Abstract:Živimo v obdobju, v katerem si skoraj ne moremo predstavljati življenja brez plastike - termoplastov. Poznamo več različnih vrst plastike, ki ima vsaka svoj namen, različni aditivi pa omogočajo njen obstoj in funkcionalnost. V diplomskem delu smo se osredotočili na vpliv aditivov na lastnosti polimernih barvnih koncentratov, ki jim z eno besedo rečemo masterbatch-i. Masterbatch je barvni koncentrat oziroma koncentrat aditivov, namenjen obarvanju termoplastov ter za izboljšanje njihovih lastnosti. Je v obliki granul koncentrirana mešanica pigmentov in dodatkov, ki se skozi toplotni proces z ustreznim polimernim nosilcem strne v tekočo maso in se po hlajenju peletizira v obliko granul. Granule so primerne za barvanje plastičnih mas in obstajajo v široki paleti odtenkov z različnimi deleži pigmenta in koncentracijami različnih dodatkov, s katerimi se izboljša kakovost oziroma se zagotovi določena lastnost polimernih izdelkov. Industrijsko delo je vključevalo proizvajanje polimernih barvnih koncentratov – masterbatch-ev. Z dodajanjem različnih koncentracij aditivov smo vplivali na lastnosti končnega produkta, kjer nas je zanimala barvna moč oz. izdatnost barve (nianse) masterbatch-a in vzorce med sabo primerjali. Barvno moč smo vzorcem merili z spektrofotometrom in za vsakega naredili izračun polne lastne cene (PLC). Eksperimentalno delo in analizo vzorcev smo opravili v razvojnem laboratoriju za masterbatch-e v Cinkarni Celje, PE Kemija Mozirje, in je potekalo pod enakimi pogoji za vse merjene vzorce. Testirali smo masterbatch-e s pigmenti in različnimi aditivi, ki bi bili konkurenčni MB na trgu, vendar z dobljenimi rezultati nismo dosegli zastavljenega cilja, kar pripisujemo morebitnim nastavljenim procesnim parametrom ali previsokemu doziranju pigmenta (40 %).

Title:EFFECTS OF ADDITIVES ON THE PROPERTIES OF POLYMERIC COLOR CONCENTRATES
Abstract:These days we find it almost impossible to imagine our lives without the use of plastics – thermoplastics. There are several kinds of plastics. Each of them serves a certain purpose; various additives enable their existence and functionality. In this thesis we have focused on additives impact on polymer color concentrates characteristics, known also as masterbatchs. Masterbatch is a colour concentrate or additive concentrate used for coloring thermoplastics as well as for improving their characteristics. It is a concentrated blend of pigments and additives in the form of granules, which through heat process with corresponding polymer carrier condenses into a liquid mass and is pelletized into granules after cooling. Granules are suitable for colouring plastic masses. There are wide ranges of shades with various shares of pigment and concentrations of different additives used for quality improvement or ensuring certain characteristics of polymer products. Industrial work included the production of polymer colour concentrates – masterbatchs. By adding different additives concentrations we influenced the characteristics of end product, where we were interested in color strength or abundance of masterbatch color and we compared the samples. The strength of colour of the samples was measured by spectrophotometer and a calculation of full cost pricing (FCP) was made for each of them. Experimental work and samples analysis were carried out at development laboratory for masterbatchs at Cinkarna Celje, BU Kemija Mozirje. It was carried out under the same conditions for all measured samples. We tested masterbatchs with pigments and different additives, which could be competitive MB on the market. However the acquired results did not meet the set goal. We attribute this fact to possible process parameters setting or pigment overdose (40%).
