Abstract

Invenţia se referă la un procedeu de obţinere a unei mase de turnare pe bază de bismaleimidă, care constă în amestecarea la o temperatură de 160...175°C a bismaleimidei cu răşină epoxidică timp de 2...8 min, adăugarea diaminei la o temperatură de 150...170°C, cu continuarea amestecării timp de 1...8 min. Se videază incinta de reacţie şi se toarnă amestecul rezultat în matriţe. Se finalizează procedeul în două etape de câte 2 h, la temperaturi de 120...140°C şi respectiv 140...160°C. Masele de turnare obţinute au aplicaţii în industria electrotehnică şi electronică.
