摘要:

以3种本体丙烯腈?丁二烯?苯乙烯聚合物(ABS)牌号树脂胶液配比和工艺参数为基准,从橡胶的种类、结构、活性官能团数量、黏度、分子量及其分布等方面进行参照对比,选用1种适合本体ABS合成用国产橡胶,代替专利商指定配方用胶(720AX和565T橡胶),在4釜串联平推流本体ABS小试装置上进行试验。通过对原橡胶与替代橡胶在结构、性能上的差异对比,结合相应ABS树脂的试样性能表征分析,对选用替代橡胶的可行性做出分析和评价。结果表明,国产编号BR?A胶与720AX胶在试验过程中表现的性能差异性较小,可相互替代;国产编号BR?B胶中的1,2?乙烯基含量偏低,橡胶分子量偏大,若替代565T胶,还需进一步进行性能优化。

Abstract:

Based on the proportion and process parameters of three brands of original ABS resin glue solution, the type, structure, quantity of active functional groups, viscosity, and molecular weight and distribution of rubbers were investigated comparatively. A type of domestic rubber suitable for the bulk polymerization of ABS was selected to replace the patent?designated rubber products used in the formula, and the experiment was carried out on a small?scale device equipped with four kettles in series and a horizontal plug flow for the bulk polymerization of ABS. By comparing the structure and properties of the designated rubber products and substitute rubber, the feasibility of selected substitute rubber was and evaluated. The performance of the corresponding ABS resin samples was also analyzed. The results indicated that there was little difference in performance between the domestic BR?A rubber and the designated 720AX rubber, and therefore the designated 720AX rubber could be replaced the domestic one. The content of 1,2?vinyl in the domestic rubber BR?B was lower and its molecular weight was larger compared to the designated one. It is necessary to optimize the performance of domestic rubber BR?B before replacing the designated rubber 565T.
