Embodiment 1

[0028] A method for impregnating and heat-treating wood with a compound anti-mildew preservative solution, comprising the following steps:

[0029] (1) Compounding of anti-mold and anti-corrosion liquid:

[0030] The copper-containing compound impregnating solution is uniformly mixed with the antifungal agent chitosan copper complex solution, camphor tree leaf extract solution, burdock leaf extract medicinal solution and nano-titanium dioxide-Chinese herbal medicine composite antiseptic solution to obtain a compound anti-mold antiseptic solution;

[0031] (2) Pressure impregnation treatment of wood:

[0032] Immerse the wood in distilled water, ultrasonically clean it for 20 minutes, put it in an oven at 60-70°C and dry it to constant weight, and then immerse it in the compound anti-mold and anti-corrosion solution obtained in (1). The gauge pressure under vacuum is - Treat at 0.09MPa for 30min, then impregnate at 1MPa for 40min, take it out, and put it in an oven at 60-70℃ t...

Embodiment 2

[0046] A method for impregnating and heat-treating wood with a compound anti-mildew preservative solution, comprising the following steps:

[0047] (1) Compounding of anti-mold and anti-corrosion liquid:

[0048] The copper-containing compound impregnating solution is uniformly mixed with the antifungal agent chitosan copper complex solution, camphor tree leaf extract solution, burdock leaf extract medicinal solution and nano-titanium dioxide-Chinese herbal medicine composite antiseptic solution to obtain a compound anti-mold antiseptic solution;

[0049] (2) Pressure impregnation treatment of wood:

[0050] Immerse the wood in distilled water, ultrasonically clean it for 25 minutes, put it in an oven at 70-80°C and dry it to constant weight, and then immerse it in the compound anti-mold and anti-corrosion solution obtained in (1). The gauge pressure under vacuum is - Treat at 0.09MPa for 35min, then impregnate at 2MPa for 45min, take it out, and put it in an oven at 70-80℃ t...

Abstract

The invention discloses a method of treating wood by means of impregnation in a compounded mildewproof preservative liquid and high-temperature thermal treatment. The method comprises the following steps: uniformly mixing a copper-containing compound impregnation liquid with a mildew preventive chitosan copper complex solution, a camphor tree leaf extract solution, a burdock leaf extract medicinalliquid and a nano titanium dioxide-Chinese herbal medicine compound preservative liquid to obtain the compounded mildewproof preservative liquid; impregnating wood in water for ultrasonic cleaning, drying the wood to a constant weight, impregnating the wood in the compounded mildewproof preservative liquid to be treated in a vacuum state, then pressurizing and impregnating the wood, taking the wood out, and drying the wood to a constant weight; putting the impregnated wood in a thermal treatment tank, setting the pressure of a steam generator and the vapor carbonizing pressure, and discharging oxygen in the thermal treatment tank after treatment; stopping steam thermal treatment, starting electric heating treatment, and setting the thermal treatment temperature for thermal treatment; andstarting the steam generator and introducing steam into the tank to reduce the temperature to obtain the mildewproof preservative wood. The wood is impregnated and pressurized by the compounded mildewproof preservative liquid, the thermally treated wood is obtained by applying a wood thermal treatment technology, and the mildewproof efficacy of the wood is good.

Description

technical field [0001] The invention belongs to the technical field of wood treatment, and in particular relates to a method for impregnating and heat-treating wood with a compound anti-mold and antiseptic solution. Background technique [0002] Wood is easily corroded by wood-rot fungi during use, resulting in waste of wood and affecting its performance. Water-borne wood preservatives are now widely used, which can achieve a good wood preservative effect during the use process; and the treated wood will cause harm to the ecological environment if it is not treated harmlessly after its service life expires. harm. Therefore, low-toxicity and high-efficiency plant-derived preservatives have become a research hotspot for wood preservatives. Moreover, wood has anisotropic characteristics, and its absorption of wood preservative dose is low. Usually, high-pressure treatment is used to increase the drug loading of preservatives in quick-grown wood to improve the anti-corrosion a...
