Abstract

The invention provides an antibacterial and mildew-resistant superfine-fiber synthetic leather, a preparation method and products thereof. The antibacterial and mildew-resistant superfine-fiber synthetic leather comprises polyurethane resin and a composite antibacterial agent uniformly dispersed in the polyurethane. The preparation method comprises adding a foaming agent, a foam stabilizer, water and an aqueous coloring agent into an aqueous anionic polyurethane impregnated slurry, uniformly stirring by using a high-speed mixer to prepare into slurry, fully wetting and dispersing an inorganic antiseptic, an organic antiseptic, a compatibility treating agent and an anti-discoloration agent in dimethylformamide, stirring, grinding, adding the composite antibacterial agent with an adjusted viscosity into polyurethane synthetic leather molding slurry, uniformly mixing, and molding. The antibacterial and mildew-resistant superfine-fiber synthetic leather can be widely applied in shoes, sofa, clothes leather, case leather and leather for furniture and interior decoration.

Description

technical field [0001] The invention relates to a method for manufacturing superfine fiber synthetic leather, in particular to a method for preparing antimicrobial and mildew-proof superfine fiber synthetic leather. Background technique [0002] At present, polyurethane synthetic leather has been used in various fields of people's life, and there are various varieties. Among them, the high-grade microfiber synthetic leather has developed rapidly in recent years due to its advantages in physical properties and the appearance of imitation leather. The traditional wet production process of superfine fiber synthetic leather is to impregnate non-woven fabric with solvent-based polyurethane as the impregnating slurry, then solidify in DMF (dimethylformamide) aqueous solution, extract it from a hot toluene tank, wash and dry, Among them, a large amount of DMF and toluene are used, and the solvents that cannot be fully recovered are discharged in the form of gas and waste water, pol...
