Process for the co-encapsulation of biocidally active compounds in clay minerals functionalized by nitrogen compounds |
| 摘要 |
This invention relates to a process for the co-encapsulation of biocidally active ingredients in a clay mineral, the process comprising the step of bringing the clay mineral into contact with a biocidally active nitrogen compound that contains at least one hydrocarbon group with 6 to 20 carbon atoms, and at the same time or subsequently with at least one biocidally active compound selected from the group consisting of 2-n-octyl-4-isothiazoline-3-one, 3-iodopropenylbutyl-carbamate and tetrahis(hydroxymethyl)phosphonium sulfate. And the use of such encapsulated product in water based paints, coatings and varnishes. |

1. A process for the co-encapsulation of biocidally active ingredients in a clay mineral, wherein the process comprises the steps of bringing the clay mineral into contact with a biocidally active nitrogen compound according to formula (4)
[R1R2(CH3)2N]+X− (4) wherein R1 is benzyl, R2 is a linear C12 to C18 hydrocarbon group and X− is chloride and at the same time or subsequently bringing the clay mineral into contact with at least one biocidally active compound selected from the group consisting of 2-n-octyl-4-isothiazoline-3-one, 3-iodopropenylbutyl-carbamate, tetrakis(hydroxymethyl)-phosphonium sulfate and mixtures thereof. |
