Description

technical field [0001] The invention belongs to the technical field of preparation of modified bitumen waterproofing membranes, and particularly relates to a novel root-resistant puncture modified bitumen waterproofing membrane and a preparation method thereof. Background technique [0002] Waterproofing membrane is mainly used in building walls, roofs, tunnels, highways, landfills, etc. It is a flexible building material product that can be rolled into rolls to resist external rainwater and groundwater leakage. As a leak-free connection between the engineering foundation and the building, the waterproofing membrane is the first barrier of the entire engineering waterproofing and plays a vital role in the entire engineering. In the prior art, the waterproofing membrane still has problems such as insufficient high and low temperature performance, insufficient durability, and poor root puncture resistance. Before reaching the standard service life of the membrane, it has alrea...

Problems solved by technology

Although the waste waterproofing membrane is reused, the heating temperature is too high during the construction process, which will generate higher energy consumption and pollute the environment

[0005] CN201811608484.2 discloses an anti-oxidation polymer composite waterproof membrane and a laying method of the composite waterproof membrane. From top to bottom, it consists of a modified asphalt waterproof membrane layer, a butyl rubber waterproof membrane layer, a poly The vinyl chloride waterproofing membrane layer, hot melt adhesive layer and isolation membrane layer are compounded, the construction process is complex, and the bonding effect between the layers cannot be guaranteed, and the bonding part is the weak link of the waterproofing membrane

[0006] At present, the waterproof membranes on the market are mainly focused on waterproof performance, and the existing root puncture-resistant waterproof membranes still have the following defects in the preparation: not only poor water resistance, low tensile strength, and wind resistance, self-healing Weak performance means that the anti-rooting period and service life are short, and the anti-rooting period and service life are seriously shortened after heat aging
