Abstract
The invention relates to a blue stain and mildew preventing processing method for masson pine timber. The method comprises the steps of: agitating 0.05-0.15% of thiophanate-methyl, 0.05-0.15% of carbendazim and 0.50-1.00% of double alkyl chain quaternary ammonium salt, with a solvent which is water or 75% alcohol uniformly to prepare a blue stain and mildew preventing liquid for masson pine timber; then quenching the masson pine timber naturally dried by the blue stain and mildew preventing liquid for masson pine timber for 10-20min; or processing fresh pine by way of painting or spraying, naturally drying the fresh pine and spraying for 2-3 times, and then stacking the masson pine timber processed by the blue stain and mildew preventing liquid for masson pine timber in an open type and naturally drying. The method provided by the invention can effectively inhibit propagation of various blue-stain fungi and moulds on the masson pine timber, has remarkable antibacterial effect and is simple in operational process with low processing cost, low using concentration of insecticide and low toxicity.
Description
Technical field
The present invention relates to a kind of masson pine timber preserving method, specifically is the processing method of the anti-blue stain mildew-resistant of a kind of masson pine.
Background technology
Masson pine is the southern main timber tree species of China, and economic worth is high, is main materials such as China's civil engineering, furniture, interior decoration, industrial packaging.But masson pine timber very easily receives infecting of blue stain bacterium and mould in depositing process, cause sapstain.Though wood staining fungi can not cause the rotten of timber, can make timber blackening, paleness or become blue, cause face to pollute, seriously reduce the quality of timber, influence its outward appearance, thereby cause serious economy loss.The successful technology that prevents timber blue stain look on producing at present mainly is to depend on chemical agent to handle.Chemical prevention adopts the sterilization soup to dip or spray the intrusion that wood surface prevents fungi.Anticorrisive agent commonly used comprises penta sodium pentachlorophenate, creasote, copper 8-quinolinolate, copper naphthenate, zinc naphthenate, boride (boric acid and borax), 3-iodo-2-propynyl first propylhomoserin butyl ester, triazole type, Bravo, water-soluble chromatize copper arsenate CCA class etc.Penta sodium pentachlorophenate is a kind of bactericide of broad-spectrum high efficacy, and is very effective to the control sapstain.But it is found that the toxicity grievous injury human health of penta sodium pentachlorophenate afterwards, pollution of ecological environment, many countries ban use of, and this has impelled people to remove to seek other alternative medicament.CCA class Wood protecting agent has potential arsenic and heavy-metal pollution, uses in Japan and the total ban of European many countries, and the U.S. forbids in 2004 that also handling timber with CCA gets into furniture and building construction market.Mantoquita series fungusproof anti-corrosion agent has color, influences the timber outward appearance, thereby is restricted.
Along with the enhancing of economic development and people's environmental consciousness, the development of wood protection technology, all the time around this core of environmental protection, searching low toxicity, the timber preservative that security is good are research directions from now on.
Summary of the invention
The processing method that the purpose of this invention is to provide a kind of anti-blue stain mildew-resistant of masson pine timber.This method can effectively suppress various blue stain fungies and the growth and breeding of mould on masson pine timber, and fungistatic effect is obvious, and operating procedure is simple, and processing cost is low, low, the low toxicity of medicament working concentration.
The present invention achieves the above object through adopting following technical scheme: a kind of processing method of anti-blue stain mildew-resistant of masson pine timber comprises the steps:
(1) the anti-blue stain mildew-resistant liquid of configuration; The active ingredient mass percent is thiophanate-methyl 0.05～0.15%, carbendazim 0.05～0.15%, two ten alkyl-dimethyl ammonium chlorides 0.50～1.00%; Solvent is water or 75% alcohol, stirs, and processes the anti-blue stain mildew-resistant liquid of masson pine timber;
(2) with fresh masson pine sawn timber, without drying, scrape, drying is 1 ~ 2 day under the natural conditions;
(3) chemicals treatment: the masson pine timber after air dry handled is used and is stated under the anti-blue stain mildew-resistant liquid normal temperature and pressure of the masson pine timber that configures cold soaking and handle 10～20min; With the brushing or the spray mode handle fresh pine, after the air dry, be coated with again and spill 2 ~ 3 times,
(4) drying: will prevent the masson pine timber after blue stain mildew-resistant liquid is handled, open stacking, air dry.
The present invention carries out the Preliminary screening of chemical prevention reagent combination and concentration through the inhibition zone test; The indoor anti-blue stain mould proof test that respond well medicament configuration variable concentrations solution carries out masson pine be will suppress again, the medicament and the prescription that effectively prevent the masson pine variable color filtered out.
Outstanding advantage of the present invention is:
1, research shows; The bactericide of the equal equal consumption of low concentration; The fungistatic effect of the bactericide of single prescription on Pinus massoniana material is relatively poor; Use not obviously to the growth inhibited effect of masson pine blue stain bacterium separately like two ten alkyl-dimethyl ammonium chlorides or carbendazim, but two kinds of medicaments or various medicaments and assistant mix to use than use separately and have better effect, can reach tangible bacteriostasis efficacy.
2, masson pine protection reagent of the present invention can be used for the wood protection field; Timber blue stain bacterium Botryodiplodia theo-bromae and pinecone shell spore there are the obvious suppression effect, especially moulds such as trichoderma asperellum, yellow green trichoderma, dark green trichoderma are suppressed better effects if, have broad spectrum activity.
3, prescription is simple, and easy to use, composite reagent synergy significantly reduces dosing; Reduced the concentration of bactericide, minimum effective inhibition concentration is 1/10th of a penta sodium pentachlorophenate, reduces processing cost; The technology that simplifies the operation, fungistatic effect is obvious, has effects such as efficient, low concentration, low toxicity.
