Description
Technical field
The present invention relates to building mortar technical field, in particular to a kind of phase-changing wall slurry and preparation method thereof.
Background technique
Important component of the wall as architectural exterior-protecting construction, is mainly poured by phase-changing wall slurry.Wall section
Energy technology plays an important role in building energy conservation, and the research and development of body of wall energy-saving material and construction receive significant attention.So
And the power save mode of current architectural exterior-protecting construction mainly adds insulating layer in wall, although insulating layer reduces wall and goes along with sb. to guard him knot
The heat transfer coefficient of structure, but it plays the role of limited in terms of accumulation of energy, cannot improve indoor air quality, can not improve room
The comfort level of interior environment.
Summary of the invention
The main object of the present invention is to provide a kind of phase-changing wall slurry, it is intended to improve indoor air quality, improve room
The comfort level of interior environment.
To achieve the above object, phase-changing wall slurry proposed by the present invention, in terms of mass fraction, including 10~20 parts of swellings
Soil, 30~45 parts of portland cements, 5~10 parts of calcium sulfate crystal whiskers, 0.5~1.3 part of polycarboxylate water-reducer, sand in 25~30 parts,
35~45 parts of stones, 60~80 parts of Phase-change ceramic grains, 13~25 parts of negative ion powders and 30~50 parts of water.
Optionally, the Phase-change ceramic grain includes phase transformation group material and encapsulating material, the matter of the phase transformation group material and encapsulating material
Amount is than being (2~3): 1.
Optionally, the phase transformation group material includes phase transition agent and porous ceramic grain, the matter of the phase transition agent and the porous ceramic grain
Amount is than being (3~4): 1.
Optionally, the phase transition agent includes sal glauberi, paraffin and calcium chloride hexahydrate, the calcium chloride hexahydrate, described
The mass ratio of paraffin and the sal glauberi is 5:4:2.
Optionally, the preparation method of the phase transition agent includes: the mixture to sal glauberi, calcium chloride hexahydrate and paraffin
Middle addition water and heating water bath dissolution, wherein the mass ratio of mixture and water is 3:1, and phase transition agent is prepared.
Optionally, the preparation method of the phase transformation group material includes: under vacuum conditions, phase transition agent to be imported into porous ceramic grain
In, so that phase transition agent is adsorbed in the hole of porous ceramic grain, phase transformation group material is prepared.
Optionally, the encapsulating material includes cement paste and styrene-acrylic emulsion, the cement paste and the styrene-acrylic emulsion
Mass ratio be (1.1~1.3): 1.
Optionally, the preparation process of the Phase-change ceramic grain includes: that phase transformation group material is added in styrene-acrylic emulsion, so that phenylpropyl alcohol
Lotion is coated on the phase transformation group material surface, and after the solidification of the styrene-acrylic emulsion on the phase transformation group material surface, cement paste is added simultaneously
Mixing, is prepared Phase-change ceramic grain.
Optionally, the negative ion powder includes tourmaline and ceria, the matter of the tourmaline and the ceria
Amount is than being (2~5): 0.1.
The present invention also proposes a kind of preparation method of phase-changing wall slurry, comprising the following steps: by bentonite, silicate cement
Mud, calcium sulfate crystal whiskers, polycarboxylate water-reducer, middle sand, stone and water mixing, are prepared into cement mortar；Successively to the cement bonded sand
Phase-change ceramic grain and negative ion powder are added in slurry, phase-changing wall slurry is prepared.
In technical solution of the present invention, phase-changing wall slurry include 10~20 parts of bentonites, 30~45 parts of portland cements,
5~10 parts of calcium sulfate crystal whiskers, 0.5~1.3 part of polycarboxylate water-reducer, sand, 35~45 parts of stones, 60~80 parts of phases in 25~30 parts
