Abstract
Application the invention discloses a kind of preparation method of timber preservative and its in wood preservation processing, category wood protection field.The preservative is albumen ammonium copper boron salt antiseptic solution, and sticking agent is poultry feather albumen pyrolytic behavior, and the preparation method of preservative is to be mixed borax and copper sulphate, adds albumen pyrolytic behavior compounding generation albumen ammonium copper boron salt preservative.Method for anticorrosion treatment has normal temperature and pressure dipping, drying process.Experiment proves：Copper sulphate, borax and feather protein occur chemical reaction and form a kind of amino acid metal salt, amino-acid salt, a kind of polymer network not soluble in water can be formed in wood internal, so as to improve the fixation performance of copper, boron in timber to a certain extent.For timber test specimen through preservative treatment than blank test specimen, color becomes blue, but color integrally deepens degree less and will not cover the grain of wood, it is believed that the preservative influences lighter on Wood color.Being tested through corrosion resistant proves that preservative antiseptic effect is preferable.
Description
Technical field
The invention belongs to wood protection field, and in particular to a kind of timber preservative, preservative preparation method and its
Application in wood preservation.
Background technology
The timber preservative that tradition uses due to toxicity, easily bringing harm and pollution to the mankind and surrounding environment,
Such as conventional timber preservative has coal creasote, pentachlorophenol, wherein chromated copper arenate (CCA), coal creasote, pentachlorophenol
There is larger toxicity to environment and people and animals, arsenic and chromium can equally threaten health and environmental quality, therefore be the guarantor that accords with one's environment
The demand of shield, developmental research have an environmental-protecting performance, and the strong preservative of leach resistance is becoming for current timber preservative research
Gesture.
It is soft to environment to person poultry harmless while copper has better inhibition effect to fungi by contrast, in addition, boride
Preservative is also increasing, and boride can make timber from the infringement of fungi, and can protection against insect and toxicity is especially low.By
Copper-based preservative, boryl preservative are mainly respectively applied to wood preservation field by current report, or both are mixed
Composite usage, but copper, boron and organic compound is compound, the reaction system of copper, boron and organic compound chelating is established, generation is more
The research of functional form low toxicity albumen ammonium copper boron salt preservative or product yet there are no report.
The content of the invention
Source of this research using food industry discarded object poultry feather as animal protein, enters in preservative preparatory phase
Hand, animal protein is introduced as organic compound, copper, boron is compound therewith, prepare the chelating albumen ammonium copper boron for forming hypotoxicity
Salt preservative.
In order to make up the deficiencies in the prior art, the first object of the present invention is to provide a kind of material preservative；Second mesh
The preparation method for being to provide the preservative.
What the first object of the present invention was realized in：
A kind of hypotoxicity timber preservative and preparation method thereof, in parts by weight, the preservative contains：Copper sulphate 4-7
Part, borax 5-8 parts, pyrolytic behavior 5-30 parts；Being pyrolyzed liquid and preparation method thereof is：Sulfurous acid is used after fresh feather poultry feather is cleaned
Sodium (NaHSO3) pre-processed, pretreatment time 16-30h, then in sodium hydroxide (NaOH) solution that concentration is 6-8%
It is pyrolyzed, the parts by weight of feather and sodium hydroxide solution are 1 after pretreatment:4-1:10, pyrolysis temperature is 140-160 DEG C, heat
The solution time is 4-8h, then forms pyrolytic behavior；Copper sulphate and borax are measured by the formula rate, at 25-30 DEG C, after mixing
It is dissolved in the water together, the blue suspension of copper sulphate and borax is fully obtained after dissolving, and then adds the pyrolysis of poultry feather albumen
Liquid stirs simultaneously, forms brown dirty solution, that is, obtains the hypotoxicity timber preservative.
Preservative optimization formula of the present invention is：4 parts of copper sulphate, 5 parts of borax, 18 parts of poultry feather albumen pyrolytic behavior.
The present invention is slowly dropped into hydrochloric acid or acetic acid, while stirring and adjusting makes its pH value after the completion of pyrolytic behavior preparation
For 5 or so, ammoniacal liquor is added until solution is clarified to form navy blue settled solution.
The present invention is applied to the method for wood preservation, is impregnated for normal temperature and pressure, and drying process, including walks in detail below
Suddenly：
A, impregnate：Timber test specimen is immersed in preservative at 10-30 DEG C, 24h is impregnated after sealing, each sample is anti-
Rotten before processing quality is referred to as M0, wipe surface liquid away after processing and weigh again and be designated as M1；
B, drying：
1) the wooden test specimen fully permeated by preservative is carried out spontaneously drying 1-2 days in atmospheric conditions by.
2) is 10-12% by being dried by the wood preservation test specimen spontaneously dried at 50-60 DEG C to moisture content.
The invention has the advantages that tests prove that：There is the albumen of chelating in timber preservative of the present invention
Copper boron salt, there is good anchorage, enter timber it is central after, a kind of polymerization not soluble in water can be formed in wood internal
Volume grid, so as to improve the fixation performance of copper, boron in timber, reach the purpose of long-effective corrosion.
In addition, the poultry feather albumen in wood preservation agent prescription of the present invention is natural material, also with source
Extensively, the advantages that nontoxic.The outward appearance of observation evaluation processing material understands, timber by preservative treatment than blank test specimen,
There is no significant change and color is uniform, it is believed that the preservative does not influence substantially on Wood color.After contrasting corrosion resistant experiment
The outward appearance of blank test specimen and anti-corrosion test specimen, the corrosion of blank surface of test piece is extremely serious, and anti-corrosion test specimen maintains good integrity degree
And color and luster, illustrate that the preservative has preferable antiseptic effect to timber.
Brief description of the drawings
Fig. 1 is the mistake matter rate state diagram in different embodiments.
