Abstract

The invention discloses a PVC (polyvinyl chloride) waterproof coiled material. The PVC waterproof coiled material is characterized in that: boric sludge or red mud serving as a filling material is added into raw materials of the PVC waterproof coiled material, and the mass percent of the adding amount of the boric sludge or the red mud in the raw materials of the PVC waterproof coiled material to the adding amount of PVC resin is 40-50: 100. The PVC waterproof coiled material has the advantages of flame resistance, corrosion resistance and color exposure; the boric sludge or the red mud serving as the filling material in the PVC waterproof coiled material remarkably improves the use stability and ageing resistance of the PVC waterproof coiled material, and increases the functions of corrosion resistance, fire resistance, self cleaning and the like. A preparation process for the PVC waterproof coiled material is simple, and the boric sludge or the red mud used as the common filling material only needs to be blended.

Description

technical field [0001] The invention belongs to the technology of polymer waterproof coiled material, and in particular relates to a PVC waterproof coiled material with good flame-retardant, anti-corrosion and anti-aging properties and a preparation process thereof. Background technique [0002] With its excellent mechanical properties and convenient construction methods, PVC waterproof membrane has won a wide market in industrial and civil construction waterproofing, especially in the application of exposed waterproofing and anti-root puncture waterproofing layers of planted roofs. However, due to the poor thermal stability of PVC resin and the insufficient stability of the pigment body, the exposed PVC waterproof layer is prone to aging and fading, and the aging speed is also fast, which cannot meet the requirements of exposed roof waterproofing, underground building waterproofing, municipal engineering waterproofing and other reasons. Planting roof anti-root thorn waterpr...
