Problems solved by technology

However, the unfired bricks directly pressed by dolomite waste slag with a small amount of cement and other additives have the disadvantage of low strength. In order to improve the strength of dolomite waste slag, it is necessary to increase the amount of cement and additives, which greatly increases the production cost and affects the market. application promotion

Abstract

The invention relates to an auxiliary agent for a dolomite waste residue baking-free brick, in particular to an excitant for the dolomite waste residue baking-free brick and a preparation method thereof. The excitant is prepared from the following raw materials in parts by weight: 0.1-1 part of a water reducer, 0.5-2 parts of triisopropanolamine, 1-8 parts of sodium carbonate, 2-5 parts of potassium carbonate, 2-8 parts of diethylene glycol, 0.2-1 part of sodium hydroxide, 1-8 parts of sodium silicate and 80-100 parts of deionized water; the water reducer is a polycarboxylate type high-efficiency water reducer or a naphthalene high-efficiency water reducer. The excitant is added into a dolomite waste residue baking-free brick system to excite the clinker in the raw materials, the production cost of the baking-free brick can be reduced by reducing the use amount of cement, the strength of the brick is improved, and the preparation method of the brick s scientific and reasonable, simpleand feasible, and suitable for industrial production.

Description

technical field [0001] The invention relates to an auxiliary agent for dolomite waste slag unburned bricks, in particular to an activator for dolomite waste slag unburned bricks and a preparation method thereof. Background technique [0002] Dolomite is a sedimentary carbonate rock. It is mainly composed of dolomite, often mixed with quartz, feldspar, calcite and clay minerals, and its appearance is similar to limestone. According to the origin, it can be divided into primary dolomite, diagenetic dolomite and epigenetic dolomite; according to the structure, it can be divided into crystalline dolomite, residual dissimilated particle dolomite, clastic dolomite, microcrystalline dolomite, etc. Dolomite is mainly used as a flux in the iron and steel industry, which can neutralize the acidic slag, increase the alkalinity of the slag, reduce the activity of FeO in the slag, and reduce the erosion of the slag on the lining. At present, my country needs to consume 170kg of dolomit...
