Description
Technical field
The invention belongs to building material technical field, what be specifically related to a kind of wall insulation system special use is the finish coat mortar of base-material with the desulfurated plaster.
Background technology
Wall thermal insulating is heat insulation to be the important step of construction industry energy-saving and emission-reduction.At present, China relevant department requires the new building thing to realize energy-conservation 50% target, and key cities such as Shanghai, Beijing, Tianjin then must reach 65% energy-saving effect.Wall insulation system is divided into insulation and four kinds of patterns of exterior wall self-heat conserving in external wall outer insulation, exterior wall internal insulation, the exterior wall.Wherein, external wall outer insulation does not influence interior decoration, does not take the house usable floor area, buildings is had provide protection, can eliminate advantages such as cold and hot bridge and overall economic efficiency be obvious with it, becomes a kind of building energy conservation pattern that current China generally adopts.External thermal insulation system comprises that mainly expansion polyphenyl plate approaches plastoring system, the polyurethane series thermal insulation mortar system that unifies.The thermal insulation mortar system construction is convenient, and good integrity is subjected to engineering circle and generally praises highly.The thermal insulation mortar of having produced already comprises the expansion polyphenyl granule heat-insulating mortar and two kinds of pearlstone (glass bead) thermal insulation mortars of remaining silent.No matter adopt which kind of thermal insulation mortar, still need in the system supporting boundary mortar and finish coat mortar, and compound enhancing net sheet.
It is base-material that finish coat mortar in the thermal insulation mortar outer heat preservation system adopts usually with cement, is aided with mineral admixture, size fractionated quartz sand and the formulated product of various additive.Work of the present invention then aims at the resource utilization application problem of a large amount of desulfurated plasters that produce when preceding running because of the power plant desulfurization device, and having developed successfully a kind of of wall insulation system special use is the finish coat mortar of base-material with the desulfurated plaster.
Summary of the invention
What the object of the present invention is to provide a kind of wall insulation system special use is the finish coat mortar of base-material with the desulfurated plaster, this finish coat mortar is base-material with the desulfurated plaster, be aided with other industrial solid castoff and calcium lime powder and form composite gelled material, with calcium chloride as chemical activator, with quartz sand for gathering materials, with calcium-base bentonite and Mierocrystalline cellulose-acrylate graft copolymers is water-holding agent, is the special-purpose finish coat mortar of heat-insulation system that stress disperses anti-fissuring agent with the cellulosic fibre.Finish coat mortar of the present invention can use after directly adding the water stirring at the construction field (site), and product sclerosis back ultimate compression strength is moderate, and with thermal insulation mortar cohesive strength height, good toughness, water-tolerant, shrinking percentage is little.
A kind of wall insulation system special use that the present invention proposes be the finish coat mortar of base-material with the desulfurated plaster, this finish coat mortar is made up of desulfurated plaster, flyash, metakaolin, calcining coal gangue, calcium lime powder, calcium chloride, 50-80 order quartz sand, 100-120 order quartz sand, calcium-base bentonite, Mierocrystalline cellulose-acrylate graft copolymers and cellulosic fibre.The weight ratio of its component is as follows:

Among the present invention, its SO of described desulfurated plaster
3Weight content more than or equal to 42% less than 60%.
Among the present invention, described flyash is a kind of in I level F class flyash or the II level F class flyash.
Among the present invention, described metakaolin be natural kaolin 600-1000 ℃ of calcining more than 1.5 hours and levigate to specific surface area greater than 350m
2The powder of/Kg.
Among the present invention, described calcining coal gangue be the raw coal spoil 600-950 ℃ of calcining more than 2.0 hours and levigate to specific surface area greater than 380m
2The powder of/Kg.
Among the present invention, the length of described cellulosic fibre less than 9mm greater than 0mm.
The preparation method of the finish coat mortar that the present invention proposes, its concrete steps are as follows:
(1) take by weighing raw material by weight, and with 50-80 order quartz sand, 100-120 order quartz sand, cellulosic fibre dry mixing in advance is to uniform state;
(2) desulfurated plaster, flyash, metakaolin, calcining coal gangue, calcium lime powder, calcium chloride, calcium-base bentonite and Mierocrystalline cellulose-acrylate graft copolymers are added in the mixture in the step (1);
(3) be mixed to uniform state;
More than each step all under normal temperature and normal pressure, carry out.
The finish coat mortar using method of gained of the present invention is: adds and can take after the water uniform mixing streak method to carry out the finish coat construction, and can compound alkali resistant glass fibre open weave cloth and Galvanized Steel Wire Netting, dry sclerosis back forms the integral body with certain impelling strength.
Among the present invention, desulfurated plaster, flyash, metakaolin, calcining coal gangue, calcium lime powder are formed the cementitious material system of polycomponent non-cement grog jointly.Flyash, metakaolin and calcining coal gangue all contain aluminium sesquioxide and the ferric oxide that has lateral reactivity in a large number, under the alkali environment that the calcium hydroxide that they generate at calcium lime powder chance water hydratable provides, combine with the sulfate ion of desulfurated plaster stripping, form the extremely low ettringite (3CaO.Al of solubleness
2O
