(74) Plenipotentiary: Hofman-Bang & Boutard Patent Office (54) Wood and wood preservative

The present invention relates to a means for preserving wood and wood products of the kind set forth in the preamble of claim 1.

It is known that numerous carbamates and thiophosphoric esters exhibit good insecticidal activity. These compounds are therefore mainly used as a pesticide for harmful organisms, plant protection products (cf., among others, German patent specification no.

1 137 893), as pesticides and the like, for direct or indirect control of harmful insects. When these insecticides are used as plant protection products, it is frequently necessary that they be degraded after a certain period of time so that no damage to humans or animals occurs in food uptake. It is desirable that these insecticides on the plants can be rinsed with water so that vegetables and fruits that have been treated with these insecticides can be treated with water before consuming.

Therefore, many very active insecticides used in the plant sector do not even show the necessary effect even after the intended use for plants after a certain experimental period, so that post-treatments may be necessary, depending on the individual case. As far as possible, most insecticides, e.g. in the form of solutions, emulsions, spray concentrates and the like, also do not penetrate deeply into the plant parts, but only exert their effect on the surface, where after a certain period they are rinsed or decomposed. The systemic insecticides, on the other hand, penetrate into the plant parts, however they degrade there over a certain period of time, e.g. within 3 weeks. Also, the powdered insecticides in the form of powders often show poor adhesion and are easily rinsed.

Furthermore, a selective effect is often required in most insecticides; thus, e.g. utility animals such as bees, birds and the like are not endangered. This means that many insecticides can only be used with good results in connection with certain harmful organisms, e.g. against mites and the like, while not frequently producing the desired effect on other insects. Therefore, within the scope of the present invention, numerous insecticides were investigated for their suitability in tree preservatives, which found that even numerous highly active insecticides with a broad spectrum of insecticidal efficacy, e.g. insecticidal phosphoric acid esters and the like, were not suitable for use in wood preservatives.

For wood preservatives, claims are made that differ significantly from the requirements imposed on insecticides as means for controlling harmful organisms in their usual fields of application, e.g. for plant protection. While the insecticides, e.g. In case of plant protection, after a certain period of time must be broken down, washed out and the like, the preservative requires a long-term effect. The wood preservative must not only adhere to the surface and immediately kill the animals that come in contact with it, but must penetrate as deep into the tree as possible and protect the tree from a subsequent attack. Even under the influence of weather and wind, no significant loss of activity should occur, nor any significant reduction in the preservative effect of the wood preservative. Since the tree or tree products can not only be attacked and destroyed by numerous tree-damaging organisms, insects or their larvae and the like, but also threatened by vegetable-destroying organisms (fungi and the like), the active wood preservative must also exhibit a similar fungicidal effect, It is important that the activity of the insecticidal agent used is not adversely affected by the fungicidal agent or vice versa.

Known agents of the kind set forth in the preamble of claim 1 comprise oil-soluble insecticides, e.g. chloro naphthalene in oil-soluble or oily solvents, e.g. aromatics, as well as oil-soluble fungicides, e.g. pentachlorophenol. When using chloraphenaphthal, an unpleasant odor occurs. In addition, chlor naphthalene exhibits poor compatibility with other compounds to be used in wood preservatives. Finally, it is necessary to use large amounts of chlorophthalene in wood preservatives. Due to the toxic contaminants present in the technical chlorophthalene, there is also - depending on its concentration - the danger of warm-blooded creatures. Attempts have been made to replace chlornaphthalene with other insecticides. However, these other insecticides have been found not to be suitable for tree protection purposes or to cause other disadvantages.

It is thus the object of the invention to provide a highly active agent of the kind set forth in the preamble of claim 1, which also exhibits, after a long period of time, a sufficient insecticide and fungicidal wood protection effect which continuously protects the wood or the wood products (without to degrade these or their quality), which, even after exposure to weather and wind and the like, i.e. under the influence of rain, snow, frost and sun, will exhibit a sufficient preservative effect which is applicable both to the preservation of wood with a very good fungicide and insecticide long-term effect and as a wood-based primer or as a wood-protected color or laser-ironing agent; which can penetrate deep into the tree or into the wood products and in connection with the fact that the insecticide component used does not exhibit the disadvantages associated with the known wood preservatives which contain, as insecticide component, the chlorophenaphthalene.

