Abstract
The present invention relates to a kind of for caulking agent of plasterboard seam and preparation method thereof, belong to construction material and fabricating technology field.It is for the composition and its weight percent of the special caulking agent of plasterboard seam：Desulfurated plaster 60 80%, filler（Inertia）10 30%, filler（Activity）5 10%, latex powder 0.1 0.3%, water-retaining agent 0.2 0.4%, anti-sag agent 0.01 0.1%, retarder 0.05 0.3%.Special caulking agent for plasterboard seam prepared by the present invention, using industrial solid castoff desulfurated plaster as primary raw material, not only have the characteristics that cohesive force is strong and the compatibility of plasterboard is good, easy painting is scraped, quick solidifying, do not shunk, and the new way of solid waste desulfurated plaster recycling is opened, there is preferable Social benefit and economic benefit.
Description
Technical field
The present invention relates to a kind of for caulking agent of plasterboard seam and preparation method thereof.
Background technology
Desulfurated plaster is after coal-burning power plant administers the sulfur dioxide in flue gas using wet type lime/lime stone-gypsum
Obtained industry by-product gypsum, it has also become the second largest solid waste of power plants.It is coal-fired with the development of power industry
The desulfurated plaster discharge capacity of power plant will increase year by year.At present, it is most of in addition to part is for cement retarder and building materials of gypsum etc.
Still still by air storage, this not only occupies a large amount of valuable land resources, but also returns surrounding enviroment and cause seriously
Pollution.How this large amount of desulfurated plaster high added value and effectively utilizes, and be pendulum utilizes and Building wood in solid waste
Expect the subject in face of field technology personnel.
Plasterboard has light-weight, non-ignitable fire prevention, acoustical and thermal, a dimensionally stable, surfacing, can with sawing, convenient for applying
The features such as work, is widely used in industry and furred ceiling, partition wall, the interior wall veneer in civil buildings etc..Plasterboard construct splice when,
There are about the seams of 5mm for meeting between plate and plate.Traditional caulking material is mainly the material of cement base, generally existing cohesive force is poor,
Easy to fall off, the problems such as shrinking percentage is big, easy to crack, so as to influence the quality of whole building and beauty.Prepared by the present invention is used for
The special caulking agent of plasterboard seam, using industrial solid castoff --- desulfurated plaster is primary raw material, not only with cohesive force
By force with the compatibility of plasterboard is good, easy painting is scraped, quick solidifying, do not shrink the features such as, and open solid waste --- desulfurization
The new way that gypsum resource utilizes.
