesive layer) has the characteristics of the polymer waterproof coiled material (such as high tensile strength, high elongation at break, high tearing strength, long service life and the like), and also has the advantages of self-adhesiveness, self-healing property, creep property, convenience and rapidness in construction operation, safety, environmental protection, no environmental pollution and the like which are unique to the self-adhesive waterproof coiled material. Therefore, the waterproof coiled material has better waterproof efficiency and is widely applied to the fields of buildings, traffic waterproofing and the like.
