In a function of filler was used natural zeolite which is from a group of hydrated aluminosilicates. The prepared modified. polymer compounds were · characterized by physical-mechanical properties ·of vulcanizates. The found values were compared with the values of commercially used polymer materials with the. original filler carbon black [ 1,2]. Key words: natural zeolites, filler, physical-mechanical properties 1. IntroductionThe basic polymer compound includes natural rubber, vulcanization system and plasticator.One of important additives of rubber compound are filler too. lnorganic materials are adding in polymer materials in fonn of filler. The application of inorganic materials in organic polymers is one of usual way to inprove up of mechanical properties for example hardness, tensile straight, module of polymer materials [ l ]. Present paper studies possibility of applications of natural zeolite in preparation of modified rubber compounds and evaulate the influence of addition light filler on properties of resultant vulcanizer. Following measure give the infonnation about rheology, vulcanization performance and pbysical-mechanical properties modified rubber compound on the base of natural zeolites. 2. ExperimentalThe sample of natural zeolite was used in a function of filler in rubber compound. Tbe modelcompound was select on the base of natural rubber (SMR-20) [2]. As a reference filler was used a carbon black (N660), because a size of their particles was approximately equal as a si7.e of particlesofused natural zeolite. The model rubber compounds were prepared by two-step mixing on laboratory mixer Plastograf-Brabender by standard procedure. Tbe fust step was made at the temperature 140 °C aad aIlle of rotation pinions was 50 rpm/min. [3]. At the preparation of modified rubber compounds were Uled an activator of vulcanization (ZnO) and an accelerator of vulcanization N-cyclohexyl-2-benzothiazolsulfenamid (CBS) besides the natural rubber. ln the second step, which was made at the temperature 11 O °C and at same rate was added a polymer sulphur in function of vulcanization agent(SuJphur N). A composition of prepared modified rubber compounds is given in Tahle I. Sample 2 -modified rubber compound with the substitution of all amount of filler clinoptilolite. Sample 3 -modified rubber compound with the substitution of 1/2 amount of filler clinopblolite. 7
