Abstract
The invention discloses a kind of sodium metasilicate concrete accelerator and its preparation method, which belongs to chemical field；It produces the raw material that the product uses to calculate by weight ratio, comprising: sodium metasilicate 26-27%, aluminum sulfate 6-7%, sodium carbonate 4%, injection concrete adhesion agent 4%, water 59%；The water of formula ratio is sent into chemical reaction kettle, adjusts the temperature to 35 DEG C -40 DEG C while stirring, the sodium metasilicate of formula ratio is slowly added, until all dissolutions；It is cooled to room temperature, continues to stir, chemical reaction kettle successively is added in the aluminum sulfate of formula ratio, sodium carbonate and injection concrete adhesion agent, stirs 10-15 minutes, obtains finished product；Product is suitable for being added in silicate concrete, and having condenses concrete rapidly, early strong effect, and small toxicity.
Description
Technical field
Product of the present invention belongs to chemical field more particularly to a kind of preparation method of sodium metasilicate concrete accelerator.
Background technique
Concrete accelerator is concrete to be made to condense the additive of hardening rapidly in a kind of incorporation concrete, and appearance is powder
Shape solid or liquid, its effect are the hydration and hardenings for accelerating cement, form enough intensity in a short period of time, to guarantee
The requirement of special construction is indispensable additive in special concrete pouring construction.Sodium metasilicate is concrete batching speed
One of the raw material of solidifying agent, the thick water solution of sodium metasilicate is waterglass, also known as sodium silicate, in cement, concrete, fire proofed wood
The industrial circles such as material, grease and leather processing have a large amount of application, are especially suitable for being used in portland cement.Single inclined silicon
There is sour sodium certain rapid hardening effect need to add partial supplementary material to keep its rapid hardening effect more preferable.The present invention is one kind with inclined silicon
Sour sodium, aluminum sulfate, sodium carbonate, injection concrete adhesion agent are raw material, are prepared by the method blended at a certain temperature mixed
Solidifying soil accelerator, the preparation method simple process, production cost is low, good product quality, and application method is easy, is particularly suitable for adding
Into silicate concrete, having condenses concrete rapidly, early strong effect, and small toxicity.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of sodium metasilicate concrete accelerator and its preparation methods, produce the production
The raw material that product use includes: sodium metasilicate 26-27%, aluminum sulfate 6-7%, sodium carbonate 4%, injection concrete adhesion by weight ratio
Agent 4%, water 59%.
The present invention can be achieved through the following technical solutions:
(1) water of formula ratio is sent into chemical reaction kettle, adjusts the temperature to 35 DEG C -40 DEG C while stirring, formula is slowly added
The sodium metasilicate of amount, until all dissolutions.
(2) it is cooled to room temperature, continues to stir, successively by the aluminum sulfate of formula ratio, sodium carbonate and injection concrete adhesion agent
Chemical reaction kettle is added, stirs 10-15 minutes, obtains finished product.
Preferably, the sodium metasilicate purity is 85%.
The beneficial effects of the present invention are: providing a kind of sodium metasilicate concrete accelerator and its preparation method, the preparation
Method and process is simple, and production cost is low, good product quality, and product is suitable for being added in silicate concrete, and having makes concrete
Condensation rapidly, early strong effect, and small toxicity.
Specific embodiment
Embodiment 1

Chemical reaction kettle is added with the injection concrete adhesion agent that total amount is 4% is accounted for for 4% sodium carbonate in amount, stirs 10 minutes, obtains into
Product.
Embodiment 2
The water that total amount is 59% will be accounted for and be sent into chemical reaction kettle, 37.5 DEG C are adjusted the temperature to while stirring, be slowly added and account for total amount
For 26.5% sodium metasilicate, dissolved up to whole；It is cooled to room temperature, continues to stir, will successively account for sulfuric acid of the total amount for 6.5%
Aluminium accounts for sodium carbonate and account for the injection concrete adhesion agent addition chemical reaction kettle that total amount is 4% that total amount is 4%, stirs 12.5 points
Clock obtains finished product.
Embodiment 3
The water that total amount is 59% will be accounted for and be sent into chemical reaction kettle, adjust the temperature to 40 DEG C while stirring, slow addition accounts for total amount and is
27% sodium metasilicate, until all dissolutions；It is cooled to room temperature, continues to stir, it is total successively to account for aluminum sulfate, Zhan that total amount is 6%
Chemical reaction kettle is added with the injection concrete adhesion agent that total amount is 4% is accounted for for 4% sodium carbonate in amount, stirs 15 minutes, obtains into
Product.
Claims (2)
