一种浇注料用有机-无机复合结合剂及其制备方法
摘要：
本发明具体涉及一种浇注料用有机-无机复合结合剂及其制备方法。所采用的技术方案是：5.76～14.4wt％的丙烯酰胺、0.2～0.6wt％的N-N′-亚甲基双丙烯酰胺、0.03～0.30wt％的过硫酸铵、0.005～0.1wt％的四甲基乙二胺配合物、70.8～78.5wt％的硅微粉和14.0～15.5wt％的氧化铝微粉混合，然后分袋包装。其中，四甲基乙二胺配合物为氯化亚铜的甲醇溶液在氧气气氛下与N，N，N’，N’-四甲基乙二胺(TMEDA)反应形成四甲基乙二胺的碱式氯化铜配合物[Cu(OH)Cl·TMEDA]。本发明具有工艺简单、适用范围广的特点；所制备的结合剂用于浇注料脱模时间缩短，烘烤后强度明显增大，方便了生产施工，提高了工作效率。
摘要（英）：

The invention specifically relates to an organic-inorganic composite binder for casting materials and a preparation method thereof. The adopted technical proposal is as follows: 5.76 to 14.4 percent by weight of acrylamide, 0.2 to 0.6 percent by weight of N-N'-methylene-bis-acrylamide, 0.03 to 0.30 percent by weight of ammonium persulfate, 0.005 to 0.1 percent by weight of tetramethylethylenediamine complex, 70.8 to 78.5 percent by weight of silicon micro-powder, 14.0 to 15.5 percent by weight of alumina micro-powder are mixed and then packaged by bags.Wherein, the tetramethylethylenediamine complex is basic cupric chloride complex (Cu(OH)Cl.TMEDA) of tetramethylethylenediamine which is formed by carrying out the reaction of methanol solution of copper chloride and N, N, N', N'-tetramethylethylenediamine (TMEDA) under the oxygen atmosphere. The preparation method is characterized by simple process and wide application range; the prepared binder can shorten the stripping time, significantly increase the strength after the baking, facilitate the production and the construction and improve the working efficiency when the binder is used for the casting materials.
