Magnesian castable as well as preparation method and application thereof
The invention relates to the field of efficient utilization of resources, and particularly discloses a magnesian castable as well as a preparation method and application thereof. The magnesium castable is prepared from the following raw materials in percentage by weight: 18 to 26 percent of magnesium oxide fine powder, 1 to 3 percent of silicon dioxide micro powder, 1 to 3 percent of magnesium-aluminum-silicon hydrate binding agent, 0.05 to 0.2 percent of polycarboxylate dispersing agent and the balance of magnesium oxide particles. The preparation method comprises the following steps: uniformly mixing the raw material components to obtain a premix, adding 4-6wt% of water into the premix, uniformly mixing to obtain a wet mixture, and finally carrying out pouring and vibration molding on the wet mixture to obtain the castable. The magnesium castable can be used in the fields of magnesium refractory castable, concrete and environment-friendly building materials, and has the advantages of high bonding strength and high breaking strength; in addition, the preparation method has the advantages of being simple in technological process, high in yield, short in period, safe and environmentally friendly.
本申请涉及资源高效利用领域，具体公开了一种镁质浇注料及其制备方法和应用。一种镁质浇注料包括以下原料份：18～26wt％的氧化镁细粉、1～3wt％的二氧化硅微粉、1～3wt％的镁铝硅水合物结合剂、0.05～0.2wt％的聚羧酸盐类分散剂和余量的氧化镁颗粒；其制备方法为：将上述原料组分混合均匀，得到预混料，在预混料中加入4～6wt％的水并混合均匀，得到湿混料，最后将湿混料进行浇注和振动成型，得到浇注料。本申请的镁质浇注料可用于镁质耐火浇注料、混凝土及环保建筑材料领域，其具有结合强度强，抗折强度高的优点；另外，本申请的制备方法具有工艺流程简单、产率高、周期短、安全和环保的优点。
