The invention discloses a strengthening method of a modified microporous thermal insulation board, which comprises the following steps: putting a mixed material into a grinding machine for grinding and mixing, putting the mixed material into an elastic mold to prepare a required board body, feeding the molded board body into a kiln for drying, putting the prepared microporous thermal insulation board into a water vapor environment, and carrying out heating treatment to obtain the modified microporous thermal insulation board. The modified microporous heat insulation plate is obtained. According to the strengthening method of the modified microporous heat insulation plate, the silica powder is subjected to gelatinization reaction through water vapor treatment, the structure of the heat insulation plate is enhanced, the mechanical strength of the heat insulation plate is remarkably improved, and the problem of porosity change caused by direct water contact is also avoided. Meanwhile, a proper amount of alkali metal compound is doped, so that the gelling reaction can be further promoted, and the strengthening effect is better. The method solves the technical problem that an existing micropore heat insulation plate is insufficient in strength, and has good feasibility.

本发明公开了一种改性微孔绝热板的强化方法，将混合物料投入研磨机中研磨混炼，将混炼后的物料装入弹性模具中，制得所需的板体，将成型后的板体送入窑炉中烘干，将制得的微孔绝热板置于水蒸气环境中，进行加热处理，得到改性微孔绝热板。该改性微孔绝热板的强化方法，通过水蒸气处理使硅微粉发生胶凝反应,增强绝热板的结构,显著提高其机械强度,又避免了直接水接触导致孔隙率变化的问题。同时,适量掺入碱金属化合物可以进一步促进胶凝反应,使强化效果更好。该方法改善了现有微孔绝热板强度不足的技术问题,具有良好的可行性。
