| dc.description.abstract | This research examined the effect of benzoyl peroxide as a cross-linking
initiator on the adhesive characteristics of natural rubber (SIR-10)/epoxidized
natural rubber (KAE) with microbentonite filler. Benzoyl peroxide is used to crosslink
natural rubber adhesives and epoxidized natural rubber with the addition of
benzoyl peroxide variations from 0.5; 1; 1.5; 2; and 2.5 (phr). Xylena,
ZnO,Microbentonite, BHT, C9 resin, and PET film are used as solvents, activators,
fillers, antioxidants, tackifiers, and substarts in rubber mixtures. The mixture of
natural rubber (SIR-10) and epoxidized natural rubber (KAE) was then mixed until
homogeneous and left to stand. Next, the mixture is poured onto the PET film
substrate and then dried at room temperature. Then the mixture was heated using an
oven at 80℃ for 30 minutes. Next, the mixture was characterized using a peel test.
The peel test results showed that the optimum mixture occurred at a variation of 2.5
phr benzoyl peroxide, namely 47,264 N/m. The optimum results from the peel test
will then be carried out for characterization tests using the SEM test, XRD test and
wettability test. Morphological analysis using SEM shows that the optimum
composition on the surface displays better adhesion by forming a homogeneous
phase. XRD analysis shows that cross-linking has occurred with a degree of
crystallinity of 96% and has stable peaks of 31.822°, 32.741° and 36.294°.
Wettability analysis shows that the optimum composition is at a water contact angle
of 73° which produces neutrally wet properties which display high wettability where
the liquid wets the surface well. | en_US |
