Abstract
The invention is directed to a construction material and to the use of modified layered inorganic material. The construction material of the invention comprises a layered inorganic material, which layered inorganic material comprises an ionic organic modifier compound and a biocide. The construction material of the invention has increased resistance against microbial fouling.
Claims24
Material for construction comprising an inorganic material with plate-like structure, wherein the inorganic material is modified with one or more ionic organic modifier compounds and wherein said inorganic material is intercalated with a biocide.
Method for controlling the release profile of a specific biocide in a material for construction, comprising
- providing an inorganic material with plate-like structure;
- adjusting the affinity of the inorganic material to the specific biocide by modifying the inorganic material with one or more ionic organic modifier compounds;
- intercalating the modified inorganic material with the biocide;
- and
- including the modified and intercalated inorganic material in a material for construction.
