Problems solved by technology

At present, domestic foamed glass-ceramics has defects such as low mechanical strength and poor thermal shock resistance, which hinder its application in the fields of construction, heat preservation, heat insulation, and sound insulation; at the same time, heat-resistant metal (alloy steel) molds must be used in the production process , resulting in higher product costs, unstable quality, limited production, and dust pollution in the working environment, which endangers the health of workers; finally, there is still a big gap in terms of solid waste utilization compared with foreign countries.

Abstract

The invention discloses micro-crystallographic foamed glass which is characterized by comprising the following components in percentage by weight: 50% to 70% of coal dust slag, 10% to 20% of waste glass, 8% to 10% of calcium carbonate, 5% to 10% of ceramic fibers and the balance of fluxing agent, nucleation agent and foam stabilizer. According to the micro-crystallographic foamed glass disclosed by the invention, the industrial waste coal dust slag and the waste glass are used as main raw materials and meanwhile, the ceramic fibers are added to be used as a reinforced material, so that quality of a foamed micro-crystallographic glass product can be improved, unit product energy consumption can be reduced, the production scale can be enlarged, labor intensity can be reduced, and the micro-crystallographic foamed glass is beneficial to recycling of waste and has obvious environment-friendly benefits.

Description

technical field [0001] The invention relates to a glass and a preparation method thereof, in particular to a microcrystalline foam glass and a preparation method thereof. Background technique [0002] Foamed glass-ceramic is a new environmentally friendly building material with superior performance in heat insulation, sound absorption, moisture resistance, fire prevention, light weight and high strength. At present, domestic foam glass-ceramics has defects such as low mechanical strength and poor thermal shock resistance, which hinder its application in the fields of construction, heat preservation, heat insulation, and sound insulation; at the same time, heat-resistant metal (alloy steel) molds must be used in the production process , resulting in higher product costs, unstable quality, limited production, and dust pollution in the working environment, which endangers the health of workers; finally, there is still a big gap in terms of solid waste utilization compared with ...
