Cross the insulation material that after mix machine can be used to spray.
In recent years, comprehensively utilize industrial residue and prepare new green energy saving construction material as the one of China's building material industry
Individual important development trend, novel gypsum base Warming machine sandblasting is prepared using industrial solid castoffs such as desulfurated plaster, slag micropowders
Starch and a popular research is turned into using machine spray spraying technology construction technology production cold bending thin wall type light-weight structure residence industry
Problem.
The content of the invention
Present invention aim to address above-mentioned deficiency, there is provided a kind of light weight, thermal and insulating performance are good, cost is low, construction
Speed is fast, the desulfurized gypsum base machine of machine spraying can be used to spray thermal insulation mortar, and it is a further object of the present invention to provide above-mentioned material
The preparation method of material.
To achieve the above object, the invention provides a kind of desulfurized gypsum base machine to spray thermal insulation mortar, its each component and each group
The parts by weight difference divided is as follows：Calcine desulfurization gypsum powder 65-85 parts, cement 5-10 parts, slag micropowder 10-20 parts, thixotroping lubrication
Agent 0-2.5 parts, EPS particle 0.8-2.2 parts, redispersable latex powder 0.4-1 parts, water-loss reducer 0.2-0.8 parts, alphalise starch 0.2-
0.8 part, calcium sulphate retarder 0.05-0.35 parts, polyvinyl alcohol 0.1-0.5 parts, water 50-80 parts.
The specific surface area of wherein preferably described calcining desulfurization gypsum powder is 250-400m2/ kg, its main component are half water
Gypsum；The specific surface area of the slag micropowder is 325-500m2/kg；The cement is the cement of PO 42.5.
It is preferred that described redispersable latex powder is VAE latex powder, vinyl acetate-versatic acid
One kind in vinyl acetate-acrylic ester copolymer latex powder or polyvinyl acetate-generating vinyl carboxylate-ethylene copolymer.
It is preferred that described calcium sulphate retarder is one kind in sodium citrate, citric acid, sodium polyphosphate or tartaric acid；It is described
Water-loss reducer be hydroxypropyl methyl cellulose ether (HPMC) or methyl cellulose ether (MC), viscosity is between the mpas of 5-20 ten thousand；
Described alphalise starch can be swelled into translucent liquid in water；Described thixotropic lubricant is in aluminium-magnesium silicate or bentonite
It is a kind of；Described polyvinyl alcohol is the product of molecular weight 100,000.
It is preferred that the particle diameter of described EPS particles is between 0.30-0.5mm, bulk density 4.5-5.5kg/m3。
Present invention also offers a kind of above-mentioned preparation method of desulfurized gypsum base machine spray thermal insulation mortar, its specific steps is such as
Under：First will calcining desulfurization gypsum powder, cement, slag micropowder, thixotropic lubricant, calcium sulphate retarder, water-loss reducer, alphalise starch, poly- second
Enol, redispersable latex powder are put into multi-functional dry powder blender, are mixed 5-15 minutes, are obtained well mixed guarantor
Warm mortar masterbatch, masterbatch is put into mortar mixer during use, mixed after adding water, 60-80 revs/min of mixer rotating speed,
2-5 minutes are stirred, then put into EPS particles, 60-80 revs/min of mixer rotating speed, 5-10 minutes is stirred, obtains gypsum base rubber powder EPS
Particle heat-insulating Machine-blasting mortar.
A kind of desulfurized gypsum base machine sprays thermal insulation mortar as a kind of heat-insulating material in the present invention, light in cold bending thin wall type
Packing material is used as in steel construction, the heat transfer coefficient of masonry wall structure is reduced, reduces heat conduction efficiency, it is effective to prevent
The transmission of winter indoor heat from-inner-to-outer at night, has reached the purpose of insulation.Because desulfurated plaster main component is
Semi-hydrated gypsum, its heat evolution velocity is very rapid, is often unfavorable for the use in architectural engineering；After the calcining that the present invention utilizes
Desulfurated plaster passes through the slow setting of calcium sulphate retarder, adds the operating time of spray coating heat preservation mortar；Water-loss reducer is added into add
The water-retaining property of mortar and the internal cohesion of mortar；While alphalise starch adds consistency of mortar, reduce water-loss reducer hydroxypropyl first
The usage amount of level cellulose or methyl cellulose ether (MC), has saved cost；The introducing of polyvinyl alcohol adds machine spray insulation sand
The flexibility of slurry, reduces the dosage of redispersable latex powder, while enhances the bonding force with light steel, structural slab；Cement, slag
The intensity after mortar hydration and hardening and water resistance is further increased in the incorporation of micro mist；And EPS particles make mortar quality more
Gently, thermal and insulating performance is more preferable, effectively reduces the heat transfer coefficient of masonry wall structure, improves thermal insulation mortar thermal insulation；Together
When other multiple elements design additives incorporation make it machine can be used to spray, and not plugging in spraying, not sagging, no after spraying
It is sliding.
Using above-mentioned technical proposal, the present invention has the advantages that：
Desulfurated plaster of the present invention is mainly the industrial by-product from thermal power plant, steel mill or large chemical complex
Thing, semi-hydrated gypsum is obtained after calcining, use in building material industry instead of the natural gypsum, can both economize on resources, again can be with
Industry byproduct solid pollution is prevented, is preserved the ecological environment, environmental protection and energy saving；Gypsum base machine spray thermal insulation mortar tool of the present invention
There is preparation method simple, cost is cheap, has good thermal and insulating performance；Desulfurized gypsum base machine spray insulation of the present invention
Mortar can machine spraying, while speed of application is fast, more save manual labor amount, saved cost；It is of the present invention de-
Sulphur gypsum base machine spray thermal insulation mortar machine spraying in not plugging, after spraying not sagging, do not slide.
