Abstract
A water-dilutable wood preservative concentrate which does not require a substantial amount of petroleum derived solvent comprises, by weight, from 80 to 95% of at least one water-soluble inorganic salt which preferably has fungicidal and/or insecticidal and/or wood preservative properties and is substantially free from hexavalent chromium compounds, and from 20 to 5% of an insecticidal concentrate which can be emulsified in water. The insecticidal concentrate comprises, by weight, from 01 to 30 parts of at least one organic, water-insoluble insecticide, preferably a contact insecticide, from 20 to 60 parts of at least one organic water-insoluble solvent which may be an oil of low volatility and/or a plasticiser, and from 20 to 70 parts of at least one non-ionic emulsifier. The wood preservative concentrate can be diluted with water in the proportions of 5 to 15 parts by weight of concentrate to 95 to 85 parts by weight of water to form an aqueous solution, emulsion or dispersion which can be used to preserve wood by coating, impregnation and other methods. A process for making the concentrate is described by treating insecticide, and solvent at a temperature of 0 to 80 DEG C., and under a pressure of 0.5332 to 1.332 bars until a solution is formed. The solution is combined with the emulsifier at a temperature below 50 DEG C., and the resulting mixture is added to the inorganic salt.
Description
SPECIFICATION
Wood preservative concentrate and woodpreservative impregnating liquid prepared therefrom by dilution with water
This invention relates to wood preservatives and is concerned with a wood preservative concentrate and with a wood-preserving impregnating liquid which can be prepared from the concentrate by dilution with water. The invention also relates to such an impregnating liquid and to a process for preparing the concentrate.
A wood preservative which is prepared from a liquid concentrate of which the active ingredients are water-insoluble insecticides and fungicides, which are dissolved in a solvent and in oils, with the addition of emulsifiers, in a manner such that the finished wood preservative is in the form of a mobile emulsion is known and such a preservative is described in German Offenlegungsschrift No.
2,518,416. The fungicides in this wood preservative are preferably caprylates and naphthenates of heavy metals, and other water-insoluble organic heavy metal compounds.
These wood preservatives have the disadvantage that, when water is added, a milky, turbid emulsion is formed which creams after a certain period of time and in which the active ingredients are thus not uniformly distributed. A sediment could be observed in several cases. In these cases, impregnation of the wood may not be fully effective.
It is an object of the present invention to provide a wood preservative which has a good woodpreservative action and which can be diluted with water and employed as an impregnating liquid.
Furthermore, it would be desirable to provide an agent for preserving wood in which a considerable percentage of the organic water-insoluble solvent, which is preferably based on petroleum products, aromatics and the like and which is conventionally used for dissolving organic insecticides, could be replaced by water, so that a substantial saving of organic solvent can be made, or its content can be reduced. It is desirable that a wood preservative should not separate or deposit a sediment during processing and that it should be stable on storage and transportable. Furthermore, it should be possible to dilute a concentrate of the preservative to the ready-to-use concentration by simply adding water at the location of use or at the point of distribution. It is also desirable that the preservative should contain inorganic wood-preservative salts.However, these have the disadvantage that they must be employed in relatively large amounts in order to achieve adequate protection again insects which destroy wood, since they act only as ingested poisons. By keeping within the limits of certain amounts by weight and matched weight ratios and compositions, the present wood preservative concentrate which may be diluted with water to form a ready-to-use preparation or an impregnating liquid, should as far as possible achieve a sufficient depth of penetration in the wood.
According to one aspect of the present invention there is provided a water-dilutable wood preservative concentrate, comprising, by weight, the following components:
a) 80 to 95% of at least one water-soluble inorganic salt which has fungicidal and/or insecticidal and/or wood preservative properties and which is substantially free from, or contains less than 2% of, hexavalent chromium compounds,
b) 20 to 5% of an insecticidal concentrate which can be emulsified in water and which comprises by weight:
(i) 0.1 to 30 parts of at least one organic, waterinsoluble insecticide,
(ii) 20 to 60 parts of at least one organic, waterinsoluble solvent in which said insecticide is soluble, and
(iii) 20 to 70 parts of at least one non-ionic emulsifier.
Preferably, the present concentrate comprises, by weight, from 84 to 94% of inorganic salt and 16 to 6% of insecticidal concentrate which itself preferably comprises from 0.5 to 25 parts of insecticide, desirably a contact insecticide, 35 to 45 parts of solvent and 30 to 50 parts of emulsifier.
