The purposed of this study was making an adhesive from liquid rubber compound with a variety of MBTS accelerator materials and to characterize the adhesive that has been made by testing pH, viscosity, adhesion, and functional group analysis. The basic material for making liquid rubber compound adhesives was the concentrated latex weighing 166.7 grams with dry rubber content (KKK) of 60%. Liquid rubber compound was made by mixing concentrated latex with chemical additives that have been dispersed beforehand, namely KOH as a stabilizer, stearic acid and ZnO as activator, BHT as an antioxidant, CaCO3 as a filler, MBTS and TMTD as accelerators, and sulfur as a vulcanizer. The adhesive was made by mixing liquid rubber compound with 1 gram of gondorukem. In this study, variations of the MBTS accelerator material were carried out, that are 0 grams; 1.25 grams; 2.5 grams; 3.75 grams; and 5 grams. Adhesive characterization was carried out by testing pH, viscosity, adhesive strength, and functional group analysis using an FTIR spectrophotometer. In this study, the results obtained from functional group analysis using FTIR showed the presence of -OH, -C=C, and -CH alkanes. The result of the study show that MBTS has an effect on the adhesive strength of the resulting adhesive. The best conditions were obtained when using MBTS of 2.5 grams. At this conditions the value of adhesive strength, viscosity, and pH obtained were 2.6482 N/mm; 375 cP; and 7. The results of this study have met the quality of the adhesive according to SNI 12-7195-2006. [ABSTRACT FROM AUTHOR] |
