The invention discloses synthetic leather for
flame retardant, insulating, cooling, sun protecting and waterproof tarpaulins and a preparation method of the synthetic leather. The synthetic leather comprises a
surface layer, a cooling layer, a heat-reflecting layer, an intermediate layer and a matrix layer, the
surface layer has the function of
waterproofing, sun protecting and
ultraviolet light shielding, the cooling layer has the function of heat insulation and cooling, the heat-reflecting layer can reflect the
near infrared light in the band of
solar light to achieve heat reflection, the effect of
flame retardancy can be realized in the intermediate layer, and the matrix layer has good
flame retardancy and the capacity to reflect
sunlight. The synthetic leather has the multiple functions including flame retardancy, heat insulation and cooling, sun protecting and
waterproofing, the sun protecting and heat insulation functions are shared by a multi-layer structure, shortcomings and defects of poor effect of flame retardancy, heat insulation,
sun protection and the like of existing tarpaulins are overcome, and wide application field is achieved; the preparation method has the advantages of low
energy consumption and easy realization, and is beneficial to large-scale production of the synthetic leather for the flame retardant, insulating, cooling, sun protecting and waterproof tarpaulins.
