Abstract

The invention provides a non-asphalt-based polymer self-adhesive waterproof membrane, the tensile strength is 5.1-5.4MPa, and the elongation at break is 706-716%. When the folding angle is 15 degrees and the number of folding times is 5 times, the bending The tensile strength at 4.9-5.2 MPa, the elongation at break is 688-692%; the waterproof membrane includes a polymer homogeneous sheet layer: raw materials include: LDPE, HDPP, melamine and its salt, waste reclaimed rubber powder, star-shaped SBS, rosin-modified phenolic resin, polyacrylonitrile fiber, repolymerization modifier and accelerator; the non-bitumen-based polymer self-adhesive waterproof membrane of the present invention is not only full of elasticity, but also has remarkable sound absorption Noise reduction effect; good bending resistance, the folding angle can reach 15 degrees without water leakage, and the mechanical properties of the bending place are almost not reduced, especially suitable for waterproofing of curved surface projects such as pipelines, tunnels, bridges and culverts.

Description

technical field [0001] The invention belongs to the technical field of waterproof coiled materials, and relates to a non-asphalt-based polymer self-adhesive waterproof coiled material, in particular to a non-asphalt-based polymer self-adhesive waterproof coiled material and a preparation method thereof. Background technique [0002] Asphalt-based polymer self-adhesive waterproofing membrane has the disadvantages of easy aging and brittleness when heated, inconsistent thermal expansion and cold contraction with cement roofing or metal roofing, easy delamination, and affecting waterproofing effect. In addition, asphalt often contains naphthalene, anthracene, pyridine, phenol and other toxic substances, which will emit a strong smell, pollute the environment, strongly stimulate the skin and mucous membranes, have phototoxic and carcinogenic effects, and are not conducive to health and environmental protection. [0003] At present, the existing non-bitumen-based polymer self-adh...
