The invention provides water-based dry-sticking split leather transfer-film leather and a preparation method thereof.The preparation method comprises the steps that auxiliaries such as a water-based
wetting agent, a curing agent and a
thickening agent are added into water-based
polyurethane resin, a surface material, an intermediate material and a dry-sticking sticking material of the water-based
polyurethane resin are prepared through stirring, a
surface layer is firstly scraped on release paper through a dry-method transfer-film technology, then the
surface layer is scraped on the release paper through a dry-method transfer-film technology, and the dry-sticking sticking material is scraped on the release paper through a dry-method transfer-film technology; the water-based dry-sticking split leather transfer-film leather is prepared by the following steps of:
drying the release paper, scraping a middle layer after
drying, scraping a dry-sticking sticking layer after
drying, drying to be transparent at high temperature, sticking with split leather under the pressure of 3-5kg, attaching a PET (
Polyethylene Terephthalate) film, rolling, curing in a
greenhouse, and stripping the release paper and the PET film, thereby obtaining the water-based dry-sticking split leather transfer-film leather. The obtained water-based dry-sticking split leather transfer-film leather can be applied to the field of sneaker leather, is high in peel strength, resistant to bending at normal and low temperatures and resistant to
jungle hydrolysis, can improve the additional value of split leather, is comparable to first-layer leather, can effectively and uniformly permeate a dry-sticking layer according to the compaction degrees of different leather blanks, guarantees stable peel strength, and has a good application prospect. The method is suitable for large-scale
mass production.
