Preparation method of antibacterial and mildew-proof TDI (toluene diisocyanate) memory polyurethane foam

The invention discloses a preparation method of antibacterial and mildew-proof TDI (toluene diisocyanate) memory polyurethane foam. The preparation method comprises the following steps of: 1) impregnating white mica powders in hydrogen peroxide to obtain expansion white mica powders after treatment; 2) adding the expansion white mica powders from the step 1 to trisodium phosphate solution to obtain a solid product after treatment; 3) adding the solid product from the step 2 to AgNO3 solution to obtain a solid-supported silver mica antibacterial agent after stirring and post-treatment; 4) adding the product from the previous step to the mixed solution of a diluting agent and a coupling agent for mixing, and then stirring to obtain a plastic antibacterial agent; and 5) adding the plastic antibacterial agent and a mildew-proof agent to a reaction kettle of butter PPG (Polypropylene Glycol) to realize dissolution by stirring, then adding a variety of accessories and TDI, stirring at high speed and then pouring the mixture into a reaction tank, and finally, naturally aging to obtain the product. According to the invention, the solid-supported silver mica antibacterial agent and the 8-hydroxyquinolinate mildew-proof agent are employed to result in antibacterial property and mildew-proof effect in the prepared product.
