Abstract

The invention discloses a novel wood preservative comprising the following raw materials: cnidium monnieri, radix sophorae falvescentis, fructus kochiae, radix stemonae, smilax glabra roxb, chinaberry roots, chinaberry bark, and the like. The novel wood preservative adopts traditional Chinese medicines as the wood preservative which has the functions of resisting bacteria and preventing insects, has a certain inhibit function for wood-destroying fungi and is a green environmental-protection material completely. The traditional Chinese medicines have low cost; compared with a chemical agent, the prepared wood preservative can reduce the cost; the traditional Chinese medicines have a simple preparation technology and can save energy consumption, a Chinese medical preparation is mainly prepared by cooking and only needs simpler devices; and the traditional Chinese medicines have good antiseptic effect, are an absolute green resource and have higher environmental safety when being compared with the chemical preservative.

Description

Novel wood preservative

Technical field:

The present invention relates to a kind of anticorrisive agent, relate in particular to a kind of novel wood preservative.

Background technology:

Up to the present; Use always the most and prevent that the method for foxiness from being anticorrosion with chemical agent; Anticorrisive agent produce with use in leakage and ooze out and preservative-treated timber discarded and burn and all can cause adverse effect, and the health of harm humans to environment.Because environmental problem more and more receives people's attention, also become the key of selecting anticorrisive agent.

What current use was maximum is waterborne-type preservation, accounts for anticorrisive agent and uses 3/4 of total amount.Because the scope of the anti-domestomycetes of single anticorrisive agent, worm is narrow, generally two or more anticorrisive agents is mixed by a certain percentage now, the weak point in the time of not only can overcoming single anticorrisive agent and use, but also can produce some new characteristics.At present, compound preservative has obtained in countries in the world using the most widely, and has obtained good effect.Because there are many deficiencies in traditional preservatives, force people to study and seek person poultry harmless, environmentally safe, the new food preservative poisonous only to microorganism.Research is more at present comprise water miscible alkylammonium compounds (AAC), ammonia dissolve alkylamine copper (ACQ), boride, cupric dimethyldithio carbamate (CDDC) and oil-soluble Bravo (CTL), organic iodide (IPBC) etc.For the essence of wood preservation,, develop nontoxic, efficient and practical wood preservation method, reduce environmental pollution, of far-reaching significance to protecting human ecological environment and making full use of existing resource.

Summary of the invention:

The object of the present invention is to provide a kind of cheap, the configuration technology simple, environmental pollution is little, safe nontoxic, efficient and practical novel wood preservative.

The object of the invention is implemented by following technical scheme: a kind of novel wood preservative each component consumption produces effect in the following weight portion scope of stating: frutus cnidii 20-40 part, kuh-seng 10-30 part, fruit of summer cypress 10-30 part, tuber of stemona 10-30 part, smilax 10-30 part.

Each component consumption of the present invention can also be: a kind of novel wood preservative; Frutus cnidii 20-40 part; Kuh-seng 10-30 part, fruit of summer cypress 10-30 part, tuber of stemona 10-30 part; Smilax 10-30 part, chinaberry root skin 20-40 part, windproof 10-30 part, the sub-10-30 part of section, stem of a herb Li 10-30 part, capsule of weeping forsythia 10-30 part, coptis 10-30 part, golden cypress 10-30 part.

The preparation of above-mentioned novel wood preservative mainly adopts traditional Chinese medicines to boil technology,, boils then 30-40 minute about 1 hour with cold water soak earlier; Also have some Chinese medicine extraction process of effective component commonly used, like some fundamental method such as solvent extraction method, steam distillation, sublimed methods.

The invention has the advantages that: adopting Chinese medicine preparation is to have antibiotic, insect protected effect as timber preservative; And domestomycetes also had certain inhibitory action; And be green material fully: Chinese medicine is cheap, compares with chemical agent, and the preparation timber preservative can reduce cost; The preparing process of Chinese medicine is simple, can energy efficient.Chinese medicine preparation mainly is to prepare through decocting, and required equipment is also fairly simple; The antiseptic effect of Chinese medicine is better; Chinese medicine can be described as absolute green resource, and to compare safety of environment property very high with chemical preservative.

Embodiment 7:

Common chemical anticorrisive agent majority all contains heavy metal, people and animals and environment are had harm in various degree, and Chinese herbal medicine is the floristics of spontaneous growth, environment can be described as be perfectly safe.Weigh or represent the degree of medicine acute poisoning, the lethal dose of 50 commonly used is made index, promptly does to supply examination biological with big small white mouse and big white mouse, measures and kills the required metering (mg/kg body weight) of 50% individuality in the colony, is expressed as LD ₅₀Value, all LD ₅₀Big person representes that required metering is many, and drug toxicity is low.The present acute standard of timber preservative avirulence, agricultural chemicals acute toxicity standard can be used as reference like table.

With reference to forestry industry standard LY/T1283-1998 " timber preservative is to rot fungi toxicity test chamber test method ", be test material with the Chinese white poplar, handle sample with Chinese medicine preparation and the timber preservative commonly used of the foregoing description 1-6, carry out indoor corrosion resistant test.Result of the test is following:

The weightless counting rate meter 2 brown rot sample mean weight-loss ratios of table 1 white rot sample mean

Result of the test shows that for whiterot fungi, the antiseptic property that this Chinese medicine is joined has all reached strong corrosion resistant grade, and for whiterot fungi and two bacterial classifications of brown rot fungus, dissolving quaternary ammonium copper chemical preservative with ammonia, to compare effect poor slightly, but better than the antibacterial effect of organic acid anticorrisive agent.It is thus clear that it is feasible adopting Chinese medicine preparation preparation timber preservative, and is the anticorrisive agent of absolute environment-friendly type, has promotion prospect widely.

To use the toxicity of timber preservative and the toxicity work one of part Chinese medicine below always briefly introduces:

The toxicity of frutus cnidii: the toxicity of book on Chinese herbal medicine bibliography record in ancient times frutus cnidii is less.Experiment proof < 15>is given injection frutus cnidii extract 2.0g/kg in the mouse peritoneal, and mouse is movable in the 0.5h reduces, and is sedation, and 48h does not see death.To the slight excitant of skin, to eyes moderate excitant, no sensitization; Cumulative toxicity is the slight property accumulated (K＞5); The result is all negative for Salmonella reversion test, mouse microkernel test, mouse testis sperm mother cell chromosomal aberration test, does not see mutagenesis.

The toxicity of the tuber of stemona: tuberostemonine mouse LD50, quiet notes 62.0mg/kg, oral 1079.4mg/kg belongs to low toxicity.

Fruit of summer cypress toxicity: do not have
