The invention discloses a reflective heat-insulation PVC waterproof coiled material and a preparation method thereof. The coating comprises the following components in parts by weight: 100 parts of PVC resin powder; 20-60 parts of a plasticizer; 10-30 parts of a toughening agent; 4-6 parts of epoxidized soybean oil; 2-5 parts of a heat stabilizer; 3-12 parts of potassium hexatitanate and/or sodium hexatitanate; 3-5 parts of titanium dioxide; 0.2-0.5 part of stearic acid; 0.1-0.4 part of calcium stearate; 0.2-2 parts of an antioxidant; 0.2-2 parts of a light stabilizer; 20-40 parts of calcium carbonate; 0.1-0.5 part of coupling agent. The coiled material has excellent dimensional stability, reflection and heat insulation performance, better mechanical property, low-temperature toughness and ageing resistance, long service life, energy conservation and environmental protection, and is particularly suitable for being used by exposed roofs. |
