Description

The present invention relates to an agent for preserving wood and wood-based materials using oil-soluble or organic-chemical insecticides and fungicides and non-volatile solvents which are soluble in oil-like solvents.

The agent according to the invention contains certain amounts by weight of an insecticide mixture of at least one alkoxy-phenyl-N-alkylcarbamate and / or alkylphenyl-N-alkylcarbamate and at least one halogenated or halogen-free insecticidal thionophosphoric acid ester or thionophosphonic acid ester and a fungicide and more than 64 percent by weight of a non-volatile, oily or oily, organic chemical solvent with an evaporation number above 35 and a flash point above 30 30 ° C.

The flash point mentioned and the evaporation numbers given below were determined in accordance with DIN 51 755 and DIN 53 170.

It is already known that numerous carbamates and thio-phosphoric acid esters have good insecticidal activity. These compounds are therefore mainly used as pesticides, crop protection agents (see, inter alia, DT-PS 1 137 895), as spraying agents and the like for the direct or indirect control of insect pests. As a crop protection agent for these insecticides, there is often a need and requirement that they should be broken down after a certain time so that there is no damage to humans or animals when eating. It is also desirable that these insecticides on the plants can be washed off with water so that vegetables and fruit which have been treated with these insecticides can be treated by rinsing with water before consumption.

Numerous very effective insecticides used in the plant sector therefore no longer have the required effect even after the intended use on plants after a certain test period, so that aftertreatments may be necessary depending on the individual case. If possible, most insecticides, e.g. in the form of solutions, emulsions, spray concentrates and the like, do not penetrate deep into the plant parts, but only ignite their effect on the surface, where they are rinsed off or broken down after a certain time. On the other hand, the systemic insecticides penetrate the parts of the plant, but are there in a certain time, e.g. within 60 of 3 weeks, dismantled. The powdered insecticides in the form of dusting agents often have low adhesive strength and are easily rinsed off.

In addition, most insecticides often have a selective effect requirement; for example useful 65 animals such as bees, birds and the like are not endangered. As a result, many insecticides can only be used successfully against certain pests,

e.g. against mites and the like, while they often do not have any effect on other insects. Within the scope of the present invention, numerous insecticides were therefore checked for their suitability in wood preservatives, it being found that even numerous highly effective insecticides with a broad spectrum of insecticides, e.g. Insecticidal phosphoric acid esters and the like are not suitable for use in wood preservatives.

The wood preservatives are made of requirements that are different from those of the insecticides in their usual areas of application, e.g. in plant protection, as pesticides and the like vary considerably. While the insecticides, e.g. in crop protection, degraded after a certain time, washed out and the like, the preservative is required to have a long-term effect. The wood preservative should not only adhere to the surface and immediately kill the animals that come into contact with it, but should penetrate as deep as possible into the wood and protect the wood against later infestation. Even with weathering, there must be no significant loss of effectiveness and no significant reduction in the preservative effect of the wood preservative. Since the wood or the wood-based materials can not only be attacked and destroyed by numerous wood pests, insects or their larvae and the like, but are also threatened by plant destroyers (fungi and the like), the effective wood preservative must also have a corresponding fungicidal action, it is important that the effectiveness of the insecticidal agent used is not impaired by the fungicidal agent or vice versa.

The aim and object of the present invention was therefore to find a highly effective wood preservative which has a sufficient insecticidal and fungicidal wood protection effect even after a long period of time and which permanently protects the wood or the wood-based materials (without deteriorating their quality). The wood preservative should also after weathering and the like, i.e. under the influence of rain, snow, frost and sun, have a sufficient preservative effect. The agent is intended both for the preservation of wood with a very good fungicidal and insecticidal long-term effect and as a wood-protecting primer or as a wood-protecting paint or Glaze paint can be used and can penetrate well into wood or wood-based materials.

The agent according to the invention is now characterized in that the preservative contains 0.5-7% by weight, preferably 2-5% by weight of a component A, consisting of at least one in an organic chemical, low volatility, oily or oily solvent with a Evaporation number above 35 and a flash point above 30 ° C soluble insecticidal alkoxy-phenyl-N-alkyl carbamate and / or alkylphenyl-N-alkyl carbamate and at least one in an organic chemical, non-volatile, oily or oily solvent with an evaporation number above 35 and a flash point above 30 ° C soluble insecticidal halogenated or halogen group-free thionophosphoric acid esters or thionophosphonic acid esters of the general formula

Although numerous preliminary insecticides with a broad spectrum of activity, e.g. 0.0-diethyl-0 - [(2-isopropyl-4-methyl) -6-pyrimidyl] thionophosphate, 0.0-dimethyl-0-2,2-dichlorovinyl-phosphate, diethyl vinyl phosphate and bis (di- methylamino) -phosphoryl fluoride etc. are not suitable for use in wood preservatives, since their effectiveness wears off to a considerable extent after a certain test period, it was found in the context of the invention that when using a combination of insecticidal alkoxy-phenyl-N-alkylcarbamate and / or alkylphenyl-N-alkyl carbamate and at least one insecticidal halogenated or halogen group-free thionophosphoric acid ester or thionophosphonic acid ester, the wood preservative has a long-term effectiveness with an increase in activity, although it was not possible to determine the effectiveness of the insecticidal activity when adding fungicidal active ingredients. The wood preservative penetrates well into the wood and the wood-based materials, so that there is also a certain deep preservation and impregnation. In the tests carried out outdoors, it was also found that the preservative remained effective even after prolonged weathering and retained both its wood-protecting fungicidal and insecticidal properties, without it being possible to determine any wood-damaging effects.

