Embodiment 1

[0012] A preservative for wood treatment, the composition of which is proportioned by mass percentage: 15% disodium octaborate tetrahydrate, 15% methyl 2-benzimidazolyl carbamate, 10% dithiocyanomethane, and bromonide Propanol 5%, sodium pyrithione 2%, p-chloro-m-xylenol 10%, DCOIT 8%, didecyl dimethyl ammonium chloride 6%, glycerol 2%, fatty alcohol polyoxyethylene Ether 2%, water 25%.

[0013] Preparation method: (1), weigh each component according to the weight ratio; (2), mix disodium octaborate tetrahydrate, methyl 2-benzimidazolyl carbamate, dithiocyanomethane, bronopropanol and Sodium pyrithione is added to the mixer and mixed evenly, then water is added, and p-chloro-m-xylenol, DCOIT, didecyl dimethyl ammonium chloride, glycerol and fatty alcohol polyoxyethylene ether are added to make them together Stir for 20-40 minutes, and then ultrasonically disperse for 10-20 minutes to obtain the above-mentioned preservative for wood treatment.

Embodiment 2

[0015] A preservative for wood treatment, the composition of which is proportioned by mass percentage: 10% disodium octaborate tetrahydrate, 10% methyl 2-benzimidazolyl carbamate, 5% dithiocyanomethane, bromonide 2% propanol, 2% sodium pyrithione, 3% p-chloro-m-xylenol, 4% DCOIT, 2% didecyl dimethyl ammonium chloride, 1% glycerol, fatty alcohol polyoxyethylene Ether 1%, water 60%.

[0016] The preparation method is the same as in Example 1.

Abstract

The invention discloses a wood processing preservative and a preparation method thereof. The wood processing preservative comprises the following components by mass: 10%-15% of disodium octaborate tetrahydrate, 10%-15% of 2-benzo imidazole methyl carbamate, 5%-10% of dithiocyano-methane, 2%-5% of bronopol, 1%-2% of sodium pyrithione, 3%-10% of parachlorometaxylenol, 4%-8% of DCOIT (4,5-dichloro-2-n-octyl-3-isothiazolone), 2%-6% of didecyldimethylammonium chloride, 1%-2% of glycerol, 0.5%-2% of fatty alcohol polyoxyethylene ether and 25%-60% of water. The beneficial effects are that the wood processing preservative has excellent anti-corrosion, mouldproof, sterilization and insect-control functions, has strong ability to kill and inhibit a variety of decay fungi and moth and the like, and the wood processing preservative is good in environmentally friendly property, low in cost and stable in performance.

Description

technical field [0001] The invention relates to the technical field of wood treatment agents, in particular to a preservative for wood treatment and a preparation method thereof. Background technique [0002] As a natural and renewable resource, wood has the advantages of beautiful texture, natural color, comfortable texture, good plasticity, and easy processing, so it is used as an ideal material for building decoration and furniture manufacturing. On the other hand, wood has obvious biological characteristics, is prone to mildew and decay, and is easy to be eaten by insects, which seriously affects the use effect and application field of wood. Therefore, before the wood is used, the appropriate preservatives are often selected for necessary protective treatment, which can prolong the service life and improve the performance. At present, the most used wood preservatives are copper salt-based preservatives, which are low in cost but poor in loss resistance and cause great d...
