Description

A method of rapid dyeing being carried out to wood single-plate using oriental blueberry leaf
Technical field
The present invention relates to a kind of methods carrying out rapid dyeing to wood single-plate using oriental blueberry leaf, belong to wood staining technology Field.
Background technology
With the development of science and technology and materials processing industries, for wooden resource as raw material, application range is increasingly wide General, the material property that the self structure and chemical composition of wooden resource are constructed also increasingly receives an acclaim, especially natural ring Guaranteed cost.But it is in short supply due to timber, in addition the dullness of timber color itself, cannot increasingly meet the material requisite of people, Start to carry out dyeing processing to timber thus, enriches the decoration performance of timber.Currently, it is acid dye that wood staining, which is applied at most, Material, chemical dye are handled by the wood chemistry of early period, then carry out later stage dyeing to timber, and dyeing is complicated, is wanted to equipment It asks high, and produces modifying porcelain problem, be not suitable for the higher and higher feelings of large-scale production, especially environmental requirement Under condition, this demand is increasingly prominent, and many enterprises do not have sewage disposal device, and chemical treatment soaking water is directly discharged into underground Or river water, very big pollution is caused to soil and environment, is punished by government, influences normal production.
South candle, also known as blueberry, are ericad, in China, distributed pole is wide.It is recorded according to book on Chinese herbal medicine, Smilax application is gone through History is long, can strengthening the essence gas, strengthening the bones and muscles, improving eyesight, beneficial stomach and Psoralen marrow etc., and it is reported that Smilax have promote to regard it is red Element synthesizes again, Vp model machines energy, improves a variety of physiology of blood microcirculation, antiulcer, anti-inflammatory, anti-aging, stopping leak, antibacterial etc. and lives Property.Currently, the research about oriental blueberry leaf not yet causes enough attention both at home and abroad, belong to undeveloped plant resources.Although have by It is applied to the research on food, but it is very few to apply it to the research on woodwork.
Invention content
It is an object of the invention to solve the deficiencies in the prior art, provides and a kind of timber is quickly contaminated using oriental blueberry leaf The method of color.
Technical solution
A method of rapid dyeing being carried out to wood single-plate using oriental blueberry leaf, is included the following steps：
(1) wood single-plate is dried at 45-55 DEG C, until weight does not change；
(2) wood single-plate after drying is immersed in ethanol solution, heating carries out boiling, then pulls out, is rushed with distilled water After washing, it is put into dry kiln and dries to moisture content 6-10%；
(3) wood single-plate after drying is immersed in oriental blueberry leaf extracting solution, then 75-85 DEG C of immersion 1-3h is pulled out, carried out Cleaning, drying, that is, complete dyeing course.
Further, in step (2), volumes of aqueous ethanol a concentration of 10%.
Further, in step (2), boiling temperature is 80-90 DEG C, time 2-3h.
Further, in step (2), when boiling, above container plus preservative film sealing, ethanol evaporation is prevented.
Further, in step (3), the preparation method of the oriental blueberry leaf extracting solution：By the fresh south candle within the 3d of picking After leaf is cleaned with distilled water, it being cut into leaf item, leaf item is put into 75-85 DEG C of distilled water, then stirring extraction 1-3h is filtered, Obtained liquid is oriental blueberry leaf extracting solution.The solid-liquid ratio of leaf item and distilled water is preferably 1：120(g/ml).
Beneficial effects of the present invention：The present invention selects natural dye oriental blueberry leaf as coloring agent, pure natural pollution-free, has Preferable biodegradability and Environmental compatibility, are good for the environment, and oriental blueberry leaf also has the health-care effects such as antibacterial.This hair Bright colouring method is low for equipment requirements, easily operated and controllability is strong, can be used for large-scale industrial production.Using the present invention Colouring method obtained by the gorgeous full, even dyeing of color of colored single palte, the water fastness of dye liquor is high, upper dye is strong and dyeing kinetics Soon, minimum to the destructiveness of timber, and without any Form aldehyde release, color is lasting, is suitable for decorative overlay material and interior The higher indoor furniture material of PARA FORMALDEHYDE PRILLS(91,95) concentration requirement.
