Problems solved by technology

Generally, sintering and solidification are often used. This process not only requires a large amount of coal resources, but also has many factors that affect the solidification quality, such as: moisture content, preheating temperature, sintering temperature, sintering time, cooling time, etc. The process is complex. There are many controllable parameters, and the quality is difficult to guarantee

Abstract

The invention discloses a burn-free heat-insulation external tile produced from gangue. The burn-free heat-insulation external tile is produced from the following raw materials in percentage by weight: 40-63 percent of gangue, 2-9 percent of cement, 15-32 percent of a binding agent, 3-9 percent of adhesive, 0.05-1 percent of water reducer, 0.45-3 percent of an initiator, 2-15 percent of foams for foaming and 1.5-4 percent of an accelerant. In addition, the invention also provides a production method of the burn-free heat-insulation external tile produced from gangue. The heat-insulation external tile is free of burning, easily realizes batch production, has excellent safety performance and is environmental friendly, the energy source is saved, the production cost is reduced, the waste gangue is comprehensively utilized, and the land occupied by stacking the gangue is reduced; the produced heat-insulation external tile has the advantages of light weight, high strength, low cost and the like and makes a contribution to the development of building heat-insulation materials in China.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a coal gangue non-fired thermal insulation exterior wall brick and a production method thereof. Background technique [0002] At present, my country's building insulation materials mostly use relatively mature organic insulation materials such as expanded polystyrene board (EPS board), extruded polystyrene board (XPS board), rubber powder polystyrene particle insulation mortar material, and polyurethane foam material. At present, this kind of material is basically used in external wall insulation, and its early thermal insulation effect is also good. However, due to the inherent defects of organic thermal insulation materials, there are fatal weaknesses. The first is its safety performance. Due to the flammability of organic insulation materials, once a fire breaks out, it is likely to cause the fire to spread rapidly along the facade. The second is the ...
