Clay checker brick and preparation method thereof

Abstract

The invention provides a clay checker brick which comprises a main material and a binder; the clay checker brick is characterized in that the main material comprises the following raw materials by the mass percentage: 38%-42% of large clay clinker particles with the particle size of 1.0 mm-2.0 mm, 23%-28% of small clay clinker particles, and 32%-38% of a clay micro-powder; the clay micro-powder is composed of a clay clinker micro-powder and a soft clay micro-powder with the mass ratio of 1:(1-3); the mass of the binder is 2.0%-4.5% of the mass of the main material; and the volume density of the main material is greater than 2.50 g / cm<3>. The clay checker brick has relatively high matrix performance consistency and relatively low apparent porosity. The invention provides a preparation method of the clay checker brick, wherein the preparation method comprises the steps of preparation of a brick blank and drying and sintering. The preparation method has the advantages of simple steps and easy realization of automatic production, and reduces production costs.

Description

technical field [0001] The invention belongs to the field of refractory materials, and in particular relates to a clay lattice brick and a preparation method thereof. Background technique [0002] Clay checker bricks are specific products, which can be divided into flat bricks and convex bricks according to the shape of the two sides. The traditional process of producing clay checker bricks usually requires a lot of manpower and material resources, the level of automation is not high, and the production efficiency is low. When using the automatic brick making machine to produce clay checker bricks, there are special requirements for the ratio of the raw materials of the clay checker bricks. Among them, when using the automatic brick making machine and using the raw material ratio and pressure of the traditional process to press the convex brick of the clay checker brick, due to the uneven force on the upper and lower surfaces of the checker brick, the density of the pressed ...

Problems solved by technology

Among them, when using the automatic brick making machine and using the raw material ratio and pressure of the traditional process to press the convex brick of the clay checker brick, due to the uneven force on the upper and lower surfaces of the checker brick, the density of the pressed product is different, and the product will appear pockmarked. , Concave unevenness, etc., which seriously affect the appearance. In addition, due to the frequent pitting of the corners, the kiln is often crushed and the pass rate is low.
