Abstract
The invention relates to a composite concrete antifreeze and a preparation method thereof. The composite concrete antifreeze mainly comprises polyethylene glycol methacrylate, rosin or sodium alkyl benzene sulfonate, hexametaphosphate, polyhydroxy acid sodium gluconate and a proper amount of water. The composite concrete antifreeze can greatly increase the temperature of the concrete at the critical strength to prevent the concrete from being frozen and damaged.
Description
Technical field
The present invention relates to a kind of compound concrete frostproofer and preparation method thereof, belong to the concrete building material field.
Background technology
Concreting in cold-weather because concrete temperature and outside air temperature have difference, can produce heat exchange between concrete and ambient temperature; When envrionment temperature was very low, this heat exchange will reduce concrete temperature soon, as far as fresh concrete; The speed that temperature reduces has determined the size of hydration temperature, and temperature reduces faster, and the growth of concrete strength is slower; When concrete too early endure cold after, intensity just can not increase again, still the free water content at inside concrete is also just high; Frost-heave force after freezing is bigger with regard to, and concrete just damages easily, and the reason that concrete strength reduces mainly is that volume increased after water freezed; Frost heave stress just produces the crack thereupon increasing, concrete structure is damaged, and hour is the dangerous maximum moment at the first few of concrete placement; Concrete weather resistance possibly damaged concrete structure by first and second freeze-thaw cycle; And the excellent concrete antifreezer of use properties can make concrete delay the process of freezing, and prolongs critical strength, produces certain freezing tolerance.
Concrete freeze proofing at present commonly used mainly is electric heating process, steaming process, warm grid method, far infrared method, and uses frostproofer more economical, more convenient and be widely used.Through using the high performance concrete frostproofer to play the effect that improves intensity morning, prevents the concrete frost damage.
Summary of the invention
The objective of the invention is to provide a kind of compound concrete frostproofer,, play the effect that prevents the concrete frost damage to improve the temperature of concrete critical strength.
The present invention realizes through following technical scheme, it is characterized in that: mainly by polyoxyethylene glycol methylacrylic acid, rosin or the acid of korenyl semi-annular jade pendant sodium, Sodium hexametaphosphate 99, gather the hydroxy acid Sunmorl N 60S, suitable quantity of water is formed.
By its weight ratio by: polyoxyethylene glycol methylacrylic acid 20%～50%, rosin or the acid of korenyl semi-annular jade pendant sodium 0.1%～5%, Sodium hexametaphosphate 99 5%～30%, gather hydroxy acid Sunmorl N 60S 1%～2%, suitable quantity of water is formed.
Its preparation method is: accurately weigh by each group weight proportion, at first, in reaction kettle, add polyoxyethylene glycol methylacrylic acid diminishing mother liquor, heated and stirred is warming up to 30 ℃～50 ℃; Add then and gather the hydroxy acid Sunmorl N 60S, continue to stir 30min, in reaction kettle, add Sodium hexametaphosphate 99 and rosin or korenyl semi-annular jade pendant acid sodium again; Continue to stir 30min, last, in solution, add entry; Adjust strength of solution while stirring, discharging behind stirring 10～20min, packing.
Embodiment
Take by weighing each component by each composition weight proportioning, at first, in reaction kettle, add 30% polyoxyethylene glycol methylacrylic acid diminishing mother liquor, heated and stirred is warming up to 30 ℃～50 ℃; Add then 2% gather the hydroxy acid Sunmorl N 60S, continue to stir 30min, in reaction kettle, add 20% Sodium hexametaphosphate 99 and 2% korenyl semi-annular jade pendant acid sodium again; Continue to stir 30min, last, in solution, add 200% water; Adjust strength of solution while stirring, discharging behind stirring 10～20min, packing.
