High-performance synthetic rubber asphalt waterproof coiled material

Abstract

The invention relates to a high-performance synthetic rubber asphalt waterproof coiled material with good high and low temperature resistance, high bonding strength, good air permeability, high surface tensile strength and capability of meeting the long-term water leakage-proof use requirement in a 'composite waterproof system'. The coiled material consists of an upper coverage layer, a lower coverage layer and a middle waterproof layer, wherein the upper coverage layer is made of polyethylene polypropylene fibers, a polyethylene film or a metal aluminum foil; the lower coverage layer is made of needled polyester non-woven fabric; and the middle waterproof layer is made of modified asphalt glue layer prepared from modified asphalt glue. The performance of the coiled material is improved by organically and comprehensively utilizing special functional materials, multiple macromolecules and inorganic materials, the waterproof performance of the coiled material is greatly improved, the cost of the coiled material is effectively reduced, the service life of the coiled material is reliably guaranteed, and the coiled material used with non-curing glue can make a substantial contribution to construction of a complete composite waterproof system, so the coiled material has obvious technical advancement and strong practicability.

Description

technical field [0001] The invention relates to the technical field of building waterproof material manufacturing, in particular to a high-performance synthetic rubber asphalt waterproof coiled material suitable for use in composite waterproof systems and having a reliable water-proof effect. Background technique [0002] In recent years, with the rapid development of social economy and municipal construction, people have put forward high-level requirements for long-term waterproofing of buildings. For this, it has become one of the scientific research projects in various countries in the world. In the field of building waterproofing, rubber asphalt materials have always played a leading role because of their excellent waterproof performance. At present, the commonly used rubber asphalt waterproof material products mainly include synthetic rubber asphalt waterproof membranes and rubber modified asphalt waterproof coatings. The existing synthetic rubber asphalt waterproofing ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the poor long-term working reliability of the existing synthetic rubber asphalt waterproofing membrane, which is prone to bulging, peeling or cracking of the waterproof layer and water leakage at the joints during use. To meet the shortcomings of the "composite waterproof system" for medium and long-term use without water leakage, it provides a waterproof layer with good high and low temperature resistance, strong adhesion, high tensile strength, and is not easy to bulge and peel off the waterproof layer during use. High-performance synthetic rubber asphalt waterproofing membrane that can meet the medium and long-term water-tight use requirements of the "composite waterproofing system"
