Min, dry ball milling 6-8h, add hydroxypropyl Oxytarch succinate sodium, dodecylbenzene sodium sulfonate, potassium humate, control
Ratio of grinding media to material processed is 4-7:1, and rotating speed is 500-700r/min, dry ball milling 4-6h, adds remaining raw material, and control ratio of grinding media to material is 5-
8:1, rotating speed is 300-500r/min, dry ball milling 5-7h；
(2) joining in ultrasonic wave concussion device by the compound that step (1) ball milling obtains, control ultrasonic power is 300-
400W, supersonic frequency is 20-40KHz, shakes 30-50min, then proceeds in magnetic stirring apparatus, and control rotating speed is 2000-
2500r/min, stirs 10-15min, then to control rotating speed is 1000-1500r/min, stirs 5-10min, stops stirring, pack,
It is finished product.
The method have the benefit that
The present invention use aliphatic hydroxyl sulphonate condensation substance, sodiumβ-naphthalenesulfonate formaldehyde condensation products, sulfonated phenol formaldehyde resin,
The raw materials such as MPEGMA-MA-SMAS terpolymer, ammonium alginate, potassium humate, hydroxypropyl Oxytarch succinate sodium are made
Water reducer not only there is stronger slump reserve capability, overcome the shortcoming that high efficiency water reducing agent loss of slump is big, also have
Have that peptizaiton is strong, water-reducing rate is high, early strength is high, the advantage that anti-permeability performance is good, it is particularly well-suited to prepare high-thin arch dam, high-strength
