Abstract
The invention discloses a kind of sodium gluconate slow setting air entraining agent, which belongs to chemical building material field；Produce the raw material that the product uses includes: sodium gluconate 14-16%, water 66%, rosin resin air entraining agent 8-10%, petroleum sodium sulfonate air entraining agent 10% by weight ratio, by blending at different temperatures come finished product, product has good slow setting, bleed effect, the workability of concrete can be significantly improved, increase concrete 's air-containing, frost resistance enhancing, reduce water consumption by being added in concrete, improve concrete anticracking and compressive property, is suitable for the continuous casting of high-volume concrete.
Description
Technical field
Product of the present invention category chemical building material field more particularly to a kind of sodium gluconate retarding and water-reducing air-entraining agent and its preparation side
Method.
Background technique
The effect of concrete retarder be delay concrete coagulating time and to the additive that later strength has no significant effect,
Retarder is mixed in concrete, its purpose is to extend the hydration and hardening time of cement, sodium gluconate mixes concrete
Have apparent deferred action to concrete afterwards, it is exactly a kind of concrete retarder that single sodium gluconate, which is dissolved in water, in order into
One step enhances its deferred action and meets the needs of concrete mortar is to other performance, can be re-dubbed slow setting air entraining agent.The present invention
It is a kind of sodium gluconate slow setting air entraining agent, is with sodium gluconate, water, rosin resin air entraining agent, petroleum sodium sulfonate air entraining agent
Raw material, using chemical reaction kettle as reaction vessel, to prepare sodium gluconate slow setting air entraining agent, this method has simple process, instead
Answer mild condition, product has good slow setting, bleed effect, and it is can significantly improving concrete and easy to be added in concrete
Property, increase concrete 's air-containing, frost resistance enhancing, improve concrete anticracking and compressive property, be suitable for the company of high-volume concrete
Continuous casting.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of sodium gluconate slow setting air entraining agents and preparation method thereof, produce the production
The raw material that product use includes: sodium gluconate 14-16%, water 66%, rosin resin air entraining agent 8-10%, petroleum sulphur by weight ratio
Sour sodium air entraining agent 10%.
The present invention can be achieved through the following technical solutions:
(1) water of formula ratio is sent into chemical reaction kettle, temperature is increased to 44-46 DEG C, starts to stir, be added while stirring
The sodium gluconate of formula ratio is stirred to react 0.2-0.3 hours.
(2) continue to stir after being cooled to room temperature, while stirring draw rosin resin air entraining agent, the petroleum sodium sulfonate of formula ratio
Chemical reaction kettle is added in gas agent, stops stirring to get finished product after stirring 0.2-0.3 hours.
Preferably, the purity of the sodium gluconate is 80%.
Preferably, the purity of the rosin resin air entraining agent is 60%.
Preferably, the purity of the petroleum sodium sulfonate air entraining agent is 65%.
The beneficial effects of the present invention are: providing a kind of sodium gluconate slow setting air entraining agent and preparation method thereof, the preparation
Method and process is simple, and reaction condition is mild, and product has good slow setting, bleed effect, and being added in concrete significantly to mention
The workability of high concrete increases concrete 's air-containing, frost resistance enhancing, improves concrete anticracking and compressive property, is suitable for big
The continuous casting of batch concrete.
