Description
Technical field
The present invention relates to wooden protective agent of a kind of bion and preparation method thereof, belong to wood technologies field.
Background technology
China is that a timber consumes big country, but annual preservative-treated timber total amount only about 600,000 m3, insufficient timber yield
1%, external typically 10% or so, compared with World Developed Countries and quasi- developed country, gap is very remote.Therefore, in order to protect
China's economic heath sustainable development is demonstrate,proved, saves the limited forest reserves in China, it is necessary to goes into overdrive to develop the wood preservation in China
Industry.
Timber preservative mainly includes oil-type preservation both at home and abroad at present, oil carries preservative and the class of water ballast preservative 3, uses
Most commonly used is water ballast preservative.For oil-type preservation in addition to the toxicity of people and animals and to the influence of environment, its is another
Individual major defect is product surface pollution after processing, while has pungent taste, and these shortcomings limit the application of oil-type preservation
Scope.Oil carries preservative due to energy crisis so that its processing cost is expensive, and organic solvent volatilizees and easily caused in processing procedure
Environmental pollution and cause fire, thus carry preservative in many application scenarios oil and gradually substituted by water ballast preservative.CCA (adds
Chromium copper arsenate) be the water ballast preservative being most widely used in recent years, it is cheap, antiseptic property after processing, mechanical property and
Top finishing is functional, and resistance leachability is strong.But because its toxicity, Europe, the U.S., Japan have gradually forbidden it in civilian field
Close and use.Except CCA, other contain arsenic or the preservative of chromium is also faced with the problem of same.U.S. KOPPERS ARCH, CSI,
The companies such as OSMOSE, German Dr Wolman, Belgian Janssen have carried out the research and development of green lumber preservative, wherein quaternary ammonium copper system
Row (ACQ-C and ACQ-B) it is said that, CuHDO, triazole etc. be most expected to substitute CCA, and have been enter into practicality.But according to correlative study, this
Class preservative to target effect not as copper chromium arsenic class it is effective, cost is of a relatively high, and smell is heavier, influences to operate.Inorganic Boron
Class timber preservative using also there is the history of 50 years or so, it the advantages of be hypotoxicity and broad spectrum antibacterial, but resistance leachability
It is very poor, chemistry is carried out to the molecular structure of boride to improve the expansion such as fixation performance, the U.S., Japan of boride in wood
The research of modification.The sleeper and the m of electric pole about 200,000 that China is now handled with Creosote every year3, scalage is handled with boride
Annual is 250,000~300,000 m3.Over nearly 5 years, the development of the outdoor preserving timber and structural lumber such as agricultural material, gardens material compared with
It hurry up, the preservative used is mainly CCA, and other high poison preservative, being particularly prohibited from using or limited in the world makes
Such as lindane, pentachlorophenol and penta sodium pentachlorophenate still use in China, there are the wheat of enormous amount and the straw of corn in the current north
Stalk resource, can solve the environment-friendly type of wood preservation as main material with the stalk of wheat and corn there is presently no a kind of
Protective agent.
The content of the invention
In view of the above-mentioned problems of the prior art, the present invention provides a kind of wooden protective agent of bion and its preparation side
Method, preparation prepare simplicity, preservative are prepared by primary raw material of stalk, and antiseptic effect is good, and it is low to prepare cost.
To achieve these goals, the technical solution adopted by the present invention is：A kind of wooden protective agent of bion, primary raw material
For stalk and the extract solution of Spartina alterniflora.
The present invention also provides a kind of bion wooden protectant preparation method, has main steps that, by stalk, mutually spends rice
Careless, compound organic solvent is put into autoclave, is heated rapidly to 120 degree to 150 degree and is kept for certain time, liquid is obtained after reaction
Change product and residue, filtrate are distilled, stand, the product liquid that will be finally given, take aforesaid liquid product 1L, and add wood
Vinegar liquid, being slowly added to pH adjusting agent makes liquid adjust pH 6.5 to 7.5.
Further, the compound organic solvent is polyethylene glycol, propane diols, absolute ethyl alcohol, dimethyl acetamide, phenmethylol
Any one.
The beneficial effects of the invention are as follows：Primary raw material of the present invention is stalk and Spartina alterniflora, and cost is cheap, is particularly suitable for
Wheat in Northern main producing region, straw yield is big, adds pyrolkigneous liquid, and liquid is adjusted pH 7 or so by pH adjusting agent so that solvent
In neutrality, stability is high, it is shown experimentally that, this solvent has good antiseptic property, especially has to poplar good
Anti-corrosive properties, and it is nontoxic, and environment-friendly type is high, has not contained the noxious materials such as arsenic or chromium.
