【摘要】 以正二十二醇为改性剂对新特能源(TBEA)白炭黑进行有机化改性研究,并将改性产品应用于ABS工程塑料。通过单因素和正交试验得出最优改性条件为:温度120℃,时间8 h,正二十二醇用量25%,催化剂用量4%。此条件下改性产品的吸油值(DBP)为2.15 mL/g,较改性前3.99 mL/g减小46.12%。采用接触角、FT-IR、TG对改性产品进行表征。改性白炭黑/ABS复合材料的冲击强度较未改性白炭黑/ABS复合材料提高了36.2%,较纯ABS提高了75.2%,复合材料分解温度提高了5.0℃。更多还原

【Abstract】 In this paper, behenyl alcohol was chosen as modification agent on TBEA silica’s organic modification and the modified product was applied in ABS engineering plastics. Through the single factor and orthogonal experiment, the best condition of the progress were obtained as follows: temperature was 120 ℃, time was 8 h, the mount of behenyl alcohol was 25%, the mount of catalyst was 4%. In this condition, the DBP of modified product is 2.15 mL/g, decreased 46.12% than 3.99 mL/g before modification. The modified products were characterized by the contact angle, IR, TG. The impact strength of modified silica/ABS composites increased by 36.2% and 75.2% compared to the unmodified silica/ABS composites and the pure ABS, respectively. Decomposition temperature is 5.0 ℃ higher than pure ABS.更多还原
