Problems solved by technology

Most of the existing modified asphalt waterproofing membranes are only innovative in structure and function, and have not improved the construction performance of modified asphalt
However, the existing modified asphalt waterproofing membranes need to use natural gas, methane and other non-renewable fuels for hot-melt construction during construction, and the construction temperature often needs to be kept at 2000-3000 °C. This construction method consumes a large amount of fossil fuels, which will inevitably cause waste of resources

Abstract

The invention discloses a fusible high-performance elastomer modified asphalt waterproof roll. The fusible high-performance elastomer modified asphalt waterproof roll sequentially comprises a heat-sensitive fusible OPP (o-phenylphenol) isolating membrane, a fusible elastomer modified asphalt, a polyester reinforcement, fusible elastomer modified asphalt and a heat-sensitive fusible OPP isolating membrane from top to bottom. When the fusible high-performance elastomer modified asphalt waterproof roll is applied, the construction efficiency can be improved, the energy consumption is reduced, and the waterproof roll is energy-saving, environment-friendly and long in service life and has good economic benefits and social benefits. The experiment proves that the fusible high-performance elastomer modified asphalt waterproof roll disclosed by the invention has the advantage that the construction rate can be improved by 10-20 percent.

Description

technical field [0001] The invention relates to a modified asphalt waterproof coiled material, in particular to a fusible high-performance elastomer modified asphalt waterproof coiled material. Background technique [0002] Elastomer (SBS) modified asphalt waterproofing membrane is based on polyester felt or glass fiber felt, styrene-butadiene-styrene (SBS) copolymerized thermoplastic elastomer is used as modifier, and both sides are covered with polyester. Vinyl film, fine sand, powder or mineral granules (sheets) are used to make modified asphalt waterproofing membranes, which occupy an absolute dominant position in the European waterproofing material market. Except for Italy, other European countries mainly use SBS modification. , The market share is more than 80%, and it is used in various construction projects such as buildings, roads, railways, bridges, airports and subways. my country has introduced the production technology of modified asphalt waterproofing membrane...
