Embodiment 1

[0025] A high-strength wall brick is made by mixing clay, auxiliary materials and iron ore waste slag with water, wherein the weight of auxiliary materials and iron ore waste slag is 30% and 10% of the clay weight respectively.

[0026] The auxiliary material is formed by mixing rosin and calcium carbonate particles with a fineness of 8-20 mesh at a weight ratio of 1:30.

[0027] The preparation method of above-mentioned high-strength wall brick comprises the following steps:

[0028] Step 1, preparation of excipients

[0029] Heat and melt the rosin, then add it into calcium carbonate particles with a fineness of 8-20 mesh and stir to mix evenly. The weight ratio of rosin to calcium carbonate is 1:30;

[0030] Step 2. Mix the auxiliary materials prepared in step 1 with clay and iron ore waste slag according to the above ratio, add an appropriate amount of water and stir to make mud, and then make a green body for future use;

[0031] Step 3. Dry the green body and send it t...

Abstract

The invention discloses a high-strength wall brick and a preparation method thereof. The high-strength wall brick is prepared from clay, an auxiliary material and an iron mine waste residue in a manner of firing after adding water to mix, wherein the weights of the auxiliary material and the iron mine waste residue respectively are 30-50% and 10-20% of that of the clay; the auxiliary material is prepared from rosin and calcium carbonate particles of which the fineness is 8-20 meshes in a mixing manner according to the weight ratio of 1:(30-50). The wall brick produced by using the residual iron mine waste residue after iron mine excavation, so that not only is consumption of the clay reduced, but also the iron mine waste residue is fully utilized, the weight of the produced wall brick is reduced due to high porosity in the internal part, but the strength is greatly improved due to the action of a sintering phase generated when the wall brick is sintered in the internal part, and meanwhile, the surface has a certain gap, so that the high-strength wall brick has a certain function of absorbing noise.

Description

technical field [0001] The invention relates to building materials used in the construction field, in particular to a high-strength wall brick and a preparation method thereof. Background technique [0002] In the prior art, the production of wall bricks used for building houses generally has the following steps: digging out the soil and mixing it with water to form it, and sending the green body into a kiln for firing after drying in the shade. Due to the rapid development of the real estate industry, the demand for wall tiles has also increased rapidly. However, a large number of wall bricks are fired with clay, which leads to the reduction of cultivated land resources, and the strength of the produced wall bricks is poor, and it is easy to be damaged if it bears a large weight. Contents of the invention [0003] In order to solve the problem of low strength of wall bricks in the prior art, the present invention provides a high-strength wall brick and its preparation me...
