复方TBZ防霉试验及在涂料中的应用

Studies on the Antimould Activity of Compound TBZ and its Application in Paint

复方ＴＢＺ是一种新的复合型防霉剂，主要成份为噻苯哒唑（Ｔｈｉ－ａｂｅｎｄａｚａｌ，简称ＴＢＺ）、乙酸、丙酸等。实验结果表明，其对１０株受试霉菌均具有良好的抗霉性能，抑菌圈≥６．０ｃｍ者占７０％，对从长霉墙壁上分离到的交链孢霉、芽枝霉等均具有明显的抑制作用。在实验条件下，经其涂刷的纤维板表面涂料１２０天不长霉，而直接涂料中添加同浓度ＴＢＺ的试验组，有２０％的表面是点状局限生长的霉菌。实际应用表明，将复方ＴＢＺ涂布在食品生产车间的墙上其防霉效果可保持２年以上。

The compound TBZ is a new antimould agent,which contains mainly [2 (4 thiazolyl)benzoimidazole(TBZ)],ethanoic acid and propionic acid.It was shown in laboratory experiment that the compound TBZ had excellent mycostatic effect on all the 10 fungi tested with 70% of the mycostatic zones larger than 6 0cm.It had obvious inhibitary activity on Alternaria Nees and Aureobasidium Pullulans isolated from mouldy wall.In laboratory condition the surface of fibreboard painted with compound TBZ did not become mouldy in 120 days,while the 20% of that coated with TBZ directly mixed in the paint became mouldy.In practical use,the antimould effect of the wall painted with compound TBZ could maintain more than two years.
