Description
Technical field
The present invention relates to construction material processing technique fields, and in particular to a kind of processing side of fire-type light gypsum mortar
Method.
Background technique
Mortar can be divided into ordinary mortar and extraordinary mortar from performance and purposes, and the raw material that wherein ordinary mortar uses is general
Water flowing mud, sand, mortar additive etc., raw material proportioning is fairly simple, and ordinary mortar performance indicator is difficult to meet construction of special positions
It is required that therefore, the extraordinary mortar of Various Functions has corresponding physical property and chemical property for different purposes, compensate for general
Disadvantage of the logical mortar in assembled architecture construction.With the development of scientific progress, extraordinary mortar include polymer bonding mortar,
Thermal insulation mortar, decoration mortar, gravity flowing levelling mortar and waterproof mortar etc., extraordinary mortar quality, efficiency, in terms of all have
Unique feature.
In terms of fire-proof heat-insulating, existing gypsum mortar selects common lime mortar mostly, and fire protecting performance is poor, thermally conductive
Coefficient is larger, and when a fire, quick conductive quickly increases wall temperature, and then increases fire behavior.
Summary of the invention
To solve the above-mentioned problems, the present invention provides a kind of processing method of fire-type light gypsum mortar, the present invention
Design concept are as follows: assign light gypsum mortar have fireproof performance, the thermally conductive of finished light gypsum mortar is greatly lowered
Coefficient increases House fires and difficulty occurs, and then when House fires occur, can effectively slow down the development of the intensity of a fire, for people within doors
Member provides more effective escape times of fire.
The present invention is achieved by the following technical solutions:
A kind of processing method of fire-type light gypsum mortar, including fire proofing material, modified yellow soil, aggregate original washing powder press 6
The weight ratio hybrid process of~8:1:10~12 is made；

1~2h is stirred under the speed of 1500r/min, is then allowed to stand 24~48h of precipitating, upper layer suspension is filtered, distills water washing, such as
This 3~4 times repeatedly, yellow soil is added in the sulfuric acid solution that volume fraction is 15% according to solid-to-liquid ratio 1:20~25 after drying,
3~6h is stirred under 80~90 DEG C of bath temperature, is filtered, and washing is until pH value is neutral；Then according to solid-to-liquid ratio 1:15~
20 are added to yellow soil in the sodium chloride solution that mass fraction is 10%, 60~70 DEG C of bath temperatures and 2000~
5~8h, 20~40min of ultrasonic disperse under the power of 300~400W are stirred under the revolving speed of 3000r/min, is filtered, and washing is extremely
Cleaning solution is without Cl-Until；Yellow soil is finally placed in 2~4h of calcining at 580~640 DEG C, is cooled to room temperature, crushed 300 mesh
Sieve is to get activation yellow soil；
By weight, active yellow soil, SiO 2 powder, titania powder, ardealite powder are weighed, is puddled
The distilled water of 20~30 times of quality is pumped into after even, 2~3h of magnetic agitation stands 1~1.5h after being uniformly dispersed, yellow soil cream is made
Liquid；It is slowly added to the calcium chloride water that mass fraction is 5% under magnetic agitation, puddles 2~3h, filters, dries, crushes
300 meshes are crossed to get modified yellow soil；
B, prepared by aggregate original washing powder: half water building gypsum plaster, dicalcium powder, floating bead, cellulose powder, latex powder is weighed, in having
It being stirred evenly in the reaction kettle of blender, is heated to 95~105 DEG C, regulation reactor pressure is 0.1~0.15MPa, in 125~
150r/min's stirs under speed the closed 10~15min that puddles to get aggregate original washing powder；
C, prepared by fire proofing material: taking aerosil, is mixed into coalescing agent, retarder, etherification starch, continues to stir
Uniformly, ultrasonic oscillation is uniformly dispersed to get fire proofing material；
D, prepared by mortar: by weight modified yellow soil is pumped into above-mentioned aggregate original washing powder, being dispersed with stirring 1~1.2h；Again
It is pumped into fire proofing material by weight, continues to be dispersed with stirring 3~4h；It is 1.0~1.8 to get finished product that clear water, which is added, and deploys to consistency
Fire-type light gypsum mortar.
Preferably, the modified yellow soil includes:
75~80 parts of active yellow soil, 10~15 parts of SiO 2 powder, 4~7 parts of titania powder, ardealite powder
3~5 parts；
Wherein, each raw material powder particle size≤0.05mm.
Preferably, the additional amount of the calcium chloride water is the 10~15% of the yellow soil lotion.
Preferably, the aggregate original washing powder includes:
Half 500~700 parts of water building gypsum plaster, 100~110 parts of dicalcium powder, 150~180 parts of floating bead, cellulose powder 2~5
Part, 8~12 parts of latex powder.
Preferably, the fire proofing material includes:
20~30 parts of aerosil, 4~7 parts of coalescing agent, 2~4 parts of retarder, 1~2 part of etherification starch；
Wherein, the aerosil partial size is 0.5~2mm.

Further, the retarder includes calcium gluconate, sodium citrate, calcium citrate, peroxophosphoric acid hydrogen calcium, sulfuric acid
It is any one or more than one in zinc, wooden sodium sulfonate.
Preferably, in step c, the ultrasonic oscillation frequency is 25~30KHz, and vibration jitter time is 45~60min.
The beneficial effects of the present invention are:
Compared with prior art, the present invention passes through the preparation of modified yellow soil, and then increases the caking property of yellow soil and interior
Part sub-aperture gap increases its intermolecular pore volume, then puddles allotment with fire proofing material, and cooperation coalescing agent, retarder, film forming help
The application of agent, so that the effective component of fire proofing material is completely wrapped in inside mortar product, especially modified yellow soil point
In sub-aperture gap, after mortar after construction gradually dries out, the fire proofing material can be swollen inside the very big modification yellow soil in gap
It is swollen, the thermal coefficient of light gypsum mortar is reduced, its ignition point is improved, is finally reached fire-proof heat-insulating purpose；
Secondly, removing metal component in soil in the modified yellow soil substantially, reduce the density of yellow soil, and reduce it and lead
Hot coefficient, then with the application with fire proofing material, puddle into aggregate original washing powder, leading for finished light gypsum mortar is greatly reduced
Hot coefficient, so when slowing down fire wall heat transmission, fire behavior is extenuated, when creating more gold for personnel within doors and fleeing for life
Between；
Furthermore it is rich in a large amount of crystallization water in the finished light gypsum mortar, is applied on wall and dries at it
Afterwards, the crystallization water also exists in the same old way, and when fire occurs, clean water can absorb a large amount of heat, and then slow down heat transfer, reach fire prevention
Purpose；
Finally, the finished light gypsum mortar adhesion strength is high, seldom there is hollowing and cracking；After construction in 8 hours
Final set greatly shortens the construction period, and reduces building site overall cost；It is light, reduce wall load.
