Abstract

PURPOSE: To prepare the titled composition giving a cured product having excellent flame-retardance, electrical insulation, water-resistance, heat-resistance, etc., by compounding hydrated alumina, etc. to a liquid rubber composed of hydrogenated polyhydroxybutadiene polymer, an isocyanate compound, etc.
CONSTITUTION: (A) 100pts.wt. of hydrogenated polyhydroxybutadiene polymer is compounded with (B) 5W40pts.wt. of a bishydroxy compound of formula I (R is 2W4C alkyl), (C) 60W150pts.wt. of hydrated alumina, (D) 5W50pts.wt. of magnesium hydroxide, and (E) a curing agent comprising an isocyanate compound of formula II (R1WR3 are lower alkyl; n is 1W4). The amount of the component (E) is pref. 0.9W1.8 equivalent as the isocyanate group based on 1 equivalent of the hydroxyl group in the components (A) and (B).
EFFECT: It can be applied to any electrical apparatus by vacuum casting or impregnation process without using high temperature and pressure.
