Abstract

The invention discloses a high-strength light-weight brick and a preparation method of same and belongs to the technical field of building materials. The method includes steps of: 1) heating, stirringand mixing sepiolite and organic acid according to mass ratio of 1:50-1:100, and performing pressure reducing concentration, drying and crushing to prepare modified sepiolite; 2) stirring and mixingfly ash, a cementing material, bauxite, the modified sepiolite, coke, sawdust, gypsum, papermaking black liquid, a sodium fluoride solution, nano iron powder, sludge, fiber granular materials, agar liquid, magnesia, volcanic ash, magnesium chloride and water to prepare mixture slurry; 3) injecting the mixture slurry into a mould, allowing the mould to stand, demolding the mixture, and performing high pressure steam curing to obtain a brick green body; 4) performing nitrogen charging high-temperature sintering to the green body to obtain the high-strength light-weight brick. The high-strength light-weight brick has excellent mechanical performance, thermal shock resistance and heat preservation function; besides, wear resistance is also improved.

Description

technical field [0001] The invention discloses a high-strength lightweight brick and a preparation method thereof, belonging to the technical field of building materials. Background technique [0002] Lightweight bricks generally refer to foam bricks, which are used in normal indoor partition walls, which can effectively reduce the load on the floor and have a good sound insulation effect. The strength products use high-quality platy corundum and mullite as aggregates, sillimanite composite as the matrix, and special additives and a small amount of rare earth oxides are mixed and mixed, and then formed by high pressure and fired at high temperature. Ordinary lightweight heat-insulating refractory bricks are made of clay, high-alumina high-strength floating pearl bricks, low-iron mullite, high-alumina poly light-weight heat-insulating firebricks, and diatomite heat-insulating firebricks. [0003] Although the traditional ceramic tile decoration has many advantages, such as g...
