Abstract

AbstrakTelah dilakukan pembuatan dan karakterisasi mekanik papan partikel berbasis cangkang buah karet dengan perekat limbah plastik polipropilen.  Papan partikel dibuat dengan variasi berat serbuk cangkang buah karet masing-masing 50 gram, 100 gram dan 150 gram, dicetak dengan ukuran 28 cm ´ 12 cm ´ 4 cm. Campuran serbuk cangkang dan perekat selanjutnya dikempa menggunakan alat press sederhana selama 1 jam dalam keadaan panas, kemudian didiamkan selama 7 hari pada suhu kamar. Karakterisasi papan partikel meliputi pengujian sifat fisika dan sifat mekanik. Papan partikel yang terbuat dari limbah plastik polipropilena dan cangkang buah karet memiliki kerapatan 0,81 – 0,88 g/cm3, kadar air 0,34 – 0,93%, daya serap air 5,67 – 10,69% dan tebal pengembangan 0,26 – 1,62%. Hasil uji sifat mekanik papan partikel dari serbuk cangkang buah karet dan plastik polipropilena menunjukkan nilai keteguhan patah 53 – 56,54 kgf/cm2, nilai keteguhan elastis 253,85 – 400,87 kgf/cm2 dan kuat cabut sekrup sebesar 1,96 kgf/cm2. Kata kunci: Cangkang buah karet, polipropilena, papan partikel, sifat fisika dan mekanik  AbstractPreparation and characterization mechanical properties of particles board based shells fruit rubber use plastic of polypropylene waste as adhesive has been done. Preparation of the Particle board based shells fruit rubber and plastic of polypropylene addition with variation of 50, 100 and 150 grams. The Particle board was printed on the same size 28 cm ´ 12 cm ´ 4 cm. Blending of the internal shell powder and adhesive of polypropylene used a hot press for 1 hour, then settled for 7 days at room temperature. Characterization the particles board includes of the physics and mechanical properties. It is the density 0.81 – 0.88 g/cm3, of the water content 0.34 – 0.93%, water absorption 5.67 – 10.69% and the thickness board expansion 0.26 – 1.62%. The values of MOR and MOE of particle board was 53.00 – 56.54 kgf/cm2, and 253.85 – 400.87 kgf/cm2. The values of strong pull secrew was 1.96 kgf/cm2. Keywords: Shells fruit rubber, polypropylene, particle board, physic and mechanical properties

Abstract

This research aims to develop adhesives from liquid rubber compounds with a variety of tackifiers, a combination of copal resin, and turpentine oil. It also aims to characterize the adhesives to determine the quality of the adhesives produced. The research comprised several stages, including the preparation of rubber additive dispersions and solutions, formulation of liquid rubber compounds and adhesives, fabrication of test pieces, and subsequent characterization. The liquid rubber compound is made by mixing concentrated latex with rubber additives, which include KOH as a stabilizer, stearic acid and ZnO as an activator, BHT as an antioxidant, CaCO3 as a filler, MBTS and TMTD as an accelerator, and sulfur as a vulcanizer. The adhesives are made by mixing liquid rubber compound with tackifier material with various combinations of copal resin/turpentine oil, namely F1 (0 gram/4 gram); F2 (1 gram/3 grams); F3 (2 grams/2 grams), F4 (3 grams/1 gram), and F5 (4 grams/0 grams). Adhesives characterization was carried out by testing pH, viscosity, adhesives strength, FTIR, XRD, and thermal analysis. The research results showed that the best conditions were obtained on F4 adhesives with an adhesives strength value of 1.7452 N/mm, viscosity of 1100 cP, and pH 4.6. In this condition, the resulting adhesives meet the requirements for adhesives in accordance with SNI 06-6049-1999 and SNI 12-7195-2006.
