Benefits of technology

The technical effect of this patented technology is that it allows manufacturers to make strong adherents on their own without requiring expensive equipment or complicated processes like lamination with other materials. This makes them more efficient than traditional methods such as spray coating.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the strength between different materials used together during building constructions without causing separation over time due to poor anchoring caused by moisture buildup (frost).

Abstract

The invention discloses a self-adhesive waterproof coiled material having high initial stickiness. The coiled material comprises the following components, by mass: 35%-55% of petroleum asphalt, 5%-25% of a softening agent, 5%-25% of a modifying agent, 2%-8% of a tackifier, 0.1%-2% of an interface agent, 0.1%-3% of an anti-aging agent, and 5%-20% of a filling agent. The self-adhesive waterproof coiled material has excellent initial stickiness, even under conditions of a basement layer surface with a little dust, a damp basement layer and a relatively low temperature, the coiled material also has good adhesion with the basement layer, and is not easy to strip after adhesion; after stripping, the coiled material can ensure to leave an integral modified asphalt material on the basement layer, so as to ensure relatively high waterproof performance.
