Abstract

Background. It is proposed to use coloured modified dispersions of montmo­rillonite to ensure high physical and mechanical properties of polymer films and to give intense colour to the leather finish coating. The introduction of modified mineral dis­persions into the polymer matrix allows the polymer to be structured and provides impro­ved physical and mechanical properties of the leather coating.
The aim of article is to study the influence of coloured modified dispersions of montmorillonite on the physical and mechanical properties of polymer films in order to form polymer-mineral coating with a high level of resistance before usage.
Materials and methods. Acrylic polymer and coloured modified montmorillonite dispersions were used for the study. The physical and mechanical properties of the obtained polymer-mineral films were evaluated by the indices of the conditional modulus of elasticity, tensile strength, relative elongation at break points, swelling and content of water-bearing substances.
Results. The introduction of coloured modified dispersions of montmorillonite to the polymer corrects the quality of the leather finish coating. The study of the effect of coloured modified dispersions of montmorillonite on the physical and mechanical properties of polymer acrylic matrices indicates the structural and elastic changes of the polymer film indices at different loads and elongations. The effect of structuring of poly­mer films and changes in physical and mechanical properties are amplified at higher temperatures of the coating formation.
Conclusion.  It was found that the introduction of coloured modified dispersions of montmorillonite into the acrylic film-forming agent contributes to the enhancement of the physical and mechanical properties of polymer films. The maximum level of film strength is achieved when 1.52.0 % of montmorillonite is lost from weight of polymer. It is shown that the structuring of the polymer is enhanced by the formation of the polymer-mineral coating at a temperature of 60 °C. The formation of physical and mechanical properties of polymer-mineral films for leather coating is caused by chemical interactions between the active centres of the mineral and the functional groups of azo dyes and polymer.
