Preparation method of magnesium-calcium ramming liquid binding agent
The invention relates to the technical field of chemical production and discloses a preparation method of a magnesium-calcium ramming liquid binding agent. The magnesium-calcium ramming liquid bindingagent is a dimethicone binding agent, and the preparation method specifically comprises the following steps: S1, taking a metal silicon block, putting the metal silicon block into a ball mill, and grinding to obtain metal silicon powder; and S2, putting the metal silicon powder into a reaction kettle, adding chloromethane gas and a catalyst into the reaction kettle, performing high-temperature catalysis, and vacuumizing the reaction kettle to keep the vacuum degree at 404-504kPa to obtain a dimethyl dichlorosilane liquid for later use. The preparation method provided by the invention is simple and clear in preparation steps, convenient to operate and high in preparation efficiency, the prepared dimethicone binding agent does not need to be added with water during use, a magnesium-calciumramming material can be effectively protected against hydration, the product quality is improved, and compared with a conventional binding agent, the dimethicone binding agent is more convenient to construct and does not need to be stirred, and the product construction efficiency is improved.
本发明涉及化工生产技术领域，且公开了一种镁钙捣打液态结合剂制备方法，所述镁钙捣打液态结合剂为二甲基硅油结合剂，具体制备方法如下：S1取金属硅块投入球磨机内进行研磨，得到金属硅粉；S2将上述金属硅粉投入一个反应釜内，向反应釜内添加氯甲烷气体和催化剂，高温催化，同时对反应釜内抽真空，使真空度保持在404‑504kPa，得到二甲基二氯硅烷液体，备用。本发明所提供的制备方法，制备步骤简单明了，操作方便，制备效率高，制备所得的二甲基硅油结合剂在使用时，无需外加水，能够有效保护镁钙捣打料不发生水化，提高产品质量，相比常规结合剂，施工更加方便，无需搅拌，提高产品施工效率。
