The mixture for the production of vibroinsulation materials to protect railways and roads for motor vehicles according to the invention consists of a rubber granules, preferably with granulation of about 1-10 mm, in quantity of 90 - 50% by weight and bituminous materials modified with thermoplastic, thermoelastoplastic polymers or rubbers in quantity of 10 - 30% by weight Modified bituminous materials operate as a binder of rubber granules. In addition, the mixture may contain modifiers in the form of mineral fillers, fabrics or resins in quantity of up to 30% by weight against the weight of the total mixture. granules made of used car tyres, waste tapes and / or belts or production waste are preferably used as rubber granules. Asphalt modified with thermoplastic, thermoelastoplastic polymers or rubbers is preferably used as a modified bituminous binder. Ethylene polymers or ethylene-propylene copolymers are preferably used as thermoplastic polymers. Block copolymers of styrene-butadiene-styrene, styrene-isoprene- styrene, styrene-ethylene/butylene-styrene, styrene-ethylene/propylene-styrene are used as thermoelastoplastic polymers. Polyester or basalt fibres, natural and synthetic resins, preferably rosin, high-styrene resin, mineral fillers of different granulation, preferably quartz are used as modifiers for improving mechanical properties, rheology and hardness. |
