摘要

b change process of group of kaolinite clay in order to reconcile their use as reinforcing agents or mineral fillers (nano) compu00f3sitcs with organic polu00ecmeros d .The present invention relates to the processes of modification of the structure and / or morphology and / or characteristics and / or surface properties and / or interlamelares clay of the group of the kaolinite or clays containing these minerals to be these materials used in the modified Btenu00e7u00e3o of compu00e1sitos with organic polymers.The modification of these agents to strengthen or mineral fillers may alter their interactions with organic polymers, strive to use in (nano) composites. These materials thus obtained may be physical, chemical characteristics and mechanical properties of differentiated in relation to the materials to be obtained without the use of minerals or with the use of the minerals without modification.There is the possibility of significantly improving properties such as mechanical strength, resistance to gas permeability, durability, resistance to thermal degradation, among others. These composites can provide added value is much higher than the polymers of origin, being used in applications of the most diverse, including high - technology.The aggregation of value also will give the minerals modified, opening up new possibilities for marketing the raw materials taken usually as low cost.The huge national natural reserves, and high production, domestic consumption and export of clays of the group of the kaolinite confer to these processes and this invention a strategic value for the industries and mineral processing and fine chemistry and applied national.
