Abstract

The invention relates to a nanometer inorganic stone slab using fly ash and a production method thereof. The nanometer inorganic stone slab uses natural stone waste or quartz sand as aggregate, uses apolymer, produced by stimulating the fly ash by a sodium silicate solution, as an inorganic adhesive, and comprises main raw materials of the fly ash, nanometer active micropowder, an alkali silicatesolution, the stone aggregate, an inorganic pigment and the like. The preparation method comprises the following steps: firstly mixing the fly ash, the nanometer active micropowder, the stone aggregate and a toner uniformly by stirring, then adding the sodium silicate solution, stirring uniformly, then dispensing, vibrating under vacuum for compression moulding, curing, polishing, and siliconizing to finally obtain the nanometer inorganic stone slab. The nanometer inorganic stone slab provided by the invention not only has the decorative performance of resin-type artificial stone, but also isnon-toxic and environment-friendly, uses solid waste and is low in cost, resistant to acid and alkali corrosion and resistant to high temperature; in addition, the nanometer inorganic stone slab alsohas the advantages of no deformation, durability, ultraviolet resistance and the like, and is suitable to be used on outdoor occasions.

Description

technical field [0001] The invention relates to the field of comprehensive utilization of solid waste and the field of artificial stone technology, in particular to a nano inorganic stone plate using fly ash and a production method thereof. Background technique [0002] As we all know, the comprehensive utilization of fly ash is an effective way to solve the environmental pollution and safety hazards caused by power plants and smelting enterprises. The proportion of coal-fired power generation in the country is high, and the amount of fly ash produced is very large. Fly ash is an inevitable product of thermal power generation. For every 4 tons of coal consumed, 1 ton of fly ash will be produced. China's thermal power installed capacity has shown explosive growth since 2002, therefore, fly ash emissions have also doubled. According to statistics, the output of fly ash in China has reached 500 million tons; among them, the annual discharge of fly ash in Huainan City, a coal-p...
