An acrylic glass plate for use as an opaque noise protection element in noise protection walls, the plate measuring a minimum of 2&#xd7;2 m and having a minimum thickness of 8 mm wherein threads, strips, grids or networks consisting of a material which is incompatible with the acrylic glass are integrated into the acrylic glass for binding splinters in the event of a fracture of the plate, and the plate comprises between 40 and 80 wt. % of filling materials, in relation to its total weight (calculated without integrated threads, strips, grids or networks); and a method for producing such plates.

Noise prevention plate consisting of acrylic glass

A transparent plastic pane of acrylic glass with internal plastic filaments, which largely hold together the fragments formed in the event of a break characterized in that the plastic filaments are at least partly sized. The internal filaments can be sized completely and/or partly, for example in portions. Hereby the matrix adhesion of the filaments can be adjusted to the effect that any fragments which may be formed in the event of break are largely held together by the filaments without permitting undesired detachment of the filaments during thermal stresses in the normal range of &minus;20 to 120&deg; C. The plastic panes are suitable in particular as a noise protection wall.
