Abstract

The invention relates to a root penetration-resistant self-adhesive polymer modified asphalt waterproof coiled material which comprises an upper isolation layer, a base layer and a lower isolation layer, wherein the two surfaces of the base layer are coated with modified asphalt mastic; and the modified asphalt mastic is prepared from the following raw materials in parts by weight: 100-105 parts of petroleum asphalt, 8-12 parts of butadiene styrene rubber, 6-8 parts of SBS, 10-15 parts of modified nano-zinc oxide, 6-8 parts of coumarone resin, 1-2 parts of octyl epoxy stearate, 10-15 parts ofmodified fly ash fiber powder, 3-5 parts of an antioxidant and 1-5 parts of a stabilizer. The specially modified nano-zinc oxide and fly ash fiber powder are added into the modified asphalt used in the waterproof coiled material, so that the waterproof coiled material has excellent root penetration resistance.

Description

technical field [0001] The invention relates to the technical field of waterproof coiled material, in particular to a root puncture-resistant self-adhesive polymer modified asphalt waterproof coiled material. Background technique [0002] As modern people pay more attention to environmental greening, more and more planted roofs appear in urban construction. The waterproofing of planted roofs has always been a subject that people have paid attention to. Once the planted roof leaks and other problems, it will seriously affect the buildings under the vegetation, and it is very difficult to repair. [0003] The planted roof is a roof that covers the waterproof layer of the roof with soil or lays sawdust, vermiculite and other loose materials, and plants are planted to play a role in heat insulation. Planting soil is spread on the waterproof layer of the roof of the building and the roof of the underground project, and plants are planted to make the roof play the role of waterpr...
