Problems solved by technology

Refractory bricks are high-temperature refractory materials. Most of the refractory bricks currently on the market are used in high-temperature firing furnaces, and are not suitable for high-temperature furnaces that operate outdoors in harsh environments. The performance and seismic stability are not ideal, and its service life is short, which not only wastes resources, but also increases costs

Embodiment 1

[0027] This embodiment relates to a high-temperature refractory brick and its preparation method;

[0028] The high temperature refractory brick is prepared from the following components:

[0029] 40 parts of magnesite, 10 parts of quartz powder, 16 parts of high-alumina bauxite clinker, 15 parts of high-viscosity attapulgite clay, 12 parts of calcium silicate cement, 13 parts of alumina, 7 parts of diatomite, 12 parts of glass waste 9 parts, 9 parts of polyisocyanurate foam plastics.

[0030] Wherein, the high-viscosity attapulgite clay is a purified and activated product of natural attapulgite clay. On the one hand, its high-viscosity property greatly improves the bonding performance of the mixed material, thereby greatly increasing the strength of the brick body, avoiding the situation of conventional brick body chipping, and on the other hand, due to the characteristics of the attapulgite clay itself, the material It has the performance of high temperature resistance and...

Embodiment 2

[0041] This embodiment relates to a high-temperature refractory brick and its preparation method;

[0042] The high temperature refractory brick is prepared from the following components:

[0043] 38 parts of magnesite, 8 parts of quartz powder, 14 parts of high-alumina bauxite clinker, 13 parts of high-viscosity attapulgite clay, 10 parts of calcium silicate cement, 15 parts of alumina, 6 parts of diatomite, and 10 parts of glass waste Parts, 12 parts of polyisocyanurate foam plastics.

[0044] Wherein, the high-viscosity attapulgite clay is a purified and activated product of natural attapulgite clay. On the one hand, its high-viscosity property greatly improves the bonding performance of the mixed material, thereby greatly increasing the strength of the brick body, avoiding the situation of conventional brick body chipping, and on the other hand, due to the characteristics of the attapulgite clay itself, the material It has the performance of high temperature resistance a...

Embodiment 3

[0055] This embodiment relates to a high-temperature refractory brick and its preparation method;

Abstract

The invention provides a high-temperature refractory brick and a production method thereof. The refractory brick comprises the following components: magnesite, quartz powder, high bauxitic clay clinker, high viscosity attapulgite clay, calcium silicate cement, alumina, diatomite, glass waste residue, and polyisocyanurate foam plastic. The preparation method comprises the following steps: crushingthe components, mixing the components according to a sequence, and performing steps of moulding, drying and sintering to obtain the high-temperature refractory brick. The high-temperature refractory brick has good heat stability, mechanical strength and wear resistance, good shock resistance, and good application prospect, and greatly prolongs the usage life of the refractory brick.

Description

technical field [0001] The invention relates to the technical field of refractory material processing, in particular to a high-temperature refractory brick and a preparation method thereof. Background technique [0002] Refractory bricks are refractory materials with certain shapes and sizes. According to the size, refractory bricks can be divided into standard bricks, ordinary bricks and special bricks, etc., which can be used in building kilns, ordinary annealing furnaces and high-temperature building materials of various thermal equipment, and can withstand various physical and chemical properties at high temperatures. Chemical change and mechanical action. Refractory bricks are high-temperature refractory materials. Most of the refractory bricks currently on the market are used in high-temperature firing furnaces, and are not suitable for high-temperature furnaces that operate outdoors in harsh environments. The performance and anti-seismic stability are not ideal, and...
