RESIN COMPOSITION FOR CABLE PLASTICATE Russian patent published in 2005 - IPC

FIELD: chemical technology, in particular plasticized composition based on polyvinylchloride for cable plasticate.

SUBSTANCE: claimed composition contains polyvinylchloride, dioctylphtalate, chloroparaffin, tribasic lead sulfate, calcium stearate, antimony trioxide, chalk, diphenylolpropane, carbon black and additionally contains metal-containing lubricant with acidic number at most 30 mg KOH/g. Lubricant is obtained by interaction of alpha-branched saturated monocarboxylic C10-C28-acids with polyhydric alcohol at 180-220°C in molar ratio of 1:(1-2) in presence of bivalent metal oxides: CaO, PbO, ZnO, MgO, BaO or two-component mixture thereof in ratio of 0.25-1:0.5-1, in amount of 0.5-2.0 mass % calculated as total reaction mass. As polyhydric alcohol ethylene glycol, glycerol, polyglycerol, which represents slop from glycerol distillation, are used.

EFFECT: articles with increased extension strength, elongation, heat resistance, improved appearance, decreased brittle point; resin composition assortment expansion.
