Abstract:Chemical modified desulfurization ash/styrene butadiene rubber composite materials were prepared using chemical modified desulfurization ash replacing partial carbon black,BP neural network optimization model of preparation process parameters (amounts of accelerator, sulfur, amount of stearic acid, and zinc oxide and curing time) and mechanical properties were established by uniform design in a combination with BP neural network to acquire parameter of optimal chemical modified desulfurization ash/styrene butadiene rubber composite materials. Tensile properties of chemical modified desulfurization ash/styrene butadiene rubber composite materials were tested by referring to rubber, vulcanized or thermoplastic-determination of tensile stress-strain properties, tear strength of chemical modified desulfurization ash/styrene butadiene rubber composite materials were tested by referring to rubber, vulcanized or thermoplastic-determination of tear strength, hardness of chemical modified desulfurization ash/styrene butadiene rubber composite materials was tested by referring to rubber, vulcanized or thermoplastic-determination of indentation hardness, Duromerer method (Shore hardness) (trouser, angle and crecent test pieces). Microstructure of optimal chemical modified desulfurization ash/styrene butadiene rubber composite materials were observed by SEM, mineral composition of optimal chemical modified desulfurization ash/styrene butadiene rubber composite materials were analyzed by XRD. The results showed that the parameters of optimal chemical modified desulfurization ash/styrene butadiene rubber composite materials were amount of accelerator 1.2 g, amount of sulfur 1.3 g, amount of stearic acid 1.1 g, amount of zinc oxide 2.4 g and curing time 27 min. Mechanical properties of optimal chemical modified desulfurization ash/styrene butadiene rubber composite materials were tensile strength 20.31 MPa, tear strength 45.68 kN/m and Shore A hardness 66. The optimal measured values and the model optimal predictive values were in good agreement, the relative error was 3.03%?3.22%. The above research provides technical support and theoretical basis for the development of cheap inorganic filler which can replace partial carbon black.
