Abstract
The invention discloses an enhanced type cement composite grinding aid. The enhanced type cement composite grinding aid is prepared from the following materials in parts by weight: 48-88 parts of diethanol isopropanolamine, 5-28 parts of molasses, 5-22 parts of lignosulfonate, 0-15 parts of inorganic dispersing materials and 5-35 parts of water. The enhanced type cement composite grinding aid disclosed by the invention has beneficial effects as follows: the enhanced type cement composite grinding aid has characteristics of being scientific and practical, overcomes dependency of the cement grinding aid on triethanolamine and triisopropanolamine, has enhancing performances better than those of products which take the triethanolamine or the triisopropanolamine as the main material, satisfies needs of a cement plant on improving early-stage and later-stage strength of the cement, has remarkable economic and social benefits; and meanwhile, the enhanced type cement composite grinding aid disclosed by the invention is properly mixed with components such as the lignosulfonate, the molasses, sodium hexametaphosphate or sodium polyphosphate, and the like, so that comprehensive performances of the product are effectively perfected; and the materials are combined for use, so that the product performances can satisfy different requirements, and popularization value is wide.
Description
Technical field
The present invention relates to a kind of enhanced cement composite grinding aid.
Background technology
China is manufacture of cement and uses big country, needs to consume a large amount of resources such as Wingdale and a large amount of electric power, coal equal energy sources, and discharge the atmospheric polluting material of some amount in cement production process.In cement production process, the carrying capacity of environment of " calcination of chamotte " and " pulverizing cement " 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 three tons of left and right of the various materials of grinding, the energy consumption of grinding process accounts for 60～70% of the total power consumption of manufacture of cement.Cement industry will keep Sustainable development, must take measures, and reduces resource, energy consumption and reduces the discharge to environmentally hazardous substance, walks 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 cement grinding aid is that to improve mill grinding efficiency be main purpose, and this grinding aid has been 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 particle surface free energy, weaken material reunion, slimeball, be stained with wall effect, accelerate the grinding flow velocity of material, improve mill efficiency, thereby reduce ton cement grinding power consumption, increase ball mill unit-hour output, improve cement transportation performance, reach the object 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, as improve time of coagulation simultaneously, reduces cement water requirement, increases mortar or each age strength of concrete and volume stability etc.
At present conventional trolamine, tri-isopropanolamine be as the main raw material(s) of cement grinding aid, a kind of cement grinding aid as disclosed in Chinese patent 200610037601.5, its form component include trolamine, ethylene glycol, Ammoniom-Acetate,
Urea, unsaturated polyester resin and spent pulping liquor.The outstanding feature that adopts trolamine in cement grinding aid is to improve 1 day intensity of cement, but for 28 days and not contribution of intensity later; In a lot of cement grinding aids, also select tri-isopropanolamine to come 7 days, 28 days or later intensity of refinforced cement, but tri-isopropanolamine can not increase 1 day of cement or 7 days with interior early strength.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, provide a kind of and improve the early stage and later strength of cement products, and can improve the enhanced cement composite grinding aid of cement quality.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of enhanced cement composite grinding aid, this has composite grinding aids to be formed by weight ratio by following raw material: di-alcohol α-amino isopropyl alcohol is 48～88 parts, and molasses are 5～28 parts, and sulfonated lignin are 5～22 parts, inorganic dispersing material is 0～15 part, and water is 5～35 parts.
Described inorganic dispersing material is one or both in sodium polyphosphate and Sodium hexametaphosphate 99.
Described sulfonated lignin are lignosulfonic acid calcium salt or lignosulfonic acid magnesium salts.
The invention has the beneficial effects as follows:
The present invention has the feature of science practicality, overcome the dependence of cement grinding aid to trolamine and tri-isopropanolamine, strengthen the property simultaneously and be more better than take the product that trolamine or tri-isopropanolamine are main raw material(s), meet cement mill to improving cement in early days and the demand of later strength, there is significant economic and social benefit, the present invention simultaneously mixes sulfonated lignin in right amount, molasses, the component such as Sodium hexametaphosphate 99 or sodium polyphosphate, the effectively perfect over-all properties of product, the compound use of these materials makes product performance can meet different requirements, there is promotional value widely.
