Abstract
The invention discloses a kind of bean dregs albumen timber preservative and preparation method thereof, the preservative is pyrolyzed bean dregs in the basic conditions as bean dregs pyrolytic behavior, then bean dregs pyrolytic behavior is mixed with borax and copper sulphate, compounding generation bean dregs albumen timber preservative.The present invention has advantages below compared with prior art：Copper sulphate, borax and bean dregs albumen occur chelatropic reaction and form 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 extend the service life of preserving timber.
Description
Technical field
Present invention design wood preservation technical field, more particularly to a kind of bean dregs albumen timber preservative and its preparation
Method.
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 albumen is compound, chelatropic reaction system is established, generation Mobyneb albumen base timber preservative
Research or product yet there are no report.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of bean dregs albumen timber preservative.
The present invention is achieved by the following technical solutions：A kind of bean dregs albumen timber preservative, it is characterised in that including
Following components：
Copper sulphate 4-8 parts；
Borax 4-8 parts；
Bean dregs pyrolytic behavior 15-40 parts；
The bean dregs pyrolytic behavior is that bean dregs are obtained by being concentrated after pyrolysis processing, protein in the bean dregs pyrolytic behavior
Mass concentration is 60 ± 5%.
As further improvement of these options, the content of each component is：
4 parts of copper sulphate；
6 parts of borax；
22 parts of bean dregs pyrolytic behavior.
As further improvement of these options, the pyrolysis step of the bean dregs pyrolytic behavior is as follows：
Step 1: pretreatment, takes new fresh bean dreg sodium hydroxide solution to soak as pretreatment, pretreatment time for 10~
12h, the quality of sodium hydroxide is the 6-8% of bean dregs dry weight in mixed liquor；
Step 2: pyrolysis, pretreated bean dregs, which pour into, carries out pyrolysis 4-8h in autoclave, forms the bean dregs heat
Solve liquid.
Bean dregs are adjusted as further improvement of these options, in pyrolytic process and the parts by weight of sodium hydroxide solution are
1:4-1:10, the sodium quality of hydroxide is the 6-8% of bean dregs dry weight in mixture, and the temperature of pyrolytic process is 80-120 DEG C.
The present invention also provides a kind of preparation method of bean dregs albumen timber preservative, it is characterised in that step is as follows：
1., by proportioning step measures copper sulphate and borax, at 25-30 DEG C, be dissolved in the water together after mixing, fully molten
Blue suspension is obtained after solution；
Step 2., stir and add bean dregs pyrolytic behavior, formed taupe dirty solution, that is, obtain the bean dregs albumen timber and prevent
Rotten agent.
As further improvement of these options, step 2. in, be slowly dropped into salt to the taupe dirty solution of formation
Acid or acetic acid, while stirring and adjusting makes its pH value be 5-6, adds ammoniacal liquor up to solution is clarified to form navy blue settled solution,
Obtain the bean dregs albumen timber preservative.
The present invention has advantages below compared with prior art：There is the amino of chelating in timber preservative of the present invention
Sour copper boron salt, there is good anchorage, enter timber it is central after, can be formed in wood internal a kind of not soluble in water poly-
Fit network, so as to improve the fixation performance of copper, boron in timber, reach the purpose of long-effective corrosion；In addition, institute of the present invention
Bean dregs albumen in the wood preservation agent prescription stated is food industry industrial wood waste, also with wide material sources, nontoxic etc.
Advantage.The outward appearance of observation evaluation processing material understands that the timber by preservative treatment is than blank test specimen, without significant change and face
Color is uniform, it is believed that the preservative does not influence substantially on Wood color.Blank test specimen tries with anti-corrosion after contrasting corrosion resistant experiment
The outward appearance of part, the corrosion of blank surface of test piece is extremely serious, and anti-corrosion test specimen maintains good integrity degree and color and luster, illustrates the anti-corrosion
Agent has preferable antiseptic effect to timber.
