METHOD FOR PREPARING COMPOSITION COVER FOR RECOVERY METALLIC SURFACE Russian patent published in 2005 - IPC

FIELD: composition materials.

SUBSTANCE: invention relates to a method for preparing the composition cover that can be used for recovery worn out article surfaces working under conditions of high compression loadings, bearing surface of lateral framework in loading truck car in zone of slipping aperture. Method involves mixing the polymerizing epoxy composition and metallic dispersed filling agent in the ratio = (1:6)-(1:9) mas. p. p. Mixing is carried out at effect in increasing pressure in auger mixer with alternate step being each the following auger step differs from previous step by the constant value. Then the prepared composition is applied on metallic surface and kept its at the polymerization temperature up to finishing the solidification process. Composition based on epoxy resin ED-16, ED-20 with latent hardening agent dicyandiamide is used as epoxy composition. Iron powder PZH-4, iron-base powder PS 27-M, iron-base PG-USCH-35, nickel-base powder PG-SP2-M are used as a metallic dispersed filling agent. Invention provides enhancing the specific compression loading value.

EFFECT: improved method for preparing, valuable properties of cover.
