    摘要: Insulation material for construction, of the type used in floors, ceilings and walls to improve thermal and acoustic insulation, which comprises mechanically recycled polyurethane in the form of particles, one or several flame retardants and water as the binding element, all of which are mechanically mixed. Optionally latex or other bonding agents, and powdered graphite can be added.
    The invention presented affords the main advantage of allowing optimal recycling of the polyurethane that is widely used in cars and in numerous industrial applications, obtaining a safe product in the event of possible fires in buildings, that allows compliance with strict building regulations, and that also provides excellent acoustic and thermal insulation.
