Environmentally-friendly hollow brick used for buildings and preparation method thereof

Abstract

The invention discloses an environmentally-friendly hollow brick used for buildings. The environmentally-friendly hollow brick is prepared from the following raw materials in parts by weight: 15-25 parts of cement, 25-35 parts of ore tailings, 15-20 parts of purified filler, 3-5 parts of plant powder, 2-4 parts of sulphur powder, 0.5-1.5 parts of nano-zinc oxide, 2-4 parts of glass fiber, 1-2 parts of carbon fiber, 30-40 parts of coal ash, 10-16 parts of emulsion powder and 6-8 parts of industrial mildew preventive. The environmentally-friendly hollow brick used for building decoration has the characteristics of abrasion resistance, high compressive strength, high water absorption, fire prevention and temperature preservation. In addition, the environmentally-friendly hollow brick also has functions of emitting aromatic odor and purifying air, a great quantity of industrial wastes are used as raw materials so as to perform effects on saving energy, reducing emission, preventing environment pollution and being ecological and environmentally friendly. Meanwhile, the preparation method for the hollow brick has the advantages of lower material cost, abundant raw material, simple and clear technology, easiness in operation, easiness in realizing industrial production, higher practical value and good application prospect.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an environment-friendly hollow brick for building and a preparation method thereof. Background technique [0002] Hollow bricks are made of clay, shale, etc. as the main raw materials, after raw material processing, molding, and sintering. The advantages of hollow bricks are light weight, high strength, heat preservation, sound insulation and noise reduction performance. The brick-making industry is an industry with high energy consumption, high pollution, high resource consumption and low output. Every brick and tile factory will receive the key care of the local environmental protection bureau. Now the production of hollow bricks will consume a lot of resources, which is not in line with the principle of resource conservation. , For example, the sintering temperature of most brick and tile factories is about 1300-1400°C, which consumes a lot of energy. In order to ...

Problems solved by technology

Due to the need for sintering, it requires great energy consumption and is easy to pollute the environment

[0003] On the other hand, with the development of the construction industry, the demand for hollow bricks is increasing day by day. The waste of manufacturing traditional hollow bricks will waste a lot of resources such as clay, which is costly and pollutes the environment when firing.