The agent according to the invention, which is of the kind set forth in the preamble of claim 1, is characterized by that specified in the characterizing part of claim 1. The object of the invention is thus fulfilled.

Thus, the composition of the invention contains more than 64% by weight of a volatile, oily or oily organic solvent having an evaporation rate above 35 and a flash point above 30 ° C, and certain weight amounts of an insecticide mixture, an alkoxy-phenyl-N-alkyl carbamate. and / or alkylphenyl N-alkylcarbamate and at least one halogenated or halogen group-free thiophosphoric acid ester and / or insecticide thionophosphoric acid ester and a fungicide.

A particularly preferred embodiment of the preservative according to the invention is characterized by the characterizing part of claim 2.

A particularly preferred embodiment of the preservative according to the invention is characterized by the characterizing part of claim 3.

As fungicides known per se, soluble fungicides in the indicated amounts are known in the organic, volatile, oily or as oils solvents. Preferably, as a fungicide, a fungicidal chlorophenol, preferably penta- and / or tetrachlorophenol, or a fungicide, tetravalent tin-inorganic compound or a 1-trityl-1,2,4-triazole of the general formula N

Although numerous insecticides with a broad spectrum of action, e.g. 0,0-Diethyl-O - [(2-isopropyl-4-methyl) -6-pyrimidyl] thionophosphate, 0.0-dimethyl-2,2,2-dichlorovinyl phosphate, diethylvinylphosphate and bis (dimethylamino) phosphoryl fluoride , is not suitable for use in wood preservatives in the pre-test, because the activity thereof, after a certain test duration, is considerably poorer than desired, it could be determined within the scope of the invention that using a combination of insecticidal alkoxy-phenyl-N-alkyl carbamate and / or alkylphenyl N-alkylcarbamate and at least one insecticide halogenated or halogen group-free thiophosphoric acid ester or insecticide thionophosphoric acid ester or insecticide thionophosphonic acid ester achieved a sustained activity of the wood preservative with an activity increase, thereby preventing an active state of formicidal activity, insecticidal action. The wood preservative penetrates well into the wood and the wood product, so that there is some depth preservation and waterproofing. In the open-air experiments, it was further found that the preservative remained active even after prolonged exposure to wind and weather, and retained both its wood-protecting fungicidal and insecticidal properties, without being able to detect wood-damaging effects.

As stated, it is possible according to the invention to replace 0.5 to 20% by weight, preferably 2 to 15% by weight of the organic, volatile, oily or solvent-present solvent or solvent mixture having an evaporation number above 35 and a flash point above 30 ° C with the same amount of one or more organic-chemical binders and / or fixing agents, using as organic-chemical binders and / or fixing agents which are advantageous in the oily or as oil solvents or solvent mixtures or emulsifiable, but preferably soluble,

As a binder, in a particularly preferred embodiment, a resin is used in the form of an emulsion, dispersion or solution, preferably an alkyd resin or modified alkyd resin or a phenolic resin and / or intra-cumarone resin.

As a binder, bitumen or bituminous substances can also be used in an amount of up to 10 weight Si. Further, dyes, pigments, water repellents, odor correcting agents and inhibitors or corrosion protection agents and the like may be used per se. As water repellents, paraffins, waxes, wool grease and the like are used in weight amounts of 0.2 to 5 weight-0, preferably 0.5 to 2 weight-weight, calculated in relation to the wood preservative.

Above all, such as a fixative or plasticizer are used such compounds which must further prevent evaporation of the active substances and / or crystallization or precipitation. Preferably a) plasticizers, e.g. alkyl, aryl or aralkyl phthalates, preferably dibutyl, dioctyl and benzylbutyl phthalates, alkyl phosphates or phosphoric acid esters, preferably tributyl phosphate, adipates, preferably di- (2-ethylhexyl) adipate, stearates and oleates, e.g. alkyl stearates or alkyl olates, preferably butyl oleate, butyl stearate or amyl stearate, bis (dimethylbenzyl) ether, p-toluene sulfonic acid ethyl ester, glycerol esters, glycerol ethers or high molecular weight glycol ethers and / or b) oils, e.g. flaxseed oil, castor oil, tall oil and their esters and / or c) ketone and / or polyvinyl alkyl ether fixing agents, e.g. ketones having alkyl, aryl or aralkyl groups, preferably benzophenone, ethylbenzophenone; polyvinylalkyl ethers, preferably polyvinylmethyl ether.

