<p>Acrylic glass panel for use as a nontransparent noise prevention element in noise barriers, with a size of at least 2 x 2 m and a thickness of more than 8 mm, comprising an acrylic glass-incompatible material embedded in the acrylic glass in thread, strip, lattice or mesh form to bind splinters in the event of breakage, has a filler content of 40-80% by weight of the panel minus embedded material. An Independent claim is also included for production of the acrylic glass panel by preparing a filler-containing polymerizable (meth)acrylate composition, adjusting the viscosity of the composition to more than 0.1 Pa.s, pouring the composition into a mold containing the material to be embedded, polymerizing the composition above room temperature to form a panel, and removing the panel from the mold.</p> |
