LATEX COMPOSITE PARTICLES COVERED BY A MINERAL PHASE COMPRISING AT LEAST ONE HYDRATED ALKALI EARTH SILICATE WHICH IS INSOLUBLE IN WATER, PREPARATIONS AND USES THEREOF

摘要

The invention relates to encapsulated composite latex particles which consist of a core comprising at least one organic polymer (latex), which are at least partially covered by one or several coats of a mineral phase comprising at least one hydrated alkali earth silicate which is insoluble in water such as water-insoluble hydrated calcium silicate or a water-insoluble hydrated magnesium silicate or one of the mixed phases thereof. The invention also relates to the use of encapsulated latex composite particles in a mineral binder composition. The invention further relates to binder compositions comprising encapsulated latex composites and to the use thereof in the building industry, civil engineering or the oil industry.