As organic, volatile, oily or as oils solvents having an evaporation number above 35 and a flash point above 30 ° C, preferably above 45 ° C, water-insoluble or hardly water-soluble solvents are preferably used. As such solvents, similar mineral oils or their aromatics fractions or mineral oil-containing solvent mixtures are used, preferably test gasoline, petroleum, gas oil and / or alkylbenzene, etc.

Preferably, mineral oils having a boiling range of 170-220 ° C, test gasoline having a boiling range of 170 - 220 ° C, spindle oil having a boiling range of 250 - 350 ° C, petroleum or aromatics having a boiling range of 160 - 280 DC, turpentine oil and similar.

In one embodiment, also high boiling mixtures of aromatic or aliphatic hydrocarbons having a boiling range of 180 to approx. 220 ° C and / or spindle oil and / or monochloronaphthalene, preferably α-monochloronaphthalene.

The organic, volatile, oily or oil solvents having an evaporation number above 35 and a flash point above 30 DC, preferably above 45 ° C, may be partially replaced by light or medium volatile organic solvents, provided that the solvent mixture also exhibits an evaporation rate. above 35 and a flash point above 30 ° C, preferably above 45 ° C, and that the insecticide and fungicide mixture is soluble in this solvent mixture. In this way, the insecticide and fungicide mixture should be at least as soluble as in the previously mentioned oily or as oils solvents. It was found that, depending on evaporation rate and flash point, the organic, volatile, oily or as an oil solvent of the oily or flash solvent used was present in an amount of up to 20% by weight, preferably up to 15% by weight, may be replaced by a solvent having a lower evaporation rate.

With regard to the fungicidal active substances, it has been found that, depending on the nature of the fungicide, these can be used in different concentrations. As particularly advantageous in terms of the fungicidal effect, the use of 3 to 8% by weight of chlorophenol, preferably penta- and / or tetrachlorophenol, was found to be. Surprisingly, it has been found that the tetravalent, fungicidal, tin-organic compounds and the fungicidal 1-trityl-1,2,4-triazoles give the tree preservative an excellent good fungicidal effect, already at concentrations of 0.3 to 2% by weight. It is therefore preferable, in connection with the wood preservative as fungicide, to use 0.3-2 weight- 0

of a fungicide, tetravalent, tin-inorganic compound and / or 1-trityl-1,2,4-triazoles of general formula I

Wherein R is a fluorine, chlorine or bromine atom, a trifluoromethyl, nitro or cyano group or an alkyl group of up to 4 carbon atoms and n means the numbers 1 or 2, and their salts of organic acids , preferably trifluoromethyl-triphenylmethyl triazole or a mixture of one or more of the aforementioned fungicides.

As tetravalent, tin-organic compounds, the fungicidal, tetravalent, tin-organic compounds known per se can be used. It was found that the following tetravalent tin-inorganic fungicidal compounds were particularly suitable in the wood preservative of the invention: bis- (tri-butyltin) oxide, tri-n-butyltin trichloro-acetate, tri-n-butyltin-8-oxyquinoline, tri -n-butyltin pentachloro-phenolate, tri-n-butyltinbenzoylcyanoacetic acid, tri-n-butyltinemethytarenoic acid, tri-n-butyltin fluoride, tri-n-butyltinrhodanide, tributyltin dichlorophenolate

However, instead of these preferably useful fungicides within the scope of the invention, other fungicides which are soluble in the organic, volatile, oily or as an oil solvent having an evaporation number above 35 and a flash point above 30 may be used. ° C, preferably above 45 ° C, or mixtures thereof with the aforementioned fungicides, e.g. fungicidal, oil-soluble naphthenates, preferably zinc and / or copper naphthenates; 8-oxyquinoline or their fungicidal, oil-soluble salts or derivatives, preferably phenyl mercury-8-oxyquinolate; fungicidal compounds or derivatives or mixtures of chlorophenols, preferably compounds or mixtures of penta- and / or tetrachlorophenol with volatile amines, e.g. Rosin amine; nitrophenols or nitrochlorophenols and / or nitrochlorobenzene, especially 1,2-dinitrotetrachlorobenzene; oil-soluble, fungicidal, metal-organic compounds, e.g. of copper, zinc, manganese, cobalt, chromium or mercury, e.g. in the form of caprylates, naphthenates, oleates and the like; fungicidal salts of N-nitroso-N-cyclohexylhydroxylamine, preferably the aluminum salt of N-nitroso-N-cyclohexylhydroxylamine and / or N-trichloromethylthiotetrahydrophthalimide. However, when using N-nitroso-N-cyclohexylhydroxylamine and / or the aluminum salt of N-nitroso-N-cyclohexylhydroxylamine, it must be taken into account that these fungicidal compounds are obviously only suitable for certain tree species or wood fungi. In the fungicide mixtures it is also possible to partially use tar oil distillate and / or tar oil.

