Abstract
The invention provides a combined bleaching agent for timber. The combined bleaching agent comprises the following main components in weight ratio per 1000 ml of solution : 15-75 g of sodium percarbonate; 5-30 g of sodium perborate; 2-8 g of sodium thiosulfate and 12-50 g of sodium sulfate. The combined bleaching agent provided by the invention has higher use security and good bleaching performance; with the adoption of the bleaching agent, dark spots, mineral lines, blue stain and the like on the timber surface and the phenomena that the timber color is uneven caused by various pollutions can be eliminated, and the color difference of heartwood can be eliminated; the overall timber color can be diluted, so that the timber surface can become white and bright and uniform in color and luster; and moreover, the original timber texture and quality can be maintained, particularly the blue-green heartwood of North American liriodendron wood can be repaired better; the bleached timber is in light yellow color, which is very attractive. The processing method further can be used for reducing the white degree reducing trend caused by phototropy, so that the light resistance performance of the timber surface can become more ideal.
Description
Technical field
The present invention relates to a kind of Wood Bleaching agent, specifically a kind of combination bleaching agent of timber.
Background technology
Along with improving constantly of living standard, people seek " green " living environment of back to nature more and more urgently.Therefore, timber, as a kind of natural material, is widely used in building, finishing and upholstery more.But, with regard to global resources, the shortage of resources of large footpath level high-quality timber, natural precious material, the good material quantity that surface aesthetic is beautiful is fewer and feweri, the substitute is a large amount of scondary forests and artificial forest wood, wherein the color and luster of most of timber is even not, pure, and wood color is darker, in addition timber produces in storage, process variable color, pollution etc., be very limited its application at the aspect such as furniture, finishing.This just forces us to explore the former wood color to timber or wood color is inhomogeneous processes, and namely timber is bleached.
The main component of wood cell wall is cellulose, hemicellulose and lignin.Cellulose and hemicellulose do not absorb visible ray, and the lignin being present among cellulose microfibre as matrix is main substance that show color, its basic structural unit is phenylpropyl alcohol alkyl, phenyl ring wherein, the carbonyl (>C=O) of quinones and monomer whose side chain, in carboxyl (C=O-OH), all contain carbon-oxygen (C=O), the chromophoric group of carbon-carbon (C=C) conjugated double bond structures, it is the important sources of color in timber, a large amount of hydroxyl (OH) and methoxyl group (OCH2) auxochrome groups that exist in wood components, a kind of potential chromophore because of.The bleaching process of timber, utilizes oxidation, the reduction reaction of chemical agent at wood surface exactly, destroys chromophoric group (as C=C, C=O) or the sealing auxochrome group that in timber, can absorb visible ray, and its generation is brightened and decolorization; The chemical agent using generally divides two kinds of oxidized form and reduced forms.The main medicament of oxidized form is oxide or peroxide, and reduced form mainly contains sulfide and other acids.The structure that Wood Bleaching is removed lignin in slurry by the effect of chemicals or changed lignin chromophoric group realizes.
Traditional Wood Bleaching generally adopts the methods such as chlorination, hydrogen peroxide bleaching, hydrogen peroxide+ammoniacal liquor, but these methods often have harmful effect or environment are had to pollution operator ' s health, and, bleach by existing formula, the phenomenons such as blackspot, mineral line and the blue change of wood surface are difficult to eliminate clean, wood color dimness after processing, affects attractive in appearancely, is therefore eliminated gradually.Current, in order to meet the needs of multiple bleaching effect, several bleaching agents mix and use, and add the application of compound formula of activate or inhibitionization auxiliary agent increasingly general.
Summary of the invention
For the existing problem of above-mentioned prior art, the object of this invention is to provide good, the consuming time short combination bleaching agent for Wood Bleaching of a kind of bleaching effect.
For achieving the above object, the technical solution adopted in the present invention is: a kind of combination bleaching agent of timber, be characterized in that its key component includes SODIUM PERCARBONATE, sodium perborate, sodium thiosulfate and sodium sulphate, the weight proportion of described each component in 1000ml solution is: SODIUM PERCARBONATE 15 ~ 75g, sodium perborate 5 ~ 30g, sodium thiosulfate 2 ~ 8g, sodium sulphate 12 ~ 50g.
Wherein, for to reach best proportioning effect, the weight proportion of above-mentioned each component in 1000ml solution is: SODIUM PERCARBONATE 50g, sodium perborate 22g, sodium thiosulfate 5g, sodium sulphate 30g.
Sodium sulphate of the present invention can be used one or more replacements in sodium phosphate trimer, sodium metasilicate or sodium acid carbonate.
In order to improve the bleaching efficiency of this bleaching agent, the present invention also includes adjuvant component: tetraacetyl ethylene diamine, the weight proportion of described adjuvant component in 1000ml solution is 5 ~ 30g.
For the acid-base value of regulator solution, better to promote the dissolving of sodium perborate, the present invention also includes adjuvant component: NaOH, the weight proportion of described adjuvant component in 1000ml solution is 0.3 ~ 3g.
The present invention is owing to selecting active oxygen reserves high, the relatively low SODIUM PERCARBONATE of price is main component and sodium perborate in combination bleaching agent, the composition combinations such as sodium thiosulfate, utilize SODIUM PERCARBONATE nontoxic, odorless, pollution-free, be easy to dissolve, the characteristics such as strong detergency with and the aqueous solution be alkalescence, thereby be decomposed into sodium carbonate and hydrogen peroxide and play the effect of bleaching and sterilizing, and SODIUM PERCARBONATE and other bleach compatibilities good, the mixed type bleaching agent being combined into has higher safety in utilization, and bleachability is good, both can eliminate the blackspot on face, mineral line, the blue unequal phenomenon of wood color that becomes and caused by various pollutions, again can be by wood color entirety light color, face is bleached, brighten, color and luster is even, but also can slow down the whiteness downward trend that phototropic causes, make the light fastness of face comparatively desirable.Especially have good repair for yellow poplar timber blue-green heartwood, it is faint yellow that after bleaching, timber presents one, approaches the natural wood color of timber, very attractive in appearance; Again owing to having added tetraacetyl ethylene diamine in mixed bleach liquid; it can make bleaching liquor have superior cold bleaching performance as assistant activator; can play a good protection to lumber fibre; effectively reduce the energy consumption of factory; save time; reduce costs, and alleviate environmental protection pressure and the social pressures that factory bears; Owing to adding NaOH in order to regulator solution pH value in mixed bleach liquid, can further optimize like this bleaching environment again, more be conducive to improve Bleaching Quality.
