Flame-retardant polyester fiber internally-enhanced PVC waterproof coiled material, preparation method and system

The invention belongs to the technical field of waterproof coiled material preparation, and discloses a flame-retardant polyester fiber internally-enhanced PVC waterproof coiled material, a preparation method and a system. The flame-retardant polyester fiber internally-enhanced PVC waterproof coiled material is prepared from the following components in parts by mass: 10-20 parts of PVC resin powder, 3-7 parts of nano flame-retardant particles, 4-9 parts of kaolin, 3-4 parts of nano aluminum hydroxide, 1-3 parts of an antioxidant, 1-2 parts of a light stabilizer, 2-3 parts of a surfactant, 4-8 parts of talcum powder and 10-20 parts of polyester fibers. According to the flame-retardant polyester fiber internally-enhanced PVC waterproof roll, the middle layer is the flame-retardant polyester fiber fabric, the outer layer is coated with the PVC layer, and the fireproof and flame-retardant effects can be improved; and in the preparation of the PVC layer, materials with a good flame-retardant effect, such as an ant
