There is no waste discharge in the production process of a coal ash geopolymer exterior-wall self-thermal-insulation building block, so the building block is a very environmentally-friendly thermal insulation material.
Description
Technical field
The invention belongs to field of material engineering technology, relate to a kind of flyash geopolymer heat insulation building block and manufacturing process.
Background technology
China's construction unit area energy consumption is still 3～5 times of the close developed country of weather.Along with deepening continuously of China's dwelling construction energy conservation, the building energy conservation mode of exterior wall self-heat conserving is day by day popularized.More existing self-thermal insulation materials are mostly on the basis of inorganic materials, fill some organic class lagging materials in inside, and this makes its fire resistance reduce greatly, and inner organism is easily aging, contraction has reduced heat-insulating property; The inorganic self-heat conserving product heat retaining property difference and the intensity of single-material are low, can not satisfy the further energy-conservation requirement of country.
Existing several self-thermal insulation materials have the following disadvantages respectively:
1. concrete composite thermal self-insulation building block and sintered combined heat insulation building block: the inner organic insulation material of filling mostly, fire line is poor; Inner organism also shrinks easily, aging, along with the growth heat retaining property of duration of service reduces gradually, do not satisfy national growing building energy conservation requirement.2. foamed concrete heat insulation building block: intensity is low, heat retaining property difference etc., many performances even less than common autoclaved aerated building block.3. many rounds of flyash heat insulation building block: heat retaining property is poor, does not satisfy national growing building energy conservation requirement.
Summary of the invention
The objective of the invention is to produce a kind of flyash geopolymer heat insulation building block, to solve problems such as existing lagging material fire resistance is low, security is low, heat retaining property is poor, work-ing life is short, cost is high, seriously polluted, and utilize refuse flyash, breeze, reduce a series of environmental problems that flyash, breeze brought.
The technical solution adopted in the present invention is to utilize the pozzolanic activity of flyash and breeze, under the exciting of alkali-activator, makes a kind of flyash geopolymer heat insulation building block through foaming, maintenance.Its raw material is formed partition ratio: flyash 60%-95%, mixing excitation agent X4%-30%, slag micropowder 0.01%-25%, suds-stabilizing agent 0.3%-5%.Described mixing excitation agent X is a kind of mixed solution that contains different kinds of ions and active material of alkalescence.
The processing step of making flyash geopolymer heat insulation building block is as follows:
1, slurrying: the clear water that in stirrer, adds 10-70 ℃, water cement ratio (ratio of water and flyash, the two weight sum of slag micropowder) is 1/3-1.3/1, presses the above-mentioned raw materials proportioning, and various starting material are added in the stirrer, stirred 3-15 minute, it is stirred.
2, foaming: add hydrogen peroxide, hydrogen peroxide and gray scale (ratio of hydrogen peroxide and flyash, the two weight sum of slag micropowder) are 25/1000-80/1000, stir 1-10 minute, slurry are put into mould, static 1-10 hour.
3, steam-cured: the slurry that foaming is stopped was with 50-120 ℃ the steam-cured 0.5-7 of water vapor days.
4, cutting: hardened bulk slurry cuts into the thickness and the size of customer requirement.
5, the examination and test of products: reject inferior product, obtain flyash geopolymer heat insulation building block qualified product.
Adopt positively effect of the present invention to be: the exterior wall self-thermal insulation material made from the flyash geopolymer has that freeze-thaw resistance is strong, thermal conductivity is low, with same life-span of building, good waterproof performance, advantages of high strength, and can utilize trade wastes such as refuse flyash, slag micropowder.Not having the discharging of refuse in this flyash geopolymer exterior wall self-thermal insulation material production process, is a kind of lagging material of very environmental protection.Therefore, this product not only performance surmounts other like product, and the protection environment is highly profitable.
