Краткий осмотр (реферат): The influence of regularities of the chemical-mineralogical nature, the dispersity,and the surface properties of inorganic fillers on the pro-tective properties of epoxy polymer composite materials have been investigated. Polymeric compositions based on epoxy resin of ED-20 brand and aliphatic amine curing agent of diethylenetriamine of DETA brand have been chosenas the research materials. The fillers were the air-dry dispersed materials of different nature: oxide, clay and quartz. The resistance of the composites to water and aqueous solutions (absorbency) was investigated by dipping the samples into an aggressive aqueous medium.For the received samples of the filled compo-sites, thermogravimetric (TG) and differential scanning calorimetry (DSC) method were used using the SDT Q600 device manufactured by TA Instruments (USA). It has been found that the thermal stability and the absorbing capacity of the filled composites in water and aque-ous acidic and alkaline mediums correlate with each other. It has been shown that to obtain materials with improved protective characteris-tics, it is necessary to use oxide or clay fillers with the basic (alkaline) surface function.
Описание: Composite materialsbased on epoxy resins arecommonly usedas gluing agents for element connection with various surfaces (con-crete, stone, wood, metal, glass), protective coatings that increase the service life of traditional materials, constructive elements for building structures and infrastructure object reconstruction and renovation as well as independent building elements and architec-tural construction creation (poured floor, fiber-glass products, etc.) [1-5].High strength, resistance to aggressive media and non-toxicity make it possible to use epoxy materials to restore water pipelines [6] and drainage [7]. Sufficient endurance under the in-fluence of γ-radiation causes the use of epoxy polymer coatings for infrastructure objects in nuclear power [8]. The technologies are developed and the efficiency of restoration of bearing portable wooden beams and elements with the use of polymeric composi-tions based on epoxy resins is shown [9-11].The urgent direction is the use of epoxy polymers in preservation and restoration of architectural monuments, as well as for the de-sign of products [12, 13]. Epoxy-silicate hybrid materials were found to be most effective for the restoration of stone, glass and ceramic elements of architectural heritage [12-16]
