Abstract

The invention discloses a coal gangue sintered brick and a preparation method thereof. The coal gangue sintered brick is composed of, by weight, 20-25 parts of coal gangue, 2-4 parts of nanometer aluminum oxide, 10-15 parts of large-scale sculpture mud, 8-12 parts of sea mud, 5-10 parts of polyvinyl acetate, 4-6 parts of tung oil, 3-6 parts of waste molasses, 1-2 parts of sodium lauroyl sarcosine, 3-5 parts of abienic balsam, 4-8 parts of asbestos wool, 6-8 parts of additives and a proper amount of water. The sintered brick uses the coal gangue as the main raw material, so that clay resources are saved, production cost is lowered, the treatment problem of the coal gangue is solved, and the pollution to the environment by the coal gangue is avoided. In addition, the sintered brick has the advantages of being high in strength, high in loading capacity, small in density and low in heat conductivity coefficient; the requirements of people are met, the application range is wide, and the market prospect is large. Under the synergistic effect of added antimonous oxide and chlorine elements in chloroprene rubber, the fire resistance of methyl vinyl silicone rubber is enhanced. Due to added dicyclohexyl terephthalate, diisooctyl phenyl phosphite and tetrabromobisphenol A, abrasion resistance, processability and flexibility are improved while the high temperature resistance of silicone rubber is improved.

Description

A kind of coal gangue baked brick and production method thereof

Technical field

The present invention relates to building material technical field, is more particularly a kind of coal gangue baked brick and production method thereof.

Background technology

At present, the mode of vitrified bond during most of brickmaking, is adopted to prepare, but along with the increase of clay produced quantity, clay resource is day by day deficient, not only increase cost of winning, also ecotope is caused to having a strong impact on simultaneously, therefore need badly and optimize and improve existing brick-making method to change the status quo.

Using sodium hydroxide decomposing zircon sand, is the main production that China produces basic zirconium chloride and zirconium dioxide now.China's basic zirconium chloride yearly capacity in 2007 has reached 150,000 t, occupies the first in the world.Demand as the zirconium dioxide of functional materials and structured material also constantly increases, and its production technique cost is lower, but shortcoming is to produce a large amount of wastes (often produce 1t zirconium dioxide product and about discharge sig water 5m3, acid white residue 1t).In recent years, along with production-scale expansion, the process problem of the waste produced in production process also becomes increasingly conspicuous.

Therefore, utilize coal gangue baked brick make vitrified brick be turn waste into wealth, the effective measure of protection of the environment, farmland saving, there is good social and economic benefits.
