Problems solved by technology

[0002] At present, the existing rake-toothed bricks usually use the mud billet raw material in the extrusion molding process, and use the rake-tooth device to scrape the surface of the formed mud billet to form the rake-toothed texture. However, due to the existing mud billet raw materials The clinker particles are usually fired ceramic or sintered brick waste particles such as ceramic waste particles, smoked brick waste particles, split brick waste particles or frosted brick waste particles, to ensure that the strength of the bricks can meet the requirements of the process , but it often leads to the granular polar raw materials formed in the green body after sintering, which are extremely easy to form broken lines and uneven texture distribution when scratching the rake tooth lines, and overlap defects occur, which greatly reduces The decorative effect of the rake-toothed brick surface is finally reduced to a problem of defective products

Abstract

The invention relates to a rake tooth brick without a grain defect and a preparation process thereof. The rake tooth brick comprises the following mud billet raw materials: 50-60 percent by weight ofa plastic clay material, 10-15 percent by weight of vitrified clinker particle, 4-6 percent by weight of high-aluminum clay, 10-20 percent by weight of solvent and 0-10 percent by weight of billet pigment. The rake tooth brick without the grain defect and the preparation process thereof, provided by the invention, have the benefit that not only is the prepared rake tooth brick high in sintering degree and breaking strength, but also continuous, even and dense rake tooth textures can be formed on the brick surface of the rake tooth brick.
