Abstract

The invention provides a modified asphalt waterproof coiled material which comprises an upper surface layer, a modified asphalt layer, a core layer, fiberglass gridding cloth, a self-stick layer and an isolating membrane. The asphalt layer is prepared from the following raw material components: matrix asphalt, a modifying agent, softening oil, a reinforcing agent, regenerated epoxy resin powder, an inorganic filler and elastic granules. The self-stick layer is prepared from the following raw material components: matrix asphalt, a modifying agent, SBR rubber, SIS thermoplastic rubber, regenerated epoxy resin powder, elastic granules, rubber oil, tackifying resin and talcum powder. The waterproof coiled material provided by the invention is low in cost, less in energy consumption, good in mechanical performance and free of fire risk.

Description

technical field [0001] The invention discloses a formula, a structure and a construction process of a modified asphalt waterproof coiled material, and belongs to the technical field of waterproof coiled materials and the technical field of non-open flame construction of waterproof coiled materials. Background technique [0002] Asphalt membrane is currently recognized as a membrane with better waterproof performance; however, due to the characteristics of low-temperature brittleness, high-temperature flow resistance, and poor aging performance of raw asphalt, it needs to be improved through technology. The technical improvements for waterproofing mainly include catalytic oxidation asphalt and polymer modified asphalt. [0003] For example, the polyethylene tire modified asphalt waterproof membrane (0EE) in Woniushan Mountain in my country belongs to oxidation modification. The other is to add rubber or resin for modification. The added material can be rubber powder, SBS rub...
