The invention discloses a kind of extremely cold type cement glue, include the raw material of following parts by weight：2 parts of cement, 0.8~1.1 part of quartz sand, 0.45~0.52 part of water, 0.05~0.07 part of water reducer, 0.25~0.30 part of silicon ash, 0.001~0.002 part of air entraining agent.The extremely cold more universal cement glue Freeze-thawing Tolerance of type cement glue of the present invention can significantly improve, reduce the internal stress effect between steel pin, cement glue, porcelain piece, chapeau de fer as caused by cement low-temperature expansion, so as to reduce the possibility of porcelain piece destruction, probability of malfunction of the porcelain insulator under steep wave impact is fundamentally reduced.
Description
Technical field：
The present invention relates to a kind of extremely cold type cement glue, belong to a kind of porcelain insulator production materials.
Background technology：
With the development of power industry, super-pressure, large span, long distance power transmission have obtained rapid popularization.To meet electric power
The development of industry, extra-high voltage electric transmission and transformation technology propose higher requirement to insulator, each element are required higher
Reliability.
Cement glue be by cement, gather materials, water is allocated form by a certain percentage, mistake of the cement glue in hydration and hardening
Intensity gradually increases in journey.Cement glue is the important component of electromagnetic product, plays and forms porcelain piece and metal-ware
Overall effect, its quality is directly connected to the performance of insulator, life and reliability, at present in electromagnetic product, cement gel
Mixture is most weak link, hence it is evident that can not meet production requirement, especially in use, its is resistance under the extremely cold environment of northern area
Freeze thawing performance is difficult to satisfaction and required, cement glue is interior between low-temperature expansion, steel pin, cement glue, porcelain piece and chapeau de fer
Stress is big, and porcelain insulator easily destroys under steep wave impact, breaks down.
The content of the invention：
To solve the above problems, it is an object of the invention to provide a kind of freeze-thaw resistance property it is high, suitable under extremely cold environment
The cement glue used.
The purpose of the present invention is implemented by following technical scheme, and a kind of extremely cold type cement glue, it includes following parts by weight
Raw material：
2 parts of cement,
0.8~1.1 part of quartz sand,
0.45~0.52 part of water,
0.05~0.07 part of water reducer,
0.25~0.30 part of silicon ash,
0.001~0.002 part of air entraining agent.
Further, it includes the raw material of following parts by weight：
2 parts of cement,
1 part of quartz sand,
0.49 part of water,
0.06 part of water reducer,
0.28 part of silicon ash,
0.0014 part of air entraining agent.
Further, the air entraining agent is the one or more in colophonium pyrolytic polymer, rosin soap, sodium alkyl benzene sulfonate.
Air entraining agent is also known as air-entrainment, usually the surfactant of water.Formed when being dissolved in stirring after water in mortar a large amount of
Micro air bubble, about 50~125 μm of size, because surface-active substance mass-energy orients and adsorbs on the surface of bubble, therefore it can make
Bubble is not easily broken.Equally distributed micro-bubble reduces the contact between sand grains, can improve the mobility and stably of mud
Property (anti-bleeding capacity).Micro air bubble in hardened paste has completely cut off the passage of capillary, prevents water translocation, adds deformation
Ability.Air entraining agent is to improve one of effective measures of freezing tolerance under cement glue low temperature.
Further, the cement is the portland cement that label is more than 52.5.
Further, the water reducer is polycarboxylic-acid ADVA high efficiency water reducing agents.
ADVA high efficiency water reducing agents have that volume is low (0.4%-1.2%), water-reducing rate height (25%-40%) and large dosage cement
Mixed again with sand, cement glue Workable.The extremely cold type cement glue prepared has Cl-Diffusion coefficient is small, and shrinkage value is low,
Commerical ready-mixed concrete aquation temperature rise is gentle, meets extremely cold area requirement.
Using ADVA high efficiency water reducing agents, in the case where ensureing cement glue workability, water consumption, the ratio of mud are reduced,
Improve intensity.From the cement-sand ratio under suitable low temperature, the heat of hydration is reduced, increases the compactness and stability of adhesive structure, subtracts
Few volume contraction, reduces interior porosity, improves durability.
Further, the granularity of the quartz sand is 30-100 mesh.
Advantages of the present invention：The extremely cold more universal cement glue Freeze-thawing Tolerance of type cement glue of the present invention can be obvious
Improve, the internal stress effect between steel pin, cement glue, porcelain piece, chapeau de fer as caused by cement low-temperature expansion is reduced, so as to drop
The possibility that low porcelain piece is destroyed, fundamentally reduce probability of malfunction of the porcelain insulator under steep wave impact.
