The invention discloses flame-retardant, heat-insulating, refrigerating, sun-proof and waterproof synthetic leather for tarpaulin and a preparation method thereof. The synthetic leather comprises a surface layer, a refrigerating layer, a heat reflecting layer, a middle layer and a matrix layer, wherein the surface layer has the functions of water resistance, sun screening and ultraviolet ray shielding, the refrigerating layer has the functions of heat insulation and refrigeration, the heat reflecting layer can reflect near infrared light in the wave band of sunlight to achieve the heat reflecting function, the middle layer can achieve the flame retardant effect, and the matrix layer has better flame retardance and sunlight reflecting capacity. The synthetic leather has multiple functions of flame retardance, heat insulation and refrigeration, sun protection and water resistance, and shares the functions of the sun protection function and the heat insulation function by using a multilayer structure, overcomes the defects of poor flame retardance, heat insulation, sun protection effect and the like of the existing tarpaulin, and has wide application field. The preparation method disclosed by the invention is low in energy consumption, easy to realize and beneficial to large-scale production of the flame-retardant, heat-insulating, refrigerating, sun-proof and waterproof synthetic leather for the tarpaulin. |
