Abstract
The invention relates to a high temperature resistant air leakage repair material. It mainly solves the technical problems in the prior art that the airtight repairing material loses the plugging function and the repairing life is short due to pyrolysis and volatilization under long-term high-temperature working conditions after repairing operation. The technical solution of the present invention is: a high temperature resistant air leakage repair material, the weight percentage of its raw material components is: 50.1-54.9% of thermosetting resin, 20.1-29.9% of anhydrous resin; 10.3-15.9% of hexamine; aluminum oxide Ultrafine powder 2.1~5.4%, silicon oxide ultrafine powder 3.0~5.5%. The invention is mainly used for repairing air leakage of hot blast stoves.
Description
technical field [0001] The invention relates to a refractory material repairing material, in particular to a high temperature resistant air leakage repairing material. Background technique [0002] There is a certain temperature and a certain pressure in the gas inside the hot blast stove during work. If the sealing is not good, there will be air leakage. Generally, the gas leakage process of the hot blast stove is that the internal gas passes through the steel plate at the bottom of the hot blast stove from the gap between the refractory materials at the bottom of the furnace. The desoldering part of the sealing plate of the grouting hole leaks out, and the escaping gas contains a large amount of gas and harmful gas components, which not only pollutes the atmospheric environment, but also brings great safety hazards to equipment maintenance. In this regard, some companies have used carbon oil to repair, but because the solidification strength of carbon oil is low, its solid...
