Abstract
U ovome radu istraživan je utjecaj polimernog dodataka, poli(metil-metakrilat-ko-dodecil-metakrilat-ko-oktadecil-metakrilat) na viskoznost mineralnih baznih ulja SN 150 i YUBASE 4 pri 0 ± 1 °C i 40 °C. PAMA su najčešće terpolimeri smjese alkilnih metakrilata sastavljeni od monomera s promjenjivim udjelom bočnih alkilnih skupina, pretežito s C1, C12, C18 ugljikovih atoma. Metodom kapilarne viskozimetrije dobivene su vrijednosti relativnih i reduciranih viskoznosti polimernih otopina raznih koncentracija te su na temelju toga određeni parametri Hugginsove jednadžbe, a to su Hugginsova konstanta, intrizična viskoznost i nagib Hugginsova pravca. Oni nam ukazuju na molekulska međudjelovanja u otopinama polimera u baznim uljima, što je neophodno za optimalnu primjenu u mazivim uljima i formuliranje sa drugim aditivima.
Abstract (english)
In this paper, the effect of a polymeric additive, poly(methyl-methacrylate-co-dodecyl methacrylate-co-octadecyl-methacrylate) on the viscosity of mineral base oils SN 150 and YUBASE 4 at 0 ± 1 °C and 40 °C was investigated. PAMA are most often terpolymers of a mixture of alkyl methacrylates composed of monomers with a variable proportion of side alkyl groups, predominantly C1, C12, C18 carbon atoms. Capillary viscosimetry method was used to obtain relative and reduced viscosity of polymer solutions, and based on that viscosimetric parameters of the Huggins equation were estimated, namely Huggins constant, intrinsic viscosity and slope of Huggins line. They indicate the molecular interaction in polymer solutions in base oils, which enables us to optimally apply them in lubricating oils and to combine them with other additives.
