Abstract
The invention discloses a kind of anti-freeze type concrete pump-feed agents, are composed of the following raw materials by weight, and 10-20 parts of triethanolamine；5-10 parts of phase transformation lotion；5-15 parts of polycarboxylate water-reducer；5-6 parts of carboxymethyl cellulose；2-5 parts of 2- hydroxyethylmethacry,ate；3-5 parts of maleic anhydride；5-10 parts of ammonium chloride；0.1-0.15 parts of artificial schellite；0.1-0.15 parts of Zinc Tungstate；5-15 parts of sodium citrate；12-30 parts of water；Wherein, the preparation method of the phase transformation lotion is as follows：10-12 parts by weight hydroxy silicon oil, n-decane sodium sulfonate 2-5 parts by weight and 20-30 parts of water are sufficiently mixed, are placed in cutter, while shear agitation, are slowly added dropwise into 2-5 parts of hard fatty acids and 1-2 parts of palm oils.Anti-freeze type concrete pump-feed agent of the invention while having good water reducing ability, has preferable freeze-proof.
Description
Technical field
The present invention relates to a kind of anti-freeze type concrete pump-feed agents and preparation method thereof, belong to building material manufacture field.
Background technique
Concrete is building materials important in construction industry, and pumping admixture, which refers to, can improve the additional of concrete mix pump-conveying property
Agent, so-called pump-conveying property, be exactly concrete mix have can pass through conveyance conduit, do not block, do not isolate, visco-plasticity it is good
Good performance.
With the development of concrete technology, the requirement to concrete admixture is also continuously improved, multi-functional, compound coagulation
Native additive becomes one of developing direction, and the past, pumping admixture and antifreezing agent were all to add to make respectively within a very long time
, and antifreezing agent and " double-doped " use of pumping admixture, other than causing inconvenience to construction, often bring quality to ask to engineering
Topic, for example, will all seriously affect the intensity of concrete mixed with the timesharing of bleed group in pumping admixture and antifreezing agent.It applies for convenience
Work improves the quality of concrete, more and more composite additives used while having pumping and antifreeze function.Deicing pump
Sending agent to become one kind can make pump concrete not generate freeze injury, and can go on smoothly under the conditions of subzero temperature that pour must can not
Few additive.
Summary of the invention
Goal of the invention：The purpose of the present invention is to solve the above the deficiencies in the prior art, provide a kind of anti-freeze type coagulation
Native pumping admixture can improve the impervious, freeze proof of concrete, durability, can reduce concrete slump loss, and water reducing ability is good, fit
Transport and pumping construction together in long range, it is applied widely.
Technical solution：A kind of anti-freeze type concrete pump-feed agent of the present invention, is composed of the following raw materials by weight,
The preparation method of the phase transformation lotion is as follows：By 10-12 parts by weight hydroxy silicon oil, n-decane sodium sulfonate 2-5 weight
It measures part and 20-30 parts of water is sufficiently mixed, be placed in cutter, reporting is 8000-1000 revs/min, and shear time is 15-30 points
The palm oil of the hard fatty acids and 1-2 part into 2-5 parts is slowly added dropwise to get phase transformation lotion in clock.
A kind of anti-freeze type concrete pump-feed agent, further has preferably, is composed of the following raw materials by weight,
Beneficial effect：
1) anti-freeze type concrete pump-feed agent of the invention has preferable impervious, durability, can reduce Control Measures for Concrete Slump
Degree loss while water reducing ability is good, has preferable freeze-proof.
2) present invention discharges phase transformation using phase-change energy-storage temperature adjustment mechanism by the addition of phase transformation lotion in temperature-fall period
The characteristic that latent heat of phase change is stored in latent heat, temperature-rise period, inherently changes concrete pump-feed agent to the adaptability of temperature.

Divide mixing, be placed in cutter, reporting is 8000-1000 revs/min, and shear time is 15-30 minutes, is slowly added dropwise into 5 parts
Hard fatty acids and 2 parts of palm oil to get phase transformation lotion.
Embodiment 2
A kind of anti-freeze type concrete pump-feed agent, is composed of the following raw materials by weight described in the present embodiment,
The preparation method of the phase transformation lotion is as follows：12kg hydroxy silicon oil, n-decane sodium sulfonate 2kg and water 30kg are filled
Divide mixing, be placed in cutter, reporting is 8000-1000 revs/min, and shear time is 15-30 minutes, is slowly added dropwise into 5 parts
Hard fatty acids and 2 parts of palm oil to get phase transformation lotion.
The performance indicator of the present embodiment 1,2 gained anti-freeze type concrete pump-feed agents, as shown in table 1.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
