Abstract
The invention relates to an expansion agent of magnesium cement product mixed slurry and a method for adding the same. The expansion agent consists of superoxol with the content equal to 50 percent and manganese dioxide with the content equal to 90 percent. Through making use of the characteristic that superoxol can release oxygen in large amounts and adding manganese dioxide as catalyst, the superoxol is stimulated to generate expansion foam quickly; after magnesium cement mixed slurry is added, the expansion foam expands quickly within a final set period till the magnesium cement mixed slurry reaches to final set. Due to adopting an inorganic foam expansion technology to make magnesium cement expansion mixed slurry, the manufacturing technique of magnesium cement product is simplified and the production cost of magnesium cement product is reduced; magnesium cement expansion mixed slurry is used to fill in the apertures between wall plates and between a wall plate and a ceiling for just one time without generating a contraction joint; therefore, the expansion agent not only can be used in an inner wall partition, but also can be safely used in the outer wall body of a building, thereby replacing the prior masonry process, simplifying construction working procedure, accelerating construction progress and reducing construction labor force cost of possession.
Description
Affiliated technical field:
The present invention relates to a kind of swelling agent and adding method of magnesium cement product size mixture, especially a kind of swelling agent and adding method that changes the magnesium cement product size mixture of traditional foam process.
Background technology:
At present, what magnesium cement product adopted is traditional foam process, handy special-purpose foaming mechanism bubble, because foam is lighter, and the magnesium grout is heavier, and foam and magnesium grout are difficult for stirring, to having relatively high expectations of stirrer, and when adding whipping agent, must add stablizer, thereby the goods cost is higher, and the magnesium cement product shrinking percentage that adopts traditional foam process to process is big, is example with the ash wall body plate, can only be used for internal partition wall, and between ash wall body plate and ash wall body plate, be prone to the seam that contracts between ash wall body plate and ceiling, influence construction quality, simultaneously applied limitation is big, is unfavorable for applying.
Summary of the invention:
In order to overcome the deficiency that prior art exists, the invention of this reality provides a kind of swelling agent of magnesium cement product size mixture, use the magnesium cement product of this technology production and can not only manufacture non-bearing magnesium cement products such as inner partition plate, aerated blocks, well lid, and can directly smear seam, fill a vacancy with the cement and expanded mixed slurry of this magnesium, solved the seam problem that contracts.
The present invention solves the technical scheme that its technical problem takes: it is that 50 percent superoxol and content are that 90 percent Manganse Dioxide is formed by content, utilize superoxol can discharge the characteristic of oxygen in large quantities, add Manganse Dioxide again as catalyzer, impel it to produce expanded foam fast, after adding magnesium cement mixing slurry, make it in the final set phase, be expanded to the final set of magnesium cement mixing slurry apace, the method that swelling agent adds mixed slurry is, at first with magnesium oxide and flyash, after the vegetable fibre dry blending stirs, adding magnesium chloride liquid stirs, form magnesium cement mixing slurry, the hydrogen peroxide that accounts for magnesium cement mixing slurry percent nought point four five to one. eight ratios is added in the stirrer, after magnesium cement mixing slurry mixing and stirring, adding accounts for and the Manganse Dioxide of magnesium cement mixing slurry percent zero point zero five to the point two ratio, and the cement and expanded mixed slurry of formation magnesium continues to stir.
The invention has the beneficial effects as follows: owing to adopted inorganic foamed expansion technique to produce the cement and expanded mixed slurry of magnesium, simplified the production technique of magnesium cement product, reduced the production cost of magnesium cement product; Only need between filled wall plate and ash wall body plate with the cement and expanded mixed slurry of magnesium, slit between ash wall body plate and ceiling, do not produce the seam that contracts, thereby not only can also be used for the outer body of wall of buildings safely at interior wall every middle application, replaced existing brick-building art, simplified working procedure, improve construction speed, reduced construction labor force cost of possession, spurred lightweight, the fast development of energy-saving and environmental protection combined wall board.
Description of drawings:
Describing the present invention in detail below in conjunction with accompanying drawing is described further.
Accompanying drawing adds process flow diagram for swelling agent of the present invention
Embodiment:
The specific embodiment of the present invention is: it is that 50 percent superoxol 6 and content are that 90 percent Manganse Dioxide 7 is formed by content, utilize superoxol can discharge the characteristic of oxygen in large quantities, add Manganse Dioxide 7 again as catalyzer, impel it to produce expanded foam fast, after adding magnesium cement mixing slurry, make it in the final set phase, be expanded to the final set of magnesium cement mixing slurry apace, with reference to accompanying drawing, the method that swelling agent adds mixed slurry is, at first with magnesium oxide 1 and flyash 2, after vegetable fibre 3 dry blending stir, adding magnesium chloride liquid 4 bodies stirs, form magnesium cement mixing slurry, the hydrogen peroxide 6 that accounts for magnesium cement mixing slurry percent nought point four five to one. eight ratios is added in the stirrer, after magnesium cement mixing slurry mixing and stirring, adding accounts for and the Manganse Dioxide 7 of magnesium cement mixing slurry percent zero point zero five to the point two ratio, and the cement and expanded mixed slurry 8 of formation magnesium continues to stir.
