New method for producing carbon foam from recycled carbon (NEWCAFO)

Abstract

The aim of the study was to define a new method (SENAY process) for carbon foam (CF) production following curing by mixing organic materials with high-volatile content only with acrylic resins. In the study, carbon foam was produced by calcining after curing in water-based acrylic resins (styrene acrylic copolymer (SAC) and vinyl acrylic copolymer (VAC)) and recycled carbon (RC) obtained from decomposed waste tire. The amount of RC (3-5 g), SAC: VAC ratio (5:0-0:5), temperature (400-900 degrees C), and time (30-240 min) were selected as parameters. Carbon foams were characterized by porosity tests and FT-IR (Fourier transform infrared spectrophotometer), SEM (scanning electron microscope), TEM (transmission electron microscope), and BET (Brunauer-Emmett-Teller) analysis. The porosity values of CF-1: 1, CF-1: 3, and CF-0: 5 carbon foams were 75.71, 79, and 97%, respectively. Porosity value was 97% due to the micropores and nanoparticles seen in the bonds of CF-0:5 where only VAC was used. As a result, a simple and cost-effective new method for carbon foam production has been verified as a result of curing by mixing organic materials with high-volatile matter content and only acrylic resins without using pressure and stabilization steps. At the same time, a new area where waste tire can be utilized in the production of carbon foam has been demonstrated. [GRAPHICS] .
