  1. COMPOZITIE POLIMERICA CU PROPRIETATI MAGNETICE Georgeta Andrei, Victoria Constantinescu, Mirela Moraru, Diana Cristina Andrei, Doroteia Pogorevici, Neculai Vasile Asociatia CHIMINVENT, BRAZI, tel/fax 40 244 513020, email: diritec@pbrazi ROMANIA Brevet RO 110879/1997 Obtinerea de compozite polimerice cu proprietati magnetice si mecanice bune, pe baza de elastomeri termoplastici, ferita de bariu si lubrifianti. Compozitiile polimerice cu proprietati magnetice conform inventiei prezinta caracteristici superioare de elasticitate si prelucrabilitate comparativ cu compozitiie cunoscute de acelasi tip. Principalele caracteristici ale produsului sunt prezentate in tabelul urmator: *Bloc - copolimer stiren - butadiena - stiren ** Copolimer etilena - propilena *** Copolimer etilena - propilena - diena Domenii de utilizare: Compozitiile polimerice cu proprietati magnetice se utilizeaza la obtinerea de magneti plastici pentru: garnituri pentru frigidere, motoare de putere mica, generatoare, traductoare, etc. • Compozitele prezinta proprietati mecanice si magnetice bune; • Amestecarea componentelor se realizeaza in conditii blande, fara degajare de noxe, pe utilaje folosite in industria de prelucrare a polimerilor (valt, malaxor); • Se evita vulcanizarea elastomerului pentru obtinerea proprietatilor elastice; • Se diversifica gama de elastomeri termoplastici folositi pentru obtinerea magnetilor plastici. The invention refers to a polymeric composition having magneric properties, based on 78-95% barium ferrite, 4-20% elastomer (ethylene-propylene copolymer, ethylene-propylene-diene copolymer, polyisoprenic elastomer, thermoplastic elastomer SBS), and 1-2% mixture of strearine and di-basic lead stearate. Inventia se refera la o compozitie polimerica cu proprietati magnetice constituita din 78-95% ferita de bariu, 4-20% elastomer ales dintre: copolimer etilena-propilena, copolimeri etilena-propilena-diena, cauciuc poliizoprenic, cauciuc polibutadienic sau cauciuc termoplastic SBS si 1-2% amestec stearina si stearat bibazic de plumb.
