The present invention discloses an easy-decontamination and high-wear-resistance synthetic leather for sofas and a preparation method thereof. The easy-decontamination and high-wear-resistance synthetic leather for sofas is prepared by coating an antifouling and wear-resistant slurry on the surface of a polyurethane synthetic leather base for sofas. The polyurethane synthetic leather base for sofas is formed by compounding a polyurethane film with a base fabric, and the polyurethane film is extruded from a polyurethane slurry through a T-type casting die. The polyurethane slurry comprises the following raw materials by weight: 60 to 90 parts of waterborne polyurethane, 30 to 45 parts of N,N-dimethylformamide, 5 to 10 parts of ultrafine lignin, and 10 to 28 parts of nano calcium carbonate. The synthetic leather prepared by the present invention has the style and appearance of natural leather, is soft in hand feeling, and has high wear resistance and air permeability. The antifouling and wear-resistant slurry coated on the surface of the synthetic leather base makes the surface of the synthetic leather product easy to clean and resistant to stains. The slurry has high adhesion to the synthetic leather base, excellent wear resistance, and long service life.
