Abstract

The invention relates to the field of high polymer materials, and more particularly to the synthesis of hyperbranched epoxy resin and its application to asphalt waterproof rolls. Firstly, a hyperbranched epoxy resin is synthesized by using trimethylolpropane triglycidyl ether and dicarboxylic acid, and then the hyperbranched epoxy resin is applied to asphalt-based waterproof rolls. The product caneffectively improve the bonding performance of asphalt-based waterproof rolls.

Description

technical field [0001] The invention relates to the field of macromolecular materials, in particular to the synthesis of a hyperbranched epoxy resin and its application in asphalt waterproof rolls. Background technique [0002] At present, asphalt-based waterproofing membranes are divided into three types according to the construction method: hot-melt, self-adhesive and mechanical fixation. Hot-melt asphalt-based waterproofing membranes are widely used, with mature construction methods and firm and reliable bonding. However, heating is required during construction, which is easy to generate smoke and pollute the environment; and once it falls off from the base layer, it cannot be bonded again. The mechanically fixed asphalt waterproofing membrane cannot form full adhesion with the base layer, and once leakage occurs, it is difficult to maintain. Self-adhesive bitumen waterproofing membrane adopts cold bonding construction method, which is safe and reliable, and can form ful...
