Description
Technical field
The present invention relates to wall plastering field of material technology, especially a kind of wall plastering gypsum compositions and its preparation side
Method.
Background technology
Tradition paints the powder of lacquer putty for use on that wall uses, mainly with methylcellulose, carboxymethyl cellulose or starch etc
After rubber powder and land plaster, dry powder, talcum powder, light calcium carbonate powder, sierozem power etc. are dry-mixed, the one pack system solid powder that is made into；Solve
The randomness for dispensing of constructing so that in use, only needing that powder putty powder is modulated into paste with water according to a certain percentage.Can
It is that in use, it easily plays powder, come off this kind of product, and surface strength, adhesive strength are all very low, have a strong impact on
The quality of putty.
The raw material and proportioning of wall plastering gypsum compositions are studied in consideration of it, this researcher passes through, passed through
Rational proportion design, the improvement to wall plastering gypsum compositions quality is realized, improve quality, improve wall plastering process
In surface strength and adhesive strength, provide a kind of new approaches for wall plastering technical field.
The content of the invention
In order to solve above-mentioned technical problem present in prior art, the present invention provides a kind of wall plastering gypsum compositions
And preparation method thereof.
It is achieved particular by following technical scheme：
A kind of wall plastering gypsum compositions, material composition are desulfurated plaster 1-1000 parts in parts by weight, PO42.5 water
Mud 50-300 parts, it is redispersable latex powder 1-5 parts, flyash 100-500 parts, cellulose 1-10 parts, starch ether 0.1-3 parts, slow
Solidifying agent 1-3 parts.
Described material composition is in parts by weight desulfurated plaster 50-900 parts, PO42.5 cement 100-200 parts, can be divided again
Dissipate latex powder 2-4 parts, flyash 200-400 parts, cellulose 3-8 parts, starch ether 1-3 parts, retarder 1-3 parts.
Described material composition is 700 parts of desulfurated plaster in parts by weight, 100 parts of PO42.5 cement, Redispersable latex
2.5 parts of powder, 230 parts of flyash, 3 parts of cellulose, 0.8 part of starch ether, 1.5 parts of retarder.
Described PO42.5 cement is PO42.5 Portland cements.
Described desulfurated plaster particle diameter is 130-150 mesh.
Described flyash is one-level flyash and/or second class powered coal ash.
Described flyash particle diameter is 130-150 mesh.
Above-mentioned wall plastering gypsum compositions preparation method, comprises the following steps：
(1) raw material is weighed；
(2) raw material weighed is poured into container and mixed, and using hand blender stirring 10min, mixing speed can not
Come so that material sputters；
(3) material for obtaining step (2) when in use, adds appropriate water thereto, after stirring, stands
3min, it is again stirring for, you can use.
Compared with prior art, the technique effect of the invention is embodied in：
By by desulfurated plaster, PO42.5 cement, redispersable latex powder, flyash, cellulose, starch ether, retarder
Gypsum putty powder is hybridly prepared into, compared with traditional powder of lacquer putty for use on performance, it has preferably moistureproof moisture-proof characteristic, and it has certainly
Processability, there are preferably resistance to compression and rupture strength, surface strength is higher, batch scrapes thickness and is not limited, is not susceptible to be cracked
Phenomenon；Traditional putty is solved due to producing intensity with liquid colloid drying and forming-film, it itself can not be molded, no anti-folding and anti-pressing
Intensity, surface strength is relatively low, batch scrapes thickness no more than 0.5mm, and otherwise liquid colloidal is unable to drying and forming-film, produces lacking for cracking
Fall into.
The quality of the wall plastering gypsum compositions of the invention is more excellent, and cost is relatively low；Painted for indoor wall, often
Square metre consumption is 1kg or so.
The raw material that the invention uses is as shown in table 1 below：
Table 1
