Abstract
The invention relates to a novel cement grinding aid, and belongs to the technical field of building materials. The cement grinding aid is compounded from modified propanetriol, and is prepared from the following components in parts by weight: 15-35 parts of triethanolamine, 10-15 parts of ethylene glycol, 5-10 parts of sodium dodecyl sulfate, 5-10 parts of modified propanetriol and 30-50 parts of water. The cement grinding aid is simple in process and low in preparation cost, has better grinding aiding performance on cement, and can improve the strength of cement.
Description
Technical field
The present invention relates to a kind of novel concrete grinding aid, belong to building material technical field.
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; Significantly can reduce the electrostatic adhesion bag ball phenomenon formed in grinding process, and the again coalescent trend of the ultra-fine grain formed in grinding process can be reduced; Also significantly can improve cement fluidity, improve the grinding effect of grinding machine and the grinding efficiency of powder separating machine, thus reduce 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.As a kind of chemical additive, grinding aid can improve concrete scroll and excite aquation power, thus improves cement early strength and later strength, improves cement performance.
Current domestic common cement grinding aid has liquid and solid two class, and due to of a great variety, different properties, result of use exists larger difference with the difference of physical property, processing condition.Trolamine is maximum a kind of cement grinding aid now, it can directly as grinding aid use, also can with polyvalent alcohol compound use, can cement output be improved, and increase strength of cement, but, due to expensive, source shortage, Difficulty.
Granulated blast-furnace slag has higher lateral reactivity; but its not easily grinding; after slag reaches certain fineness; levigate quite difficult further again, but the slag micropowder after grinding has again very high activity, can use together with cement; reduce the volume of cement clinker; grinding aids a lot of is at present all be not clearly for cement clinker to the effect of slag, and characteristic and the cement of slag are very different, and the grinding aid being applicable to cement might not be applicable to slag.Therefore, in slag milling process, add the grinding aid of applicable slag, thus significantly improve mill efficiency, make it reach higher specific surface area and suitable fineness, become the emphasis of research both at home and abroad.
Chinese invention " a kind of high-efficiency energy-saving cement grinding aid and preparation method thereof ", application number 201010283101.6 discloses a kind of preparation method of composite grinding aids, but this grinding aid is to fineness, the SO of cement
3content, clinker quality have strict control, and subject range is narrower; Chinese invention " cement grinding aid ", application number 201410658003.4 discloses a kind of high pollution thing---cement grinding aid prepared by black liquid compound, but complex process; Chinese invention " cement grinding aid ", application number 201410535707.2 discloses a kind of preparation method of polyether glycol of applicable cement grinding aid, it is a kind of Polymer Synthesizing grinding aid, but prepare by modification glycerol compound, grinding aid slag to good grinding-aid effect have not been reported.
Summary of the invention
The object of this invention is to provide a kind of novel concrete grinding aid, technique is simple, and cost of manufacture is low, to the grinding aid better performances of cement, and can improve the intensity of cement.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of novel concrete grinding aid, is made up of the component of following weight part: trolamine 15 ~ 35 parts, ethylene glycol 10 ~ 15 parts, sodium laurylsulfonate 5 ~ 10 parts, modification glycerol 5 ~ 10 parts, 30 ~ 50 parts, water.
The preparation method of described modification glycerol is: in the four-hole boiling flask that stirring, condensing works are housed, and adds glycerol, trolamine, formic acid, is warming up to 60 ~ 70 DEG C, adds sulfuric acid, then is warming up to 85 ~ 88 DEG C, and reaction 2 ~ 3h, namely obtains modification glycerol.
The add-on of described glycerol, trolamine, formic acid is 1 ~ 1.5:2 ~ 2.5:1.4 ~ 2.1 by weight percentage.
The add-on of described sulfuric acid is 0.15 ~ 0.45% of modification glycerol weight.
The invention has the beneficial effects as follows:
1. present invention process is simple, and cost of manufacture is low;
2. pair slag has good grinding-aid effect, can shorten grinding time, reduces energy consumption;
3. the grinding aid better performances of cement, strong adaptability, can be applicable to the cement of different grades;
4. cement specific surface area can be improved, the intensity of refinforced cement.
