Problems solved by technology

However, the main use of plastics currently available on the market is not for quick repairs. Therefore, if plastics are used as a solution for quick repairs, the existing performance indicators cannot meet the requirements. It is necessary to adjust the formula of plastics to make it fast. Hardening, micro expansion, high strength, easy to sinter but good high temperature performance, better plasticity and other properties

Abstract

The preparation method comprises the following steps: introducing Li, Ni, Co and Mn into a sagger waste material for calcining a ternary positive electrode material to provide a burning promoter, and effectively adjusting the linear change after burning; a phenolic resin and aluminum dihydrogen phosphate composite binder is adopted, and respective bonding and hardening mechanisms are comprehensively utilized, so that plasticity, viscosity, construction performance, rapid repair and physical properties after hardening are realized; the characteristics that sepiolite and palygorskite are extremely easy to disperse in water and form viscous suspension liquid are utilized, so that the construction performance is improved; the characteristic that sepiolite and palygorskite are rich in magnesium ions is utilized, the hardening effect of sepiolite and palygorskite on aluminum dihydrogen phosphate is achieved, a traditional cement hardening method is replaced, and the purpose of rapid repairing is achieved. The refractory material has a certain micro-expansion effect after burning, can fully fill a damaged part, introduces expanding agents at different temperatures, realizes repair of kiln aluminum-silicon refractory materials at different temperatures, and has wide adaptability.

Description

technical field [0001] The invention belongs to the field of unshaped refractory materials, and in particular relates to an aluminum-silicon quick-repair plastic and a preparation method thereof. Background technique [0002] After the high-temperature kiln has been in operation for a period of time, it is easy to form a certain area and degree of damage locally. If it is not treated in time, it will affect the overall application and efficiency of the kiln, especially the masonry part of the refractory bricks used before the damaged part. The general measures taken at home and abroad are to stop the kiln and replace the refractory material with the same raw material, or repair the abrasive tool with castables at the damaged place, but the above method cleans up the damaged area, the construction intensity is high, and the time is relatively long, which is harmful to the kiln. Furnace operation efficiency is greatly affected, and it has become an industry consensus to find a...
