| titleOfInvention | Multilayer condom containing modified polyurethane raw material and preparation method thereof |
| abstract | The invention provides a multilayer condom containing a modified polyurethane raw material and a preparation method thereof. The condom is of a multilayer sandwich type, and the preparation method comprises the following steps: (1) preparing an inner-layer adhesive film: reacting polyisocyanate with a chain extender to obtain fluorine-containing silicon-containing polyurethane emulsion, and then preparing a membrane; (2) preparing an intermediate layer adhesive film: prepared by blending polyisoprene rubber and modified polyurethane emulsion; (3) preparing an outer-layer adhesive film: the modified rosin resin latex is prepared by maleic rosin through emulsion polymerization, and then the modified rosin resin latex is blended with modified polyurethane emulsion and polyisoprene rubber emulsion to prepare a film; (4) and carrying out edge curling and demoulding forming to obtain a finished product. The multilayer condom obtained by the invention has no special smell and anaphylactic reaction, has high tensile strength, high elongation at break, good toughness and high resilience rate, has good bacteriostatic action on various common bacteria, has efficient barrier property on small molecules, can be well processed and produced, and has good application prospect. |
