Abstract
The invention discloses a preparation method for a rosin resin air entraining agent. The rosin resin air entraining agent belongs to the field of chemical industry/building materials. The invention relates to the rosin resin air entraining agent used for concrete, and the rosin resin air entraining agent is prepared by taking rosin resin, sodium carbonate, carbonic acid, calcium formate, dilute sulphuric acid and water as raw materials. The preparation method has the advantages that the production process is simple; the rosin resin air entraining agent is non-toxic, and after the rosin resin air entraining agent is used, the peaceability, the flowability, the water-retaining property, the cohesiveness, the durability, the corrosion resistance and the freezing resistance of a concrete mixture can be obviously improved.
Description
Technical field
Product of the present invention belongs to the chemical building material field, relates in particular to a kind of preparation method of Gum Rosin air entrapment agent.
Background technology
Air entrapment agent refer to concrete in whipping process, can introduce a large amount of evenly, the admixture of the micro-bubble of stablizing and sealing, bubble diameter is generally 0.02-1.0mm, air entrapment agent is mainly used in has the concrete works that blends freeze proof requirement than high resistance, improve concrete durability, also can be used to improve pumping, because air entrapment agent causes concrete 's air-containing to improve, the effective stressed area of concrete reduces, concrete intensity will descend to some extent, general every increase by 1% air content, ultimate compression strength descends about 5%, and folding strength descends 2%～3%, so the volume of air entrapment agent must strictly be controlled by air content test.The major function of air entrapment agent is: the workability of improving concrete mix, in mixture, the micro-bubble of sealing can play the ball effect mutually, reduces the friction resistance between aggregate, thereby improves concrete flowability, if keep mobile constant, then can reduce water consumption, the air content of general every increase by 1% can reduce water consumption 6%-10%, because a large amount of micro bubble can adsorb the stable moisture film of one deck, thereby weakened concrete bleeding, so can improve concrete water-retentivity and cohesiveness; Improve concrete durability, because a large amount of micro bubbles stops up and cut off the capillary porosity duct in the concrete, simultaneously because bleeding is few, the hole seam that bleeding causes also reduces, thereby can greatly improve concrete anti-permeability performance, improve corrosion resistance and weathering resistance performance; On the other hand, reduce owing to be communicated with pore, water-intake rate is corresponding to be reduced, and the internal water pressure that causes when can buffered water freezing, thereby frost resistance is improved greatly.Air entrapment agent commonly used has Gum Rosin, benzene sulfonamide alkali salt, fatty alcohol sulfonate etc., and volume is generally 0.005%-0.01%.The present invention is a kind of Gum Rosin air entrapment agent, produce air entrapment agent take Gum Rosin, yellow soda ash, carbonic acid, calcium formiate, dilute sulphuric acid, water as raw material, this preparation method's advantage is: production technique is simple, product is nontoxic, can obviously improve workability, flowability, water-retentivity, cohesiveness, weather resistance, erosion resistance, the frost resistance of concrete mix after the use.
Summary of the invention
The problem to be solved in the present invention provides the method that a kind of batch prepares the Gum Rosin air entrapment agent, this Gum Rosin air entrapment agent is take Gum Rosin as main raw material, take yellow soda ash, carbonic acid, calcium formiate, dilute sulphuric acid, water as come the Gum Rosin air entrapment agent as auxiliary material, this preparation method's advantage is: production technique is simple, product is nontoxic, is applicable to various cement.The raw material of producing this product use has: Gum Rosin 27%-28%, yellow soda ash 8%-9%, carbonic acid 6%, calcium formiate 5, dilute sulphuric acid 3%, water 50%.
The present invention can be achieved through the following technical solutions:
A kind of preparation method of Gum Rosin air entrapment agent, its feature is made of following steps:
1. Gum Rosin is broken for Powdered.
2. carbonic acid and calcium formiate are mixed in the first stirred vessel.
3. water is sent into the second stirred vessel, be heated to 45 ℃, add while stirring yellow soda ash to all dissolvings, temperature is increased to 85 ℃, add the Gum Rosin powder, be stirred to whole dissolvings, then the mixture with the carbonic acid in the first stirred vessel and calcium formiate adds the second stirred vessel, even blend.
4. continue to stir, be cooled to normal temperature, to the 8-9, stop to stir discharging with the dilute sulphuric acid adjust pH, obtain finished product.
The invention has the beneficial effects as follows: the preparation method that a kind of Gum Rosin air entrapment agent is provided, this preparation method's technique is simple, product is nontoxic, can obviously improve workability, flowability, water-retentivity, cohesiveness, weather resistance, erosion resistance, the frost resistance of concrete mix after the use.
