Abstract
The invention discloses a liquid cement grinding aid, and belongs to the technical field of cement grinding aids. The liquid cement grinding aid is prepared from the following raw materials in percentage by weight: 15-22% of triethanolamine, 10-15% of dodecylbenzene, 10-15% of p-aminobenzene sulfonic acid, 1-3% of a sodium salt water reducing agent of aminobenzene sulfonic acid, 3-5% of sorbitol, 5-10% of triisopropanolamine, 3-5% of hydroxypropyl methyl cellulose, 3-5% of sodium lignin sulfonate, 5-10% of sodium humate, and the balance of water. According to the liquid cement grinding aid, through reasonable proportion of the raw materials, on the premise of less amount of admixture, the yield within a unit time can be up to 15% above, the cement strength can be increased to 3 MPa above for three days, and the cement strength can be increased to 5 MPa above for 28 days.
Description
Technical field
The invention belongs to cement grinding aid technical field, be specifically related to a kind of liquid cement grinding additive.
Background technology
Cement grinding aid is a kind of chemical additive improving cement grinding effect and performance, can significantly improve cement unit-hour output, each length of time strength of cement, improve its mobility.Cement grinding aid significantly can reduce the electrostatic adhesion bag ball phenomenon formed in grinding process, and can reduce the again coalescent trend of the ultra-fine grain formed in grinding process.Cement grinding aid also significantly can improve cement fluidity, improves the grinding effect of grinding machine and the grinding efficiency of powder separating machine, thus reduces grinding energy.The cement using grinding aid to produce has the coalescent trend of lower compacting, thus is conducive to the handling of cement, and can reduce the wall cling phenomenon of cement silo.
But cement grinding aid volume of the prior art is 0.08 ~ 0.1%, and volume is large, and exists and carry that to produce efficiency not high, to the early strength of cement and the later strength DeGrain that improve Wingdale.
Summary of the invention
For prior art Problems existing, the object of the invention is to design the technical scheme that a kind of liquid cement grinding additive is provided.
Described a kind of liquid cement grinding additive, is characterized in that being made up of the raw material of following weight percent: the sodium salt water reducer 1 ~ 3% of trolamine 15 ~ 22%, dodecylbenzene 10 ~ 15%, Sulphanilic Acid 10 ~ 15%, aniline sulfonic acid, sorbyl alcohol 3 ~ 5%, tri-isopropanolamine 5 ~ 10%, Vltra tears 3 ~ 5%, sodium lignosulfonate 3 ~ 5%, sodium humate 5 ~ 10%, surplus are water.
Described a kind of liquid cement grinding additive, is characterized in that being made up of the raw material of following weight percent: the sodium salt water reducer 2 ~ 3% of trolamine 16 ~ 20%, dodecylbenzene 12 ~ 14%, Sulphanilic Acid 12 ~ 14%, aniline sulfonic acid, sorbyl alcohol 3 ~ 4%, tri-isopropanolamine 6 ~ 8%, Vltra tears 3 ~ 4%, sodium lignosulfonate 3 ~ 4%, sodium humate 6 ~ 8%, surplus are water.
Described a kind of liquid cement grinding additive, is characterized in that being made up of the raw material of following weight part: the sodium salt water reducer 3% of trolamine 18%, dodecylbenzene 13%, Sulphanilic Acid 13%, aniline sulfonic acid, sorbyl alcohol 4%, tri-isopropanolamine 7%, Vltra tears 4%, sodium lignosulfonate 3%, sodium humate 7%, surplus are water.
The preparation method of above-mentioned a kind of liquid cement grinding additive: the hot water injecting 30 ~ 40 DEG C in a kettle., then the raw material of described weight percent is added, stir.
Above-mentioned a kind of liquid cement grinding additive, by the rational proportion of each raw material, under the prerequisite that volume is few, the output improved in the unit time reaches more than 15%, within 3 days, can improve more than strength of cement 3MPa, within 28 days, can improve strength of cement 5 more than MPa.
