Abstract

PURPOSE: To provide a liquid rubber composition having improved flame retardancy and excellent dielectric characteristics, useful for the insulation of electrical equipment, and composed of a liquid polybutadiene homopolymer having OH- groups at both ends of the molecule, as main component, and a flame-retardant composition comprising hydrated alumina, red phosphorus powder, a halogen compound, etc.
CONSTITUTION: A composition composed of (A) 100 parts by weight of a mixture containing (a) a liquid polybutadiene homopolymer having OH-groups at both ends of the molecule, and having a molecular weight of 2,000W5,000, and (b) a liquid diluent such as diethyl phthalate, trioctyl phosphate, etc., (B) 40W100 parts of a hydrated alumina of formula Al2O3.3H2O, (C) ≥ 5 parts, pref. 5W15 parts of red phosphorus powder, and (D) 5W20 parts of a halogen compound such as hexabromobenzene, hexabromodiphenyloxide, etc. The composition has excellent flame retardancy by the additive effect of the component (B) and the component (C).
