FIELD: manufacturing technology.
SUBSTANCE: invention relates to production of polymer materials, such as epoxy-phenol composition, and can be used as coating for anticorrosion protection of preservation of containers. Production of epoxy-phenol composition is carried out at mixing and dispersion in bead mill for 20-40 minutes solution epoxide oligomer and butanolized solution of phenol-formaldehyde oligomer. Method controls structuration of composition and reduces power consumption owing to reduced temperature for preparing the composition from 120 °C to 20°C and time alignment solutions oligomers from 90 minutes up to 20-40 minutes, which ultimately results in considerable cost reduction of obtained product.
EFFECT: obtained epoxy-phenol compositions are characterised by high physical-mechanical operating properties.
