Heat-hardening reaction resin mixture for impregnating insulation of electrical equipment and for the manufacture of molding materials with and without inserts |
摘要 |
A heat-hardenable reaction resin mixture including a polyisocyanate; a polyepoxy resin and an olefinically unsaturated compound having no active hydrogen atoms. Addition complexes of tertiary amines and boron trichloride having the general formula BCl3.NR1R2R3 are used as accelerators. Polymerizate inhibitors may also be added. The mixture is very storage-stable and hardens in short times (quickly) at elevated temperatures. The molding materials obtained in this manner are highly resistant to thermal aging.
