Abstract

The invention discloses a coal ash based wood fiber artificial heat retaining panel and a manufacturing method thereof. The heat retaining panel comprises a raw material, a heat retaining material, and a wood panel. The raw material is formed by the materials in the following parts by weight: 100-120 parts of coal ash, 50-60 parts of wood fiber powders, 120-140 parts of water, 5-15 parts of tackifier, 3-10 parts of crack and permeation resistance agent, 5-10 parts of stabilizer, 20-40 parts of kaolinite, and 10-30 parts of lime putty powders. The heat retaining material is a heat insulation coating and an aerogel felt. The wood panel is a wood plate or a wood veneer. The steps of the manufacturing method comprise mixing and stirring, high-temperature sintering, water mill cutting, and sticking facing, etc. The coal ash is used as a base material to be processed into a door sheet, and the door sheet is added with the wood fiber powders, so as to improve tenacity of a coal ash sintered plate, and enhance plasticity and flintiness, and improve use ratio of coal ash. In a manufacturing process, the heat insulation coating and the material are added, effectively improving heat insulation performance of the door sheet. The manufactured coal ash plate effectively absorbs the heat insulation coating, so the heat insulation coating is fully used.

Description

technical field [0001] The invention relates to an artificial board and a manufacturing method thereof, in particular to a fly ash-based wood fiber artificial thermal insulation board and a manufacturing method thereof. Background technique [0002] Fly ash is the fine ash collected from the flue gas after coal combustion. Fly ash is the main solid waste discharged from coal-fired power plants. The main oxide composition of fly ash in thermal power plants in my country is: SiO2, Al2O3, FeO, Fe2O3, CaO, TiO2, etc. Fly ash is one of the largest industrial wastes in my country. With the development of the power industry, the discharge of fly ash from coal-fired power plants is increasing year by year. If a large amount of fly ash is not treated, it will generate dust and pollute the atmosphere; if it is discharged into the water system, it will cause river silting, and the toxic chemicals in it will also cause harm to human beings and organisms. In addition, fly ash can be us...
