Abstract

Rekayasa terhadap epoksi terus dilakukan sebagai upaya untuk meningkatkan sifat mekanik, ketahanan termal, fisika dan kimia. Rekayasa yang dilakukan berupa penambahan material lain sebagai curing agent maupun material kedua untuk meningkatkan sifat dari termoset epoksi. Penggunaan senyawa lain sebagai curing agent telah lama dikomersialkan, namun kendala yang ditimbulkan adalah pengaplikasian termoset epoksi pada bidang tertentu terutama pada bidang yang membutuhkan kekuatan impak dan stabilitas termal masih rendah. Oleh sebab itu, dibuat senyawa curing agent yang mampu meningkatkan sifat mekanik atau stabilitas termal. Preparasi bahan penelitian diperoleh melalui sintesis curing agent menggunakan phthalic anhydride-containing polyaminoamide dan penyediaan material kedua berupa RTV silicone rubber secara komerisal. Tujuan penelitian untuk menganalisis pengaruh penambahan RTV silicone rubber dan phthalic anhydride dengan komposisi (0, 5, 10, 15, 20) wt% terhadap sifat mekanik, stabilitas termal, sifat fisika dan kimia termoset epoksi. Pengujian dan karakterisasi dilakukan terhadap termoset epoksi/PAA/RTV silicone rubber maupun terhadap termoset epoksi/PAA/phthalic anhydride. Untuk penambahan RTV silicone rubber: kekuatan tarik, elongation at break dan kekerasan mengalami penurunan, kekuatan impak mengalami peningkatan maksimum pada penambahan 15% RTV silicone rubber sebesar 6175 J/m2. Temperatur degradasi mengalami peningkatan maksimum pada penambahan 15% RTV silicone rubber yaitu 328 dan 349oC masing-masing pada 5 dan 10% degradasi. Swell ratio mengalami peningkatan, chemical resistance dan penyerapan air mengalami penurunan. Pada penambahan Phthalic anhydride: kekuatan tarik dan kekerasan mengalami penurunan. Elongation at break meningkat pada 15% PA sebesar 21,55%. Kekuatan impak meningkat pada 20% PA sebesar 5451 J/m2. Temperatur degradasi mengalami penurunan. Swell ratio mengalami peningkatan, chemical resistance dan penyerapan air mengalami penurunan. ==================================================== Since the pristine epoxy has several weaknesses, it usually modified by adding the other materials either as a curing agent as well as a second material that is able to improve the properties of thermoset epoxy ie, mechanical properties, thermal stability, physical and chemical properties. Using of other compounds as curing agents has long been commercialized, but the constraints posed is application of an epoxy thermoset in specific fields, especially in fields that require impact strength and thermal stability are still low. Therefore, compound curing agent which can improve mechanical properties or thermal stability are made. Preparation of research material obtained by the synthesis of curing agent using phthalic anhydridecontaining polyaminoamide and provide a second material commerical as RTV silicone rubber. The purpose of this study was to analyze effect addition of RTV silicone rubber and phthalic anhydride with composition (0, 5, 10, 15, 20) wt% on the mechanical properties, thermal stability, chemical and physical properties of thermoset epoxy. Testing and characterization are applied to both thermoset epoxy/PAA/RTV silicone rubber and thermoset epoxy/PAA/phthalic anhydride. In addition RTV silicone rubber: tensile strength, elongation at break and hardness decreased, impact strength increase at maximum 15% on addition of RTV silicone rubber is 6175 J / m2. The maximum degradation temperature increase in addition of 15% RTV silicone rubber. It are 328 and 349oC respectively at 5 and 10% degradation. Swell ratio increase while chemical resistance and water absorption decrease. In addition phthalic anhydride: tensile strength and hardness is decrease. Elongation at break increase at 15% PA amounted to 21.55%. Impact strength increase at 20% PA amounting 5451 J/m2. Degradation temperature has decrease after addition of phthalic anhydride. Swell ratio is increase, chemical resistance and water absorption decrease.
