Asphalt self-adhesive and high-polymer self-adhesion rubber waterproof coiled material prepared from asphalt self-adhesive

Abstract

The invention discloses asphalt self-adhesive. The asphalt self-adhesive comprises the following components in percentage by weight: 45 to 65 percent of asphalt, 16 to 25 percent of rubber oil, 5 to 15 percent of styrene butadiene styrene (SBS), 1 to 6 percent of styrene butadiene rubber (SBR), 1 to 6 percent of petroleum resin, 1 to 7 percent of ethylene vinyl acetate (EVA), and 10 to 20 percent of talcpowder. The invention also provides a high-polymer self-adhesion rubber waterproof coiled material which comprises a non-woven fabric coating, a high-polymer sheet coating, and an asphalt self-adhesive coating which consists of the asphalt self-adhesive from bottom to top. Two ends of the waterproof coiled material are provided with joint sides. The asphalt self-adhesive contains EVA, so the compatibility of the self-adhesive and a high-polymer sheet is improved, and compounding intensity of the high-polymer sheet coating is improved. The problem that the high-polymer sheets cannot be jointed reliably in a self-adhesion joint process is solved, so the coiled materials are jointed by the adhesive; and the coiled materials can be adhered firmly and reliably, and adjusted freely and flexibly.

Description

technical field [0001] The invention relates to a self-adhesive glue, and also relates to a polymer self-adhesive rubber waterproof roll material made of the self-adhesive glue, which can realize the adhesive glue overlapping mode. 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 constructi...

AI Technical Summary

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.
