Description
Technical field
The present invention relates to a kind of preparation method of natural antibacterial pest repellant, particularly a kind of preparation method who can be used for the natural antibacterial pest repellant of bamboo wood.
Background technology
China's bamboo resource is abundant, and bamboo kind, area, bamboo wood output all occupy first place in the world.The advantage of resource, the input in science and technology that increases day by day, and the industry guide policy of country makes the bamboo industry of China obtain swift and violent development.2005 bamboo annual value of production have reached 59,800,000,000 yuan, and average annual amplification is more than 20%, and directly the practitioner surpasses more than 3,500 ten thousand, about 10.5 hundred million dollars of year foreign exchange earning.Bamboo industry has been called one of four big rising industries of China's forestry, and has the comprehensive competition advantage in the international market.
Yet bamboo is because of containing lot of starch, sugar part, protein and other salts substances, and natural durability is poor, causes easily to damage by worms and mould corruption.Annual because of rotten, the bamboo wood that loses of damaging by worms account for 10% of whole world bamboo wood output, therefore, bamboo wood is antibiotic to have great importance for building the resource-conserving bamboo industry.Yet bamboo wood is antibiotic to be the weak link in China's bamboo utilization, and the bamboo wood of most of outdoor uses is without antibacterial treatment, and minority is unfriendly to environment through the employed antibacterial agent great majority of the bamboo wood of antibacterial treatment.Chemical in recent years antibacterial agent day by day feels a draft because of its known or potential toxic and side effect, and the natural antibacterial agent that is derived from animal, plant, microorganism receives people's favor just day by day.Natural products is not only of a great variety, and biologically active is various, and effect is unique, the more important thing is to be prone to degraded or good with Environmental compatibility, and therefore, from biology, seeking antibiotic active insecticidal components is one of focus of present antibacterial agent research.
The forest extract generally contains more than 700 kind of compounds such as tannin, resin, natural gum, essential oil, pigment, alkaloid, fat, wax, sugar and starch, and the some of them composition is the important source material of chemical industry, medicine and other industrial department, has certain economic and is worth.Some timber extract contains toxic chemical composition, as containing 3,5 dihydroxy benzenes ethene in the pine heartwood extract, contains phenolic ketone in the cypress class timber, all has stronger toxicity.The trees or the bamboo wood that contain toxic extract have stronger natural durability, and the biology of harm bamboo woods such as wood decay fungi, termite is had significant resistance to corrosion.A lot of a bit most natural products compound structures are complicated though natural products has, be difficult for synthetic or synthetic cost too high, have no value for use, most of to photo-labile, or highly volatile, can not directly use usually as antibacterial agent.The way that solves has two kinds, the one, with natural products is modified, modification and be re-dubbed suitable antiseptic prescription; The 2nd, be lead compound with the natural products, develop function admirable and environmentally compatible, antibacterial agent new varieties.
Therefore; According to the natural product chemistry principle,, from plant, extract, screen, prepare natural antibacterial, insect control actives matter through a large amount of tests and research; Through researchs such as formulation development, formulation optimizations, develop the natural antibacterial agent that is applicable to bamboo wood and goods thereof.The enforcement of this patent can reduce bamboo wood antibacterial, worm-expelling cost significantly, promotes the universal utilization of natural antibacterial agent and bamboo wood antimicrobial technology, realizes the sound development of bamboo processing industry, reaches the purpose that economizes on resources, protects environment.
Summary of the invention
Technical problem to be solved by this invention provides the preparation method of the natural antibacterial pest repellant that a kind of operating procedure is simple, controllability good, cost is low.
In order to solve the problems of the technologies described above, the preparation method of natural antibacterial pest repellant provided by the invention is to be made up of following steps:
(1), preparation raw material preparation: benzene/alcoholic solvent and fresh camphortree leaf 2:1～5:1 by volume mix, and then 86～95 ℃ of following extractings 4～6 hours, after the filter paper filtration, obtain camphortree leaf benzene/alcohol extract, i.e. the preparation raw material I; Benzene/alcoholic solvent and China fir powder 2:1～5:1 by volume mix, and then 86～95 ℃ of following extractings 4～6 hours, after filter paper filters, obtain China fir benzene/alcohol extract, i.e. the preparation raw material II; The preparation raw material III is the alcohol saturated solution of camphor; Wherein benzene/alcoholic solvent is to be mixed according to volume ratio 1:2 by benzene and ethanol; The camphortree leaf plucking time be June to September, be Hunan or Jiangxi vegetatively; The China fir powder is that Chinese fir timber and industrial wood waste pulverizing are 10～100 purpose wood powders;
(2), natural antibacterial pest repellant preparation: according to volume ratio V
The preparation raw material I: V
The preparation raw material II: V
Preparation The raw material III=(1～3): (2～6): (3～5), preparation raw material I, preparation raw material II, preparation raw material III are evenly mixed, obtain can be used for that bamboo wood is antibiotic, the natural antibacterial pest repellant of expelling parasite.
Adopt the preparation method of the natural antibacterial pest repellant of technique scheme; Produce in camphortree leaf benzene/pure extract, China fir benzene/pure extract, the camphor ethanolic solution immersion bamboo wood cell; React with the bamboo wood composition, break off the mould food chain, suppress the bamboo wood fungus growth to reach; The generation that bamboo wood goes mouldy can be effectively contained, near the insect of bamboo wood can be driven away simultaneously.Of the present inventionly have that operating procedure is simple, favorable reproducibility, need not any expensive device, also do not need the complex chemical treatment process; What is more important; Bamboo wood after the present invention handles is nontoxic, environmentally friendly, so the present invention has the good industrial application prospect.
In sum, the present invention is the preparation method of the natural antibacterial pest repellant of the bamboo wood that a kind of operating procedure is simple, controllability good, cost is low.
