Problems solved by technology

[0002] For the bonding of wear-resistant products used in fluidized bed boilers and bricks and bricks in masonry, not only must they be firmly bonded, but also have a certain flexural compressive strength and bonding strength. Most of the currently used adhesives are not very good. Good to meet the requirements, for this situation it is necessary to develop a multi-functional wear-resistant refractory adhesive to solve the above problems

Abstract

The invention discloses multifunctional wear-resistant fireproof adhesive and a production method thereof and belongs to the technical field of irregular fireproof castables. The multifunctional wear-resistant fireproof adhesive and the production method thereof according to the technical scheme are characterized in that the multifunctional wear-resistant fireproof adhesive is prepared from, by weight, 35-45 parts of phosphoric acid solution having a mass concentration of 85%, 15-25 parts of sulfuric acid solution having a mass concentration of 50%, 3-5 parts of alumina micropowder, 20-30 parts of corundum micropowder, 30-50 parts of high-aluminum micropowder, 10-20 parts of clay, 5-7 parts of aluminum hydroxide, 30-40 parts of water, and 1-3 parts of an oxalic acid inhibitor. The invention also particularly discloses a production method of the multifunctional wear-resistant fireproof adhesive. The multifunctional wear-resistant fireproof adhesive produced herein is suitable for adhesion of various wear-resistant articles and heat-resistant parts, has high adhesive strength and flexural and compressive strength, and the problems are effectively solved, for example, a lining of a fluidized-bed steel furnace has long maintenance time.

Description

technical field [0001] The invention belongs to the technical field of unshaped refractory castables, and in particular relates to a multifunctional wear-resistant and refractory adhesive and a production method thereof. Background technique [0002] For the bonding of wear-resistant products used in fluidized bed boilers and bricks and bricks in masonry, not only must they be firmly bonded, but also have a certain flexural compressive strength and bonding strength. Most of the currently used adhesives are not very good. To meet the requirements well, it is necessary to develop a multifunctional wear-resistant and refractory adhesive to solve the above problems in view of this situation. Contents of the invention [0003] The technical problem solved by the present invention is to provide a multifunctional wear-resistant and refractory adhesive and its production method. The adhesive can not only bond wear-resistant part. [0004] In order to solve the above technical pr...
