| 摘要 |
The present invention discloses an antimicrobial polyisocyanate and derivatives thereof, wherein a quaternary amine is added into the polymerization reaction of a polyol and a NCO-containing isocyanate/poly-isocyanate to form the antimicrobial polyisocyanate; then, the antimicrobial polyisocyanate is added into a functional resin to form an antiseptic material. As the bactericide (the quaternary amine) becomes an inseparable portion of the polyisocyanate and the antiseptic material containing the poly-isocyanic ester, the bactericide will be uniformly distributed on the surface of material; further, the bactericide will not be released out but will be maintained permanently. Such a mechanical-contact type antiseptic method can achieve a safe, persistent and environment-friendly antiseptic effect.
