Abstract
The invention relates to a cement material, in particular to a liquid cement grinding aid. The liquid cement grinding aid comprises the following components in percentage by weight: 20-30 percent of an aqueous solution of sodium salt of acrylic acid-maleic anhydride copolymer, 15-25 percent of a sodium salt water-reducing agent of aminobenzene sulfonic acid, 5-10 percent of sodium lignin sulfonate, 5-10 percent of glycol, 10-15 percent of triethanolamine, 1-5 percent of sodium gluconate and the balance of water. The invention aims to provide the liquid cement grinding aid with the effect of improving the early strength and later strength of cement.
Description
Technical field
The present invention relates to cement material, specifically a kind of liquid cement grinding additive.
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 a kind of liquid cement grinding additive improving the effect of cement early strength and increase cement later strength.
The technical solution used in the present invention is, a kind of liquid cement grinding additive, described each weight percentages of components is as follows: sodium salt of acrylic acid-co-maleic anhydride aqueous solution 20-30%, the sodium salt water reducer 15-25% of aniline sulfonic acid, sodium lignosulfonate 5-10%, ethylene glycol 5-10%, trolamine 10-15%, Sunmorl N 60S 1-5%, surplus is 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 liquid cement grinding additive, described each weight percentages of components is as follows: the sodium salt of acrylic acid-co-maleic anhydride aqueous solution 20%, the sodium salt water reducer 15% of aniline sulfonic acid, sodium lignosulfonate 5%, ethylene glycol 5%, trolamine 10%, Sunmorl N 60S 1%, surplus is water.
Embodiment 2, a kind of liquid cement grinding additive, described each weight percentages of components is as follows: the sodium salt of acrylic acid-co-maleic anhydride aqueous solution 25%, the sodium salt water reducer 120% of aniline sulfonic acid, sodium lignosulfonate 12.5%, ethylene glycol 7.5%, trolamine 12.5%, Sunmorl N 60S 3.5%, surplus is water.
Embodiment 3, a kind of liquid cement grinding additive, described each weight percentages of components is as follows: the sodium salt of acrylic acid-co-maleic anhydride aqueous solution 30%, the sodium salt water reducer 25% of aniline sulfonic acid, sodium lignosulfonate 10%, ethylene glycol 10%, trolamine 15%, Sunmorl N 60S 5%, surplus is 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.
