POLYISOCYANATE HAVING DISPERSIBILITY AND LONG-LASTING MILDEWPROOFING FUNCTION, AND MILDEWPROOFING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a long-lasting mildewproofing material enabling a mildewproofing agent (benzimidazole or a benzimidazole derivative) to prevent fungi for a long period in the production process, and having improved solubility.

SOLUTION: The polyisocyanate having dispersibility and long-lasting mildewproofing functions, or the mildewproofing material has preferable interchangeability with a PU (polyurethane) material and enables the PU material to be easily dissolved or dispersed in different solvents because the mildewproofing agent (benzimidazole or a benzimidazole derivative) containing an NH amino group is added at the PU polymerization to make a part of a PU structure. The mildewproofing material reacts with a base material by using a silane reacting with a polyisocyanate and having a reactive functional group and a polyol to provide a bond and to provide characteristics of hardly causing flaking off, and is applied to an inorganic material such as a metal and a glass.
