preparation example Construction

[0032] The invention provides a foam ceramic-ceramic composite integrated brick and a preparation method thereof. The tailings slag of Zhongtiao Mountain and the bottom sludge of the Xunsi River, which destroy the ecological environment, pollute the groundwater quality and occupy a large amount of land resources, are respectively subjected to impurity removal, cleaning, drying, crushing, grinding and screening to obtain two corresponding powders , then add a small amount of calcium carbonate powder (or calcium sulfate, calcium nitrate, etc.) and low-temperature frit powder after the above-mentioned two powders are proportioned according to different mass fractions. The low-temperature frit powder plays the role of fluxing and reducing the sintering temperature during the sintering process; calcium carbonate powder (or calcium sulfate, calcium nitrate and other substances) is easy to foam under high-temperature calcination and can play the role of foaming agent. Add the above b...

Embodiment 1

[0037] (1) Raw material preparation: crush the tailings slag of Zhongtiao Mountain by jaw crusher and send it to Raymond Mill for grinding to obtain 50-100um slag powder, then send it to a special ash storage tank for standby; Cleaning, impurity removal, drying, crushing, grinding, and sieving to obtain 20-50um powder, which is also sent to a special ash storage tank for standby.

[0038] (2) Batch material 1 preparation: the percentage by weight of various raw material ratios is as follows: 65% of Zhongtiaoshan tailings slag powder, 10% of Xunsi river bottom mud powder; 22% of low-temperature frit powder, 3% of industrial calcium nitrate powder %, and then the above-mentioned prepared materials were sent to the ball mill and mixed for 120 minutes to obtain batch one.

[0039] (3) Batch material 2 preparation: the percentage by weight of various raw material ratios is as follows: 67% of Zhongtiaoshan tailings slag powder, 10.3% of Xunsi river bottom mud powder; 22.7% of low-te...

Abstract

The invention discloses a foamed ceramic and ceramic composite integrated brick and a preparation method thereof, wherein mine tailing slag and urban river bottom sludge are used as main raw materials, and are added with a small amount of low-temperature frit and a foaming agent, and proper heat treatment is performed to prepare the foamed ceramic and ceramic composite integrated brick. Accordingto the invention, 90% of the raw materials are all from industrial tailing slag and urban river bottom sludge, so that waste is turned into wealth, no pollution is generated to the environment in theproduction and use process, environmental protection and energy conservation are unified, and the method is an effective method for recycling industrial solid waste and solving environmental pollutionof the industrial solid waste; the produced foamed ceramic-ceramic composite integrated brick has advantages of good adsorption, good water retention, good air permeability, fire resistance and heatresistance, can be directly used for heat insulation of exterior walls, and can avoid the defect of separated construction of heat insulation and water resistance of the traditional exterior wall; andthe preparation process is simple in operation process, low in cost and suitable for industrial large-scale production, and has obvious economic benefits and environmental protection benefits.

Description

technical field [0001] The invention belongs to the technical field of solid waste recycling and relates to a method for recycling fixed waste, in particular to a foam ceramic and ceramic composite integrated brick and a preparation method thereof. Background technique [0002] China's future buildings: Passive house + prefabricated + steel structure = future buildings, among which the construction of green, environmentally friendly and zero-energy passive houses is the basic national policy of the country, that is, the insulation material of the insulation wall should be thick, and all the walls should be made of Insulation materials, so the demand for insulation materials will be greater. Under the demand for a large number of raw materials for insulation materials, the storage capacity of industrial tailings and urban river bottom sludge is more than 5 billion tons, and the number is increasing by 300 million tons per year. The storage capacity of industrial tailings and ...
