Problems solved by technology

[0004] At present, single-layer roof waterproofing generally includes thermoplastic PVC, TPO membranes, thermosetting EPDM membranes and some high-performance modified bitumen membranes, but there is no successful case of using elastomer (SBS) modified bitumen waterproof membranes. The reason is that the elastomer (SBS) modified asphalt waterproofing membrane has some defects in high temperature resistance, aging resistance and construction convenience.

Abstract

The invention discloses a modified asphalt waterproof sheet material. The modified asphalt waterproof sheet material is of a multilayer structure; the upper surface of the modified asphalt waterproof sheet material is a mineral granule layer; a fiberglass reinforcement basic layer and a polyester reinforcement basic layer are sequentially arranged in the middle part of the modified asphalt waterproof sheet material in sequence; a self-adhesion polymer modification asphalt sizing material layer is arranged in the bottom layer of the modified asphalt waterproof sheet material; adjacent layers are adhered through an elastomer polymer modification asphalt sizing material layer; an isolation film is adhered on the self-adhesion polymer modification asphalt sizing material layer. The structure of the modified asphalt waterproof sheet material provided by the invention can be applicable to small deformation of the basic layers, and has the advantages of higher size stability, convenience in construction, adhesion reliability and self-heating property. The invention provides a reliable and exposed modified asphalt waterproof sheet material, and is particularly applicable to monolayer roofs.

Description

technical field [0001] The invention relates to a modified asphalt waterproof coiled material and belongs to the field of waterproof materials. Background technique [0002] Because the single-layer flexible roof system has the characteristics of light weight, good waterproof and thermal insulation performance, quick construction, easy maintenance, long life, and excellent long-term cost performance, it can completely solve the problems of water leakage, cold bridge condensation, noise, etc. of traditional roof systems. Due to the problem of multi-curved surface construction, the single-layer flexible roof system has become the most important roof system form of flat roof engineering in European and American countries. [0003] The single-layer roof system was officially introduced into China in 1999 and used in various projects. In view of its many significant advantages, the single-layer roof system has been quickly recognized and accepted by the domestic market and has b...