According to another embodiment, the organic, volatile or oily solvent is simultaneously a fungicidal active substance, e.g. chloro naphthalene, preferably monochloro naphthalene and / or dichloro naphthalene. This exceeds the concentration of the fungicide in this exceptional case. Preferably, however, the monochloronaphthalene and / or dichloronaphthalene are not used as the sole fungicidal active substance, but together with other solvents and / or fungicides within the scope of the present invention.

Depending on the active substances and the like used, it may be appropriate to further use emulsifiers and / or wetting agents.

As to the effect of the preservative and the reduction of a corrosion, it is appropriate to use the preservative together with mandelic acid and / or benzoetriazole. In this combination, discolouration of the wood preservative in the tin containers or by the influence of the wood preservative on wood containing metal or metal parts is prevented by any possible corrosion. This corrosion protection agent is preferably used in amounts of 0.05 to 0.2% by weight.

Frequently, the preservatives are prepared in the form of concentrates which, after being transported to the site of application using organic, highly volatile, oily or oil solvents, are again diluted to the normal concentration. This makes it possible to produce highly active wood protection concentrates which can be transported cheaply.

In the preservative according to the invention for wood and wood products, the preparation of a concentrate is also particularly advantageous. In the preparation of the concentrate, the concentrations indicated naturally shift in such a way that in each case the weight amount of the insecticide mixture and of the fungicide is increased (preferably regularly), so that a dilution to the previously stated concentrations (application concentration) is possible after transport at addition of the oily or as an oil solvent.

Depending on the field of application, concentration of the active substance and the like, the amount of wood preservative applied according to the invention may be different. It generally amounts to approx. 100 to 350 g / m, preferably 150 to 200 g / m. The wood products for which the agent is used are preferably dry wood materials, particleboard, plywood, building wood, boards, boards, wood for windows, doors, floors, ceilings, formwork, fences, walls, roofs, furniture, piles and masts.

COMPARISON.5 TRIAL

Examined preservatives and methods of investigation

1% impregnating solution of (diethoxy-thiophosphoryloxyamino) -phenylacetonitrile (or 0.0-diethyl-O- (α-cyanobenzylidene-amino) thionophosphate) was prepared; (diethoxy-thiophosphoryloxy-imino) -2-chlorophenylacetonitrile and 2-isopropoxyphenyl-N-methylcarbamate in an organic solvent having an evaporation rate above 35 and a flash point above 30 ° C and a boiling range between 100 and 210 ° C. As the fixative, the impregnating agent further contains tributyl phosphate. The active substances alone and the combination of the active substances in specific weight ratios were investigated.

For the study, round filters were impregnated with the diluted impregnant and dried for 8 days. Then, small glass tubes (diameter 2 cm, height 5 cm) filled with two damp plastic foam discs (polyurethane foam) were placed on the filter. Each tube contained 50 mg of feed tree and 30 workers of Reticulitermes santonensis. The trial duration was 21 days.

The tests worked in such a way that the applied amount of 2 active substance was at one test series at 20 g / m 2 and at another at 25 g / m 2.

The comparison experiments show that, under certain mixing conditions, an effect increase of the protective agent occurs, which exceeds the additive effect of the individual substances.

Below "% dead", the mean value of the killed termites from three comparison trials is introduced. As injurious eating, a greater material destruction was referred to, whereas as hollow eating it meant only partial destruction or slight damage, e.g. damage positions upon initial inhalation of the termites without further damage. In addition, within the experiments, it was surprisingly found that the killing time of the termites in the combination was shortened in comparison with the individual constituents.
