Abstract
The invention relates to a low-density and aerated foaming gypsum block. The low-density aerated foaming gypsum block mainly comprises gypsum powder, coal ash, cement, limestone, gas forming agent, calcium carbide, retarders and the like. The low-density aerated foaming gypsum block has the characteristics of low volume density, high strength, light weight, good anti-seismic property, thermal insulation, damp proofing and sound insulation, good workability, fire proofing and flame retardance and the like.
Description
Technical field
The present invention relates to a kind of low close aerating foaming plaster building block, belong to building material field.
Background technology
Gypsum has irreplaceable effect as one of main building cementing material, and its building gypsum products is exactly wherein a kind of, in existing production and the application for many years of China.Yet the volume density of goods is general how big than external same based article, causes the structure of the surperficial hole in plastering inside, hole, pore big, and internal organizational structure is loose, thereby influences its intensity and water resistance.
At present, developed countries adds the whipping agent of some better performances usually when producing building gypsum products, thereby can reduce the volume density of plastering effectively, domestic at present when producing plastering part enterprise also use the aerating whipping agent, but size, quantity, the stability of bubble and the external aerating whipping agent of whipping agent foaming still have a certain distance, and it is because bubble diameter is excessive, bigger to the intensity effect of the plastering after the sclerosis.
Summary of the invention
Purpose of the present invention will provide exactly that a kind of bubble diameter is little, foaming power is strong, stability is good, the low close aerating foaming plaster building block little to intensity effect, thus the building gypsum products volume density effectively reduced, improve the purpose of the comprehensive physical and mechanical property of plaster of Paris.
The present invention is achieved through the following technical solutions: it is characterized in that this low close aerating foaming plaster building block mainly by: terra alba, flyash, cement, Wingdale, foaming agent, carbide of calcium, retardant etc. are formed.
A kind of low close aerating foaming plaster building block by its weight ratio is: terra alba 40～70%; Flyash 20～30%; Cement 10～15%; Wingdale 10～15%; Foaming agent 0.11～0.15%; Carbide of calcium 0.2～0.3%; Retardant 0.15～0.20% composition such as grade.
A kind of low close aerating foaming plaster building block, its foaming agent is: aluminium powder or magnesium powder a kind of; Its retardant is: citric acid.
Embodiment
Take by weighing terra alba 55% by weight; Flyash 25%; Cement 15%; Wingdale 10%; Foaming agent 0.15%; Carbide of calcium 0.2%; Retardant 0.15% is formed.
Its preparation method is:
(1) stirs adding in the suitable quantity of water in the foaming agent input jar.
(2) churning time is 30～40min, and rotating speed is 1500～2000r/min.
(3) under whipped state, drop into solid powder stirring 10～15min and stir.
(4) leave standstill 10min, perfusion model gets final product.
Claims (3)
1. one kind low close aerating foaming plaster building block, this low close aerating foaming plaster building block mainly by: terra alba, flyash, cement, Wingdale, foaming agent, carbide of calcium, retardant etc. are formed.
2. according to the described a kind of low close aerating foaming plaster building block of right 1, by its weight ratio be: terra alba 40～70%; Flyash 20～30%; Cement 10～15%; Wingdale 10～15%; Foaming agent 0.11～0.15%; Carbide of calcium 0.2～0.3%; Retardant 0.15～0.20% composition such as grade.
3. according to right 1,2 described a kind of low close aerating foaming plaster building blocks, its foaming agent is: aluminium powder or magnesium powder a kind of; Its retardant is: citric acid.
