Unfired alumina-magnesia carbon brick and preparation method thereof
The invention provides an unfired alumina-magnesia-carbon brick and a preparation method thereof, relates to the technical field of unfired alumina-magnesia-carbon bricks, and solves the problem that an asphalt substance is used as a binding agent in the production of the existing unfired alumina-magnesia-carbon brick to affect a user and the environment, the unfired alumina-magnesia-carbon brick comprises the following components: 65-75 parts of alumina, 80-100 parts of capacitor magnesia, 2-5 parts of silicon powder, 2-4 parts of synthetic resin and 5-8 parts of graphite, the invention relates to a high-strength and high-toughness refractory material which is composed of the following components: 66 parts of alumina, 85 parts of capacitance magnesia, 3 parts of silicon powder, 3 parts of synthetic resin and 6 parts of graphite, the grain granularity of the capacitance magnesia is 80-85 microns, and the magnesium content of the capacitance magnesia is one of 96.5%, 97.5% and 98%. According to the invention, the synthetic resin is added and combined, the synthetic resin is prepared by reacting phenol and formaldehyde, can be well mixed with refractory material particles at normal temperature, has high residual carbon rate after carbonization, does not contain cancerogenic substances, and is beneficial to environmental protection.
本发明提供一种不烧铝镁碳砖及其制备方法，涉及不烧铝镁碳砖技术领域，解决了现在的不烧铝镁碳砖生产使用沥青类物质做为结合剂，对使用者和环境造成影响的问题，由如下组分组成：矾土65～75份，电容镁砂80～100份，硅粉2～5份，合成树脂2～4份，石墨5～8份，由如下组分组成：矾土66份，电容镁砂85份，硅粉3份，合成树脂3份，石墨6份，电容镁砂的晶粒颗粒度为80μm～85μm，电容镁砂的含镁量为96.5％、97.5％、98％中的一种。该发明通过添加合成树脂对其结合，合成树脂是由苯酚和甲醛反应制得，在常温下便能和耐火材料颗粒很好的混合，炭化后残碳率高，并且合成树脂内部不含有致癌物质，有利于对环境的保护。
