FIELD: construction.
SUBSTANCE: invention deals with manufacture of boards of acrylate glass used as elements of acoustic screens and relates to process and methods. The board is suggested to be fabricated of acrylate glass, the size being at least 2x2 m with a thickness no less than 8 mm; to minimise splinter dispersion at eventual formation of cracks there are fibres, straps, grids and nets embedded in the board which are made of an acrylic glass incompatible material and filler admixtures added to the acrylic glass such as: talc, dolomite, natural aggregates of talc and dolomite, mica, quartz, aluminium chlorite, oxide and/or hydroxide, loams and clays, silicium dioxide, silicates, carbonates, phosphates, sulfates, sulfides, oxides of metals, ground glass, glass balls, ceramic material, kaoline, porcelain material, christobalite, feldspar and/or chalk. The filler fraction amounts to 40-80% of the total board weight minus the weight of the fibres, straps, grids and nets embedded. There is a method also suggested for manufacture of boards above specified.
EFFECT: enhancement of the boards mechanical properties and resistance to environmental factors; minimisation of splinter formation and ignitability.
