WITH FIBERS REINFORCED ACRYLIC PANEL AND PROCESS FOR ITS PRODUCTION

摘要

The invention refers to with fibers reinforced acrylic panel and process for its preparation. The tehnical problem is solved in such a way that into PMMA matrix polyhedral oligomer silsesquioxane (POOS) nanoparticles are built before polymerization.For production of nanoparticles sol-gel process was used which enables the preparation of ceramic and glass like materials at room temperature. Sol-gel matrix is formed through hydrolysis and condensation reaction. POSS functionalized with metacryloxy groups were prepared from functionalized tri-alkoxysilanes (with three alkoxy groups, T silanes). In example as basic precursor 3-(trimetoyxsilyl) propylmetacrilate (MAPTMS) was used to which in adequate proportion different functionalized trialkoyxsilanes of type R1Si(OR2)3 where R1 and R2 represent organic group were admixed. From said compounds polyhedral oligomer silsesquioxanesn were prepared by sol-gel process. In presented example acrylic panel can be formed also with reinforced threads and with reinforced net .
