Quick-drying and repairing refractory material

Abstract

The invention discloses a quick-drying and repairing refractory material. The quick-drying and repairing refractory material comprises the following components in percentage by weight: 40%-80% of aggregate, 10%-25% of powder, 5%-20% of binding agent and 0.2%-4% of additive, wherein the aggregate is one substance or a mixture of more substances in ceramsite, expanded perlite, flint clay, high-alumina bauxite, corundum, light brick sand and heavy brick sand; the powder is a mixture of at least three components in clay, hollow microsphere, closed cell perlite, alumina powder, fine alumina powder, siliceous dust and perlite powder; the binding agent is one substance or a mixture of more substances in high-alumina cement, pure calcium aluminate cement, water glass and a mixture of phosphoric acid and aluminium phosphate as well as phenolic resin; and the additive is one substance or a mixture of three substances in high-efficiency water reducing agent, inorganic phosphate and organic fiber. Compared with the prior art, the quick-drying and repairing refractory material disclosed by the invention has the advantages of good binding performance with the original lining, high temperature rising speed, high intermediate-temperature strength, stable high-temperature volume and strong corrosion resistance and the like.

Description

technical field [0001] The invention relates to a refractory material, in particular to a quick-drying repair refractory material. Background technique [0002] At present, in the petrochemical industry, the linings of the two vessels, the flue, and the heating furnace have to be overhauled every year, and it takes a long time to overhaul the linings of the two vessels. During the overhaul, it takes about a week for the oven to be baked only after the lining is constructed. Therefore, shortening the oven time has become the main research object of lining material manufacturers. In order to meet the needs of high-efficiency production and improve economic benefits, lining manufacturers hope to produce products that can shorten the time for emergency repair and maintenance. my country's technology for refractory materials There are many, but the supplementary materials that can shorten the drying time of the lining of the two vessels have not yet appeared, which can no longer me...
