Abstract
The invention discloses a preparation method of a sorbitol retarding superplasticizer, which belongs to the field of chemical building materials. The invention aims to provide a method for batch production of the sorbitol retarding superplasticizer. The method adopts sorbitol, water, ethanol, salicylic acid, potassium gluconate, sodium citrate, and a sulfamate superplasticizer as raw materials, and takes a chemical reaction kettle as the reaction vessel to prepare the sorbitol retarding superplasticizer. The preparation method has a simple process. When the product is added into concrete, the concrete can achieve good retarding and water reducing effects, and can have the advantages of good pumpability, strong cohesiveness, low gas content, small bleeding rate, and good surface smoothness.
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 sorbyl alcohol efficient retarding and water reducing agent.
Background technology
Sorbyl alcohol is a kind of polyvalent alcohol, and molecular formula is C6H14O6, outward appearance be white crystalline powder, odorless, flavor slightly sweet, little have draw moist, soluble in water, be dissolved in ethanol.Sorbyl alcohol is a kind of broad-spectrum industrial chemicals, has very widely in industries such as food, daily use chemicals, medicine, chemical industry, buildings and uses.Sorbyl alcohol can make food keep fresh softness in foodstuffs industry, and the anticracking preservation agent that can be used as bread, cake uses; The sorbyl alcohol sugariness is lower than sucrose, is the good raw material of producing low sugariness sweet goods; Sorbitol Powder does not contain aldehyde radical, is difficult for oxidizedly, can prevent the sex change of carotenoid and edible-fat and protein.In daily chemical industry, sorbyl alcohol can be used as vehicle, wetting Agent for Printing Inks, frostproofer in toothpaste, in makeup as antidesiccant.Sorbyl alcohol can be used as ascorbic raw materials for production in medicine industry, and the dispersion agent, weighting agent, cryoprotectant, crystallization-preventive agent, Chinese medicine stablizer, wetting agent, capsule softening agent, the sweeting agent that also can be used as medicine use.In chemical industry, sorbyl alcohol can be used for production, polyethers production, additives for plastics production of the tensio-active agents such as sapn, tween etc.Use as concrete retarder in building trade.Be exactly a kind of retardant behind the water-soluble or ethanol of single sorbyl alcohol, its effect is better, in order further to strengthen retarding effect and to strengthen concrete mortar in the performance of the aspects such as diminishing, carry out composite to it.The present invention is a kind of efficient retarding and water reducing agent that uses the sorbyl alcohol in the polyvalent alcohol to prepare as main raw material, take sorbyl alcohol, water, ethanol, Whitfield's ointment, Potassium Gluconate, Trisodium Citrate, sulfamate high-effective water-reducing agent as raw material, prepare the sorbyl alcohol efficient retarding and water reducing agent take chemical reaction kettle as reaction vessel, this preparation method's technique is simple, can make concrete have good retarding effect and water-reducing effect after product adds in the concrete, the smooth finish that concrete pumpability is good, cohesiveness is strong, air content is few, bleeding rate is little, surperficial is good.
Summary of the invention
The problem to be solved in the present invention provides the method that a kind of batch prepares the sorbyl alcohol efficient retarding and water reducing agent, this efficient retarding and water reducing agent is as raw material take sorbyl alcohol, water, ethanol, Whitfield's ointment, Potassium Gluconate, Trisodium Citrate, sulfamate high-effective water-reducing agent, produce take chemical reaction kettle as reaction vessel, can make concrete have good retarding effect and water-reducing effect after product adds in the concrete, the smooth finish that concrete pumpability is good, cohesiveness is strong, air content is few, bleeding rate is little, surperficial is good.The raw material of producing this product use has: sorbyl alcohol 17%-19%, water 40%, ethanol 20%%, Whitfield's ointment 3%, Potassium Gluconate 2%, Trisodium Citrate 5%, sulfamate high-effective water-reducing agent 11%-13%.
The present invention can be achieved through the following technical solutions:
A kind of preparation method of sorbyl alcohol efficient retarding and water reducing agent, its feature is made of following steps:
1. water is sent in the chemical reaction kettle, temperature is increased 35 ℃, begin to stir, while stirring sorbyl alcohol is added chemical reaction kettle, be stirred to whole dissolvings, then add successively while stirring Whitfield's ointment, Potassium Gluconate, Trisodium Citrate, the timed interval of three kinds of raw material interpolations is 0.15 hour, the rear standing and reacting that stirs 1 hour.
2. continuation is stirred after being cooled to normal temperature, while stirring sulfamate high-effective water-reducing agent is added chemical reaction kettle, stirs after 0.5 hour ethanol is added, and restir 0.2 hour stops to stir blowing and obtains finished product.
The invention has the beneficial effects as follows: the preparation method that a kind of sorbyl alcohol efficient retarding and water reducing agent is provided, this preparation method's technique is simple, can make concrete have good retarding effect and water-reducing effect after product adds in the concrete, the smooth finish that concrete pumpability is good, cohesiveness is strong, air content is few, bleeding rate is little, surperficial is good.
