DK 162145 B

The present invention relates to a wood preservative concentrate and a wood preservative and wood preparation thereof, which consists of predetermined parts by weight of a non-vaporizable solvent (mixture), a water insoluble insecticide (mixture) and / or a water insoluble fungicide (mixture). ), a nonionic emulsifier (blend) and a water-soluble cationic wetting agent (blend and optionally water).

A wood preservative is already known which is prepared from a liquid concentrate whose active ingredients are water-insoluble insecticides and fungicides dissolved in a solvent and in oils with the addition of such emulsifiers that the finished wood preservative is present as a thin liquid. emulsion see (DE-OS 15 25 18 416). As fungicides in this wood preservative, caprylates and naphthenates of heavy metals are preferably used.

Wood preservatives as described in DE-OS 25 18 416 present the disadvantage that with the addition of water, a milky emulsion is formed which, after a certain period of time, forms an upper layer and therefore does not present an even distribution of the active ingredients. In several cases a precipitate can be seen. Therefore, in these cases, no good impregnation occurs. In that specification, the quantities of the various constituents used are nowhere stated. Even when using large amounts of emulsifier, no optically clear emulsion or solution is obtained by dilution with water.

The present invention is intended to provide a wood preservative where these drawbacks are avoided and where the organic-chemical water-insoluble solvent, which preferably consists of a base of petroleum products, aromatics and the like, can be diluted to a significant percentage of water so that the organic-chemical solvent can be extensively saved or

2 is reduced in quantity. A blend or precipitate should be avoided almost completely when reprocessing the wood preservative. Finally, the wood preservative must exhibit good activity. In the form of the concentrate, it should be storage stable, easy to transport and easily diluted at the point of application to suitable ready-to-use concentrations by simple addition of water. By means of the content of certain weight amounts and tuned weight ratios and the composition, the finished water-thinning wood preservative must exhibit as great a depth of penetration in the wood as possible.

It has now been found that a wood preservative concentrate and an agent prepared therefrom for preserving wood and wood materials can solve these tasks when the concentrate 15 consists of an emulsion or solution of I. 5-50, preferably 10-35 parts by weight a) of a not easily evaporable organic-chemical water-insoluble solvent (mixture) with a flash point

b) of a water-insoluble insecticide (mixture) of a carbamate, a phosphoric acid ester, a thionophosphoric acid ester, a chlorinated hydrocarbon, a pyrethroid and / or of endosulfan and / or a water-insoluble fungicide (mixture) of a tetravalent organotin compound , an ester of a chlorinated phenol, a 1-trityl-1,2,4-triazole of the general formula

The present wood preservative concentrate may be anhydrous or exhibit an additional amount of water, depending on the place of application, area of application and the like. Due to the reduction in transport costs, preferably an anhydrous wood preservative concentrate or only a small amount of water is used in the wood preservative concentrate. The present wood preservative concentrate offers the advantage that a ready-to-use wood preservative can be prepared from the concentrate by dilution with water, wherein the water-insoluble solvent, preferably consisting of mineral oil and aromatics fractions or mineral oil-containing solvent mixtures such as test gasoline and / or alkylbenzene, can be significantly diluted. by adding water. In this way, the part of the organic-chemical oil-based solvent is significantly saved and reduced. Finally, a blend or precipitate is avoided both in the wood preservative concentrate and also in the ready-to-use wood preservative and in the actual processing thereof.

As water-soluble wetting agents or solvents or wetting agent mixture or solvent mixing agent is used a fungicidal arylalkyl-ammonium compound, preferably a trialkylarylalkylammonium compound and / or a fungicidal tertiary amine salt, with the above-mentioned combination of components and the aforementioned weight ratio is obtained that the preservative in the visible light-wave region is an optically clear emulsion or is almost completely dissolved.

In a preferred embodiment, the weight ratio of the ionic cationic wetting agent or wetting agent composition to the non-ionic emulsifier or emulsifier mixture is 1:20 to 20: 1, preferably 1: 5 to 5: 1.

In this embodiment, in combination with the present wetting agent, it succeeds that, even with water dilution, the preservative is dissolved into an optically clear emulsion or almost clearly dissolved in the visible light waveguide.

Of course, the wetting agent emulsifier mixture will favor the penetration depth.

As an organic-chemical solvent, an organic-chemical volatile solvent or solvent mixture having a flash point above 35 ° C is used, preferably a flash point above 55 ° C.

Advantageously, water-insoluble or hardly water-soluble solvents are used as organic volatile, oily or oil-like solvents having an evaporation number above 35 and a flash point above 35 ° C, preferably above 55 ° C. As such solvents, mineral oils or aromatics fractions thereof or mineral oil may be used.

6 containing solvents, preferably test gasoline and / or alkyl benzenes. However, by the addition of a significant water content, the content of such petroleum products in the finished wood preservative is significantly lowered.

In one embodiment, the organic-chemically volatile solvent is partially replaced by one or more water-insoluble solvents, preferably by one or more synthetic solvents and / or plasticizers. This embodiment has the advantage that the solvent content can be further lowered.

According to a further embodiment, (by weight of 100% by weight of the organic-chemical volatile solvent used) is replaced by 90% by weight, preferably up to 40% by weight of the organic-chemical volatile solvent or solvent mixture of a plasticizer used as a solvent or plasticizer mixture.

For certain applications, it is appropriate to add the concentrate or wood preservative corrosion inhibitors. Preferably, mandelic acid and / or benzotriazole are used as corrosion inhibitors in the agent. Further, it may also be appropriate to add anti-foaming agents such as silicone foam dampers or alkyl phosphates, preferably tri-n-butyl phosphate.

To prepare the ready-to-use wood preservative 15, each portion of the concentrate is diluted with 3 to 20 parts by weight of water, preferably 4 to 9 parts by weight of water. By means of this relatively high degree of dilution, in this way, the portion of the organic solvent, which consists preferably of petroleum base, mineral oil and the like, is considerably reduced, thereby saving these petroleum products. Despite the concomitant use of oily or oil-like solvents and the water-insoluble active constituents, an optically clear emulsion is obtained in the visible light-wave region, so that the ready-to-use wood preservative also appears almost clearly dissolved.

The wood fungicide prepared from the wood preservative concentrate for preserving wood and wood materials is peculiar in that it consists of 0.35 to 10% by weight, preferably 1 to 7% by weight, of one or more in an organic-chemical, highly vaporizable solvent with a flash point above 35 ° C soluble or partially soluble fungicide and / or 0.3 to 7% by weight, preferably 0.5 to 4% by weight, of at least one in an organic-chemical, heavy evaporative solvent having a flash point above 35 ° C
