Abstract

The present invention relates to a wood treatment technology, and provides a method for inducing the color changing of a wood. The method comprises: immersing a selected wood in a previously prepared metal ion sulfate solution for 1 h at a temperature of 80 DEG C, carrying out water washing, and drying under a certain condition, wherein the metal ion sulfate solution is any one selected from the sulfate solution of metal ions such as Na<+>, Fe<2+>, Cu<2+> and Mn<2+>, the concentration of the solution is 10%, the heat treatment temperature of the heat treatment process is 80-130 DEG C, preferably 120 DEG C, and the heat treatment time is 8-20 h. With the application of the method of the present invention to treat the wood, the chromatic value of the treated wood is high, the treated wood is dark red or dark yellow, the color is uniform, stable and comfortable, and the use value of the low color quality wood is improved.

Description

A kind of method that grafting metal ion induces sapstain
Technical field
The present invention relates to the coloring treatment technology and stained wood of a kind of timber, belong to wood processing technique field.
Background technology
Timber is the natural material of a kind of renewable and reusable edible, is woodwork, artificial plate surface with beautiful decorative pattern and gorgeous color With the optimal material of interior decoration.The color of timber is one of wood surface property, wood quality and value evaluation index.With wildwood Timber and precious timber yield fall sharply, and the quality of scondary forest and artificial forest wood is far from meeting woodwork, artificial plate surface and interior decoration etc. Demand.For many years, people optimize, such as to improve the quality of colour of scondary forest and artificial forest wood and the value of Geng Gao in wood color： The aspect such as " dyeing of timber ", " woodwork and wood-based plate incrustation ", " toning of timber " is conducted extensive research and practice.Using chemistry dye Although expecting the ornamental and aesthetic values that woodwork can be improved to Dyeing Wood process, chemical staining is limited due to its intrinsic defect System.As being grown to even greater heights for environmentally friendly cry be restricted with the use of dyestuff, people are more urgent to the demand that environment-friendly type wood color regulates and controls new technology. It is easy to be heated using timber, the extraneous factor such as wet affects and the feature of color change occurs, sapstain is incorporated into into wood color, and to regulate and control this new Research field, induced coloration can make the color of low chromaticness timber tend to the color of precious timber, have with efficient utilization to the processing of the science of timber important Scientific meaning.
Now there are some researches show, heat treatment makes lignin and extract produce conjugation chromonic structures and causes that wood color is different degrees of to be deepened, but is difficult real Now the orientation of wood components structure and color is regulated and controled.Sapstain can be induced by adding metal ion, variable concentrations are added in wood components Fe2+、Na+、Mn2+、Cu2+Deng the inorganic salts of metal ion, the different color of wood formation can be induced.Contain methoxyl group, hydroxyl in lignin molecule Base and carbonyl, these function bases can form different colors as the adsorption site of metal ion and its color development complexing.Tannin intramolecular has multiple neighbours Position phenolic hydroxyl group, can form cyclic chelate, in complexing as multidentate ligand and central ion (such as iron, copper, zinc metal ion) complexing While there is redox reaction, tannin autoxidation color burn into quinone.
Chromonic structures are conjugated using chemical grafting (grafting metal ion) the control timber of heat chemistry catalysis and wood components conjugated system avtive spot Change, induction wood color changes, and is that the application of wood color orientation control technique lays the foundation.This patent proposes regulation and control wood color New approaches and new method, have great importance and practical value to improving wood quality and efficient utilization timber resources.
The content of the invention
The purpose of the present invention is the problem existed for above-mentioned prior art, there is provided one kind induces timber and becomes by grafting metal ion in heat treatment process The method of color.The inventive method equipment needed thereby small investment, process cycle is short, process is simple, low production cost, production safety, without chemical dye and Water pollution, using convenient.The timber of different-thickness can be processed, the wood color after discoloration is stablized, good stability of the dimension, keep timber mechanics While performance, the preservation of timber against decay performance is improved.
To realize the purpose of the present invention, the present invention provides a kind of method of induction sapstain, including to timber metal ion grafting is carried out, and to transferring The timber for having connect metal ion is heated under uniform temperature and time, makes the uniform color attractive in appearance of wood formation.Specific implementation method is as follows：
Timber to be changed colour is chosen, Na to be grafted is impregnated in+、Fe2+、Cu2+、Mn2+In a metal ion species sulfate liquor in, Sulfate liquor concentration is 8～12%, 80～130 DEG C for the treatment of temperature, and heat treatment time is 8～20 hours.After dipping terminates, the metal by grafting The timber of ion takes out from solution, it is scrubbed after carry out vacuum drying treatment, the moisture content of timber is 6～12% after being dried.
Wherein, the grafting metal ion described in said method is Na+、Fe2+、Cu2+、Mn2+Any one of metal ion sulfate liquor.
Wherein, described metal ion sulfate liquor concentration is 8～12%, preferably 10%.
Wherein, 80～130 DEG C of described heat treatment process heat treatment temperature, preferably 120 DEG C.
Wherein, described heat treatment process heat treatment time is 8～20 hours, preferably 12 hours.
Wherein, the moisture content of timber is 6～12%, preferably 8～10% after dried process.
The induced coloration processing method of the present invention has the following advantages：
1st, present invention induction sapstain makes the color of the close rare tree of wood formation, and the wood color after discoloration is uniform, stable, while improving The dimensional stability and corrosion resistance of timber, improves the use value of low quality of colour timber.
2nd, the method for present invention induction sapstain, operation is simple, using convenient, low production cost, added value of product height.
3rd, the present invention overcomes due to the problem of environmental pollution caused using waste water is produced of dyestuff in stained wood production process, reaching The purpose of environmental protection.Meanwhile, discoloration wood will not threaten without organic dyestuff addition to health, safety and environmental protection.
Specific embodiment
With reference to example is embodied as, the present invention is described in detail：
Embodiment 1
Locust tree timber, place of production Heilongjiang Province, life in 6 years.The sample of 100 × 40 × 20 (length × width x thickness) is made, the tangential and footpath for selecting color homogeneous To two sides as test surfaces.By FeSO4It is configured to the solution that concentration is 10%.Test specimen is immersed in above-mentioned solution, keeping temperature is 80 DEG C, dipping Clean water is used after 1 hour.It is placed on again in baking oven, under 80 DEG C of steady temperature, is dried 12 hours, moisture content is 10% after being dried.
