Abstract
The invention belongs to the wood coloring field and provides a veneer coloring method. The required veneer with the color of pau amarello wood can be obtained after the veneer is treated by a treating agent and irradiated by an ultraviolet lamp. The method comprises the following: the uncolored veneer is treated by water-based preparation, and the preparation includes a bleaching agent, an inorganic stabilizing agent, a pH value regulator and an inducer, wherein the bleaching agent is H2O2, the inorganic stabilizing agent is Na2SiO3, the pH value regulator is Na3PO4, and the inducer is HC1. The treatment method has environmental protection, and the veneer of the white birch after treatment can be used in the fields such as furniture and interior decoration.
Description
Technical field
This patent is that the precious timber ultraviolet light of environment-friendly imitation brings out dye technology, it is a kind of stain for wood method of utilizing the phototropic principle and carrying out in conjunction with inorganic chemical reagent, reagent does not contain arsenic, chromium and other persistence organic pollutant, be mainly used in the imitated para rue timber of artificial forest white birch veneer, when eliminating its surface contaminant, make its coating effect near or reach the color of para cloud incense wood material.
Background technology
Timber is as ecological environment material nd, and is very popular with its unique material property, fine environment characteristic.The color and the human visual system of timber are closely related, and different color belts is given the different visual enjoyment of people.
Along with the variation of forest resources structure and quantity,, the substitute is artificial forest wood in the face of the level high-quality furniture woods supply of the big footpath of wildwood reduces day by day.At present, how to develop the artificial forest resource better, improve its value, become problem demanding prompt solution, and the good timber of some materials not can not get sufficient utilization because of its color reaches good visual effect.
The variation of reacting, issuing living physicochemical properties in the effect of light and heat is decomposed, produced with chemicals to organic components in the timber by microorganism easily, above-mentioned reason finally can cause the destruction of wood structure, and sapstain can be regarded the initial period that reacts as, does not influence the intensity of timber substantially.Ultraviolet light brings out dye technology, it is the veneer that utilizes common tree lumber, remove surface contaminant through the bleaching processing, after the inducing agent processing, through UV-irradiation, different irradiation times can reach different wood color effects, and compare with the dye method stained wood, its wood color has higher brightness value, is a kind of novel dye technology of imitative precious timber.
Summary of the invention
It is a kind of indirect dye technology that ultraviolet light brings out dye technology, is primarily aimed at artificial forest white birch wood veneer, and its coloring process is divided into following three phases:
The bleaching of one white birch veneer is handled
Employed in this patent mainly is artificial forest white birch wood veneer, and its thickness is 0.1mm.
The bleaching inorganic agent mainly contains bleaching agent, inorganic stabilizers, pH value conditioning agent
Bleaching agent: H
2O
2Belong to the oxidized form bleaching agent, in the harvesting of wood and storage transportation, can produce the variable color defective, can effectively remove the sapstain defective that illumination, oxidizing ferment, soda acid, factor such as damp and hot cause by bleaching, both can remove the defective that timber self causes, also the defective that environmental factor and production technology are caused improves significantly.
Inorganic stabilizers: Na
2SiO
3, in veneer bleaching is handled, be to be used for passivation transition metal ion, thereby prevent that metal ion is to hydrogen peroxide (H
2O
2) accelerated decomposition, play and stablize H
2O
2Effect, improve bleaching effect.
PH value conditioning agent: Na
3PO
4, in soup, generate weak acid with the water reaction, make soup be alkalescence, and hydrogen peroxide just help producing the hydrogen peroxide ions (HO of active bleaching under alkali condition
2 -), but excessive alkali can cause the degraded of timber, and Na
3PO
4Relatively stable under thermal environment, be easy to the control reaction.
Two white birch veneer inducing agents are handled
Inducing agent: HCl is meant that accelerating timber by its processing after bleaching brings out painted speed, and improves the red green product index of wood color.UV-irradiation can significantly increase the quantity of ketone group, be that champac chromaticity index increases substantially, in order to obtain higher red green product index, need be by the processing of inducing agent, because phenols component adhering in the timber because of acidic materials, with oxidizing ferment in the timber and airborne oxygen generation oxidation reaction, wood color is red partially; The condensation reaction of acid-base catalysis also easily takes place in the carbonyl in the timber, carbon-to-carbon double bond structure, and further isomerization reaction, changes the color of timber.
Three UV-irradiations are handled
It is beginning that ultraviolet light brings out painted light absorption with timber, the simultaneous chemical reaction, contain the functional group that absorbs ultraviolet light in the timber, as carbonyl, phenol hydroxyl and quinoid structure, different functional group absorbs and wood color deepened behind the ultraviolet light or shoal.Use UV-irradiation timber, the distribution and the structure of chromophoric group and auxochrome group make the wood color homogenization in the adjustment timber, reach needed color effects by adjusting irradiation time.
It is simple, easy to operate that the ultraviolet light that this patent adopted brings out the equipment that dye technology selects for use, can not cause rottenly to timber, do not influence its intensity, do not influence glue performance and cover with paint, lacquer, colour wash, etc. performance, and improved the surcharge of timber.Make veneer colour brilliance value height, can obtain bright and beautiful bright yellow wood color, remedied the deficiency of colouring method.
The specific embodiment
The ultraviolet light that this patent adopted brings out dye technology and was divided into for two steps:
(1) inorganic agent is handled: with water is carrier, handles the white birch veneer by the proportioning to bleaching agent, inorganic stabilizers, pH value conditioning agent, inducing agent.
(2) ultra violet lamp: adopt uviol lamp to shine, can obtain desirable color by adjusting the energy that uviol lamp sends or the time of irradiation.
Claims (1)
1. a veneer method of colouring is characterized in that reaching para rue timber wood color with the method that ultraviolet light brings out.Described method comprises that the use preparation handles uncoloured veneer, and described preparation comprises bleaching agent, inorganic stabilizers, pH value conditioning agent and inducing agent; Wherein bleaching agent is H
2O
2, inorganic stabilizers is Na
2SiO
3, pH value conditioning agent is Na
3PO
4, inducing agent is HCI.
