Abstract

The invention relates to a PE composite modified asphalt waterproof coil material and a preparation method thereof. The material sequentially comprises an upper surface isolation layer, an upper polymer modified asphalt layer, a base layer, a lower polymer modified asphalt layer and a lower surface isolation layer from top to bottom, wherein the upper polymer modified asphalt layer and the lower polymer modified asphalt layer are prepared from PE composite modified asphalt; the PE composite modified asphalt comprises, by weight, 70-80 parts of petroleum asphalt, 20-30 parts of polyethylene, 10-15 parts of SBS rubber, 10-15 parts of furan resin, 3-5 parts of pentaerythritol stearate, 0.1-0.3 part of graphene, 1-3 parts of sodium dodecyl benzene sulfonate, 1-3 parts of sodium oleate, 5-8 parts of paraffin, 1 part of zinc ethylphenyl dithiocarbamate, 0.5 part of phthalic anhydride, 1 part of sulfur, 0.6 part of petroleum sulfonate, 1-3 parts of butanedioic anhydride, 3-5 parts of methyl cellulose and 1-3 parts of pyroligneous liquor. The prepared waterproof coil material has good high- and low-temperature performance and storage stability, effectively improved waterproofness, effectively improved ageing resistance, and prolonged service lifetime.

Description

technical field [0001] The invention relates to a PE composite modified asphalt waterproof coiled material and a preparation method thereof, belonging to the field of waterproof coiled materials. Background technique [0002] Waterproof materials are essential materials to protect building safety and service life. Waterproof engineering is an important sub-project in construction engineering. It is used in building underground, roof, roof, wall kitchen, toilet, subway, railway, water conservancy and industrial buildings. . Building waterproofing is an important technical measure to ensure that buildings are waterproof, dustproof, leak-proof, energy-saving and heat-resistant, thereby prolonging the service life of buildings. At the same time, it plays an important role in building safety and personal safety, and is more related to social unity and stability. Polymer modified asphalt waterproofing membrane is produced by compounding polyester carcass, glass fiber carcass or t...
