The invention provides a sterilizing agent and a preparation method thereof. The sterilizing agent comprises alkyl glycoside, modified glycoside, ethanol, iodine, potassium iodide, potassium iodate and water. The preparation method comprises the following steps: mixing, dissolving, complexing and adding additives. The preparation method is characterized in that a carrier subjected to complexation with iodide is a non-toxic non-irritating green environment-friendly product, has sterilization performance and can form a stable complex with the iodide, a final complex has the characteristic of thickening after being diluted and has the performances of green environmental protection and multiple sterilization, the preparation method is simple, the prepared product has good usability, good solubility, good stability, thickening after dilution and the like, and the preparation method is simple in technological process, easy to control, short in production cycle, low in production cost and suitable for industrial production.

Sterilizing agent and preparation method thereof

The invention provides a cationic polyurethane-polyurea water dispersion, and a preparation method and application thereof. The dispersion is mainly prepared from the following raw materials: a) at least one polyamine containing tertiary amino groups, wherein the polyamine containing the tertiary amino groups at least contains two functional groups with reactivity with -NCO, and the functional groups are selected from primary amino groups and/or secondary amino groups; b) at least one polyhydric alcohol with functionality of 2-4 and with a number-average molecular weight of from 500 g/mol to 15000 g/mol; c) at least one polyisocyanate component; d) at least one nonionic polyhydric alcohol which is different from the component b) and has a number-average molecular weight of from 500 g/mol to 10000 g/mol; e) at least one neutralizer; and optionally other components. The invention provides the cationic polyurethane-polyurea water dispersion which is simple to operate and easy to control and has improved film-forming performance, heat resistance and yellowing resistance.

Cationic polyurethane-polyurea water dispersion, and preparation method and application thereof

The disinfecting detergent is made of polyoxyethylene alcohol ether, iodine, potassium iodide, potassium iodate, and deionized water or distilled water. It is possible to add polyethylene pyrrolidone and beta-cyclic amylin, and features greatly-increased stability, efficient broad-spectrum disinfecting action and high cleaning effect.
