Abstract

The invention discloses a rare earth complex containing leather composite coating agent which is prepared from the raw materials of polyurethane emulsion, oxidized polyethylene wax emulsion, fluorinecontaining acrylic emulsion, alkyl phenol polyoxyethylene ether, sodium dodecyl benzene sulfonate, octadecyl dimethyl (3-methoxy silicyl propyl) ammonium chloride, a diluent, rare earth complex, 1,4-bi(bromoacetoxy)-2-butene, silicone oil, N-allyl isothiazolinone and compound filler, wherein the compound filler is prepared by mixing nano iron oxide, nano titanium dioxide, oxidized graphene, a 5A zeolite molecular sieve, nano zirconium oxide and silane coupling agent KH-570. The rare earth complex containing leather composite coating agent disclosed by the invention has excellent antibacterialproperty, water resistance and ageing resistance; when the rare earth complex containing leather composite coating agent is applied to leather products, the antibacterial property, water resistance and ageing resistance of the leather products are remarkably improved; meanwhile, the prepared leather products have the advantages of good glossiness and soft and full hand feeling.

Description

technical field [0001] The invention relates to the technical field of leather, in particular to a leather composite finishing agent containing a rare earth complex. Background technique [0002] Currently used leather finishing agents mainly include polyurethane and acrylic resins. The antibacterial property of existing polyurethane finishing agents is not very good. During the process of wearing leather, microorganisms can multiply in large numbers, and their secretions can cause the biodegradation of polyurethane, resulting in mold spots and cracks on the fiber surface, seriously affecting the appearance of leather. The aesthetics, use effect and service life. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a leather composite coating agent containing a rare earth complex, which has excellent antibacterial properties, water resistance and aging resistance, and can be used in leathe...
