Problems solved by technology

[0003] The polymer waterproof membrane currently on the market includes the following three categories: 1. Polyvinyl chloride (PVC) waterproof membrane: it has the advantages of high strength, excellent tensile properties, and good high and low temperature resistance. Plasticizer, long-term exposure, the plasticizer will migrate, resulting in the loss of flexibility, ductility and even fracture of the coil; and the additive contains chlorides, which will produce toxic volatile gases during construction and use, endangering human health; 2. Thermoplastic Polyolefin (TPO) waterproof membrane: it has excellent aging resistance and weather resistance, and can be exposed to specific harsh environmental conditions for a long time; the composition does not contain chlorinated polymers or chlorine, and it is healthier and more environmentally friendly than PVC in specific environments , but its tensile properties and tear strength are not as good as PVC, and its adaptability to different geological environments is not strong; 3. High-density polyethylene (HDPE) waterproof membrane: has good heat resistance and cold resistance, chemical stability Good resistance, high rigidity and toughness, good mechanical strength, but poor aging resistance and environmental cracking resistance, especially thermal oxidation will reduce its performance

Abstract

The invention discloses a polymer waterproof roll and a production process thereof. The waterproof roll comprises an outer waterproof layer, a base material layer, an isolating membrane layer and an inner polymer polyester layer which are in press fit from outside to inside, wherein the outer waterproof layer and the base material layer are composited by a pressure-sensitive adhesive, and the isolating membrane layer and the inner polymer polyester layer are composited by the pressure-sensitive adhesive. The production process comprises five steps as follows: material blending and internal mixing; extrusion; three-roller calendering; cooling forming; cutting and rolling. The waterproof roll has good waterproof and dampproof performance, weather resistance, aging resistance, wear resistanceand tensile property and can meet the demand of most building fields for waterproof and dampproof performance.
