Abstract

The invention discloses a flame-retardant TPO (thermoplastic polyolefin) waterproof coiled material which is of a three-layer structure. The upper surface and the lower surface of the waterproof coiled material are flame-retardant TPO coiled material layers, a polyester fiber mesh grid fabric reinforced layer is arranged in the middle of the waterproof coiled material, the TPO coiled material layer of the upper surface is white, the flame-retardant TPO coiled material layer takes thermoplastic polyolefin synthetic resin materials combining ethylene propylene rubber and polypropylene as base materials and takes flame-retardant mixture as an auxiliary, safety of a product in the storage, transportation and use process is guaranteed, the weather resistance and the color retaining performanceof the product are guaranteed by cooperatively using anti-aging agents, anchoring agents, bridging agents, dispersing agents, softening agents and toners, so that the prepared waterproof coiled material is good in flame resistance, combustion performance level reaches non-combustible level, the waterproof coiled material has the advantages of high reflectivity, excellent energy-saving effect and pollution resistance. The flame-retardant mixture is mixture of dimethyl methylphosphonate and micro-encapsulation red phosphorus, and the weight ratio of the dimethyl methylphosphonate to the micro-encapsulation red phosphorus is 1:2.
