Technical field
The present invention relates to the technical fields of concrete stirring and processing, and in particular to a kind of concrete antifreezer and its preparation side
Method.
Background technique
In construction, either ground, pile foundation construction or building construction construction is required to a large amount of concrete.And
During concrete stirring and processing, the stirring and processing of concrete is completed outdoors substantially.When winter stirring and processing,
Since concrete temperature and outside air temperature difference increase, heat exchange can be generated between concrete and ambient temperature, works as ring
When border temperature is very low, this heat exchange will soon reduce the temperature of concrete, for fresh concrete, what temperature reduced
Speed directly determines the size of hydration temperature, and temperature reduction is faster, and the growth of concrete strength is slower.When concrete is premature
After enduring cold, intensity would not increase again, and the free moisture for even remaining in inside concrete is also higher, the frost-heave force after freezing
Bigger, concrete is more more easily damaged.The main reason for concrete strength reduces is that volume increases after water freezes, and frost heave is answered
Power just increases with it and generates crack, so that concrete structure be made to be destroyed.It is in the first few hour of concreting
At the time of risk maximum.
It is mixed to improve the prior art mainly adopts antifreezing agent is added into concrete in order to improve the resistance to frost of concrete
Solidifying soil resists cold freeze-proof.Currently, the antifreezing component of anti-freezing agent for concretes contains nitrite, nitrate, villaumite, urine more
Element, ammonium hydroxide etc..Authorization Notice No. is that the patent of invention of 103496907 B of CN discloses a kind of ultralow temperature frost-resistant concrete, is passed through
Antifreezing agent is added into concrete to make concrete that ultralow temperature antifreezing effect may be implemented, used antifreezing agent is by nitric acid
Salt, calcium formate and water mixing are constituted；Although the antifreezing agent of the patent may be implemented the antifreeze purpose of low temperature, but nitrate or Asia
Nitrate has carcinogenesis, and easily leads to alkali-aggregate reaction in concrete, to cause the bad phenomenons such as the accumulation of salt in the surface soil, influences construction quality
And normal use.In addition, the villaumite in the antifreezing component of anti-freezing agent for concretes influences to build to steel bar corrosion in the prior art
Service life；Urea, ammonium hydroxide etc. discharge penetrating odor, influence environmental quality.
Summary of the invention
In view of the deficienciess of the prior art, the first purpose of this invention is to provide a kind of concrete antifreezer, answer
In concrete stirring and processing, it can make concrete that there is freeze proof, resistance to frost, and product environmental protection, not influence to build matter
Amount and normal use.
The first purpose of this invention is achieved through the following technical solutions:
A kind of concrete antifreezer, the raw material components including following parts by weight: 20-35 parts of acrylic emulsion, hollow glass micropearl
2-7 parts, 0.4-1 parts of Tea Saponin, 25-40 parts of sodium cellulose glycolate, 8-15 parts of alkyl glycosides, Disodium sulfosuccinate 0.1-
The weight of 0.3 part, 30-50 parts of water-reducing agent and 100-180 parts of water, the acrylic emulsion and hollow glass micropearl is 5-
10。
By using above-mentioned technical proposal, acrylic emulsion, milky white (micro- indigo plant) emulsion, solid content 40 ± 1%, nontoxic,
It is non-stimulated, it is harmless, meet environmental requirement, the high photopolymer resin of non-film, with excellent gloss and the transparency, resistance to blocking
Can be good, so as to reduce the adhesive of aggregate, improve the dispersion performance of aggregate.Hollow glass micropearl is small ball
Body, ball-type rate is big, has the smallest specific surface area, it can have good dispersibility in aggregate, it is easy to quilt
It presses closely, therefore it has very high filling capacity；It is shunk containing gas with preferable cold-and-heat resistent in hollow glass micropearl
Property, to enhance the temperature resistance denaturation energy of concrete, reduce concrete causes to crack because being affected by thermal expansion and contraction, so as to mention
The anti-freezing property of high concrete.Tea Saponin also known as tea saponin, be by extracted in tea tree seed (tea seed, tea seeds) one
Class glycoside compounds are a kind of nonionic surface active agent of natural environmental-protective of good performance, in the solution due to Tea Saponin
It is not to exist with ionic condition, so its stability is high, is not influenced vulnerable to existing for strong electrolyte, also not vulnerable to sour, alkali
It influences, has good dissolubility in various solvents, strong adsorption does not occur on a solid surface.By acrylic emulsion with
Hollow glass micropearl is dispersed in hollow glass micropearl in acrylic emulsion, hollow glass with the proportion for merging both control
A large amount of micro-bubbles that glass microballon generates concrete stirring and processing Tea Saponin surround, and are squeezed bubble micro- in each hollow glass
In reticulated void between pearl, when concrete makes a reservation for low using temperature ratio, the water in concrete freezes and is pressed into gas
In bubble, the influence to concrete structure is greatly lowered, to further increase the anti-freezing property of concrete.Acrylic emulsion can
Improve aggregate between adhesive property, keep structure more closely knit and with concrete mortar interpenetrating matrix, be packed in aggregate hollow
