Abstract

The invention provides an environment-friendly root-puncture-resistant PVC waterproof coiled material and a preparation method thereof.The waterproof coiled material comprises a PVC sheet layer and elastomer film layers compounded on the upper surface and the lower surface of the PVC sheet layer, and each elastomer film layer comprises, by weight, 100 parts of ethylene-propylene elastomer resin, 1-5 parts of filler and 0.3-0.7 part of chemical root-resistant agent. The waterproof coiled material disclosed by the invention does not contain phthalate and lead salt, and is more environment-friendly; the coiled material is very low in water absorption rate, high in joint peeling strength, firm and durable in weld joint, excellent in mold corrosion resistance and root puncture resistance, and suitable for construction application of underground waterproof layers with planting and greening requirements.

Description

technical field [0001] The invention relates to the technical field of waterproof coiled material, in particular to an environment-friendly root puncture-resistant PVC waterproof coiled material and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) waterproof membrane is based on polyvinyl chloride resin, adding a certain amount of plasticizers, anti-aging agents, heat stabilizers, ultraviolet absorbers, lubricants, fillers and other processing aids, A polymer waterproof membrane that has been extruded once. At present, phthalate plasticizers are the main plasticizers of polyvinyl chloride waterproof membranes, and such plasticizers are mainly dioctyl phthalate (DOP), dibutyl phthalate ( DBP), diheptyl phthalate (DHP), diisodecyl phthalate (DIDP), diisooctyl phthalate (DIOP), etc. At the same time, lead salt heat stabilizers are usually used in the formulation system of PVC coils. Now it is generally recognized that the plasticizer in th...
