Description
Technical field
The present invention relates to a kind of plastering material, is related to a kind of water proof type brushing gypsum and preparation method thereof, belongs to chemical industry and build
Material technical field.
Background technology
Gypsum is as one of traditional three big inorganic coagulation materials, and application field is extensive, at present, as green, environment protection architecture
Material is increasingly burning hot on walling is painted, but because brushing gypsum raw gypsum powder itself has water imbibition, and met in dry mash
A large amount of spaces can be formed during water hydratable and provide chance for moisture invasion and attack, brushing gypsum water suction can excessively cause its mouldy de-
Fall, therefore limit brushing gypsum application, it is difficult to be applied again under southern wet environment, water proof type brushing gypsum meets the tendency of
And give birth to.Patent publication No. CN105130359A reduces the water consumption of slurry using addition flyash, increase system mobility,
The compaction rate of raising system, but it influences brushing gypsum outward appearance, using organosilicon moisture repellent as waterproofing agent, reduces gypsum
Intensity and adhesion.Patent publication No. 102745969A improves brushing gypsum water resistance using liquid silane, waterproof effect compared with
It is good, but gypsum wall caking property is poor by force, gypsum intensity decreases, easily comes off.
The content of the invention
It is an object of the invention to provide a kind of water proof type brushing gypsum and preparation method thereof, solves current rendering stone
Cream poor water resistance is made moist easy mouldy the problems such as coming off.
Technical scheme is used by the present invention solves above-mentioned technical problem：A kind of water proof type brushing gypsum, it includes
Following components and content：50-60 parts desulfurated plaster, 5-20 parts quartz sand, 1-3 parts natural stone-powder, 0.3-0.4 parts retarder,
0.2-0.5 parts cellulose ether, 0.1-0.2 part dispersibilitys latex powder, 0.05-0.3 part water-proof adhesives, in parts by weight.
By such scheme, the particle diameter of described water proof type brushing gypsum is less than 0.074mm.
By such scheme, the retarder is from one kind in sodium tripolyphosphate, citric acid or sodium citrate.
By such scheme, the cellulose ether selects methylcellulose or hydroxypropyl methyl cellulose.
By such scheme, its modulus of fineness of the quartz sand is 1.6-2.2.
By such scheme, the water-proof adhesive is that natural resin glue, polyvinyl alcohol and starch ether are (5-20) in proportion:
(1-5):The mixture of (0.5-2).
The preparation method of the water proof type brushing gypsum, it is characterised in that include following steps：
(1) by 1-3 parts natural stone-powder, 0.2-0.5 parts cellulose ether, 0.1-0.2 part dispersibilitys latex powder, 0.3-0.4
The well mixed obtained gypsum flour additive agent of part retarder, 0.05-0.3 parts water-proof adhesive；
(2) by 50-60 parts desulfurated plaster at 250-300 DEG C calcining at constant temperature 2-3h；
(3) gypsum flour additive agent obtained by the desulfurated plaster, 5-20 parts quartz sand and step (1) after step (2) is calcined is pressed
Ratio, which mixes, is made water proof type brushing gypsum.
By such scheme, the water-proof adhesive is that natural resin glue, polyvinyl alcohol and starch ether are (5-20) in proportion:
(1-5):The mixture of (0.5-2).
The natural stone-powder selected in the present invention can form C-S-H gels in semi-hydrated gypsum hydration process as swelling agent and fill out
Gypsum space is filled, prevents moisture from attacking；The cellulose ether selects methylcellulose or hydroxypropyl methyl cellulose, improves powder
The water retention property of brush gypsum and improve its denseness and anti-vertical fluidity；Using dispersibility latex powder, polyvinyl alcohol and starch ether
Compound action can increase sticky power between gypsum crystal；The natural resin of addition can effectively reduce brushing gypsum
Water absorption rate, improve its water resistance.
The beneficial effects of the present invention are：The cost of the water proof type brushing gypsum of preparation is low, and good water-proof effect, waterproof rate reaches
More than 90%, higher more than the 15Mpa of its more than shear bond strength 0.3Mpa, rupture strength, presetting period and final setting time are short.
