Simplex Lattice Mixture Design

The effect of replacing carbon black (CB) with surfactant-modified natural feldspar (SMNF) on hardness and tensile properties of natural rubber (NR) composites was studied using a simplex-lattice mixture design of experiment. SMNF was produced by treating natural feldspar (NF) with coconut diethanolamine (CDEA) and glycerol monostearate (GMS). Complete replacement of CB with SMNF based from CDEA or GMS decreased Shore A hardness and tensile stress at all elongations. NR composites reinforced with SMNF based from GMS exhibited higher mechanical properties than from CDEA which is attributed to the higher hydrophobicity factor of GMS. CDEA may also have aggregated on the surface of NF, resulting to poor filler dispersion and ineffective stress transfer.

Natural Rubber Composites

Eight kinds of carbon black filled natural rubber composites were prepared, and thermal conductivity was studied. Acetylene black contributes much to the thermal conductivity of rubber, and tiny loading results in considerable improvement. The conductive carbon black 40B2 is advantageous for the improvement in thermal conductivity of rubber when its loading reaches middle level, and at its middle level, also tiny loading results in much improvement. Most kinds of carbon black for rubber application filled rubber composites have good properties except for N134 and N660, especially the poor contribution of N660. Additionally, in the case of carbon black filled rubber composites, addition of filler may not necessarily benefit the thermal conductivity when filler loading is not much.
