METHOD FOR PREPARING FILLING AGENT FOR POLYMERIC COMPOSITION

摘要

FIELD: chemistry of polymers, chemical technology. ^ SUBSTANCE: invention relates to a method for preparing a filling agent used in manufacturing polymeric composition materials in making articles for structural and tribotechnical designation. Method involves mixing 0.5-10.0 mas. p. of epoxy diane resin with 100.0 mas. p. of sodium silicate aqueous solution (by dry matter) at temperature 40-60°C. Then the mixture is coagulated with mineral acid taken in the amount providing hydrogen index pH = 4.0-5.0, washed out with water and prepared solid substance as a precipitate is dried. Invention provides enhancing physicochemical and antifriction properties of the polymeric composition. ^ EFFECT: improved preparing method. ^ 5 ex
