Embodiment 1

[0067] The present invention provides a process for producing foamed microcrystalline thermal insulation decorative panels using fluorite tailings, comprising the following steps:

[0068] (1) Melt the fluorite tailings at high temperature, add modifiers and clarifiers, stir evenly to ensure the melting temperature, the melting temperature is 1500-1550°C, and keep warm for 2 hours;

[0069] (2) The fluorite tailings lava enters the intermediate buffer bag from the molten pool first, and then flows into the water quenching pool from the lower nozzle of the buffer bag for water quenching treatment to form glass particles;

[0070] (3) After the obtained glass-ceramics raw material is ground, screen out glass-ceramic pellets and glass-ceramics powder, add foaming agent calcium carbonate and 1% foaming agent accounting for 2% of the powder mass in the glass-ceramics powder The foam stabilizer borax and fully mixed to obtain a glass-ceramic mixture. The particle size of the glass-...

Abstract

The invention belongs to the inorganic nonmetal material field, relates to a production method of a foam microcrystal thermal insulating decoration board, and specifically relates to a method for producing a foam microcrystal thermal insulating decoration board by use of fluorite tailings. In order to solve the environmental pollution and safety problems caused by the accumulation of fluorite tailings, the invention provides the method for producing the foam microcrystal thermal insulating decoration board by use of fluorite tailings. The quantity of the added fluorite tailings in the method is 50-80%. The method comprises the following steps: (1) conditioning mixing and clarifying mixing; (2) cinder ladle buffering; (3) water quenching of melt; (4) grinding and drying; (5) laying distribution; (6) thermal treatment; at last, the foam microcrystal thermal insulating decoration board can be obtained after cooling. The method has the advantages that the solid waste resource, namely fluorite tailings, is well utilized, and the product microcrystal thermal insulating decoration board has the advantages of high strength, corrosion resistance, fire resistance, thermal insulation and sound insulation properties and the like; as a result, the method is remarkable in economic benefit and environmental protection benefit.

Description

technical field [0001] The invention belongs to the field of inorganic non-metallic materials, and relates to a production method of a foam microcrystal thermal insulation decorative board, in particular to a process method for producing a foam microcrystalline thermal insulation decorative board by using fluorite tailings. Background technique [0002] Fluorite tailings are the solid waste discharged from the concentrator, and the amount is huge, generally several times or even dozens of times that of mine products. At present, the main treatment method adopted in China is to use tailings stockpiles for disposal, which not only requires a lot of manpower and material resources to maintain the operation and management of tailings ponds, but also easily causes environmental pollution and safety accidents. The tailings ponds built require a lot of Land resources, so the recycling of fluorite tailings has always been a research topic at home and abroad. [0003] Microcrystalli...
