Use of nanocomposite materials to reinforce infrared, ultraviolet and visible electromagnetic radiation blocking properties in plastics

摘要

The invention relates to the use of nanocomposite materials in plastic packaging applications to reinforce their ability to protect against infrared and ultraviolet-visible radiation. This nanocomposites comprises a plastic matrix, a nanoreinforcement which is a clay and optionally an organic or hybrid substances intercalated in the laminar structure of the clay. The method for obtaining said nanocomposite comprises the following steps: reducing the size of the laminar particles by mechanical action, removal of crystalline oxides and hard particles not modified, obtaining fine laminar material or laminar structures, pre-treating the laminar structures using precursors, and adding the product of the above steps, either in the liquid state or in the dry state, to a plastic matrix.
