Abstract

The invention discloses an energy-saving and environmentally-friendly coal gangue lightweight brick. The coal gangue lightweight brick is characterized by being prepared from the following raw materials in parts by weight: 50 to 60 parts of coal gangue, 5 to 7 parts of rice hull, 8 to 9 parts of Portland cement, 6 to 7.5 parts of shale, 11 to 13.5 parts of pumice, 2 to 4 parts of paper pulp waste liquid, 2.5 to 4 parts of sodium sulphide, 4.5 to 6.5 parts of sewage sludge, 2 to 3 parts of borax, 4 to 6 parts of gypsum powder, 7 to 9 parts of a modifier, and a proper amount of water. According to the energy-saving and environmentally-friendly coal gangue lightweight brick, the rice hull, the pumice and other components are added and matched with paper pulp waste liquid and other components with the foaming effect, so that the prepared product is porous, lightweight, and resource-saving; the modifier is added to achieve the light weight, insulation, sound absorbing and bacterium resisting effects, and therefore, the comprehensive performance of the coal gangue brick can be improved. A burning-free process is adopted, so that the coal and other resource wastes can be reduced, sulfur dioxide, hydrogen sulfide and other toxic gases generated by burning can be reduced, and thus, the environmental pollution is reduced. The brick is light, energy-saving, environmentally-friendly, low in water absorbing rate, fast to construct, and high in tensile strength.

Description

Coal gangue light cinder brick of a kind of energy-conserving and environment-protective and preparation method thereof
Technical field
The present invention relates to building material field, coal gangue light cinder brick of particularly a kind of energy-conserving and environment-protective and preparation method thereof.
Background technology
Due to the deterioration of world environments, annual Desertification will be engulfed some and be ploughed; Along with the fast development of economy, city constantly expands.Large stretch of good farmland is used for economic construction, and China's fired clay brick will dig up 25-30 ten thousand mu arable land every year.Land resources crisis has lighted red light.Development green structural material has arrived this stage not allowing to delay.Coal gangue is as one of maximum industrial solid castoff of China's quantity discharged.Add up in the whole nation at present to store up more than 30 hundred million tons, taken up an area about 1.2 × 104 hectares.And the quantity discharged of annual coal gangue is equivalent to about 10% of coal production then.Year discharge rate will be greater than 1.6 hundred million tons.Stack coal gangue and not only take a large amount of soil, and contaminate environment, affect life and the health of people.In addition, often there is spontaneous combustion in coal gangue hill, not only wastes energy, and produce volume of smoke and obnoxious flavour.Also can there is detonation in the coal gangue hill of spontaneous combustion, also can bring out avalanche and landslide under certain conditions, the Architectural Equipment directly near harm and personnel safety.
Employing coal gangue is made building block as main component instead of clay by the present invention, adds the composition that rice husk, float stone etc. are light porous, and coordinate spent pulping liquor etc. to have the composition of foaming effect, the product made has the feature of porous, lightweight; Add the properties-correcting agent that special process is made, there is lightweight, insulation, sound-absorbing, antibacterial effect, enhance the over-all properties of colliery wastes brick; The present invention carries out modification especially in technique, uses unburned technique, reduces the wastings of resources such as coal, reduces the toxic gas such as sulfurous gas, hydrogen sulfide that burning generates, decreases environmental pollution; The technique of compression moulding again, enhances the hardness of fragment of brick, improves mobility, improve workability simultaneously; The non-burning brick lightweight of the present invention, energy-conserving and environment-protective, water-intake rate are low, quick construction, have good tensile strength.
