alkyl-phenol-formaldehyde resin and dibutyltin dilaurate with finely dispersed iron-oxide filler depending on their production method (solution method or melting method) using the high-resolution optical microscopy technique was carried out. When obtaining polymer composites (films)
the authors varied the ratio between the main components of the polymer matrix urethane isocyanate and phenol-formaldehyde resin (1:2 or 1:3) and the content of the finely dispersed iron-oxide filler in relation to the polymer binding medium (0.1 0.6 and 1.2 wt%). In the modes of bright field phase contrast and crossed nicols the homogeneity of the obtained films their structure aggregation capacity and distribution uniformity of the powdered iron-oxide filler as a part of the polymer matrix were investigated.

| Popis: | A study of the morphology and structure of waterproof film coatings based on polyurethane isocyanate, alkyl-phenol-formaldehyde resin and dibutyltin dilaurate with finely dispersed iron-oxide filler depending on their production method (solution method or melting method) using the high-resolution optical microscopy technique was carried out. When obtaining polymer composites (films), the authors varied the ratio between the main components of the polymer matrix, urethane isocyanate and phenol-formaldehyde resin (1:2 or 1:3), and the content of the finely dispersed iron-oxide filler in relation to the polymer binding medium (0.1, 0.6 and 1.2 wt%). In the modes of bright field, phase contrast and crossed nicols, the homogeneity of the obtained films, their structure, aggregation capacity and distribution uniformity of the powdered iron-oxide filler as a part of the polymer matrix, were investigated. The obtained composite material in the form of film coating or adhesive repair compound can be used for waterproofing, repairs and corrosion protection as film coatings of water and underwater hydraulic structures. |
