Stable aqueous zeolite suspensions, their fabrication process and use.

摘要

Stable aqueous zeolite suspensions containing, as stabilising agent, a copolymer consisting of at least one acrylic monomer containing a carboxyl functional group, at least one acrylic and/or vinyl monomer without a carboxyl functional group and at least one oxyalkylenated monomer containing ethylenic unsaturation and terminated by a hydrophobic fatty chain having 12 to 40 carbon atoms. Processes for the preparation of these suspensions by mixing or by reaction during the process for the manufacture of zeolites. Use of these aqueous zeolite suspensions in detergency and as sequestering agents.
