Abstract

The invention discloses a method for preparing a sodium gluconate retarding, water-reducing and air-entraining agent. The product belongs to the field of a chemical construction material. By adopting the method, sodium gluconate, water, galactose, sodium pyrophosphate, sodium borate, a naphthalene-based superplasticizer and a rosin soap air-entraining agent are taken as materials; and a chemical reaction kettle is taken as a reaction container to prepare the sodium gluconate retarding, water-reducing and air-entraining agent. The method is simple in process, and mild in reaction condition; the product has good retarding, water-reducing and air-entraining effects; the peaceability of concrete can be obviously improved by adding the sodium gluconate retarding water-reducing and air-entraining agent to the concrete; the air content of the concrete is increased; the freezing resistance is increased; the water supply volume is reduced; and the crack resistance and the compressive property of the concrete are improved, and the method is suitable for continuous casting of a large batch of concrete.

Description

A kind of preparation method of Sunmorl N 60S slow setting diminishing air entrapment agent

Technical field

Product of the present invention belongs to the chemical building material field, relates in particular to a kind of preparation method of Sunmorl N 60S slow setting diminishing air entrapment agent.

Background technology

The effect of concrete retarder is to delay concrete coagulating time and to the admixture that later strength has no significant effect, mix retardant in concrete, its objective is in order to prolong the hydration and hardening time of cement.Sunmorl N 60S has obvious delayed coagulation to concrete after mixing concrete, the molecular formula of Sunmorl N 60S is C6H11O7Na, molecular weight is 218.14, be white crystals particle or powder at normal temperatures, very easily water-soluble, slightly be dissolved in and spill essence, be insoluble to ether, its main application is: 1. aspect medical, but acid base equilibrium in the balance the body; 2. as water quality stabilizer, obvious inhibition and scale inhibition ability are arranged; 3. be used as the steel surface clean-out system; 4. make the vial scavenger specially; 5. be used as cement blending agent: after adding the Sunmorl N 60S of some amount in the cement, can increase concrete plasticity-and intensity, and retardation is arranged, namely postpone concrete initial and final setting time; 6. can be used for electroplating the film manufacturing; 7. be used for food service industry, because it can prevent the generation of low sodium syndromes effectively, so can be used as foodstuff additive.Single Sunmorl N 60S is water-soluble to be exactly a kind of concrete retarder, in order further to strengthen its delayed coagulation and to satisfy concrete mortar to the demand of other performance, can be re-dubbed slow setting air entrapment agent, water reducer etc.The present invention is a kind of Sunmorl N 60S slow setting diminishing air entrapment agent, with Sunmorl N 60S, water, semi-lactosi, trisodium phosphate, borax, naphthalene series high-efficiency water-reducing agent, rosin soap air-entraining agent is raw material, take chemical reaction kettle as reaction vessel, prepare Sunmorl N 60S slow setting diminishing air entrapment agent, it is simple that the method has technique, reaction conditions is gentle, product has good slow setting, diminishing and bleed effect, add in the concrete and can significantly improve concrete workability, increase concrete 's air-containing, frost resistance strengthens, reduce water consumption, improve concrete anticracking and compressive property, suitable concrete continuous casting in enormous quantities.

Summary of the invention

The problem to be solved in the present invention provides the method that a kind of batch prepares Sunmorl N 60S slow setting diminishing air entrapment agent, this agent is with Sunmorl N 60S, water, semi-lactosi, trisodium phosphate, borax, naphthalene series high-efficiency water-reducing agent, rosin soap air-entraining agent is that raw material is produced, this preparation method's advantage is: production technique is simple, reaction conditions is gentle, product has good slow setting, diminishing and bleed effect, add in the concrete and can significantly improve concrete workability, increase concrete 's air-containing, frost resistance strengthens, reduce water consumption, improve concrete anticracking and compressive property, suitable concrete continuous casting in enormous quantities.The raw material of producing this product use has: Sunmorl N 60S 15%-17%, water 53%-55%, semi-lactosi 3%, trisodium phosphate 4%, borax 3%, naphthalene series high-efficiency water-reducing agent 10%, rosin soap air-entraining agent 10%.

The present invention can be achieved through the following technical solutions:

A kind of preparation method of Sunmorl N 60S slow setting diminishing air entrapment agent, its feature is made of following steps:

1. water is sent in the chemical reaction kettle, temperature is increased to 50 ℃, begin to stir, add while stirring Sunmorl N 60S, stir; Keep temperature-resistant, then add while stirring semi-lactosi, trisodium phosphate, borax, the timed interval of three kinds of raw material interpolations is 0.1 hour, after stirring, and standing and reacting 0.5 hour.

2. be cooled to and continue behind the normal temperature to stir, while stirring naphthalene series high-efficiency water-reducing agent is added chemical reaction kettle, stir and add rosin soap air-entraining agent after 0.3 hour, restir after 0.3 hour blowing obtain finished product.

The invention has the beneficial effects as follows: the preparation method that a kind of Sunmorl N 60S slow setting diminishing air entrapment agent is provided, this preparation method's technique is simple, reaction conditions is gentle, product has good slow setting, diminishing and bleed effect, add to and can significantly improve concrete workability, increase concrete 's air-containing, frost resistance enhancing, minimizing water consumption in the concrete, improve concrete anticracking and compressive property, suitable concrete continuous casting in enormous quantities.
