IMPACT OF SOLID SPHERICAL FILLERS ON PHYSICAL AND MECHANICAL PROPERTIES OF COMPOSITE COATINGS BASED ON PHENILONE
Urgency of the research. Polymer materials have been used in many industries for a long time; they are often used as an alternative to metal parts. At the same time, polymeric materials can exceed traditional materials in some characteristics, but inferior in others. Recently, polymeric materials with increased adhesion properties have been developed, so the actual task is to study their physical and mechanical characteristics for estimation of their usage in industry perspectives. Target setting. Target is the physical and mechanical characteristics of the polymer materials with high adhesive properties. Actual scientific researches and issues analysis. There are many researches of physical and mechanical characteristics of different types of polymers; also, there are polymers with high adhesive characteristics developed. Uninvestigated parts of general matters defining. There are many researches of physical and mechanical characteristics of polymers, but there are not enough information about materials with increased adhesion characteristics based on phenilone. The research objective. The objective is an experimental study of the physical and mechanical properties of composite coatings based on phenilone, in particular various types of strength, elasticity, microstructure, etc. The statement of basic materials. In the beginning of the article, the general analysis of phenilone-based polymers is performed and necessity of its physical and mechanical characteristics study is shown. Then results of various types of strength, elasticity, microstructure, etc. characteristics experimental studies are presented. Conclusions. It is found, that insertion the most part of proposed fillers causes to increase of such parameters as microhardness, wear resistance, modulus of elasticity and some reduction of strong characteristics. An appearance of particle conglomerates on coating surface at filler part >20% is shown, that causes decrease of operational properties of the coatings.
