COLORING PREVENTIVE AGENT OF LUMBER, MILDEWPROOF COMPOSITE FOR LUMBER AND MILDEWPROOF METHOD OF LUMBER

摘要

PROBLEM TO BE SOLVED: To prevent the coloring of lumber due to an iron component by containing multivalent alcohol fatty acid ester as an effective component. ;SOLUTION: Only multivalent alcohol fatty acid ester is used as an effective component for preventing the coloring of lumber caused by an iron component. Allowing a small quantity of tolyltrirazole to coexist with multivalent alcohol fatty acid ester can enhance much a preventive effect of the coloring of lumber due to an iron component. The using density of multivalent alcohol fatty acid ester is preferable to be usually about 200 ppm or more relative to the mildew prevention treatment liquid of lumber. For multivalent alcohol fatty acid ester, there is each given, e.g. glycerol monoarate, pentaerythritol monopalmitart, sorbitan monolaurate, sorbitan monostearate, and monoester such as sucross monostearate, and these diester and triester as well.;COPYRIGHT: (C)1998,JPO
