Abstract

Fungicidal impregnating agent for treating concrete, bricks and plaster comprises (in wt.%): 0.1-80 inorganic silicates, 0.1-70 siliconates, 0.1-80 silicone- or acrylic- resin emulsion, 0.1-5 copper oxide, 0.1-10 copper sulphate (CuSO4.5H2O), optionally 0.1-5 cationic or anionic surfactant, and water. The silicate is preferably a sodium- or potassium- silicate. The siliconate is preferably methylsiliconate.

Description

The present invention relates to a phicogenic impregnating agent against an anti-inflammatory agent microorganisms on concrete, bricks, mortar and plasters, necSofe 4i ^.

in buildings and buildings. Fungicidal impregnating agent _{from 0 zz} ί · _{M z} ~ I of the invention is due to its chemical composition -s-eiwpeTi "™"'''··' effectively destroying fungi, algae and fungi and Prevent mildew, fungi and algae. 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 control of molds and fungi is based on the use of known toxic chemicals. These include heavy metal salts, such as mercury, lead, tin and zinc, as well as cresols, phenols, hydrogen cyanide, quaternary ammonium compounds, sulfonylpyridines, captants, triazines, thiocarbamates, etc. These substances are intended to assist in the removal of microorganisms. known to cause lung, blood, liver, bone and joint disease from residential homes. Especially dangerous to the human body or its immune system are fungi of the genera Aspergillus, Penicillium and Rhizopus, which can lead to deadly mycoses.

SUMMARY OF THE INVENTION

The essence of the present invention lies inter alia and in contrast to the prior art not in the toxic chemical effect of impregnating concrete, brick, mortar and plaster, but in using an environmentally friendly and even largely biodegradable chemical composition in which surfactants are present but which they have a rather minor role in the action against microorganisms. In addition, unlike a purely chemical agent, it acts as a pest control agent not tensidically but rather to reduce the surface tension and stress on the physical substrate due to the use of silicon compounds such as silicones, silicones, silicates,

which sensitively disturbs the humid environment of microorganisms. The choice of food-friendly metal salt compounds, such as copper sulphate (CuSO 5 .5 t ^ O), contributes to this ecological fact, which is also essential for people and / or occupants of homes, thus providing chemical-physical synergism.

The present invention provides 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, blue vitriol dissolved in water, which comprises 0.1 to 80 wt. % of 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.

The silicates used are preferably sodium or potassium silicates, and the silicates are preferably methyl silicates.
