Abstract
The invention discloses a preparation and use scheme of a novel degreasing and color protection agent used on pine veneer timber, belonging to the wood modification field. The degreasing agent is mainly composed of main agent, inorganic stabilizing agent, pH value conditioning agent and surface-active agent. The color protection agent is mainly composed of main agent, inorganic stabilizing agent and pH value conditioning agent. Under the conditions that the response time is 45 minutes When the degreasing temperature is 70 DEG C, and the response time is 15 minutes when the color protection temperature is 80 DEG C, the inside resin of scotch pine veneer timber can be effectively degreased resin and the changed color thereof can be recovered due to the degreasing. The agent assembly has the advantages of reasonable dispensation and design, perfect technical specification, high degreasing rate, little energy consumption, low cost and the like.
Description
Technical field
The present invention is novel pine veneer material degreasing color preserving agent, does not contain inorganic ions and other persistence organic pollutants such as chromium, arsenic, copper, and is harmless, free from environmental pollution.The color recovery of the veneer variable color that is applicable to the degreasing of pine veneer material and causes because of degreasing.
Background technology
At present along with the enforcement of wildwood protected project, the requirement to the veneer wood product of super quality and competitive price in timber processing and application is increasing, and domestic existing available timber resources can not satisfy this growing demand.China is from a large amount of big footpath of the high-quality level pine timber of the long-term import of Russia and various countries, the Central Asia, but the timber of this high-quality is not used adequately reasonably.Because pine resin content is higher relatively, therefore caused a large amount of wastes and application very little in processing with in utilizing.Pine being carried out ungrease treatment, can enlarge the application of this type of timber, increase its added value, is one of important approach of saving timber, protecting forest resources.
Conventional pine sheet material degreasing medicament mainly contains two kinds of strong basicity degreasing and highly acid degreasings.The most frequently used is strong alkaline water dissolubility degreasing agent, and consumption accounts for about 80% of the total consumption of degreasing agent.Be primarily aimed at thickness and surpass pine sheet material about 30mm, the processing time is long, temperature is high, energy consumption is big, degreasing is inhomogeneous, and is difficult to control for the variation of the surface color of sheet material.The medicament of protecting look after the degreasing of pine sheet material adopts the potion economic benefits and social benefits at present, and control pH value is to reach the purpose that alleviates variable color in degreasing.But the degreasing effect of this kind medicament is not good, and variable color largely still appears in timber, can not keep the original color of sheet material fully.
The object of the invention is to avoid big energy-consuming in the ungrease treatment of conventional pine material, and degreasing rate is low, and color is difficult to shortcomings such as control.By alkalescent degreasing medicament, the two steps processing of guarantor's look medicament, a kind of resin that can effectively remove in the pine veneer material is provided, and makes the color recovery of handling the back veneer arrive the new reagent combination of original color and luster.

Summary of the invention
The objective of the invention is to reach the resin that effectively removes pine veneer material inside, and a kind of novel pine veneer material degreasing of replying the variable color that veneer produces because of ungrease treatment is protected the look medicament by following measure.Its technical scheme is: for thickness is the pine veneer material of 0.7mm, adopts weakly alkaline degreasing medicament that it is carried out ungrease treatment, and the degreasing medicament is water miscible white powder, and main component and content are main body medicine NaOH, stabilizing agent Na
2SiO
3, pH conditioning agent Na
3PO
4, the surfactant NPE.Insoluble resin acid reacts the macromolecular resin acid sodium that generates solubility under alkali condition, this is reflected under the function of stabilizer and can steadily carries out, and progressively diffuses out wood surface under the activation of surfactant.Because the effect of alkalescence, the lignin of part can be degraded, and is attended by the generation of a large amount of two keys, makes the veneer color by light yellow yellow or the buff of changing into.But under 70 ℃ temperature, react 45～60 minutes time, both can effectively remove the inner resin more than 80% of pine veneer materials such as masson pine, Korean pine, larch, pinus sylvestris var. mongolica, the variable color of pine veneer material can be controlled within the recoverable scope again.Veneer wood after the degreasing is protected look through clear water flushing back row and is handled, and protecting the look medicament also is water miscible white powder, and main component and content are main medicine H
2O
2, stabilizing agent Na
2SiO
3, pH conditioning agent oxalic acid.Under 80 ℃ temperature, react 5～15 minutes time, use the oxidation of hydrogen peroxide, under the condition of acidity, can effectively destroy a large amount of color developments and the auxochrome group that produce because of degreasing, the color of veneer is effectively replied, and whiteness value can return back to original more than 98%.
Technical characterstic of the present invention: according to the chemical composition of pine veneer material and the physical characteristic configuration degreasing medicament of plate surface, liquid medicine is alkalescent.By middle high-temperature water heat treatment, can be under the effect of surfactant so that the resin in the veneer is dissolved in medicament, and penetrate the veneer surface, thereby deresinate has effectively equably increased the glue performance of veneer and has covered with paint, lacquer, colour wash, etc. performance under the prerequisite of the physical and mechanical property that does not influence veneer.Design guarantor's look medicament of corresponding veneer wood according to the surface discolouration that under this medicament effect, produces, under the effect of the short time of high temperature hydro-thermal, can reply the variable color that veneer wood produces down because of alkaline oxygenated effect.Compare with the vacuum degreasing processing, can save high pressurization of price and application of vacuum expense; Compare with the degreasing method of routine, can save the cost of drugs expense about 20%.
The present invention fills a prescription reasonable in design, and technical performance is good, the degreasing rate height, and consumed energy is few, and cost is low.Compare with present existing ungrease treatment method, energy resource consumption can reduce more than 20%.
