Problems solved by technology

In the prior art, the waterproof coiled material used for single-layer roofing is an exposed PVC waterproof coiled material. Since the PVC raw material in the PVC waterproof coiled material contains low molecular weight plasticizers, when exposed to sunlight, ozone, freeze-thaw When the natural conditions are destroyed, the plasticizer is easy to volatilize and migrate, which will cause cracks in the PVC coil and cause waterproof failure.

Abstract

The invention relates to the technical field of building materials, in particular to a PVC waterproof roll. The PVC waterproof roll is prepared from PVC resin particles, rubber particles, a plasticizer, an antioxidant, a stabilizer, a fire retardant and a light screening agent. In the technical scheme of the PVC waterproof roll disclosed by the invention, due to the fact that rubber has excellent ageing-resistant performance and higher heat resistance, the rubber is taken as a main material of modified PVC, and an ultraviolet light absorber, the light screening agent, the antioxidant and the like are added in the mixture of the rubber particles and the PVC particles, so that the outdoor ageing-resistant performance of the PVC waterproof roll is improved, and a double-protective effect is achieved with ethylene propylene rubber; and the PVC waterproof roll disclosed by the invention guarantees a physical performance index of the original PVC roll, the service life of the product is also prolonged, and the product life is more than 15 years. The PVC waterproof roll has the advantages of low production cost and good waterproof effect, the competitive advantages are obvious compared with similar products, and the PVC waterproof roll is suitable for being used in the field of architectural ornament.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a PVC waterproof coiled material. Background technique [0002] Roof leakage is a common problem in construction projects. To ensure the quality of waterproof projects, in addition to design and construction reasons, it is also necessary to select suitable waterproof materials. At present, there are many types of flexible waterproof materials on the market with different properties, such as petroleum, asphalt, and linoleum. However, when used as waterproof materials, they have problems of poor low-temperature flexibility, easy aging, and short service life. [0003] The polyester fiber internally reinforced polyvinyl chloride (PVC) waterproof membrane is a thermoplastic PVC membrane. The membrane uses polyester fabric as a reinforcing rib. Through a special extrusion coating process, the double-sided Polyvinyl chloride plastic layer and polyester reinforcing rib in th...