In the agent according to the invention, 0.5-20% by weight, preferably 2-15% by weight, of the organic-chemical, low-volatility, oily or oily solvent or solvent mixture with an evaporation number above 35 and a flash point above 30 ° C. by the the same amount of one or more organic chemical binders and / or fixatives may be replaced, the organic chemical binders and / or fixatives used being those which are dispersible or emulsifiable, but preferably soluble, in the oily or oily solvent or solvent mixture.

In a particularly expedient embodiment, synthetic resin in the form of an emulsion, dispersion or solution, preferably alkyd resin or modified alkyd resins or phenolic resin and / or indene-coumarone resins, is used as the binder. Bitumen or bituminous substances of up to 10% by weight can also be used as binders. In addition, known dyes, pigments, water-repellants, odor correctors and inhibitors or anticorrosive agents and the like can be used. In particular, paraffins, waxes, wool grease and the like are used as water-repellent agents in amounts by weight of 0.2 to 5% by weight, preferably 0.5 to 2% by weight, based on the wood preservative.

As fixatives or plasticizers, especially those compounds are used which are also intended to prevent volatilization of the active substances and / or crystallization or precipitation. Preferably a) plasticizers, e.g. Alkyl, aryl or aralkyl phthalates, preferably dibutyl, dioctyl and benzyl butyl 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 oleates, preferably butyl oleate, butyl stearate or amyl stearate, bis (dimethylbenzyl) ether, ethyl p-toluenesulfonate, glyceryl ester, glycerol ether or higher molecular weight glycol ether and / or b) oils, e.g. Linseed oil, castor oil, tall oil and their esters and / or c) fixatives based on ketones and / or

Poly vinyl alkyl ethers, e.g. Ketones with alkyl, aryl or aralkyl groups, preferably benzophenone, ethylbenzophenone; Polyvinyl alkyl ether, preferably polyvinyl methyl ether, used.

5 Advantageously, water-insoluble or hardly water-soluble solvents are used as organic, non-volatile oily or oil-like solvents with an evaporation number above 35 and a flash point above 30 ° C., preferably above 45 ° C. Appropriate mineral oils or their aromatic fractions or mineral oil-containing solvent mixtures, preferably white spirit, petroleum, gas oil and / or alkylbenzene etc. are used as such solvents.

Mineral oils with a boiling range 15 of 170-220 ° C, white spirit with a boiling range of 170-220 ° C, spindle oil with a boiling range of 250-350 ° C, petroleum or aromatics with a boiling range of 160-280 ° C, turpentine oil and preferably the like used.

In one embodiment, high-boiling mixtures of aromatic and aliphatic hydrocarbons with a boiling range from 180 to about 220 ° C. and / or spindle oil and / or monochloronaphthalene, preferably a-monochloronaphthalene, were also used.

The organic low-volatility oily or oily solvents with an evaporation number above 35 and a flash point above 30 ° C., preferably above 45 ° C., can be partially replaced by volatile or medium-volatile organic chemical solvents, with the proviso that the solvent mixture also has an evaporation 30 number above 35 and a flash point above 30 ° C, preferably above 45 ° C, and that the insecticide-fungicide mixture is soluble in this solvent mixture. The insecticide-fungicide mixture should be at least as soluble as in the aforementioned oily or oily solvents. It was found that, depending on the evaporation number and flash point of the oily or oily solvent used, the organic low-volatility oily or oily solvent up to 20% by weight, preferably up to 5% by weight, is replaced by a solvent with a lower evaporation number can.

With regard to the fungicidal active ingredients, it has been found that these can be used in different concentrations depending on the type of fungicide. The use of 3-8 45% by weight ghlorphenol, preferably penta- and / or tetrachlorophenol, was found to be particularly advantageous with regard to the fungicidal action. Surprisingly, it was found that the tetravalent, fungicidal, organotin compounds and the fungicidal 1-trity 1-1,2,4-triazoles give the wood preservative a very good fungicidal action even in concentrations of 0.3-2% by weight. Thus, within the wood preservative, preference is given to 0.3-2 percent by weight of a fungicidal, tetravalent, organotin compound and / or l-trityl-l, 2,4-triazole of the general formula I as fungicide

The comparative experiments show that, if certain mixing ratios are observed, the effectiveness of the protective agent increases, which even goes beyond the additive effect of the individual substances.

The average of 30 termites killed from 3 comparative experiments is entered under “% dead”. A higher level of material destruction was designated as pitting, whereas pitting is understood to mean only partial destruction or minor damage, e.g. Damage caused by the termites beginning to eat in without extensive damage. Within 35 of the experiments, it was also surprisingly found that the kill time for the termites in combination is reduced compared to the individual components.
