The invention discloses
skin-friendly wear-resistant durable water-based
solvent-free
polyurethane synthetic leather for sofa home furnishing and a preparation method thereof. The synthetic leather comprises a water-based
surface layer, a water-based mechanical foaming middle layer, a
solvent-free composite bonding layer and a base cloth layer which are sequentially arranged from top to bottom. According to the water-based
surface layer, water-based anionic
polycarbonate polyurethane dispersoid and water-based
silicon PUD resin are compounded according to a certain proportion, excellent
weather resistance and good
skin-friendly touch feeling of a
silicon product can be obtained, the problem that the water-based
silicon PUD resin is bonded with a water-based
polyurethane interface after being coated and scraped to form a film is solved through the compounding formula, and the water-based
surface layer is formed. The problems of
delamination,
powder falling and the like of the silicon water-based
solvent-free polyurethane synthetic leather are solved, and the durability of the product is further improved. The water-based mechanical foaming middle layer obtained in a mechanical foaming mode has good rebound resilience and fullness after being dried to form a film. The prepared synthetic leather is high in
skin-friendly feeling and excellent in
wear resistance and durability.
