Embodiment Construction

[0016] Octopine, CAS No.: 34522-32-2, is available from Shanghai Jinjinle Industrial Co., Ltd.

[0017] For the preparation method of the compound Daphenylline involved in the present invention, please refer to the literature: (Daphenylline, a NewAlkaloid with an Unusual Skeleton, from Daphniphyllum longeracemosum, Org. Lett., 2009, 11(11), 2357-2359).

[0018] Effect test:

[0019] The test material willow, produced in Jiangsu Province, is 5-10 years old and has no defects. Peel the bark and process it into finely planed willow sticks, and air-dry in the natural environment to a moisture content of 12% to 15%. In this experiment, all willow wood was processed into 40mm×30mm×6mm (length×width×thickness) samples.

[0020] Mold: Aspergillus nigerV.Tiegh (Aspergillus nigerV.Tiegh), Penicillium citrintimThom (PenicilliumcitrintimThom), bacterial classification is provided by Institute of Wood Industry, Chinese Academy of Forestry Sciences.

Abstract

The invention discloses a wood preservative containing a compound Daphenylline. The ratio Daphenylline to octopine in of parts by weight is (1 to 1 ) to (30 to 1). According to the wood preservative disclosed by the invention, good wood anti-mildew effects are obtained by mixing the Daphenylline with the octopine in a specific ratio; and especially when the ratio of the Diphenylline to the octopine in parts by weight is (22 to 1) to ( 26 to 1), and synergistic anti-mildew effects are very obvious.

Description

technical field [0001] The invention relates to a preservative, in particular to a wood preservative containing the compound Daphenylline, and belongs to the technical field of agriculture. Background technique [0002] So far, the most commonly used method to prevent wood decay is to use chemical antiseptics. Leakage and seepage of preservatives during production and use, as well as waste and burning of preservative treated wood will have adverse effects on the environment and endanger human health. healthy. As environmental issues are getting more and more attention, it has also become the key to choosing preservatives. [0003] Water-soluble preservatives are currently the most used, accounting for about 3 / 4 of the total amount of preservatives used. Since the range of a single preservative against wood rot fungi and insects is relatively narrow, two or more preservatives are generally mixed in a certain proportion, which can not only overcome the shortcomings of a sing...
