Embodiment 1
[0074] S1: Select the gram weight as 260g / m 2 1. The substrate layer is made of plain weave structure polyester fabric with polyester fiber linear density of 1000dtex;
[0075] S2: First weigh the following raw materials in parts by weight: 100 parts of PVC paste resin, 3.5 parts of liquid calcium-zinc composite stabilizer, 40 parts of plasticizer, 35 parts of flame-retardant plasticizer, 4 parts of decabromodiphenylethane, three 4 parts of antimony oxide, 3.2 parts of zinc borate, 2 parts of zinc hydroxystannate, 7 parts of vinyl chloride-vinyl acetate copolymer resin, stir well, then grind twice on the three-roller mill, add 8 parts of bonding agent while stirring agent, 2 parts of cross-linking agent, 8 parts of cross-linking aid and 12 parts of viscosity reducer, and finally stirred at high speed for 30 minutes to obtain a flame-retardant PVC primer paste slurry, which was dipped and rolled by rubber wheels. Under tension traction, evenly coat the flame retardant PVC base...
Embodiment 2
[0081] The only difference with Example 1 is that the raw materials of the flame-retardant PVC primer layer in Example 2 are: 100 parts of PVC paste resin, 3.5 parts of liquid calcium-zinc composite stabilizer, 40 parts of plasticizer, and 35 parts of flame-retardant plasticizer , 3 parts of decabromodiphenylethane, 3 parts of antimony trioxide, 2.4 parts of zinc borate, 1.5 parts of zinc hydroxystannate, 5 parts of vinyl chloride-vinyl acetate copolymer resin, 8 parts of binder, 2 parts of crosslinking agent , 8 parts of cross-linking auxiliary agent, 10 parts of viscosity reducer.
Embodiment 3
[0083] The only difference from Example 1 is that the raw materials of the flame-retardant PVC primer layer in Example 3 are: 100 parts of PVC paste resin, 3.5 parts of liquid calcium-zinc composite stabilizer, 40 parts of plasticizer, and 35 parts of flame-retardant plasticizer , 4 parts of decabromodiphenylethane, 4 parts of antimony trioxide, 3.2 parts of zinc borate, 2 parts of zinc hydroxystannate, 5 parts of vinyl chloride-vinyl acetate copolymer resin, 5 parts of binder, 1.5 parts of crosslinking agent , 6 parts of cross-linking auxiliary agent, 7 parts of viscosity reducer.
