Abstract

The invention provides a self-adhesive polymer modified asphalt waterproof coiled material and a preparation method and application thereof. The waterproof coiled material comprises the following rawmaterials in parts by weight: 35-40 parts of road petroleum asphalt, 10-15 parts of aromatic oil, 2-5 parts of a SBR modifier, 5-8 parts of SBS, 8-10 parts of activated rubber powder, 2-5 parts of ananticorrosive tackifier, 10-15 parts of tackifying resin, 3-5 parts of TPV resin and 15-20 parts of a filler. The peeling strength of the self-adhesive polymer modified asphalt waterproof coiled material with concrete and metals can be improved, the performance of the self-adhesive coiled material can be improved greatly, the self-adhesive polymer modified asphalt waterproof coiled material is convenient to construct, and can be used in occasions under corrosive environments, such as metal roofs exposed to outdoor, anticorrosive pipelines, underground waterproof and other projects.

Description

technical field [0001] The invention belongs to the technical field of waterproof rolls, and in particular relates to a self-adhesive polymer-modified bitumen waterproof roll and a preparation method and application thereof. Background technique [0002] In the prior art, self-adhesive polymer-modified bitumen waterproofing membranes are used in anti-corrosion and waterproof projects, because bitumen has poor acid and alkali resistance and poor adhesion to metal surfaces, so it is difficult to meet the needs of anti-corrosion projects. [0003] How to improve the acid and alkali resistance of the coil and provide the peel strength between the coil and the metal surface or the concrete surface has become an urgent technical problem to be solved. Therefore, it is necessary to provide a waterproof coil that can meet the relevant requirements. SUMMARY OF THE INVENTION [0004] In view of this, the present invention aims to provide a self-adhesive polymer-modified asphalt water...
