Properties of Polymer Composite Materials Based on Linear\/Network Polyurethanes Modified with Organo-Inorganic Modifiers<\/strong><\/p>\n L.A. Markovska,<\/strong> Section: Structure and properties.<\/p>\n Language: Ukrainian.<\/p>\n Abstract:<\/strong><\/p>\n Created PKM, which are characterized by high adhesion\/cohesion characteristics (29.0-36.5)\/(40.0-43.6) MPa, and PKM with a content of MeOM:NiOM-0,32%; CuOM-0,33%; ZnOM-0,34%, which leads to an increase in adhesion\/cohesion properties, namely: (35,7\u201337,0) \/ (42,8\u201343,9) MPa and have high performance properties: indicators of water resistance of concrete samples protected by PKM, exceed this indicator of concrete initial up to 3,75 times; initial PKM and modified with MeOM are resistant to sea water and salt fog, as well as to action of special reagents at low temperatures – frost resistance of such concrete after 50 freeze-thaw cycles is 1,0\u20131,1, ie, concrete coated with PKM becomes frost resistant; concrete cubes with a protective coating have no damage, no changes in the surface of the samples and the surface of the coating, hovewer, not protected concrete cubes collapsed.<\/p>\n According to the IR data, the formation of the amide group -CONH- as a result of the addition of hydrogen of the CH group of the double bond of the MeOM molecule to the nitrogen of the NCO group of TDI was established; the change in the profile of valence and deformation bands oscillations of CH bonds of different groups indicates reactions involving CH bonds and the possibility of complex compounds formation that affect the structure of the polymer, that is to say, the active compounds are fixed in the polymer macrochain, which prevents their diffusion on the material surface and their subsequent removal and prolongs the protective functions of the coating, which has high adhesion\/cohesion strength, resistance to UV radiation, biocorrosion, and chemical agents, enhances heat resistance and provides high performance.
