Abstract

The invention relates to a modified asphalt waterproofing coiled material with a self-adhering layer and a preparation method thereof and belongs to the technical field of building waterproofing coiled materials. The modified asphalt waterproofing coiled material comprises a polyester base, and an asphalt layer and a self-adhering layer which are formed by the polyester base in a dip-coating manner, wherein the self-adhering layer is prepared from the following ingredients in parts by weight: asphalt 90#, rubber powder, SBS (Styrene Butadiene Styrene block polymer), SBR (Styrene Butadiene Rubber), hydrogenated petroleum resin, naphthenic oil, rock flour, an ultraviolet absorbent and an antioxidant; the asphalt layer is prepared from the following ingredients in parts by weight: asphalt 10#, asphalt 90#, nylon powder, SBS, APP (Ammonium Polyphosphate), PP (polypropylene), cut 3 engine oil and rock flour. The modified asphalt waterproofing coiled material has the advantages of good waterproof performance, ageing resistance, high tensile strength, good extensibility and excellent low-temperature flexibility and heat resistance.

Description

Technical field [0001] The invention belongs to the technical field of building waterproof coiled materials, and specifically relates to a modified asphalt waterproof coiled material with a self-adhesive layer and a preparation method thereof. Background technique [0002] Waterproof coiled material is mainly used for building walls, roofs, tunnels, highways, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into a roll, as the foundation of the project The leak-free connection with the building is the first barrier to waterproof the entire project and plays a vital role in the entire project.
