Abstract

The invention discloses an ethylene-propylene-diene monomer modified bitumen waterproof coiled material and a preparation method thereof. The ethylene-propylene-diene monomer modified bitumen waterproof coiled material is prepared by taking bitumen as a base stock and adding an ethylene-propylene-diene monomer, an SBS (styrene butadiene styrene block copolymer) sizing material, a reinforcing agent and the like. The ethylene-propylene-diene monomer modified bitumen waterproof coiled material provided by the invention has lots of excellent integrated economic and technical performance indexes such as excellent waterproofing, flame retardance, seepage resistance, weather resistance, high tensile strength, high percentage of elongation, ageing resistance, well deformation adaptability, wide temperature application range, high cementation, long service life, easy construction and low cost of construction. The ethylene-propylene-diene monomer modified bitumen waterproof coiled material can be used for waterproof engineering of building roofs, bridge floor concrete, undergrounds, roads and the like.

Description

technical field [0001] The invention belongs to the field of building waterproof materials, and in particular relates to an EPDM modified asphalt waterproof coiled material and a preparation method thereof. Background technique [0002] Waterproof membrane is a commonly used building material in building construction. In underground engineering and bridge engineering, waterproof membrane can effectively reduce leakage and protect the main structure of the building. The existing EPDM waterproofing membrane has excellent properties such as high strength, high elongation, high tear strength, high and low temperature resistance, ozone resistance, and aging resistance, so it is widely used in building construction. However, after the existing EPDM waterproofing membrane is laid, water channeling and water seepage are prone to occur due to poor adhesion between the waterproofing membrane and the building base. Contents of the invention [0003] The purpose of the present invent...
