Abstract
The invention patent relates to an enhanced cement composite grinding aid, pertaining to a cement additive. The enhanced cement composite grinding aid has the following main ingredients in percentagesby weight: 45 percent to 90 percent of diethanol isopropanolamine, 10 percent to 30 percent of molasses, 5 percent to 20 percent of lignosulphonate, 0 percent to 15 percent of inorganic dispersant and 0 percent to 30 percent of water. The main ingredient of the grinding aid, diethanol isopropanolamine, is a substitute for trolamine and triisopropanolamine in respect of property and the property thereof is superior to single trolamine or triisopropanolamine grinding aid. The application of the enhanced cement composite grinding aid to cement production can effectively increase output per machine hour of a grinder, improve cement strength in early period and later period, and reduce cement production cost.
Description
Technical field
Patent of the present invention relates to a kind of enhanced cement composite grinding aid, belongs to cement additire.
Background technology
China is manufacture of cement and consumption big country, needs to consume a large amount of resources and the energy in the manufacture of cement, and physical environment is discharged the atmospheric polluting material of some amount.In cement production process, the carrying capacity of environment of " clinker burning " and " cement grinding " these two process procedures is the most serious, wherein grinding is the significant process of manufacture of cement, one ton of cement of every production, need about three tons of the various materials of grinding, the power consumption of grinding process accounts for 60～70% of the total power consumption of manufacture of cement.Cement industry will keep sustainable development, then must take measures, and reduces resource, energy consumption and minimizing to the discharging of environmentally hazardous substance, walks the energy-saving and emission-reduction road.The approach of Cement industry energy-saving and emission-reduction is a lot, and using cement grinding aid is the method for the simplest and instant effect.
Traditional grinding aid is to be main purpose to improve mill grinding efficiency, and this grinding aid has used for many years, and cement grinding process is had a very important role.It can change the electric property of cement particle surface, reduce the particle surface free energy, weaken material reunion, slimeball, be stained with the wall effect, accelerate the grinding flow velocity of material, improve mill efficiency, thereby reduce ton cement grinding power consumption, increase the ball mill unit-hour output, improve the cement transportation performance, reach the purpose of saving ton manufacture of cement cost.In recent years, the cement additire of a new generation is widely used, and it not only has all advantages of traditional grinding aid, can improve cement quality simultaneously, as improve time of coagulation, reduces the cement water requirement, increases mortar or each age strength of concrete etc.
Trolamine at present commonly used, tri-isopropanolamine are as the main raw material(s) of cement grinding aid, as Chinese patent 200610037601.5 disclosed a kind of cement grinding aids, it is formed component and includes trolamine, ethylene glycol, Ammoniom-Acetate, urea, insatiable hunger and close polyester resin and spent pulping liquor.Adopting the outstanding feature of trolamine in the cement grinding aid is to improve 1 day cement mortar strength of cement, but for 28 days and not contribution of intensity later on; 7 days, 28 days or later intensity also selecting for use tri-isopropanolamine to come refinforced cement in a lot of cement grinding aids, but tri-isopropanolamine can not increase 1 day of cement or 7 days with interior early strength.
Summary of the invention
The present invention is based on the deficiency of existing cement grinding aid technology, provides a kind of except that have good grinding-aid effect in cement production process, can also effectively improve cement products and reach later strength in early days, and can improve the enhanced cement composite grinding aid of cement quality.
The technical scheme that the present invention is adopted for achieving the above object is: a kind of enhanced cement composite grinding aid, its main body includes di-alcohol Yi Bingchunan, molasses and sulfonated lignin.
It is that the lignosulfonic acid calcium salt is or/and the lignosulfonic acid magnesium salts that the described sulfonated lignin of technique scheme are selected.
As improvement of the technical scheme, this enhanced cement composite grinding aid also comprises inorganic dispersant and water, and inorganic dispersant can be one or both in sodium polyphosphate, the Sodium hexametaphosphate 99.
The content of each component is that di-alcohol Yi Bingchunan weight percent is 45～90% in the technical solution of the present invention, the molasses weight percent is 10～30%, the sulfonated lignin weight percent is 5～20%, and the inorganic dispersant weight percent is 0～15%, and the weight percent of water is 0～30%.
The present invention has overcome the dependence of cement grinding aid to trolamine and tri-isopropanolamine, strengthening the property simultaneously, more to be better than with trolamine or tri-isopropanolamine be the product of main raw material(s), satisfy the cement mill to improving the demand that cement reaches later strength in early days, have remarkable economical and social benefit.The present invention mixes components such as sulfonated lignin, molasses, Sodium hexametaphosphate 99 or sodium polyphosphate in right amount, effectively perfect The comprehensive performance, and the compound use of these materials makes product performance can satisfy different requirements.
Embodiment
It is the cement grinding aid of di-alcohol Yi Bingchunan that purport of the present invention is to protect a kind of main body composition, an amount of simultaneously other components that add, and sulfonated lignin, molasses, Sodium hexametaphosphate 99 or sodium polyphosphate improve The comprehensive performance.The content of cement grinding aid each component is that di-alcohol Yi Bingchunan weight percent is 45～90%, the molasses weight percent is 10～30%, the sulfonated lignin weight percent is 5～20%, and the inorganic dispersant weight percent is 0～15%, and the weight percent of water is 0～30%.
Di-alcohol Yi Bingchunan (N wherein, two (2-the hydroxyethyl)-2-Propanolamines of N-) be main grinding aid composition, it is as active material, mainly bring into play grinding aid, improving cement flows and enhanced effect, compare with trolamine, tri-isopropanolamine, its remarkable superior performance is effectively to improve 1 day, 3 days, 7 days, 28 days intensity of cement simultaneously, reduces the hardened cement porosity simultaneously, improves endurance performance of concrete; Sulfonated lignin adopt calcium salt or/and magnesium salts, sulfonated lignin have aryl nucleus, connect to nonpolar long-chain by propyl, contain polar functional group on the chain, as sulfonic group, methoxyl group, hydroxyl and carbonyl etc., this structure makes it have dipolar nature, presents surfactivity, be a kind of strong tensio-active agent, it can weaken particulate intensity and stop particles coalesce; Molasses are poly-hydroxy organism, are a kind of good grinding aids, can effectively improve cement quality simultaneously, as reducing the cement water requirement, improve pore structure of cement stone etc.; Sodium polyphosphate and Sodium hexametaphosphate 99 are inorganic dispersants, and grinding aid performance is preferably still arranged under hot conditions.Grinding aid main body composition di-alcohol Yi Bingchunan of the present invention is the substitute of trolamine and tri-isopropanolamine on performance, and its enhancing and grinding-aid effect are remarkable; An amount of other component sulfonated lignin of the present invention, molasses, Sodium hexametaphosphate 99 or sodium polyphosphate mixed The comprehensive performance effectively perfect, the compound use of these materials makes product performance can satisfy different requirements.
