Description
Technical field
The present invention relates to a kind of mortar, particularly relating to a kind of dedicated mortar for making aerated bricks.
Background technology
Aerated bricks is the aerated bricks building block of being produced by autoclave at high temperature apparatus and process, and namely adopt the brick product comprising other various explained hereafter of steam pressure, its unique distinction is that it is a kind of novel building walling of very light-duty heat insulating.Aerated bricks sharpest edges economize the land resource exactly, need not waste a large amount of arable lands, and its raw material is drawn materials extensively, dust and sand, slag, and flyash and coal gangue etc. are all the starting material doing aerated bricks, after raw material is mixed into mortar, then make aerated bricks through moulding process.Slurry composition prepared by current most manufacturer and performance perfect not, cause the aerated bricks made to occur low, the easy explosion of intensity, water-fast weak, the defect such as heat resistance is poor, its technical recipe still needs further improvement.
Summary of the invention
In order to solve the problem, the invention provides a kind of dedicated mortar for making aerated bricks, make products made thereby have good over-all properties by rational component proportion.
The present invention is achieved through the following technical solutions:
For making a dedicated mortar for aerated bricks, be made up of the material of following weight part:
30 ~ 35 parts of cement, 30 ~ 40 parts of quartz sands, 10 ~ 15 parts of flyash, 4 ~ 6 portions of treated starches, 3 ~ 5 parts of hollow glass micropearls, 0.2 ~ 0.5 part of redispersible latex powder, 1 ~ 3 part of Sodium Benzoate, 2 ~ 4 parts of auxiliary agents.
Further, described quartz sand SiO
2content more than 98%, and through following steps process:
(1) massfraction quartz sand being placed in its quality 3 ~ 5 times is that after the hydrochloric acid immersion 30 ~ 40min of 20 ~ 25%, taking-up is extremely neutral with deionized water rinsing;
(2), after calcining 2 ~ 3h under the quartz sand after washing being placed in the condition of 650 ~ 800 DEG C, take out and be cooled to room temperature;
(3) by calcining after quartz sand pulverize and sieve after be made into can 100% cross 60 orders, more than 60% can cross 100 object sand grains.
Further, described cement is Portland blast furnace slag cement.
Further, described treated starch is raw material with W-Gum, using Trisodium trimetaphosphate as linking agent, under the katalysis of sodium hydroxide, carries out cross-linking modified a kind of cross-linking starch to W-Gum.
Further, the particle diameter of described hollow glass micropearl is 150 ~ 200 μm.
Further, described redispersible latex powder selects model to be SWF-05.
Further, described auxiliary agent is made up of the material of following weight part: 3 ~ 5 parts of ethoxylated alkyl sodium sulphite, 2 ~ 4 parts of polysiloxane, 5 ~ 7 parts of trolamines, 1 ~ 3 part of Zinic stearas, 3 ~ 5 parts of casein food grade form.
The present invention has following beneficial effect:
(1) after quartz sand being carried out pre-treatment, improve its surface properties and the physical property such as intensity, resistivity against fire, and then improve the physicochemical property such as intensity, resistivity against fire of mortar and goods thereof.
(2) the cross-linking modified starch added has unique hyperspace reticulated structure, has stronger bounding force, and then improves the intensity of mortar and goods thereof, anti-shear performance and freeze-thaw stability.
(3) hollow glass micropearl is a kind of inorganic non-metallic filler of excellent property, profile is spherical shape, inside is thin gas, make the goods of this mortar have good weight capacity, sound-proofing properties and water resistance, and jointly improve its intensity and fire performance with pretreated quartz sand.
(4) to sum up, the present invention is by reasonable component collocation and process, mortar and goods thereof are made to have good insulation, noise reduction, fire-resistant, corrosion-resistant property, there is again higher resistance to compression, the mechanical property such as anti-shearing simultaneously, overall characteristic comparatively market like product improves a lot, there is stronger competitive power, be worthy to be popularized.
Embodiment
Embodiment 1
For making a dedicated mortar for aerated bricks, be made up of the material of following weight part:
33 parts of cement, 40 parts of quartz sands, 10 parts of flyash, 4 portions of treated starches, 3 parts of hollow glass micropearls, 0.3 part of redispersible latex powder, 2 parts of Sodium Benzoates, 4 parts of auxiliary agents.
Further, described quartz sand SiO
2content more than 98%, and through following steps process:
(1) massfraction quartz sand being placed in its quality 3 times be 25% hydrochloric acid soak 30min after, taking-up with deionized water rinsing to neutral;
(2), after calcining 3h under the quartz sand after washing being placed in the condition of 650 ~ 750 DEG C, take out and be cooled to room temperature;
(3) by calcining after quartz sand pulverize and sieve after be made into can 100% cross 60 orders, more than 60% can cross 100 object sand grains.
Further, described cement is Portland blast furnace slag cement.
Further, described treated starch is raw material with W-Gum, using Trisodium trimetaphosphate as linking agent, under the katalysis of sodium hydroxide, carries out cross-linking modified a kind of cross-linking starch to W-Gum.
Further, the particle diameter of described hollow glass micropearl is 150 ~ 200 μm.
Further, described redispersible latex powder selects model to be SWF-05.
Further, described auxiliary agent is made up of the material of following weight part: 3 parts of ethoxylated alkyl sodium sulphite, 2 parts of polysiloxane, 5 parts of trolamines, 3 parts of Zinic stearass, 3 parts of casein food grade form.
The model that 150mm × 150mm × 50mm made in the same way by made for embodiment 1 mortar and ordinary mortar is carried out performance test, and its result is as shown in the table:
