Embodiment 1

[0058]Example 1, Example 2, and Comparative Examples 1 to 6 The preparation method of the waterproof coiled material samples is as follows: the upper and lower surfaces of the base layer are uniformly coated with modified asphalt to obtain a three-layer structure, and then in the three-layer structure The upper and lower surfaces are covered with isolation layers to obtain a waterproof membrane;

[0059] Wherein, the preparation method of the modified asphalt is as follows: adding the mixed asphalt into the reactor, controlling the temperature of the reactor at 170° C., starting the stirring, and slowly adding the stabilizer, thermoplastic polyurethane resin, SBS resin, tackifying resin, (3, 3-dimethylbutyl) triethoxysilane, after being stirred uniformly, the material is discharged to obtain the modified asphalt.

[0060] The types and amounts of raw materials used to prepare modified asphalt in Example 1, Example 2, and Comparative Examples 1-6 are listed in Table 2, in terms...

Abstract

The invention provides a self-adhesive polymer modified asphalt waterproof coiled material, specially-made thermoplastic polyurethane resin is added into the asphalt layer raw material of the waterproof coiled material, the thermoplastic polyurethane resin has good compatibility with other components, and the waterproof performance and the mechanical performance of the waterproof coiled material can be improved when the thermoplastic polyurethane resin matches the other components for use. The invention further provides a preparation method of the waterproof coiled material.

Description

technical field [0001] The invention relates to a self-adhesive polymer modified asphalt waterproof roll material and a preparation method of the waterproof roll material. Background technique [0002] Waterproof roll material is mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage. It is a flexible building material product that can be rolled into rolls. The first barrier of engineering waterproofing plays a vital role in the entire project. At present, the common waterproofing membranes on the market are mainly asphalt waterproofing membranes, but this kind of waterproofing membranes has problems such as insufficient peel strength and insufficient waterproof performance. [0003] Therefore, in order to solve the problems existing in the prior art, it is necessary to provide a waterproof coiled material with excellent waterproof performance and excellent mechanical properties.
