Root penetrating-resistant waterproof coiled material for polyethylene copper ions

Abstract

The invention relates to the technical field of waterproof coiled materials, in particular to a root penetrating-resistant waterproof coiled material for polyethylene copper ions. The coiled materialhas both chemical root blocking function and mechanical root blocking function, can overcome defects of modified asphalt type root-resistant coiled materials and polymer type root-resistant coiled materials and ensures quality of planting projects. A production process of the coiled material comprises the following steps: (1) pretreatment; (2) preparation of polymer modified asphalt mulch; (3) inspection of polymer modified asphalt mulch; (4) forming; (5) finishing.

Description

technical field [0001] The invention relates to the technical field of waterproof coiled materials, in particular to a polyethylene copper ion root thorn resistant waterproof coiled material. Background technique [0002] As we all know, in the current root-resistant waterproofing membranes, whether it is modified asphalt or polymers, there is a problem of engineering leakage due to penetration by plant roots. Polymers such as PVC and TPO waterproofing membranes, in the construction process The welding seam is the biggest problem. If it is not handled well, the plant root system will penetrate at the welding seam; the seams of modified asphalt such as SBS waterproof membranes are constructed by hot-melt method, and the overlapping parts are firmly bonded, but this material It is completely relying on chemical root inhibitors to block roots. The amount of root inhibitors needs to be reasonably controlled. The addition of small amounts cannot achieve the effect of root resista...

[0002] As we all know, in the current root-resistant waterproofing membranes, whether it is modified asphalt or polymers, there is a problem of engineering leakage due to penetration by plant roots. Polymers such as PVC and TPO waterproofing membranes, in the construction process The welding seam is the biggest problem. If it is not handled well, the plant root system will penetrate at the welding seam; the seams of modified asphalt such as SBS waterproof membranes are constructed by hot-melt method, and the overlapping parts are firmly bonded, but this material It is completely relying on chemical root inhibitors to block roots. The amount of root inhibitors needs to be reasonably controlled. The addition of small amounts cannot achieve the effect of root resistance. Excessive additions will inhibit plant growth and cause plant death, and root inhibitors are not harmful. Any plant will work, e.g. Thinium, the bamboo-like rhizomes are so penetrating that chemical root retardants will have no effect on this plant
