Problems solved by technology

This kind of manufacturing process makes the self-adhesive adhesive and the subject material layer bond firmly, and it cannot be peeled off by artificial methods
However, the waterproof coiled material provided by the present invention does not reserve overlapping edges, and the cement slurry is easy to pollute the overlapping parts during the construction process, causing the overlapping joints to be not dense.

Abstract

The invention provides an asphalt self-adhesive, and a preparation method and a use thereof. The asphalt self-adhesive comprises, by weight, 70-75 parts of asphalt, 10-15 parts of rubber oil, 13-15 parts of SBS, 5-10 parts of polyamide resin, 10-15 parts of N,N-dimethylformamide and 5-10 parts of triethylvinylsilane. The asphalt self-adhesive is modified, modifiers are added, and the use amount proportions are optimized, so the bonding strength of the asphalt self-adhesive is improved, and the high-temperature resistance and the cohesive force of the asphalt self-adhesive are improved.

Description

technical field [0001] The invention belongs to the technical field of modified asphalt, and in particular relates to an asphalt self-adhesive used in waterproof coiled materials, a preparation method and application thereof. Background technique [0002] At present, my country's waterproof membranes include asphalt-based membranes and polymer membranes. The construction methods of asphalt-based membranes include: wet laying, pre-laying, self-adhesive, hot-melt and empty laying, and the construction methods of polymer membranes include: empty laying, mechanical fixing and gluing. The overlapping methods of asphalt-based coils include: self-adhesive, hot-melt, and the overlapping methods of polymer coils include: hot-melt welding and adhesive bonding. [0003] The hot-melt construction method is more common; the use of empty paving is relatively rare, and it is mainly suitable for engineering projects with a relatively low waterproof level; the self-adhesive construction met...
