Abstract
U ovom radu istraživan je utjecaj dodatka magnezijeva hidroksida na toplinska svojstva poli(vinil-klorida). Procesom ekstrudiranja dobivene su mješavine PVC/MH u različitim omjerima. Toplinska razgradnja mješavina PVC/MH provodi se kroz dva razgradna stupnja što se vidi iz odgovarajućih TG i DTG krivulja kroz pojavu dvaju pikova, odnosno minimuma. Iz podataka dobivenih termogravimetrijskom analizom može se zaključiti da se dodatkom magnezijevog hidroksida povećava toplinska stabilnost polimernih mješavina. Kinetička analiza procesa TG razgradnje mješavina PVC/MH temelji se na eksperimentalnim podatcima za svaku pojedinu brzinu zagrijavanja i iz njih izračunatim temperaturama pri kojima su postignute odabrane konverzije. Primjenom dvije izokonverzijske metode: Friedmanove i Flynn-Wall-Ozawove, utvrđeno je da se vrijednosti energije aktivacije mijenjaju ovisno o sastavu istraživane mješavine, a u pravilu se povećavaju povećanjem udjela MH-a.
Abstract (english)
In this paper the effect of magnesium hydroxide addition on the thermal properties of polyvinyl chloride was investigated. Extrusion processes produced PVC/MH mixtures at different ratios. Thermal decomposition of PVC/MH mixtures is carried out through two degradation steps as can be seen from the corresponding TG and DTG curve through the appearance of two minimums. From the data obtained by thermogravimetric analysis it can be concluded that the addition of magnesium hydroxide increases the thermal stability of the polymer blends. The kinetic analysis of the TG degradation process of the PVC/MH blend is based on experimental data for each individual heating rate and the calculated temperatures at which the selected conversion is achieved. Using two isochronous methods: Friedman and Flynn-Wall-Ozawove, the activation values are varied depending on the composition of the investigated mixture and are generally increased by increasing the share of MH.
