Zusammenfassung:PROBLEM TO BE SOLVED: To provide a method for simply and easily producing a polyurethane foam which causes no problems in production and physical properties such as reaction delay and coloration even if an antibacterial agent containing a silver compound is added to a polyurethane foam raw material and exhibits bactericidal properties based on the antibacterial spectrum of a silver compound.SOLUTION: There is provided a method for producing an antibacterial polyurethane foam which comprises a step of reacting a raw material containing a polyol, an organic isocyanate, a catalyst, a foaming agent and an antibacterial agent, in which the antibacterial agent contains a silver compound having water solubility at 25°C of 0.01 to 0.8 g in 100 g of a saturated aqueous solution in terms of silver atoms.SELECTED DRAWING: None 【課題】ポリウレタンフォーム原料へ銀化合物を含有する抗菌剤を添加しても、反応遅延、着色等の製造上及び物性上の問題を発生せず、しかも、銀化合物の抗菌スペクトルに基づく抗菌性を発揮するポリウレタンフォームを簡易かつ簡便に製造する方法を提供する。【解決手段】本発明の抗菌性ポリウレタンフォームの製造方法は、ポリオール、有機イソシアネート、触媒、発泡剤、及び抗菌剤を含む原料で反応させる工程を含み、前記抗菌剤は、25℃の水溶解度が銀原子換算で飽和水溶液100g中0.01〜0.8gである銀化合物を含むことを特徴とする。【選択図】なし
