Abstract
The invention discloses a preparation method of an alkylphenol ethylene oxide condensation polymer air entraining agent, the product belongs to the chemical building material field. The air entraining agent is prepared by the raw materials of the alkylphenol ethylene oxide condensation polymer, rosin soap, carbolic acid, diethanolamine, sodium hydroxide and water, and is prepared by taking a chemical reaction vessel as a container. The preparation method has the advantages that the production technology is simple, the air entraining agent is added in the concrete for obviously improving the workability, pumpability, freeze-thaw resistance, endurance and impermeability of the concrete, the water-reducing rate of the concrete or mortar can be further increased, the water cement ratio is reduced, the air entraining agent can be used with a plurality of water reducers, antifreezing agents and pumping agents by compositing, and can be used with silicon powder, fly ash, fine slag, zeolite powder, expanding agent and the like, thereby the purpose for improving the concrete performance can be reached.
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 alkylphenol oxyethane polycondensate air-entraining agent.
Background technology
The main raw material that the preparation air entrapment agent uses is a class tensio-active agent, tensio-active agent is divided into anion surfactant, nonionogenic tenside and cats product, and what can prepare air entrapment agent is anion surfactant and nonionogenic tenside.The present invention is a kind of air entrapment agent of the preparation take nonionogenic tenside as main raw material, and nonionogenic tenside is of a great variety, and it quantitatively is only second to anion surfactant, is a large amount of important kinds of using of a class.Because nonionogenic tenside is not to exist with ionic condition in solution, so its stability is high, be not subject to the impact of acid, alkali, can mix use with the other types tensio-active agent, consistency is good, good solubility is all arranged in all kinds of SOLVENTS, and nonionogenic tenside has the performances such as good washing, dispersion, emulsification, foaming, wetting, protection against corrosion, is widely used for the industries such as weaving, papermaking, food, plastics, medicine, agricultural chemicals, coating, building materials.The kind of nonionogenic tenside has alkylphenol polyoxyethylene, alkylphenol oxyethane polycondensate, high-carbon fatty alcohol polyoxyethylene ether, polyoxyethylene carboxylate, polyoxyethylene amine etc.The present invention is a kind of air entrapment agent of the preparation take alkylphenol oxyethane polycondensate as main raw material, with alkylphenol oxyethane polycondensate, rosined soap, PHENOL 99.8 MIN ((CARBOLIC ACID)), diethanolamine, sodium hydroxide, water is raw material, prepare air entrapment agent take chemical reaction kettle as container, this preparation method's advantage is: production technique is simple, add this product in the concrete and can obviously improve concrete workability, pumpability, freeze-thaw resistance, weather resistance, impervious, can also further improve the water-reducing rate of concrete or mortar, reduce water cement ratio, this air entrapment agent can not only with multiple water reducer, frostproofer, the compound uses such as pumping agent, can also and silica flour, flyash, ground slag, zeolite powder, swelling agents etc. are common to be used, and reaches the further purpose of improving concrete performance.
Summary of the invention
The problem to be solved in the present invention provides the method that a kind of batch prepares alkylphenol oxyethane polycondensate air-entraining agent, this air entrapment agent is take alkylphenol oxyethane polycondensate as main raw material, produce air entrapment agent take rosined soap, PHENOL 99.8 MIN ((CARBOLIC ACID)), diethanolamine, sodium hydroxide, water as auxiliary material, this preparation method's advantage is: production technique is simple, add this product in the concrete and can obviously improve concrete workability, pumpability, freeze-thaw resistance, weather resistance, impermeability, can also further improve the water-reducing rate of concrete or mortar, reduce water cement ratio.The raw material of producing this product use has: alkylphenol oxyethane polycondensate 26%-28%, rosined soap 5%-7%, PHENOL 99.8 MIN ((CARBOLIC ACID)) 9%, diethanolamine 4%, sodium hydroxide 4%, water 50%.
The present invention can be achieved through the following technical solutions:
A kind of preparation method of alkylphenol oxyethane polycondensate air-entraining agent, its feature is made of following steps:
1. PHENOL 99.8 MIN ((CARBOLIC ACID)), diethanolamine are mixed in agitator tank.
2. water is sent into chemical reaction kettle, be warming up to 40 ℃, add while stirring alkylphenol oxyethane polycondensate to all dissolvings, temperature is increased to 85 ℃, add rosined soap, continued stirring reaction 1 hour.
3. keep temperature-resistant, continue to stir, the mixture of PHENOL 99.8 MIN ((CARBOLIC ACID)), diethanolamine is added chemical reaction kettle, after stirring, add sodium hydroxide after being cooled to normal temperature, continue to stir and stop after 0.3 hour stirring, discharging obtains finished product.
The invention has the beneficial effects as follows: the preparation method that a kind of alkylphenol oxyethane polycondensate air-entraining agent is provided, this preparation method's technique is simple, add this product in the concrete and can obviously improve concrete workability, pumpability, freeze-thaw resistance, weather resistance, impermeability, can also further improve the water-reducing rate of concrete or mortar, reduce water cement ratio.
