Special low-heat-conductivity and high-strength expanded perlite heat-insulating brick for coke oven and preparation method thereof
The invention relates to the technical field of coke oven construction, in particular to a special low-heat-conductivity and high-strength expanded perlite heat-insulating brick for a coke oven and a preparation method of the special low-heat-conductivity and high-strength expanded perlite heat-insulating brick. Cement and water glass serve as adhesives, expanded perlite serves as aggregate, and the production method comprises the following steps that firstly, the aggregate is screened, and the aggregate with the particle size being 1-4 mm serves as first expanded perlite particles; 0.3-0.8 mm of expanded perlite particles are used as second expanded perlite particles; 2, stirring and mixing an adhesive, wherein the weight ratio of cement to water glass is 30: (2-3); 3, stirring the first expanded perlite, the second expanded perlite, an adhesive and water for forming to obtain a mixture; 4, carrying out compression molding on the mixture in a corresponding mold; and 5, carrying out heat treatment on the formed material to form the hard heat-insulating brick.
本发明涉及焦炉建设的技术领域，特别是涉及一种焦炉专用低导热高强度膨胀珍珠岩隔热砖及其制备方法，其形成具有低导热系数和高强度膨胀系数的珍珠岩隔热砖；以水泥、水玻璃作为粘接剂，膨胀珍珠岩作为骨料，生产步骤如下：第一步、将骨料进行筛分，粒径为1～4mm作为第一膨胀珍珠岩颗粒；0.3～0.8mm作为第二膨胀珍珠岩颗粒；第二步、将粘接剂搅拌混合，其水泥和水玻璃重量配比为30：(2～3)；第三步、将第一膨胀珍珠岩、第二膨胀珍珠岩、粘接剂和水搅拌成型，获得混合料；第四步、将混合料在相应模具内模压成型；第五步、对成型料进行热处理，形成硬质隔热砖。
