技術說明

抑制木材腐朽真菌之抗真菌組合物及其方法 本發明係利用沒食子酸衍生物(gallate acid derivatives)做為抑制木材腐朽菌之藥劑；本發明亦利用沒食子酸衍生物與肉桂醛(cinnamaldehyde)或丁香酚(eugenol)等化合物形成組成物做為抑制木材腐朽菌之藥劑。藥劑濃度配方為0.5~1000(μg/ml)。藥劑處理方法同一般木材防腐劑處理流程。本案技術可以解決傳統含金屬之木材防腐劑對環境生物之危害；本案技術亦可以解決新型含銅防腐劑無法有效抑制耐銅性木材腐朽菌之缺點，而且能有效抑制木材腐朽菌。 Gallate acid derivatives were used in this invention as antifungal agent against wood rot fungi. The combinations of gallate acid derivatives and cinnamaldehyde or eugenol or similar compounds were also used in this invention as antifungal agent against wood rot fungi. The methods for treating wood with chemicals are the same as general processes for wood preservatives treatments. The present invention can solve the environmental hazards problems derived from the traditional metal－containing wood preservatives. The present invention can also solve the problems derived from copper－containing wood preservatives nowadays which couldn’t inhibit copper tolerant fungi effectively.
