Title of the invention

Wirkstoffgeraisoh for the hydrophobing of wood

Field of application of the invention

The invention relates to an active substance mixture for hydrophobizing materials made of wood, in particular those which are exposed to the weather.

Characteristic of the known technical solutions

According to DD-WP 129 536 impregnating oils for sealing components made of wood are known. These impregnating oils consist of a combination of 6o to 95 Ma .- $ resin oil, with a boiling range of 11o to 38o ⁰ C, a density at 2o ⁰ C of o, 9o to 1.1 o g / vmr and a viscosity at 2o ⁰ C from 2o to 5o cSt and 5 to 4o Ma .- $ of a mineral oil product with a boiling range above 3oo ⁰ Co If necessary, they may contain up to 2o Ma, - $ bitumen solution.

This impregnating oil is characterized by its good protective effect, which consists in deep binding into the wood, sealing the surface and simultaneous hydrophobing. By adding special active ingredients, an increased protective effect against animal wood pests and fungal infestation can be achieved.

.2. MP 382

Organic wood preservatives such as Kombinaii and the like, which contain active ingredients against wood pests and fungal attack, are costly or not available in sufficient quantities. Moreover, they have strong-toxic effects and do not have sufficient hydrophobizing effects. ,

Object of the invention

The aim of the invention is an active ingredient mixture for treating materials made of wood, which in addition to a good protection against the ingress of moisture, water and aqueous solutions, a good resistance to wood pests land fungal infection is achieved. For the preparation of the active ingredient mixture available at any time and cost raw materials are used.

Explanation of the essence of the invention

The known impregnating and wood preservatives either contain substances which have a hydrophobic effect and seal the surface or active substances which protect against wood pests and fungal infestation. The special active ingredients against wood damage and fungal HoIz protective agents are costly, not available in sufficient quantities and severely harmful to health. The object of the invention is to provide a drug mixture for hydrophobizing materials made of wood, that exceeds the protective effect of known hydrophobing oils, with increased protection against wood damage and fungal infection is ensured by targeted addition of selected active ingredients, without adversely affecting the hydrophobing effect.

meet all requirements to waterproof materials made of wood, with simultaneous increased protection against wood pests and fungal infestation.

Petroleum vacuum distillates or their processing products such as, for example, extractable oils are particularly suitable as mineral oil product.

The phenols can be used as phenol, cresols or xylenols, individually or as a mixture, as part of the active substance mixture, the proportion of the individual phenol components in the mixture being of secondary importance.

By adding bitumen or bitumen solutions, the active ingredient mixtures can be adjusted to any brown to black shade »

Exemplary embodiments 3o

The invention will be explained in more detail below with reference to some embodiments:

example 1

For the preparation of 1oo kg of active ingredient mixture is a solution of 3o kg of di- and polyterpenes, 2 kg of glycerol, o, 5 kg of acrolein and o, 5 kg of formaldehyde in 2o kg of butanol and 7 kg

Submitted terpenes. S are under intensive Ruhr 3o kg 'eines'Erdölvakuumdestillates added slowly with a boiling point of 32o C ^0. This homogeneous basic solution further 7 kg of phenol and 3 kg of butyl acetate were added · 5

Example 2

The homogeneous base solution according to Example 1, a mixture of 9 kg Kr es oil and 1 kg Tr'ikresylphosphat added.

to Example 3 -

The homogeneous base solution according to Example 1 is mixed with 3 »5 kg of phenol, 1.5 kg of butyl acetate, 4.5 kg of cresol and o, 5 kg of iricresyl phosphate.

The advantages of the active ingredient mixture according to the invention for hydrophobing wood are that

the active substances used for the preparation need not have a particular degree of purity and are therefore inexpensive,.

the woods treated with the active substance mixture are sufficiently protected against the binding of water, against wood pests and fungal infestation,

- the treated woods retain their natural color and masation,

- the active substance mixtures can be easily applied to the wood by brushing, spraying and watering,

- the active substance mixtures form stable solutions and remain homogeneous even after prolonged storage,

- the specific consumption is low, - they provide several years of protection,

- no detachment of the active ingredients from the impregnated wood takes place even after prolonged exposure to water,

- good recoatability with oil and paint colors exists.