Depending upon the location of use or field of use, the present wood preservative can be anhydrous or can contain an additional amount of water. An anhydrous wood preservative or a wood preservative in concentrated form containing only a small amount of water is preferably marketed, in orderto reduce transportation costs. The present wood preservative has the advantage that, by dilution with water, it is possible to prepare therefrom a readyto-use impregnating liquid comparable with previously proposed liquids but in which a considerable percentage of the conventionally used organic water-insoluble solvent, which preferably consists of mineral oil or aromatic fractions thereof or solvent mixtures containing mineral oil, such as white spirit and/or alkylbenzene, and which is used for dissolving the organic insecticide, can be replaced by water.
A substantial saving is thus thereby made in the amount of organic solvent based on petroleum, or this amount is thereby reduced. Finally, separation or the deposition of a sediment both in the wood preservative in concentrated form and in the readyto-use impregnating liquid, as well as during processing thereof, is largely avoided.
The inorganic fungicidal and/or inorganic insecticidal or wood-preserving water-soluble salt component may be a single salt or a mixture of salts and comprises at least one salt which contains a fluoride and/or fluosilicic acid and/or borate anion and/or a copper cation. Examples of suitable salts include magnesium silicofluoride, copper silicofluoride, ammonium silicofluoride, copper sulphate, sodium polyborate, sodium fluoride, ammonium fluoride and potassium fluoride.
The organic, water-insoluble solvent component may consist of a single solvent or a mixture of solvents and preferably has a low volatility, an evaporation number greater than 35 and a flashpoint above 50"C. Suitable examples of such solvents include mineral oils or aromatic fractions thereof or solvent mixtures containing mineral oil, preferably white spirit and/or alkylbenzenes and the like. Alternatively, the solvent or some of it may be constituted by a solubilising agent consisting of one or more plasticisers. Thus, in another embodiment of the present composition, all or some of the organic solvent with a low volatility is replaced by such a solubilizing agent. This embodiment has the advantage that the content of solvents is reduced still further or can even be saved completely.Preferably, up to 65% by weight, more preferably up to 40% by weight (based on 100% by weight of the organic solvent of low volatility employed), of the organic solvent or solvent mixture of low volatility is replaced by a plasticiser or by a mixture of plasticisers. Examples of suitable plasticisers include alkyl, aryl and aralkyl phthalates, preferably dibutyl phthalate, dioctyl phthalate and benzyl butyl phthalate; alkyl phosphates and phosphoric acid esters, preferably tributyl phosphate; adipates, preferably di - (2 ethylhexyl) adipate; stearates and oleates, for example alkyl stearates or alkyl oleates, preferably butyl oleate, butyl stearate or amyl sterate; glycerol esters; glycerol ethers or higher-molecular weight glycol ethers.
The water-insoluble organic insecticide present in the insecticidal concentrate is, as mentioned, prefer
ably a contact insecticide, and is soluble in the organic solvent. The insecticide is preferably a car
bamate, a phosphoric acid ester, a thiophosphoric acid ester, a dithiophosphoric acid ester or a thionophosphoric acid ester, a chlorinated hydrocarbon, a pyrethroid or endosulphan, or a mixture of two or more of these compounds.
The insecticidal thionophosphoric acid ester which may be used include insecticidal thionophosphoric acid esters, which are halogenated or free from halogen atoms and which have the formula
where (Hal) denotes optional halogenation, preferred esters including (diethoxy-thiophosphorylox- yimino) - phenyl - acetonitrile or 0,0 - diethyl 0 - (a cyanobenzylidene - amino) - thionophosphate, and (diethoxythiophosphoryl - oxyimino) - 2 - chlorophenylacetonitrile.
It is furthermore possible to use organic phosphoric acid esters of the general formula
where Rl is an alkyl group with 1 to 4 carbon atoms,
R2 is a saturated or unsaturated alky group with 1 to 4 carbon atoms or a group of the formula R3 -O-CH2CH2- in which R3 is an alkyl group with 1 to 4 carbon atoms, Xis a hydrogen or halogen atom, andn is 1,2 or3, orto use N - (dimethylaminomethylidene) thiol (thiono) - phosphoric acid ester-imides of the formula
in which X is an oxygen or sulphur atom, R' is an alkyl group with 1 to 6 carbon atoms and R is an alkyl, alkylenyl, alkinyl, aralkyl, alkylthioalkyl or alkylthioalkyl group.
Dieldrin, aldrin and lindance are preferably employed as the chlorinated hydrocarbons while the preferred pyrethroids include allethrin, cyclethrin, fu rethrin, tetramethrin, resmethrin, bioresmeth rin and other insecticidally active compounds of pyrethrum. The preferred carbamates include alkoxyphenyl N-alkylcarbamates of the general formula
and alkylphenyl N-alkylcarbamates of the general formula
in each ofwhich formulae R1 is an alkyl group with 1 to 4 carbon atoms, preferably a methyl group, ancrRz represents an alkyl group with 1 to 5 carbon atoms, preferably an alkyl group with 3 to 4 carbon atoms.
