Abstract

The invention belongs to the technical field of unshaped refractory materials, and in particular relates to an anti-erosion gunning material. In the present invention, clay, glass fiber, and quartz stone are mixed and sieved to obtain a mixed powder, and then acrylic acid and sodium hydroxide solution are mixed and stirred with mixed powder and sodium dodecylbenzenesulfonate to obtain an emulsified mixed liquid, and the emulsified The mixed solution is reacted with Tween-80, ammonium persulfate, etc. to prepare a binder, and then the graphite, alumina and rice husk are crushed and sieved, and then calcined to obtain a calcined product, which is mixed with zirconium boride, aluminum-magnesium tip After the spar is ball milled and sieved, it is fully stirred evenly with magnesia, high-alumina bauxite, binder, etc. to obtain an anti-erosion gunning material. The gunning material prepared by the present invention has good high-temperature strength, good Volume stability and excellent corrosion resistance make it an ideal material for hot repair of refractory parts.

Description

technical field [0001] The invention belongs to the technical field of unshaped refractory materials, and in particular relates to an anti-erosion gunning material. Background technique [0002] With the development and progress of high-temperature industry, high-temperature production conditions are becoming more and more harsh, which also prompts refractory manufacturers to continuously research and develop low-cost, long-life refractory materials. In the high-temperature production process, local damage caused by uneven erosion of the refractory lining will directly lead to a decrease in the service life of the refractory material and a serious waste of the refractory material. In order to improve the service life of refractory materials and maximize the utilization rate of refractory materials, various hot gunning technologies and gunning materials have emerged as the times require. The gunning material can be directly sprayed on the damaged part of the refractory mater...
