The invention relates to a molecular sieve-based antibacterial additive for automobile leather and a preparation method and application thereof. The preparation method includes the following steps: after mixing silver salt and 13X molecular sieve material, adding a reducing agent solution, and reacting to obtain the molecular sieve-based antibacterial additive for automobile leather. The antibacterial agent makes the dispersing effect of the effective substance silver better, has good compatibility with the production system of polyurethane raw material for automobile leather, and improves the mechanical strength of the automobile leather material; the nano-silver element is dispersed on the surface of the carrier 13X molecular sieve, and there is no silver element. agglomeration phenomenon. The molecular sieve-based antibacterial additive involved in the invention can solve the application problem of the nano-silver bactericide in automobile leather products, and can be used as the antibacterial additive of the polyurethane synthetic leather for automobiles. |
