Aqueous polyurethane dry process transform-film synthetic leather and manufacturing method thereof

The invention which relates to an aqueous polyurethane dry process transform-film synthetic leather and a manufacturing method thereof belongs to the technical field of synthetic leathers and manufacturing methods thereof. The manufacturing method of the aqueous polyurethane dry process transform-film synthetic leather is characterized in that the manufacturing method comprises the following steps: 1, preparing a base cloth which treats a non-woven fabric as the skeleton; 2, coating a superficial layer, a foaming layer and a bonding layer on release paper to realize the dry process transform-film; 3, carrying out leather-paper separation after the paper-leather separation or slaking; and 4, examining and warehousing. Compared with solvent-based polyurethane, the aqueous polyurethane dry process transform-film synthetic leather has equivalent physical properties, and accords with application demands, environmentally friendly aqueous polyurethane is used, a product (the aqueous polyurethane dry process transform-film synthetic leather) contains no organic solvents which are harmful to environmental protection, a DMF recovery operation which is required in the production process of solvent-based products is reduced, the production process is simplified, and energy saving and environmental protection are realized, so the aqueous polyurethane dry process transform-film synthetic leather which adapts to foreign restrictive requirements on environment friendly polyurethane synthetic leathers and allows the production personnel demand, the damage to the personnel, and the production cost to be reduced has a strong market competitiveness.
