Composite elastomeric materials filled with modified mineral fillers

Abstract

In the paper, the influence of modified Angren kaolin on the properties of composite elastomeric materials based on butadiene-styrene rubber has been established that the addition of modified Angren kaolin into rubber mixtures instead of gas pedals, activators and mineral fillers causes intensive connection of sulfur with macromolecules. Adsorbed sulfur on the surface of particles of modified Angren kaolin and its uniform distribution in the composition and formation of the structure with equal force were determined. This effect shows that the modified Angren kaolin in the curing processes accelerates and activates and affects the formation of the curing grid with equal strength and helps distribution throughout the composite. It has been established that introduction of MAK into the composition of elastomers more than 50 wt. % per 100 wt. % of rubber changes technological and technical properties of composite elastomeric materials. The application of modified Angren kaolin instead of the gas pedal, activator of vulcanization and mineral filler in composite elastomeric materials allows making rubber goods of various purposes.

Creation of elastomer-based compositions with special characteristics for the wheel-engine block of thermal locomotives

“…The objects of study are furan oligomers and secondary raw materials for the production of acetylene; as a standard rubber mixture, we used nitrile butadiene rubber [6,7]. The production of rubber mixtures was carried out on laboratory mixing rollers RC-WW 150/330 (Rubicon, Germany).…”

Waste material fly ash as an alternative filler for elastomers

“…Because OPA contains silica, it represents the ability to be used as a filler. 26 The result of this use showed that it improved the physical, mechanical, thermal, water barrier, and biodegradable properties of polymers. 27 In addition, by-products from agriculture as rice husk ash (RHA) for instance consist of 15-17 wt.% silica, 28 and can be added to the polymer matrix.…”

Investigation of some physico-chemical properties of Elaeagnus L. Gum

“…It is possible to use gum Elaeagnus L. to obtain a ceramic mass with a uniform distribution of components with an optimal consistency in producing composite materials with micro-and nanometals and in the transformation of graphite [9,10]. In addition, using this gum, it is possible to obtain different compositions with various dispersed nanofillers, such as modified kaolin and carbon, which can be used to produce paint and varnish or rubber materials [11,12]. We have studied the methods of extraction of polysaccharide from this gum Elaeagnus L. purification, determination of monomeric composition, molecular weight, change in solution viscosity under different conditions, UV and IR spectra of polysaccharide.…”
