Description

Fungicidal impregnating agent against microorganisms

Technical field

The invention relates to a fungicidal impregnating agent against microorganisms on concrete, bricks, mortar and plasters as well as in and on buildings. Due to its chemical composition, the fungicidal impregnating composition according to the invention is capable of effectively controlling molds, fungi and algae, as well as preventing mold, fungi and algae attack. The essence of the chemical action of the composition according to the invention lies in the combination of the chemical-physical properties which demonstrate the novelty of the composition according to the invention.

BACKGROUND OF THE INVENTION

The current destruction of fungi and molds is based on the use of known toxic chemicals. Among these, heavy metal salts such as mercury, lead, tin and zinc salts as well as cresols, phenols, hydrogen cyanide, quaternary ammonium compounds, sulfonylpyridines, captants, triazines, thiocarbamates, etc. may be mentioned. Said substances are intended to help remove microorganisms known to cause lung, blood, liver, bone and joint disease from dwelling houses. Especially dangerous to the human body or its immune system are fungi of the genera Aspergillus, Penicillium and Rhizopus, which can lead to fatal mycoses.

SUMMARY OF THE INVENTION

The essence of the invention lies, inter alia, and in contrast to the prior art, not in the toxic chemical effect of impregnating concrete, bricks, mortar and plaster, but in using an environmentally friendly and even largely biodegradable chemical composition in which surfactants are present. they have a rather minor role in the action against microorganisms. In addition, unlike a purely chemical effect, it acts as a pest control agent not tensile, but by reducing the surface tension on the physical substrate due to the use of silicon compounds such as silicones, siliconates, silicates that sensitively disturb the humid environment of microorganisms. The choice of compounds of food-friendly metal salts, such as copper sulphate (CuSO ₄ .5 H ₂ OJ), contributes to this ecological fact, which is also essential for people and / or home residents, providing chemical-physical synergism.

The present invention relates to a fungicidal impregnating agent against microorganisms, such as fungi, fungi, algae, on concrete, bricks, mortar and plasters in and on buildings, preferably consisting of organic and inorganic silicon compounds, optionally also together with other organic substances, such as % are, for example, acrylates, surfactants of anionic or cationic origin in combination with metal salts, such as, for example, water dissolved in blue, comprising 0.1 to 80 wt. inorganic silicates,

0.1 to 70 wt. % of siliconates, 0.1 to 80 wt. % silicone emulsions or acrylate resin emulsions, 0.1 to 5 wt.

% surfactants, 0.1 to 10 wt. % copper sulfate, 0.1 to 15 wt. copper oxide and water.

Sodium or potassium silicates are preferably used as silicates, and methyl siliconate is preferably used as silicates.
