Researches about the effects of blending method and polyisoprene concentration on the mechanical properties
of lignocellulosicfoam have been done. Preparation of
lignocellulosicfoam was Blended lignocellulosic and
polyisoprene by spraying and stirring method with various
concentration of polyisoprene 5. 10 to 45% (v/v). The study
begins by getting the lignocellulosic from coconut husk using
counter machine, a separator and sifting. Lignocellulosic as
dried sieved with 10 mesh size. Total of 30 g of lignocellulosic
mixed with 100 mL of polyisoprene, molded and dried in an
oven + 90 oC until dry. The mechanical properties (strength
and elasticity) were characterized by bending testing using
Torsee-Tokyo testing machine. Bending strength and elasticity properties stated in the Modulus of Rupture (MOR) and Modulus of Elasticity (MOE). Lignocellulosicfoam density
determined by pycnometer method. Lignocellulosicfoam
morphology observed with a microscope. The results showed blending lignocellulosic and polyisoprene in the preparation lignocellulosicfoam using the stirring method is better than spraying method with optimum conditions at a polyisoprene concentration of 30%. The values of MOR and MOE of lignocellulosicfoam prepared by spraying method at a polyisoprene concentration of 30% was 19.01 g/mm2
and 29.65g/mm2 and stirring method was 52.49 g/mm2
and 64.09 g/mm2.
