Production method of wet-gas curing cold-resisting synthetic leather

The invention relates to a production method of wet-gas curing cold-resisting synthetic leather. The production method comprises the following steps: preparing materials in a dry method, smearing theprepared dry-method slurry on a release paper to form a surface material layer, and smearing a bottom material layer on the surface material layer; laminating the synthetic leather basic cloth and a bottom material, drying, obtaining a synthetic leather semi-finished product, cooling, stripping the release paper, obtaining synthetic leather, and rolling; and printing patterns on the prepared synthetic leather by virtue of a printing roller of a third-version printer, performing the color fixation, pressing grains, performing the wet-gas curing treatment by adopting a wet-gas curing machine, pre-drying by virtue of a drying box, drying the synthetic leather outputted from the drying box by virtue of a lamp tube, then stereotyping to obtain a finished product cold-resisting synthetic leather, and inspecting the fini
