Abstract
The invention relates to the technical field of fine chemical engineering, and specifically relates to a building cement composite liquid grinding aid. The liquid grinding aid is composed of the following components by the weight percentage: 20-30% of fly ash, 12-18% of triethanolamine, 5-8% of anhydrous sodium sulphate, 10-20% of an aminobenzene sulfonic acid sodium salt water reducing agent, 5-10% of sodium lignin sulfonate, 5-10% of calcium sulfate, 1-5% of sodium gluconate, and the balance water. The invention aims to provide the building cement composite liquid grinding aid with good strength and convenient use.
Description
Technical field
The present invention relates to the technical field of fine chemistry industry, specifically a kind of construction cement composite fluid grinding aid.
Background technology
Current domestic water cement grinding aids product has powder and liquid two kinds of forms.Because liquid product is easy to use, only needs increase storage tank and a microprocessor pump drive, just can add smoothly, do not need complicated heavy equipment, be therefore widely used gradually.The formula of existing liquid cement grinding additive forms the mainly single or combination product such as trolamine class, ethylene glycol, acetate.Due to these products, have volume few, liquid meter adds convenient, improves mill grinding efficiency 10 ~ 20%, saves unit time power consumption, improves the mobility of cement powder, is conducive to bulk shipment and storage, therefore cement factory uses very general abroad.At present, many cement grinding aids ignore the difference of grinding process and grinding material usually, grinding system, mill structure, grinding element, process operation parameter etc. are not adjusted targetedly, grinding aid product function is single, not strong to cement production process condition adaptability, cause result of use not good, unstable product quality.
Summary of the invention
The object of this invention is to provide the construction cement composite fluid grinding aid that a kind of intensity is good, easy to use.
The technical solution used in the present invention is, a kind of construction cement composite fluid grinding aid, described each weight percentages of components is as follows: the sodium salt water reducer 10-20% of flyash 20-30%, trolamine 12-18%, Sodium sulfate anhydrous.min(99) 5-8%, aniline sulfonic acid, sodium lignosulfonate 5-10%, calcium sulfate 5-10%, Sunmorl N 60S 1-5%, surplus are water.
Advantage of the present invention is the effect improving cement early strength and increase cement later strength.
Embodiment
The present invention is further described with the following Examples.
Embodiment 1, a kind of construction cement composite fluid grinding aid, described each weight percentages of components is as follows: the sodium salt water reducer 10% of flyash 30%, trolamine 12%, Sodium sulfate anhydrous.min(99) 8%, aniline sulfonic acid, sodium lignosulfonate 5%, calcium sulfate 10%, Sunmorl N 60S 1%, surplus are water.
Embodiment 2, a kind of construction cement composite fluid grinding aid, described each weight percentages of components is as follows: the sodium salt water reducer 20% of flyash 20%, trolamine 18%, Sodium sulfate anhydrous.min(99) 5%, aniline sulfonic acid, sodium lignosulfonate 10%, calcium sulfate 5%, Sunmorl N 60S 5%, surplus are water.
Embodiment 3, a kind of construction cement composite fluid grinding aid, described each weight percentages of components is as follows: the sodium salt water reducer 15% of flyash 25%, trolamine 15%, Sodium sulfate anhydrous.min(99) 6.5%, aniline sulfonic acid, sodium lignosulfonate 7.5%, calcium sulfate 7.5%, Sunmorl N 60S 3%, surplus are water.
Should be understood that this embodiment is only not used in for illustration of the present invention to limit the scope of the invention.In addition, should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the protection domain that the application's appended claims limits equally after having read the content that the present invention lectures.
