Abstract

The invention provides a preparation method of environment-friendly sofa leather used outdoors. The preparation method comprises the following steps: coating a water soluble adhesive or a hot melt adhesive on base cloth at temperature of 100-150 DEG C and carrying out drying treatment at temperature of 60-150 DEG C, thus preparing the base cloth; adding 0.05-0.2 parts by weight of colorant and 0.6-0.8 parts by weight of auxiliary to 0.6-1 part of thermoplastic elastomer, mixing the materials to be uniform, heating the mixture at temperature of 100-360 DEG C, compositing the mixture with the base cloth after melting, pressing the composite at 0.2-0.8MPa and then cooling the product; strengthening the prepared product in water at temperature of 30-80 DEG C and carrying out drying treatment, thus preparing the environment-friendly sofa leather used outdoors. The preparation method has the advantages that solvents are not used in the production process, so that the environment cannot be polluted; the adopted raw materials are environment-friendly and can be reused; the offcut can be reused; the problem of environmental pollution in the traditional synthetic leather production processes is solved and the requirements of outdoor products are met.
