Abstract
The invention relates to a novel method for improving light resistance of a dyed wood veneer. Wood is pretreated according to the structure characteristics and the chemical characteristics of the wood veneer, low-concentration sodium hydroxide is adopted as a treating agent, and the permeability of the wood is improved through an optimal pretreatment technology. In addition, two kinds of light resistance auxiliaries with the different action principles are added in the dyeing process and after dyeing, so that light resistance of the dyed veneer is greatly improved through a composite action, and on the premise that the physical performance and the mechanical performance of the veneer are not affected, the service life of the veneer is prolonged, and the product additional value of the veneer is improved. Compared with a traditional dyeing treatment technology, the novel method is more environment-friendly, low in energy consumption, better in product light resistance performance and obvious in social benefit and ecological benefit.
Description
Technical field
The present invention is a kind of novel raising sunproof method of wood staining veneer, can be effectively improved the light resistance of veneer after dyeing, and cost is low, and environmental pollution is little, simple to operate. It is applicable to improve performance and the added value of colored single palte.
Background technology
Along with the progress of science and technology and improving constantly of people's living standard, people are increasing for the demand of lumber quality and quantity. In recent years, the timber supply amount of China reduces year by year, and timber resources is deficient year by year, especially rare especially as the rare tree that Scobis Diospyroris Ebeni is this kind of. Nonetheless, people but still increase year by year for the demand of timber. Based on this present situation, China supports that the cultivation of artificial fast-growing woods cultivates energetically. It is short that artificial fast-growing woods has growth cycle, and survival rate is high, the advantages such as unit are cultivation amount is big. But fast growing wood tool itself has disadvantages that, so limiting its use. Instantly how efficient and rational China advocates and accomplishes " low-carbon emission reduction, energy-conserving and environment-protective " when processing and utilization timber, the focal point utilizing artificial fast-growing woods to become people therefore. Wood staining technology is a kind of approach rationally efficiently utilizing artificial fast-growing woods. It can give the dull artificial forest wood of color and luster color with the color of famous and precious seeds by dyestuff on the basis of Wood Properties Within not changing, and adds the value of timber itself, makes low timber such as grade be transformed into high timber.
Timber is because containing multiple material easy to change in self chemical property and construction features and Wood abstract, so when timber is subject to external environment illumination, the color of wood surface can change, outward appearance and the value of timber are had a strong impact on, and after dyestuff stained with timber, dyestuff self there is also the metachromatism that fades. Improve the sunproof technology of colored single palte at present and there is the shortcomings such as weak effect, cost is high, environmental pollution is big.
Summary of the invention
Present invention aim at shortcomings such as avoiding conventional raising colored single palte light resistance technology big energy-consuming, cost is high, environmental pollution is big. By wood single-plate pretreatment, add fast light auxiliary agent two-step pretreatment, it is provided that a kind of efficient, low cost raising sunproof technology of colored single palte, and while increasing colored single palte added value, reduce environmental pollution. The purpose of invention is to reach to improve the sunproof purpose of wood staining veneer by following measure. Its technical scheme is: before dyeing, and the broadleaf veneer that thickness is 0.6mm is carried out pretreatment, and treatment agent is the sodium hydroxide solution of 0.4%, and solvent is water. Treatment temperature 90 DEG C, processes 3 hours time, washs with clear water after having processed. Prepare fast light auxiliary agent: the ammonia spirit of aluminium potassium sulfate, aluminium potassium sulfate concentration 3%, ammonia concn 4%. It with dyestuff mixing, broadleaf veneer being dyeed, concentration proportioning is 18:1. After dyeing, at one layer of chitosan-acetic acid solution of veneer external coating, chitosan concentration 2%, acetate concentration 0.8%. Pretreatment in order that improve the Color of timber by improving the permeability of timber, thus improving the light resistance of colored single palte; Aluminium potassium sulfate ammonia spirit and chitosan-acetic acid solution are as two kinds of fast light auxiliary agents, aluminium potassium sulfate ammonia spirit is a class UV absorbent, it can absorb the ultraviolet part in sunlight or special fluorescence light source, such ultraviolet cannot contact with wood surface after being absorbed, thus improving the light resistance of colored single palte; Chitosan it be the de-second phthalidyl product of a kind of chitin N, it constitutes elementary cell is glucosamine, and the hydroxyl on glucosamine unit location of C is replaced by amino. Under certain condition, the amino in chitosan molecule reacts with the sulfonic group in dyestuff, generates sulfonate, forms stable ionic bond, enable chitosan molecule to be securely attached to wood surface; Meanwhile, chitosan or a kind of film forming matter it can form thin film shape material on the surface that be painted material such that it is able to stop extraneous ultraviolet, it is prevented that light source shines directly into wood surface, improves the light resistance of colored single palte.
The technical characterstic of the present invention: according to the construction features of wood single-plate, chemical characteristic, timber is carried out pretreatment, and treatment agent adopts the sodium hydroxide of low concentration, by optimizing pretreating process, Min. must change Wood Properties Within, improves the permeability of timber to greatest extent. And add, with after dyeing, the light resistance auxiliary agent that two kinds of action principles are different in dyeing course, by the very big light resistance that must improve colored single palte of compound action, under not affecting the premise of physical and mechanical property of veneer, improve service life and the added value of product of veneer. Compared with processing technique with traditional dyeing, more environmental protection, energy consumption is low, and product light fastness is better, and social benefit and ecological benefits are notable.
Inventive formulation is reasonable in design, and technical performance is good, and light resistance is strong, and service life increases substantially, and consumed energy is few, and cost is low. Being drawn by ultraviolet case degradation, compared with traditional colored single palte, the colored single palte light resistance that this technology manufactures promotes more than 50%, and added value of product can improve several times.
Detailed description of the invention
The composition of this novel sunproof technology of raising colored single palte includes:
1. pretreatment: treatment agent is the sodium hydroxide solution of 0.4%, solvent is water, treatment temperature 90 DEG C, processes 3 hours time. 2. adding the ammonia spirit of aluminium potassium sulfate in dye liquor: aluminium potassium sulfate concentration 3%, ammonia concn 4%, concentration proportioning is 18:1. 3. brushing chitosan-acetic acid solution after dyeing, chitosan concentration 2%, acetate concentration 0.8%. After treatment, the light resistance of colored single palte is obviously improved, and added value of product improves.
