Problems solved by technology

However, due to the presence of a certain amount of sulfur in calcium lignosulfonate, SO2 will be released during the firing process, resulting in a high SO2 content in the flue gas and a pungent smell, which affects the daily life of the surrounding residents to a certain extent. Pollution to the environment, does not conform to the production concept of "zero emission"

Abstract

The invention discloses a bonding agent for basic refractory materials and a method for preparing the bonding agent, and belongs to the field of refractory materials. The bonding agent for the refractory materials comprises, by weight, 50-90% of industrial glucose syrup, 10-30% of dextrin and 10-20% of industrial carboxymethyl celluloses. The bonding agent and the method have the advantages that the bonding agent is environmentally friendly, is free of pollution or sulfur, is free of residues after being burnt, and conforms to 'zero emission' industrial production concepts; the bonding agent is high in adhesion property, basic refractory green bricks produced by the aid of the bonding agent are high in strength, the shortcomings of edge missing and corner falling of existing basic refractory green bricks can be overcome, automatic brick clamping and stacking requirements on manipulators in actual production procedures can be met, and waste bricks can be reduced.

Description

technical field [0001] The invention relates to the field of refractory materials, in particular to a binder for basic refractory materials and a preparation method thereof. Background technique [0002] At present, the binder used in the production process of alkaline refractories is generally sulfurous acid pulp waste liquid (calcium lignosulfonate solution), which has the advantages of low cost, good bonding performance, high brick strength, and less impact on the performance of finished bricks. Small and other advantages. However, due to the presence of a certain amount of sulfur in calcium lignosulfonate, SO2 will be released during the firing process, resulting in a high SO2 content in the flue gas and a pungent smell, which affects the daily life of the surrounding residents to a certain extent. It causes pollution to the environment and does not conform to the production concept of "zero emission". [0003] Industrial glucose syrup, dextrin and industrial carboxyme...
