Problems solved by technology

The products mainly include asphalt waterproof membrane and polymer waterproof membrane, but these types of waterproof membranes currently on the market will have heat resistance, weather resistance, ozone resistance, chemical corrosion resistance, and low temperature resistance in actual use. The flexibility and elastic-plastic properties are relatively weak, and the tear resistance is also relatively weak, so the service life is very short. Although it has so many weaknesses, due to the lack of technical knowledge of waterproof membranes at present, the optionality is very low.

Abstract

The invention provides a plastomer modified asphalt waterproof roll material. The plastomer modified asphalt waterproof roll material sequentially comprises an isolation layer, a plastomer modified asphalt coating, a blank base layer, a plastomer modified asphalt coating and an isolation layer, wherein the raw materials for preparing the plastomer modified asphalt coating include 100# petroleum asphalt, modified rubber powder, atactic polypropylene, a coupling agent and a filling agent. The plastomer modified asphalt waterproof roll material has strong low temperature resistance capability.

Description

technical field [0001] The invention belongs to the field of waterproofing, and more specifically relates to a plastomer modified asphalt waterproofing coiled material. Background technique [0002] Waterproof membrane is mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls, as an engineering basis The leak-free connection with the building is the first barrier for the waterproofing of the entire project and plays a vital role in the entire project. The products mainly include asphalt waterproof membrane and polymer waterproof membrane, but these types of waterproof membranes currently on the market will have heat resistance, weather resistance, ozone resistance, chemical corrosion resistance, and low temperature resistance in actual use. The flexibility and elastic-plastic properties are relatively weak, and the tear resistance is also ...
