Abstract
The invention discloses a kind of cement grinding aid, raw material by weight includes：Hexadecanol 1-3 parts, ethylene glycol 1-3 parts, glycerine 1-3 parts, ethyl acetate 1-3 parts, stearic acid 11-15 parts, zeolite powder 15-25 parts, linseed oil 1-4 parts, 1-4 parts, sucrose 3-5 parts of silica nanometer powder.Raw material of the present invention is easy to get, non-volatile, and without dirt evil, processing prepares simple, with low cost, improves fine particle content in cement, improves grinding aid efficiency, reduces production cost, has saved power consumption；Also improve enhancing effect simultaneously.
Description
Technical field
The present invention relates to a kind of cement additive, specifically a kind of cement grinding aid.
Background technology
Current China manufacture of cement is generally divided into three steps, prepares raw material, calcination of chamotte, pulverizing cement.Wherein electric energy more than 95% is all wasted because changing into heat energy during pulverizing cement；When cement grinding attenuates, easy adhesive aggregation is agglomerating simultaneously reduces mill efficiency.In order to improve cement grinding efficiency, power consumption in cement pulverizing course is reduced, increase the addition content of mixing material, so as to reduce cement cost, typically to add cement grinding aid.
The grinding aid produced on present society, though there is grinding aid function, more is to play a part of excited cement mixing material lateral reactivity, the grinding aid for being exclusively used in clinker grinding is not produced, although the addition content of mixing material can be increased, reduces cost can influence cement later strength；And the cement grinding aid of function admirable is relatively costly, wherein most is again that small organic molecule is mixed, the less stable of this kind of grinding aid, using effect fluctuation is larger, and applicable surface is narrower.Usually need to increase the consumption of grinding aid to improve yield, improve manufacture of cement cost.The existing grinding aid of China still suffers from many problems in use, and such as villaumite brings very big potential safety hazard to the durability of cement and concrete；Grinding aid quality is unstable, and volume is big, so as to cause cement quality fluctuation etc..
The content of the invention
It is an object of the invention to provide a kind of cement grinding aid, to solve the problems, such as to be proposed in above-mentioned background technology.
To achieve the above object, the present invention provides following technical scheme：
A kind of cement grinding aid, raw material by weight includes：Hexadecanol 1-3 parts, ethylene glycol 1-3 parts, glycerine 1-3 parts, ethyl acetate 1-3 parts, stearic acid 11-15 parts, zeolite powder 15-25 parts, linseed oil 1-4 parts, 1-4 parts, sucrose 3-5 parts of silica nanometer powder.
As further scheme of the invention：Raw material by weight includes：2 parts of hexadecanol, 2 parts of ethylene glycol, 2 parts of glycerine, 2 parts of ethyl acetate, 13 parts of stearic acid, 20 parts of zeolite powder, 2.5 parts of linseed oil, 2.5 parts of silica nanometer powder, 4 parts of sucrose.
Compared with prior art, the beneficial effects of the invention are as follows：Raw material is easy to get, non-volatile, and without dirt evil, processing prepares simple, with low cost, improves fine particle content in cement, improves grinding aid efficiency, reduces production cost, has saved power consumption；Also improve enhancing effect simultaneously.
Specific embodiment
The technical scheme of this patent is described in more detail with reference to specific embodiment.

Embodiment 2
A kind of cement grinding aid, raw material by weight includes：2 parts of hexadecanol, 2 parts of ethylene glycol, 2 parts of glycerine, 2 parts of ethyl acetate, 13 parts of stearic acid, 20 parts of zeolite powder, 2.5 parts of linseed oil, 2.5 parts of silica nanometer powder, 4 parts of sucrose.
The powder grinding aid that pulverizing cement clinker is exclusively used in the present invention uses customary preparation methods, mixes above-mentioned each raw material by formulation ratio, stirs and obtains final product powder grinding aid.
In by 0.45% volume addition clinker, rupture strength improves 3.1MPa within 3 days, and compression strength improves 3.8MP, reaches the effect saved power consumption, improve powder efficient utilization.
Embodiment 3
A kind of cement grinding aid, raw material by weight includes：3 parts of hexadecanol, 3 parts of ethylene glycol, 3 parts of glycerine, 3 parts of ethyl acetate, 15 parts of stearic acid, 25 parts of zeolite powder, 4 parts of linseed oil, 4 parts of silica nanometer powder, 5 parts of sucrose.
The powder grinding aid that pulverizing cement clinker is exclusively used in the present invention uses customary preparation methods, mixes above-mentioned each raw material by formulation ratio, stirs and obtains final product powder grinding aid.
In by 0.50% volume addition clinker, rupture strength improves 3.2MPa within 3 days, and compression strength improves 3.5MP, reaches the effect saved power consumption, improve powder efficient utilization.
The better embodiment to this patent is explained in detail above, but this patent is not limited to above-mentioned implementation method, in the ken that one skilled in the relevant art possesses, can also be made a variety of changes on the premise of this patent objective is not departed from.
