Problems solved by technology

[0002] Because clay bricks will consume a large amount of non-renewable land resources, the construction industry has tried to use sandstone, fly ash, foundry steel slag, etc. Strike a balance between performance, production efficiency and production cost, especially if the overall performance of the product cannot meet the requirements
The existing production process requires calcination and high-pressure steam curing, the process is complex, the process equipment is expensive and the operating cost is high, and a large amount of fuel is consumed during the production process, which is not environmentally friendly

Embodiment 1

[0019] A non-burning and non-steaming titanium gypsum brick, including the following components in mass fraction: 24.5% titanium gypsum, 63% aggregate, 11.5% cement / mineral powder mixture and 1.0% additive, wherein: the additive is no The mixture of sodium sulfate water, alum and curing agent, the aggregate is one or more of industrial slag, gravel and river sand. Among the additives in this embodiment, anhydrous sodium sulfate is mainly used for coagulation, alum is used for disinfection and fermentation, and dihydrate gypsum is used as the solidifying agent. The raw materials of this additive are easy to prepare, and the cost is greatly reduced compared with the existing additives on the market. And the amount of addition is very small, which further reduces the cost of brick making.

[0020] The preparation method of the above-mentioned non-burning and non-steaming titanium gypsum brick comprises the following steps:

[0021] S1, extruding and stirring mud-type titanium gy...

Abstract

The invention discloses a non-fired and non-autoclavedtitanium gypsum brick and a preparation method thereof. The titanium gypsum brickcomprises components in percentage by mass as follows: 24.1%-32.3% of titanium gypsum, 52%-63.8% of aggregate, 11.2%-18.5% of cement / mineral powder and 0.8%-1.0 % of an additive, wherein the additive is a mixture of anhydrous sodium sulfate, alums and a curing agent; and the aggregate is one or more of industrial mineral slag, crushed stone and river sand. The preparation method of the titanium gypsum brick comprises steps as follows: S1, slurry type titanium gypsum is extruded and stirred to form hydraulic slurry; S2, the extruded and smashed titanium gypsum and the aggregate are mixed and stirred for 2-4 minutes; S3, a material prepared in S2 is mixed with the additive and the cement / mineral powder and stirred for 1-3 minutes; S4, extruding forming is performed, consistency of the water content in different positions of a hopper is kept through spraying and watering, and the mass ratio of water to the material prepared in the S3 is 1:(32:40). Raw materials are easy to prepare, main performance parameters meet the national standard, the preparation method is simple and easy to operate, the efficiency is high, energy consumption is reduced due to no need of firing and autoclaving, and environmental pollution is reduced.
