Рослинні воски як модифікатори властивостей еластомерних і полімерних композицій

Abstract

We investigated the possibility of a complex use of vegetable waxes as modifiers of surface properties of polymeric composites. The wax samples were extracted from vegetable raw materials and then introduced into the rubber formulations used for the manufacture of the sidewalls of passenger tires and pigmented paints as a dispersant additive. Physical-mechanical properties of the obtained compositions were determined. The introduction of the investigated wax into serial rubber formulations does not impair the technical characteristics of the mixtures. The investigated waxes ensure a good protection of the elastomeric compositions against atmospheric aging. The waxy substances can be effectively used as additives that increase the ability of inorganic pigments to dispersion. The results showed that the introduction of the wax increased the hardness of the film coatings of paint-and lacquer materials, the gloss of the prepared coatings being not substantially decreased.
