Abstract

The research aimed to study the ageing resistance of vulcanized dock vendor with rice husk ash filler and coupling agent.  The experimental research used non Factorial Completely Randomized Design and each treatments was replicated three times.  Single factor concentration of ratio of rice husk ash and coupling agent 3-methacryloxypropyl trimethoxysilane (MPS) (70 phr: 1 phr, 100 phr: 1 phr, 130 phr: 1 phr, 160 phr: 1 phr, 190 phr: 1 phr and 220 phr : 1 phr). The parameters were hardness, tensile strength, elongation at break and ageing resitance before and after ageing. The results showed that all treatments have a influence on vulcanized dock fendor and meet the quality requirements SNI 06-3568-2006 for treatment concentration of ASP70 tol ASP160 with characteristics hardness  of 70 Shore A, 75 Shore A, 78 Shore A dan 80 Shore A after ageing 68 Shore A, 72 Shore A, 76 Shore A dan 78 Shore A. The tensile strength before (19 N / mm2, 21 N / mm2, 17 N / mm2 and 16 N / mm2), after ageing (17 N / mm2, 20 N / mm2, 15 N / mm2 and 15 N / mm2). ASP70 to ASP220 treatment concentration up to the elongation at break before (350%, 345%, 330%, 220%, 209% and 200%), after ageing (343%, 335%, 325%, 216% and 200%). Tear resistance characteristics before (15.6 kg / cm, 17.2 kg / cm, 17.9 kg / cm, 18.2 kg / cm, 19 kg / cm and 20 kg / cm), after ageing (15 kg / cm, 16.1 kg / cm, 17.5 kg / cm, 17.9 kg / cm, 18.7 kg / cm.

Abstract

Natural starch can be made into modified starch with the desired properties or as needed. Composite of starch and natural rubber for the made of rubber sheets as an alternative to reduce the use of natural rubber in large quantities. The research aimed to study the characteristics of sheets rubber with composite modified starch - latex. The experimental research used non Factorial Completely Randomized Design and each treatments was replicated three times. Single factor of starch and latex modification ratio (Treatment A Starch modification: latex = 1: 1 (500 ml: 500 ml, Treatment B Starch modification:latex = 1:2 (500 ml: 1000 ml and Treatment C Starch modification:latex = 2:1 (1000 ml: 500 ml)). The parameters were plasticity (Po), plasticity resistance index (PRI), mooney viscosity and dirt content. Results showed that the comparison treatment of starch and latex modifications have a influence on the characteristics of sheet rubber meet the quality requirements of Standard Indonesian Rubber (SIR) 20 SNI 06-1903-2000 and standard quality commercial sheets rubber with charactheristics plasticity (Po), plasticity resistance index (PRI), mooney viscosity and dirt content.
