Material para pavimento absorbente de ruidos y procedimiento de fabricación
The invention relates to material for noise-absorbing surfacing, which comprises a mixture of two components, characterised in that: the first component (A) comprises 40-50 wt% ground SBR rubber with a particle size less than 6 mm, 38-42% ground mineral aggregate with a particle size less than 8 mm, 10-20% polyurethane resin and 3-4% glycol, the ground SBR rubber granules and the ground mineral granules being encapsulated by the polyurethane resin; and the second component (B) comprises 50-56% isocyanate and 38-45% polyether polyol. The invention also relates to a method for producing the material, which comprises: producing the first component; encapsulating the granules of ground SBR rubber and of ground mineral aggregate using the polyurethane resin by means of a mixer; and producing the second component by introducing the isocyanate and the polyether polyol into a reactor at 50-80°C.
