Abstract
The invention relates to a waterborne hinokitiol wood preservative and a preparation method thereof, and is used for solving the problems that hinokitiol giving a natural corrosion resistance to wood has poor water solubility and is difficult to use. The wood preservative comprises the components according to mol ratio: 0.2-2 mol of hinokitiol, 1 mol of a solubility promoter, and 0.01-1 mol of a tannin extract (the molar ratio calculated according to the content of phenolic hydroxyl group). The wood preservative is used for processing the wood, and when the mass concentration of hinokitiol is about 1%, the resistance of the processed wood to Aspergillus niger, Penicillium citrinum, Trichoderma is up to 100%, and the fungal growth is completely inhibited; and moreover, the molding resistance of the processed wood to Coriolus versicolor and Gloeophyllum trabeum can achieve strong molding resistance level.
Description
Technical field
The present invention relates to a kind of water ballast type plant resource wood preservative and preparation method thereof.
Background technology
Wood preservative can prolonging wood use, the wood preservation industry is the important channel of saving the forest resources.But existing wood preservative such as creasote, copper are water ballast preservative etc., can not degrade after use or degradation cycle long, can cause to environment the defective of severe contamination.And an approach that addresses this problem uses the plant resource wood preservative exactly.In growing process, in order to resist the harm of microorganism, insect etc. in surrounding environment, plant corpus self has produced some secondary metabolites, thereby makes plant corpus have the rotten ability of natural corrosion resistant.A lot of Cupressaceae timber (as: Japan cypress, western Western Red Cedar etc.) have excellent natural corrosion resistant ability, and the material of wherein mainly giving the natural corrosion resistant ability of timber is chamenol.
Chamenol (hinokitiol, β-thujaplicin), have another name called Hinokitiol, hinokitol, thujaplicin, chemical name: 2-hydroxyl-4-(1-Methylethyl)-2,4,6-cycloheptatriene-1-ketone, molecular formula: C
10H
12O
2, molecular weight: 164.20.Chamenol is the natural products of the monoterpenes of a tall and erect phenolic ketone skeleton, by the scientist Anderson of Japan in 1948 from Taiwan Japan cypress (Chamaecyparis obtusa sieb.﹠amp; Zucc.var.formosana (Hayata) Rehder.) separate in heartwood.Chamenol has biologically active comparatively widely, and sterilizing ability is strong.Hinokitiol is 10-100ppm to the minimal inhibitory concentration of general bacterium, is 50ppm to Molds and yeasts.The toxic and side effect of hinokitol is very little, to Wistar Female Rats LD
50Be 600-700mg/kg.Chamenol has been applied to the fields such as cosmetics, packaging for foodstuff as a kind of high-efficiency low-toxicity antibacterial agent.
Although initial discovery of chamenol is in the timber with natural corrosion resistant ability, but not yet be applied in the wood preservation field at present, one of them major reason is that chamenol is water insoluble, if adopt organic solvent to process timber, the inevitable fire risk that greatly increases processing cost and processing procedure.Therefore, the present invention proposes a kind of water ballast type chamenol wood preservative and preparation method thereof.
Summary of the invention
Although the present invention can give timber stronger corrosion resistant ability in order to solve the chamenol that comes from natural corrosion resistant timber, because of its poorly water-soluble, the problem that is difficult to use, and a kind of water ballast type chamenol wood preservative and preparation method thereof is provided.
Wood preservative of the present invention is to be made by the chamenol of 0.2～2mol, the cosolvent of 1mol and the tannin extract (calculating mol ratio by content of phenolic hydroxyl groups) of 0.01～1mol according to mol ratio; Wherein said cosolvent is one or more combination in alkaline matter sodium hydroxide, potassium hydroxide, sodium carbonate, potash, ammoniacal liquor; Described tannin extract is one or more combination in larch bark tannin extract, black wattle bark tannin extract, valonea extract.
The preparation method of wood preservative of the present invention carries out in accordance with the following steps: one, cosolvent is made mass concentration and be 0.01%～5% the aqueous solution, stir, make the aqueous solution; Two, be that 0.2～2: 1 ratio is got chamenol and added in the cosolvent aqueous solution according to chamenol and cosolvent mol ratio, abundant stirring and dissolving; Three, be that 0.01～1: 1 ratio adds tannin extract according to tannin extract and cosolvent mol ratio, namely obtain wood preservative; Cosolvent in step 1 is one or more combination in alkaline matter sodium hydroxide, potassium hydroxide, sodium carbonate, potash, ammonium hydroxide; In step 3, tannin extract is one or more combination in larch bark tannin extract, black wattle bark tannin extract, valonea extract.
Wood preservative of the present invention is yellowish to puce liquid, and wood preservative of the present invention is used for treating of wood, processes material and has antifungi ability and the rotten ability of corrosion resistant.Adopt product of the present invention, when the chamenol mass concentration is about 1%, the processing material reaches 100% to the resistance of aspergillus niger (Aspergillus niger), Penicillium citrinum (Penicillium citrinum), wood mould (Trichoderma koningiopsis), and fungus growth is suppressed fully; And to whiterot fungi---Corilus versicolor Quel. (Trametes versicolor), brown rot fungus---the corrosion resistant ability of gloeophyllum trabeum (Gloeophyllum trabeum) can reach strong corrosion resistant grade.
