Abstract

The invention discloses a self-vulcanized modified asphalt waterproof coiled material, and the material sequentially comprises a lower surface anti-sticking layer, a lower self-vulcanized modified asphalt layer, a tire base, an upper self-vulcanized modified asphalt layer and an upper surface anti-sticking layer from bottom to top; the raw material components of the lower self-vulcanization modified asphalt layer and the upper self-vulcanization modified asphalt layer both comprise vulcanization accelerators, and the content of the vulcanization accelerators in the lower self-vulcanization modified asphalt layer is smaller than that of the vulcanization accelerators in the upper self-vulcanization modified asphalt layer. According to the self-vulcanization modified asphalt waterproof coiled material disclosed by the invention, the production viscosity of the rubber material is reduced by adopting a self-vulcanization mode, the production temperature can be reduced by reducing the viscosity of the rubber material, and the production speed of the self-vulcanization modified asphalt waterproof coiled material is improved by virtue of the relatively low production temperature and viscosity of the rubber material, so the production energy consumption and pollution emission are reduced; through the differentiated self-vulcanization process, the better infiltration and creep properties of the lower surface to the base layer in the early vulcanization stage are met, and the vulcanization process of the upper surface is basically completed during construction.

Description

technical field [0001] The invention relates to the technical field of waterproof roll materials, in particular to a self-vulcanization modified asphalt waterproof roll material and a preparation method of the self-vulcanization modified bitumen waterproof roll material. Background technique [0002] At present, the modified bitumen waterproofing membrane is still the mainstream waterproofing material in China, with the largest market share. Mainly because of its high cost performance, through the selection of high-quality materials and scientific construction, the service life of more than 20 years can be achieved. However, the existing modified bitumen waterproofing membrane has been vulcanized during the production process, and the rubber material has a high viscosity. The energy consumption and pollution in the production process cannot meet the increasingly stringent environmental protection requirements in China. At the same time, hot-melt construction is also graduall...
