Based on a combination of a system-oriented approach and a synergetic concept, the requirements for the design of tribological polymer composite materials with high-modulus fillers are formed. These materials are considered as an open dynamic system that evolves during operation. The principles of the synergetic concept for tribotechnical systems taking into account the theory of evolution and self-organization to ensure its self-governing and self-supporting development are considered. It is revealed that in the process of interaction of elements of the tribosystem the cooperation of local areas of their materials is formed with the emergence of a critical number of such areas and the creation of an information field about their functioning. The direction of self-organization of processes and states of parts materials in the tribotechnical system and expediency of using the conclusions of the synergetic concept in the construction of polymer composite materials, as well as their nonequilibrium are shown. The issues of creation of tribophysical bases of wear resistance of tribotechnical systems with conjugations of the details made or strengthened by polymeric composite materials are considered. Polymer composite materials are considered as a set of interacting ensembles of local areas, the principle of maximum wear resistance (reliability) is used. Tribological principles and requirements to creation and substantiation of expediency and efficiency of use of high-modulus fillers in polymers are formulated
A study was made of the possibility of producing composites based on natural ‘Kvaliteks’ latex that are filled (20–30 parts) with shungite (‘Karelit’). The possibility of producing such composites had been shown earlier for the natural latex ‘Revultex’ containing a vulcanising group. Therefore, all the composites investigated in the present work contained a vulcanising group (sulphur, ethyl zimate, zinc oxide), and vulcanisation was carried out at a temperature of 125°C. Into the latex was introduced an aqueous dispersion of ‘Karelit’ with dispersing agent NF. The filler content was the same as in the formulation for gloves resistant to aggressive media. The mechanical properties of films of these composites were on a par with or even slightly superior to those for the standard composites, while the acid and alkali resistances were far higher. Acid- and alkali-resistant gloves manufactured from ‘Kvaliteks’ latex filled with ‘Karelit’ shungite satisfy the specifications fully and are considerably superior to standard gloves in terms of resistance to aggressive media in long-term tests.
At present, in the polymer processing sectors of industry, natural carbon-containing mineral substances have begun to be used on an increasingly large scale as different ingredients in polymer composites, including fillers, sulphur vulcanisation activators, vulcanising agents for halide-containing rubbers and polymers containing reactive groups, components of rubber compounds based on latex composites, and so on [1, 2].