In a further modification of the present invention, it is possible to replace 0.01 to 100% by weight, preferably 0.1 to 50% by weight, of the water-soluble inorganic salt which has fungicidal and/or insecticidal and/or wood-preserving properties by one or more water-soluble inorganic salts having no or substantially no fungicidal and/or insecticidal properties.
Surprisingly, it has been found that, within the scope of the weight ratios and compositions indicated, the action of the organic water-insoluble insecticides, which are preferably contact insecticides, can be increased if one or more inorganic non-insecticidal or non-fungicidal salts are present.
The non-insecticidal or non-fungicidal salts used are water-soluble salts, sodium chloride, ammonium chloride, potassium chloride, sodium sulphate and magnesium sulphate being preferred salts. It has been found that the action of the salt/insecticide mixture, using the liquid, is greater than that of the salt or insecticide by itself, and that the action of the organic water-insoluble insecticide can even be increased if a salt which has no action of its own against insects is also used in the present preservative.
A preferred embodiment of the present concentrate which can be diluted with water to form a ready-to-use agent for preserving wood and timber comprise 80 to 95% by weight, preferably 84 to 94% by weight, of at least one inorganic, fungicidal and/or insecticidal water-soluble salt or mixture of salts which is free from hexavalent chromium compounds or contains these only in amounts of less than 2% by weight, and which contains at least one water-soluble salt which has a fluoride and/or fluosilicic acid and/borate anion and/or a copper cation, and 20 to 5% by weight, preferably 16 to 6% by weight, of an insecticide concentrate which can be emulsified and contains 0.1 to 30 parts by weight, preferably 0.5 to 25 parts by weight, of at least one organic water-insoluble insecticide, preferably a contact insecticide, which is soluble in the organic solvent, 20 to 60 parts by weight, preferably 35 to 45 parts by weight, of at least one organic, waterinsoluble solvent or mixture of water-insoluble solvents, consisting of one or more solvents with a low volatility, an evaporation numbergreaterthan 35 and a flashpoint above 50"C., preferably of one or more oily or oil-like, organic solvents or mixture of solvents and 20 to 70 parts by weight, preferably 30 to 50 parts by weight, of at least one nonionic emulsifier or mixture of emulsifiers.
The inorganic, fungicidal and/or insecticidal, water-soluble salts can be replaced by water-soluble salts with no fungicidal action and/or with no insecticidal action, such as sodium chloride, ammonium chloride, potassium chloride, sodium sulphate and magnesium sulphate.
If desired, the present wood preservative concentrate or the preservative agent or impregnating liquid prepared by diluting the concentrate with water may additionally contain 0.01 to 2.5 parts by weight, preferably 0.1 to 1 part by weight, of an anionic wetting agent or wetting agent mixture per 100 parts by weight of inorganic salt. If desired, the concentrate may also contain an organic dyestuff.
The anionic wetting agent is preferably empolyed when the organic dyestuff is also used. Furthermore, an anionic wetting agent is preferably also used when silicofluorides are employed.
For certain fields of use, it is expedient to add corrosion inhibitors to the concentrate or wood preservative; mandelic acid and/or benzotriazole are preferably employed as the corrosion inhibitor.
The present wood preservative concentrate can be used as it is, for example for impregnation in bandages, in bore hole fillings and the like. The wood preservative concentrate is, however, preferably diluted with water to prepare a ready-to-use wood preservative agent. The ready-to-use preservative may contain 95 to 85 part by weight, preferably 93 to 88 parts by weight, of water, per 5 to 12 parts by weight, preferably 7 to 12 parts by weight, of preservative concentrate and may be in the form of an aqueous emulsion, an aqueous emulsion/dispersion mixture or an aqueous emulsion which appears optically clear depending upon the composition.
According to another aspect of the present invention there is provided a process for the preparation of the concentrate described above, wherein the water-insoluble insecticide component, which is liquid at room temperature, is treated in the organic solvent component at a temperature of 0 C, to +80"C., and under a pressure of 400 mm. Hg to 850 mm. Hg (0.5332 to 1.1332 bars), preferably 600 mm
Hg to 790 mm. Hg (0.7999 to 1.0532 bars), until a solution is formed, and wherein this solution is combined with a liquid consisting of the non-ionic emulsifier component at a temperature below 50"C., whilst stirring, and the mixture is added to the inorganic salt component.Preferably, the treatment is effected at a temperature of 15"C., to 45 C., and under a pressure of 600 mm. Hg to 790 mm. Hg (0.7999 to 1.0532 bars), and the resulting solution is combined with the emulsifier component and, if appropriate, water at a temperature of from 15 to 45"C.
