Abstract

Elastyczna uszczelka w kształcie krążka, przedstawiona na rysunku; przylegająca do czołowej powierzchni zasadniczego ładunku materiału wybuchowego zaelaborowanego w amunicji, zwłaszcza wielkogabarytowej, zwłaszcza w pocisku artyleryjskim, zawierająca polibutadien zakończony grupami hydroksylowymi oraz środek utwardzający niniejszy polimer, taki jak diizocyjanian heksametylenu albo diizocyjanian toluenu albo diizocyjanian difenylometanu, charakteryzuje się tym, że składa się z (85 - 98)% części wagowych polibutadienu zakończonego grupami hydroksylowymi oraz odpowiednio z (15 - 2)% części wagowych diizocyjanianu heksametylenu albo diizocyjanianu toluenu albo diizocyjanianu difenylometanu, przy czym grubość uszczelki stanowi (0,1 - 15)% jej średnicy.Flexible disc-shaped gasket, shown in the picture; adjacent to the front surface of the main charge of the explosive defused in ammunition, especially bulky, especially in the artillery shell, containing polybutadiene terminated with hydroxyl groups and the curing agent of the present polymer, such as hexamethylene diisocyanate or toluene diisocyanate or diphenylethylated diisocyanate, (85-98)% by weight of hydroxyl terminated polybutadiene and (15-2)% by weight of hexamethylene diisocyanate or toluene diisocyanate or diphenylmethane diisocyanate, respectively, the thickness of the seal being (0.1-15)% of its diameter.
