Abstract
The preparation of foamed building gypsum morta ris to react building gypsum powder with one kind of mixed liquid at 10-15 deg.C under stirring. The said mixed liquid includes sulfuric acid and water. The mixture contains building gypsum powder 55-75.93 wt%, 93 % concentration sulfuric acid 0.03-0.7 wt% and water 25-35 wt% and the sulfuric acid concentration in the mixed liquid is less than 2 %. Foaming with gas CO2 as reaction product rather than foaming machine can simplify equipment and technology and lower preparation cost.
Description
The present invention relates to a kind of preparation method of foamed building gypsum mortar.
Foamed building gypsum mortar is one of building material commonly used in the construction industry, and it is the calcium plaster that building gypsum plaster forms after foaming, and building gypsum plaster refers to that the plaster of paris fires the terra alba that forms.In the making processes of existing foamed building gypsum mortar, use the higher sulfonation ethers tensio-active agent of price, and be equipped with polyvinyl alcohol as stablizer, also must in the high speed whisking machine, stir fast with building gypsum plaster, rotating speed is more than 1500 rev/mins, and making can have abundant inclusion of air wherein, forms the foam slurry passively, this practice makes the cost of manufacture of foamed building gypsum mortar higher, the technology more complicated.
The preparation method who the purpose of this invention is to provide the fairly simple foamed building gypsum mortar of a kind of technology is specially through the preparation method of reaction from the foaming plaster slurry of effervesce.
The preparation method of foamed building gypsum mortar of the present invention comprises building gypsum plaster and a kind of mixed solution is reacted under 10-50 ℃ of temperature, and reaction is to carry out under constantly stirring, and described mixed solution comprises:
(a) 93% vitriol oil
(b) water.
The preparation method of foamed building gypsum mortar of the present invention, contained raw material, press following weight (kilogram) part proportioning:
Building gypsum plaster 55-75 93% vitriol oil 0.03-0.7
Water 25-35
The preparation method of foamed building gypsum mortar of the present invention, in the described mixed solution, pure vitriolic concentration is less than 20 ‰.
The preparation method of foamed building gypsum mortar of the present invention, described stirring is to be that 120-300 rev/min stirrer carries out with rotating speed.Preferable rotating speed is 180-300 rev/min.
The preparation method of foamed building gypsum mortar of the present invention also contains modified starch in the described mixed solution.
The preparation method of foamed building gypsum mortar of the present invention, described building gypsum plaster is at least 60 orders.Be preferably the 60-150 order.
The preparation method of foamed building gypsum mortar of the present invention, under environmental stress, reaction was carried out 0.5-6 minute.
In the preparation method of foamed building gypsum mortar of the present invention, described modified starch is meant starch, as W-Gum, and the starch after calcination process.
The preparation method of foamed building gypsum mortar of the present invention, its advantage is: the major ingredient of building gypsum plaster is a calcium sulfate, contain 1%-5% lime carbonate, behind lime carbonate and the sulfuric acid reaction, generate water, calcium sulfate and carbon dioxide, with the spontaneous foaming of carbon dioxide that generates, replace the quick stirring of high speed whisking machine, adopt general stirrer to stir and get final product, simplified equipment, technology is simple; Save more expensive sulfonation ethers tensio-active agent and polyvinyl alcohol stablizer, preparation cost is reduced; Performance and intensity with the building gypsum mortar of this method preparation are identical with the like product of existing method gained, can be used for further making the foaming plaster decorative sheet, foaming plaster building block or foaming plaster artwork.
Below in conjunction with embodiment, the preparation method of foamed building gypsum mortar of the present invention is described further.
