PRODUCTION OF RESILIENT AND NOISE-ABSORBING POLYMER WITH THERMOPLASTIC MICROSPHERES

摘要

FIELD: process engineering.SUBSTANCE: invention relates to production of resilient noise-absorbing compositions based on polyurethanes and thermoplastic microspheres. Production of composition of polymer and powder filler comprises mixing of components, removal of gas inclusions and composition polymerization. Components are mixed in priming mould composed of hollow cylinder spinning about its axis. Power filler is composed of expanded microspheres used in amount of 1-2 wt % of composition weight.EFFECT: accelerated removal of gas inclusions, decreased effects of lamination.3 cl
