Microfilled Epoxy-Composites, Capable of Thermo- Hardening and Thermo-Plasticization After Hard Heating (200-300ОC) - For “in-Field\Offroad” Use in Bio-, Agro-, Medservice
Journal Title: Biomedical Journal of Scientific & Technical Research (BJSTR) - Year 2019, Vol 19, Issue 1
Abstract
The work is devoted to the study of a new type of composites for the manufacture of special details, parts, tools or adhesive repair in the field. We have developed epoxy compounds that preserve or increase strength and ductility after heating at 200-250oC. That let, if necessary, an effective thermo-disinfection of composite toolsproducts at elevated temperatures. It is believed that conventional epoxy resins are unable to retain their physical and mechanical properties after heating above 200°C. Their feature is in simplicity of making (ordinary filling with available\cheap microfillers) without special qualification of personnel and in any conditions (outside clinics, laboratories and service centers). In this work some of such compositions (with SiC, TiN, SiO2-marshalite, cement) are considered. It offers to name such composites of “thermo-harden” or “thermo-plasticized”. Bioneutrality, durability and heat-resistance, at 200-300оС does him a good material for rapid repair and making of the special or failing instruments in the field, travelling, military and other difficult terms.Requirement in effective repair and 3D-copyright compositions for ambulances and research groups “in-field” is actual now. Even appearance of 3d-printers and single-use cheap instruments decides a problem only on the insignificant moving away from cities or service centers. In regions with the low level of hygiene, the deficit of instruments (special, new or quality) appears industry or populated constantly. And such regions even now is majority - and it is Sahara\Africa, Antarctic Continent or Siberia not only. Low-habitate and deprived many blessing of civilization even such regions as west of China, west of the USA, north-west of the USA and Canada, mountain districts of Asia and South America. Problems with the quality providing are present and in Europe and inhabited regions, in periods of geo-, techno-, military and social troubles. Epoxy resin is open 120 years ago by Russian chemists Dianine (his name in term “EpoxyDian resin”) and Prilezhaeff [1]. Until now, possibility of epoxy resin as rapid repair-copying material still not used full. Her dignities also not always are estimated. We will lead a few from them:
