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...
