Abstract

Folipaduan polikloroprena-resin fenolik merupakan gabungan dari karet polikloroprena dengan perekat resin. Polikloroprena mempunyai sifat lentur tetapi kurang kuat dari segi mekaniknya sedangkan resin fenolik mempunyai sifat kuat dari segi mekaniknya tetapi tidak elastis sehingga diharapkan dengan adanya blending kedua senyawa ini, akan dihasilkan produk yang kuat dan lentur yang dapat diaplikasikan dalam pembuatan adhesif (perekat). Pada penelitian ini dilakukan uji viskositas dan sifat mekanik terhadap kazet polikloroprena jenis A dan M yang sudah divariasi komposisinya dan sudah dipadu dengan resin fenolik dengan komposisi karet 60, 70 dan 80 %. Polipaduan polikloroprena-resin fenolik yang mempunyai sifat mekanik terbaik yaitu pada perbandingan komposisi karet jenis A:M sebesar 100:0 dengan kadar karet polikloroprena 70% dan kadar resin 30% yaitu 1015 KN/m2 dimana nilai viskositasnya 8400 cps dikarakterisasi struktur kimianya dengan spectrometer transformasi infra merah (FTIR). Hasilnya konsentrasi gugus-gagus fungsinya lebih besar dari pada sample yang lain. Sampel adesif yang memiliki sifat mekanik terbaik ini lalu dikondisikan dalam garam dan didapatkan kenaikan sifat mekanik sebesar 32,90%. Hasil sampel pada pengkondisian garam ini juga dikarakterisasi strukturnya dengan FTIR. Hasilnya secara umum banyak sekali gugus gugus yang hilang.

Polychloroprene-phenolic resin polyblend is made by combining polychloroprene rubber with resin adhesive. Polychloroprene has elastic characteristics but is mechanically less strong, whereas phenolic resin has high mechanical strength but is not elastic. Therefore, by blending these two compounds, a product with both strength and elasticity is expected to be obtained, which can be applied in adhesive manufacturing. In this research, viscosity and mechanical properties were analyzed for type A and M polychloroprene rubber with varying compositions blended with phenolic resin at rubber contents of 60%, 70%, and 80%. The polychloroprene-phenolic resin polyblend with the best mechanical properties was obtained at an A:M rubber composition ratio of 100:0, with a polychloroprene rubber content of 70% and a resin content of 30%. The mechanical strength reached 1015 kN/m², with a viscosity of 8400 cps. The chemical structure of the sample was characterized using Fourier-transform infrared spectroscopy (FTIR). The results showed that the concentrations of functional groups were higher than those in the other samples. The adhesive sample with the best mechanical properties was then conditioned in a salt solution, resulting in a 32.90% increase in mechanical properties. The sample after salt conditioning was also characterized using FTIR. The results showed that many functional groups had disappeared.
