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.

Abstract

The invention relates to a coating composite material, in particular to a coating composite material with high heat insulation and high peeling strength taking polyvinyl chloride and polyester fiber base cloth as main base materials and a preparation method of the material, and belongs to the technical field of new materials. The composite material comprises a polyester fiber fabric base materiallayer, wherein a coating surface layer and a back layer are respectively arranged on both sides of the base material layer; the back layer comprises a flame-retardant PVC primer layer and a flame-retardant PVC heat insulation layer from inside to outside; and the coating surface layer comprises a flame-retardant PVC primer layer, a flame-retardant PVC heat insulation layer, a PVC high reflection layer and an infrared reflection heat insulation transparent layer from inside to outside, and is prepared by adopting a specific preparation method. The coating composite material has good heat insulation, high peeling strength and wicking resistance characteristics, and has excellent flame resistance, weather resistance and ultraviolet resistance.

Description

technical field [0001] The invention relates to a coating composite material, in particular to a coating composite material with high heat insulation and high peel strength and a preparation method thereof, which uses polyvinyl chloride and polyester fiber base cloth as the main base material, and belongs to new materials technology field. Background technique [0002] Polyvinyl chloride (PVC) coating composite material is a kind of film composite material obtained by coating polyvinyl chloride composite material on the surface of polyester fiber fabric or glass fiber fabric, and then plasticized at high temperature. , low cost and other advantages, it is widely used in membrane structure design (large stadiums, exhibition venues, airports, railway stations, plant sightseeing gardens, etc.), industrial fabrics (canopy fabrics, packaging fabrics), architectural sunshades (sunshades, curtains) and other fields. [0003] Membrane structure design is the main application field...
