Problems solved by technology

[0003] The asphalt layer in the above known self-adhesive rubber asphalt waterproofing membrane is self-adhesive rubber asphalt, which has poor high temperature resistance, generally only has a high temperature resistance of 70°C. In occasions that require high temperature resistance, such as metal roofs, high temperature resistance is required. 110℃ membrane, the existing high heat-resistant self-adhesive rubber asphalt waterproof membrane cannot be applied

Abstract

The invention provides a high heat-resistant self-adhesive rubber asphalt waterproof membrane, the modified asphalt layer contains mineral powder and more than two kinds of tackifiers, does not flow at high temperature (110°C), and has a peel strength of 0.8N / mm or more, it has good adhesive performance.

Description

technical field [0001] The invention relates to a self-adhesive waterproof coiled material, in particular to a high heat-resistant self-adhesive rubber asphalt waterproof coiled material. Background technique [0002] At present, the known self-adhesive construction method rubber asphalt waterproofing membrane is based on elastomer modified asphalt such as SBS, and the tough waterproof polyethylene film or aluminum foil is used as the upper surface material of the membrane or without membrane (double-sided self-adhesive). It is a tireless self-adhesive waterproof membrane made of peelable silicon-coated film or silicon-coated crepe paper as the material of the lower surface anti-adhesive isolation layer. The product implements the national industry standard of JC 840-1999 "High heat-resistant self-adhesive rubber asphalt waterproof membrane". [0003] The asphalt layer in the above known self-adhesive rubber asphalt waterproofing membrane is self-adhesive rubber asphalt, wh...
