Brick for fireplace and preparation method of brick

Abstract

The invention discloses a brick for a fireplace. The brick comprises 10-30% of magnesite powder, 5-10% of dolomite powder, 5-20% of quartz sand, 5-20% of plant stalk powder, 25-40% of residual soil and garbage powder, 2-15% of a binding agent, 0.3-3% of a curing agent and 5-15% of cement. The invention also provides a preparation method of the brick for the fireplace. The brick has the advantages that the raw materials of the brick are adopted, so that waste recovery can be realized, the aim of changing waste materials into things of value can be achieved, the area of land occupied by garbage in a city can be reduced, and the surrounding environment of the city can be improved; in addition, no any poisonous substances are discharged after the brick is molded, so that the environment is protected; meanwhile, the heat resistance of the material is relatively good, so that the heat-resistant requirement of the fireplace is met; and the process steps of the preparation method are relatively simple, and the quality of the obtained product is relatively good.
