The present invention relates to a means for preservation of wood or wood materials.

Know of a similar tool for conservation, in which as an insecticide containing carbamates, esters of phosphoric, TIF entie ORGANOTIN compounds, chlorinated phenols, triazole, N-cyclohexyl-destindex-aluminum, and N,N-dimethyl-N'-phenyl-N'-(fertilisation)-sulphonamide /1/. However, data on the mode of action of the biocide combination is unknown.

In contrast, the present invention is to develop tools for the preservation of wood and wood-based materials, which when you choose certain fungicides detects high effectiveness against fungi, changing the color of the wood and/or destroying the texture of the tree insects, and has a stabilizing characteristics of the active substances in aqueous compositions. In addition, the tool must not only penetrate the wood, but also to ensure uniform distribution of the active substance in it.

To solve this problem is proposed remedy for the protection and preservation of wood and wood-based materials, including organic fungicides, polymer binder, water and an organic solvent, which further comprises a stabilizer 2,2,4-trimethyl-1,3-pentandiol-monoisobutyrate, and as a organic fungicide mixture of 3-iodine-2-PROPYNYL-butyl-carbamate (I) or methyl-benzimidazol-2-yl carbamate (II) alpha - [2-(4-chlorophenyl)-ethyl-alpha-(1,1-dim is (II) 0,5-0,8

Fungicide (III) 0,8-1,5

Organic solvent the rest up to 100%

Additionally it can contain non-ionic surfactant and at least one insecticide selected from the group including: 1) cyano-(4-fluoro-3-phenoxyphenyl)-methyl-3-(2,2'-dichloroethenyl)-2,2'-dimethyl - cyclopropanecarboxylate; 2) ()alpha-cyano-3-phenoxy-benzyl-()-CIS, TRANS-3-(2,2'-dichlorovinyl)-2,2'-dimethylcyclopropane-carbanilate; 3) (S)-alpha-cyano-3-phenoxybenzyl (1R 3R)-3-(2,2'-dibromovinyl)-2,2'-dimethyl-cyclopropane-carboxylate and 4) 3-phenoxy-benzyl-()-CIS-TRANS-3-(2,2'-dichlorovinyl)-2,2'-dimethyl - chloroanthracene, in the amount of 0.002-0.005 wt.

In European patent application /2/ described the use of 3-iodine-2-propynylbutylcarbamate in aqueous solutions of wood protection. Experiments showed, however, that the stability of the active substance cannot be considered satisfactory as solvents, such as aromatic and aliphatic hydrocarbons, such as glycols, cause a decrease in the stability of the active substance in the presence of water. Unexpectedly it was found that the application of the recommended 2,2',4-trimethyl-1,3-pentandiol-monoisobutyrate improves stay solvents, and also provides a better distribution of these substances in preserved wood.

Used in accordance with the invention, the diluent comprises a non-polar or polar solvent or solvent mixture, preferably oily or oily volatile ingredients henicorhynchus solvent or mixture of solvents. As an example of the latter should be called aromatic and aliphatic hydrocarbons, mixtures thereof or lacquer benzine.

In accordance with the invention, as binders used alkyd resin and/or dry solvent oil, however, it is preferable to use for this purpose artificial resins based on copolymers of methyl acrylate (n-butyl acrylate copolymers, styrene)acrylic ester and/or unstable (versatals) polyvinyl.
