Abstract
The invention belongs to a cement auxiliary and particularly relates to a cement grinding aid and a using method thereof. The cement grinding aid is prepared from the following components in parts by weight: 0.5-5 parts of modified cellulose, 1-5 parts of polyether polyol, 2-10 parts of hydramine substances, 1-9 parts of an enhancer, 2-10 parts of polyhydric alcohol, 0.1-1 part of urea and 14-45 parts of water. The grinding aid for a cement processing process provided by the invention plays a role of adjusting the particle sizes of cement, enhances the cement strength and reduces the energy consumption in the cement production process.
Description
Technical field
The invention belongs to cement adjuvant, be specifically related to a kind of cement grinding aid, also relate to its using method.
Background technology
In the ball milling operation of producing cement, after cement granules particle diameter is reduced to micron order, quality is in uniform state, intensity and hardness to be increased, and causes grindability to worsen.As everyone knows, cement granules particle diameter is 3 ~ 32
μmin time, contributes comparatively greatly strength of cement, and cement granules particle diameter is 3 ~ 32
μmmore, strength of cement is larger.Meanwhile, because specific surface area and surface energy enlarge markedly in cement process, the mutual conglomeration aggregation tendency of subparticle obviously strengthens, if do not take certain measure, crush efficiency will be caused to decline, and per unit area yield power consumption will obviously raise.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of cement grinding aid, reduces the energy consumption in cement production process, regulates cement granules particle diameter, refinforced cement intensity simultaneously, reduces cement clinker consumption.
Technical problem to be solved by this invention is achieved by the following technical programs:
A kind of cement grinding aid, is made up of the component of following parts by weight:
Modified-cellulose 0.5 ~ 5 part;
Polyether glycol 1 ~ 5 part;
Alcamines material 2 ~ 10 parts;
Toughener 1 ~ 9 part;
Polyvalent alcohol 2 ~ 10 parts;
0.1 ~ 1 part, urea;
14 ~ 45 parts, water.
Described modified-cellulose is at least one in carboxymethyl propyl cellulose, Vltra tears, hydroxyethylmethyl-cellulose.Through the Mierocrystalline cellulose good water solubility of modification, there is-OH, the active site of maskable cement granules section, stop cement granules polymerization, also there is-CH
3can prevent cement granules from reuniting, for cement granules grinding, there is better effects.
Described polyether glycol is oxyethane and epoxy propane copolymer, molecular weight ranges 150 ~ 500, and oxyethane weight ratio accounts for 30 ~ 60%.-the OH of this kind of polyether glycol and-CH
3regulate by polymerization ratio, and modified-cellulose can act synergistically, regulate cement granules particle diameter, cement size controlling is being contributed within maximum scope strength of cement.
Described alcamines material is Triethanolamine 99(TEA 99), tri-isopropanolamine, at least one in trolamine, α-amino isopropyl alcohol.
Described toughener is calcium formiate, at least one in calcium chloride, nitrocalcite.
Described polyvalent alcohol is ethylene glycol, propylene glycol, glycerol, sorbyl alcohol, 1,3-butyleneglycol, at least one in Xylitol.
A using method for above-mentioned cement grinding aid, be in cement, add described cement grinding aid, addition accounts for 0.15 ~ 3% of cement gross weight.The present invention has following beneficial effect:
Energy consumption in energy cement production process can fall in cement grinding aid of the present invention, regulate cement granules particle diameter simultaneously, refinforced cement intensity, improves water-repellancy, the processibility of cement series product, reduces the dust pollution in cement clinker consumption and cement production process.
Embodiment
Below in conjunction with embodiment, the present invention will be described in detail, and embodiment is only the preferred embodiment of the present invention, is not limitation of the invention, and table one is the specific embodiment 1,2,3 of cement grinding aid of the present invention.
Table one
The preparation method of above-described embodiment is approach well known, does not describe in detail at this.
Added in cement by the cement grinding aid that embodiment 1,2,3 obtains and carry out performance test, the addition of grinding aid is 0.2%, and the concrete composition of concrete experiment parameter and cement is in table two
table two
The cement size distribution table three that experiment 1-4 obtains
table three
As can be seen from table two and table three, add the cement particle diameter of cement grinding aid 3 ~ 32
μmmaximum, strength of cement is the highest, adds grinding aid strength of cement and is all better than the cement not adding cement grinding aid.The particle diameter wherein testing 4 cement is best, and strength of cement is the highest.
