Humidity and volatile organic compounds storing building material mixture and clean.

[0001] The present invention describes a moisture and area Technical volatile organic compounds (VOCs) storing Building material mixture with at least one proportion of pure carbon, in particular of activated carbon and an adsorbent, moisture and volatile organic compounds (VOCs) be stored and a plaster for application to ceilings, floors and walls of interiors, wherein the adsorbent comprises activated carbon and a plaster at least a portion.[0002] State of the Art In the adsorption is the attainment of atmospheric humidity in the inner region to create a pleasant indoor climatic conditions and the resulting comfort for people. To this end were established repeatedly materials for inner surfaces, which have a high moisture quickly and may submit

Among the VOCs are all organic compounds according to World Health Organisation (substances consist primarily of carbon and hydrogen the) with boiling points in the range of 260 °C 50 °C to, with the exception of pesticides counted.

Based on activated carbon or carbonized particles Establishing a substance mixture with addition of perlite and/or diatomaceous earth, which above all for the production of plates for use in the building industry is suitable. The porous inorganic materials form an adsorbent and adsorbing capacity for moisture and VOCs to a lead, which can be used in the building industry. According to the disclosure the material mixture is effective as a constituent of plates. It be made but says nothing, whether and how the material mixture can be used alone for