Specific implementation mode
The present invention is further explained in the light of specific embodiments.
Embodiment 1
It chooses 3 pieces of white oak veneers (number 1-1,1-2,1-3) and 3 pieces of Oak veneers (number 1-4,1-5,1-6) carries out Dyeing, board dimension are 50mm × 60mm × 2mm.Colouring method includes the following steps：
(1) wood single-plate is dried at 50 DEG C, until weight does not change；
(2) wood single-plate after drying is immersed in 10% ethanol solution, is heated to 85 DEG C of boiling 2.5h, between veneer It is separated with glass bar, it is ensured that maceration extract is uniformly impregnated with, and vessel port adds preservative film to seal, and prevents ethanol evaporation；Then it pulls out, with steaming After distilled water is rinsed, it is put into dry kiln and dries to moisture content 6%；
(3) oriental blueberry leaf extracting solution is prepared：After fresh oriental blueberry leaf within the 3d of picking is cleaned with distilled water, it is cut into The leaf item of 0.5cm wide, 2.0cm long, leaf item are put into 80 DEG C of distilled water, solid-liquid ratio 1：120 (g/ml), stirring extraction Then 1.5h is filtered, obtained liquid is oriental blueberry leaf extracting solution.Wood single-plate of the step (2) after dry is immersed into oriental blueberry leaf In extracting solution, 1.2h is impregnated, is then pulled out, is cleaned, dried, that is, complete dyeing course.
One, front and back chromatism test is dyed
White oak veneer (number 1-1,1-2,1-3) before dyeing and Oak veneer (number 1-4,1-5,1-6) front 3 points are randomly selected, are measured with X-rite RM200 color difference meters, recording parameters are averaged, and specific data are shown in Table 1.It adopts After the dyeing of the method for embodiment 1, measurement markers point chromatic value and record again, using CIE (1976) L*, a*, b* color Degree learns parameter and calculates △ L*, △ a*, △ b* and △ E*, is specifically shown in Table 2,
△ E*=(△ L*2+△a*2+△b*2)1/2
In formula：△ E* are aberration, and also known as overall aberration, the bigger expression measured object of numerical value and control sample color distinction are bigger, Criterion is shown in Table 3.
Aberration before 1 white oak of table, the dyeing of toothed oak wood
Aberration after 2 white oak of table, the dyeing of toothed oak wood
3 value of chromatism of table and people's naked eyes visual sense feeling relationship
According to the value of △ E*, that is, dye the difference of front and back chromatic value, it can be seen that after method dyeing using the present invention, aberration Value is all 12.0 or more, and color distinction is very big before and after showing single-plate dyeing, and coloring is good.
Two, chromatism test after washing
By the white oak veneer (number 1-1,1-2,1-3) and Oak veneer after the colouring method dyeing using embodiment 1 (number 1-4,1-5,1-6) is put into the beaker for filling distilled water and seals, and in water-bath after 80 DEG C of heating 3h, takes out nature and dries in the air It is dry, and chromatic value is measured again in mark point.Record sheet is established to calculate using CIE (1976) L*, a*, b* chromatic value △ L*, △ a*, △ b* and △ E*, △ E*=(△ L*2+△a*2+△b*2)1/2.Specific data are shown in Table 4.The smaller then phase of value of chromatism The washing fastness answered is bigger.
Aberration after 4 white oak of table, the washing of toothed oak wood
According to the value of △ E*, that is, wash coloration value difference later, it can be seen that after the colouring method dyeing of embodiment 1 Veneer, it is little to wash front and back aberration, and it is good to show to dye white oak, the effect of toothed oak wood using colouring method of the present invention, and is not easy It fades.
