Abstract

In the construction was widespread elastomer profiles, which have the ability to swell in water. Such products should have a high capacity for swelling, elasticity, resistance to weathering. At the present time for these purposes are used materials, mostly of foreign origin. With the increasing pace of construction in Russia the problem of replacement of imported materials is particularly relevant. The work was dedicated to the creation of water-swellable elastomer materials using bentonite powders and study of their properties. Сomparative testing of imported and domestic hydrophilic sealants were held. Rationale and choice of components for the cords of bentonite was conducted. Polymer base is saturated ethylene-propylene rubber. Bentonite from different manufacturers used to increase the swelling of the samples. Filler added in an amount of 50–100 phr. The elastomeric compositions were prepared using laboratory roller at a temperature of 60 ± 5° C. Profiling was performed on a syringe-machine at a temperature of 120° C. Extrusion indicator of the mixtures were evaluated on a 10-point scale (German-Russian system). It is found that high swelling products provided using field Azerbaijan bentonite. It is noted that the dosage of bentonite than 150 w.p. deteriorates technological properties of bentonite cords. It has been shown that activation of the bentonite and sodium carbonate chloride can significantly improve product swelling, wherein the bentonite content of the composition was 150–200 w.p.
