Problems solved by technology

[0003] 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 waterproof rolling materials, and aims to provide an ethylene propylene rubber-modified PVC (Poly Vinyl Chloride) waterproof rolling material which is formed by modifying the ethylene propylene rubber. The waterproof rolling material is prepared from the following raw materials in parts by mass: 70 to 90 parts of PVC resin particles, 10 to 30 parts of ethylene propylene rubber particles, 0.2 to 0.5 part of ultraviolet absorbent, 0.1 to 0.2 part of antioxidant and 0.3 to 0.5 part of light screener. A preparation process of the ethylene propylene rubber-modified PVC waterproof rolling material comprises the following steps of: proportioning and mixing the PVC raw material and granulating; mixing the PVC particles with the ethylene propylene rubber particles and assistants together; and plasticizing, extruding, molding by cooling, and rolling. The waterproof rolling material has the beneficial effects of being strong in weather resistance, light in weight, easy to prepare, low in comprehensive cost, energy-saving and environmental-friendly; and the service life of the ethylene propylene rubber-modified PVC waterproof rolling material is prolonged.

Description

technical field [0001] The invention relates to the technical field of waterproof coiled material, in particular to an ethylene-propylene rubber modified PVC waterproof coiled material and a manufacturing process thereof. Background technique [0002] Polyvinyl chloride (PVC) waterproof membrane reinforced with polyester fiber is a thermoplastic PVC membrane, which uses polyester fiber fabric as reinforcement, through a special extrusion coating process, so Polyvinyl chloride plastic layer and polyester reinforcing rib in the middle are combined to form a polymer membrane. [0003] 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...
