摘要
The present invention discloses a soluble or dispersible long-acting mold-proof polyisocyanate or modified polyurethane, and the mold-proof materials made thereof, wherein an amino group (NH)-containing mold-proof agent (benzimidazol or a derivative thereof) becomes a portion of a PU structure in a urethane or urea reaction; thus, the mold-proof material has the superior compatibility and solubility and can be solved or dispersed in various solvents. Further, the polyisocyanate reacts with a saline and a polyol both having reactive functional groups to implement the adhesion between the mold-proof material and the substrate; thus, the mold-proof material can be applied to an inorganic material, such as a metal or a glass. Therefore, the mold-proof material and the derivatives thereof of the present invention have a superior dispersibility/solubility and a long-acting mold-proof effect.
