Abstract

The present invention relates to the fireproof material technology field, in particular to a silicon fireproof slurry powder, which is developed to overcome the shortcoming in the prior silicon slurry powder that the material qualities between the raw material for preparing the fireproof slurry powder and the silicon brick for preparing the brick stove body are not similar so as to lead to non-adhesive in the high temperature. The present invention consists of 46-48 percent of silica, 46-48 percent of residue silica brick, 5-7 percent of fireproof clay as well as 0.03-0.05 percent of yellow starch gum. The material qualities between the residue silicon brick and the fireproof slurry powder for the brick stove body are similar; each physical and chemical index of the silicon fireproof slurry powder in the present invention is better than the national standard; by using of the silica and the residue silicon brick with the similar material quality to the silicon brick used for the stove body of the fireproof slurry powder as the main material, the present invention not only realizes the maximum utilization for the waste material, but also the present invention can overcome the shortcomings that the slurry powder and the silicon brick are adhesive in the low temperature but non adhesive in the high temperature. By contraries, the adhesion effect is much greater under the function of yellow starch gum. The present invention can enhance the brick quality for the stove body effectively and prolong the life time for the stove body; the present invention is adaptable to be used in the high temperature stove body for building the heat-air stove, coke stove or glass stove.

Description

technical field [0001] The invention relates to the technical field of refractory materials, in particular to a siliceous refractory mud powder suitable for building blast furnaces such as hot blast stoves, coke ovens and glass kilns. Background technique [0002] Silica mud powder is the bonding material for masonry coke ovens and other high-temperature furnaces, and its performance directly affects the masonry quality and service life of the furnace body. At present, people have been using natural mud. For example, some manufacturers use silica as the main raw material, and then mix it with a small amount of residual silica bricks from various silica brick manufacturers to make natural mud powder. The main raw material is silica, which is different from the silica bricks used in masonry coke ovens and other furnaces. Although the ingredients also contain a small amount of residual silica bricks, due to regional differences, the residual silica used in the preparation of mu...
