Abstract
The invention discloses a kind of retardation setting type cement grinding aids, are prepared from the following raw materials in parts by weight：20 25 parts of triethanolamine, 10 15 parts of triisopropanolamine, 8~10 parts of sodium tripolyphosphate, 23 parts of calcium formate, 28 parts of molasses, 2~6 parts of alkyl glycosides, 1~6 part of zinc stearate, 12 parts of sulfosuccinate, 35~55 parts of water, 57 parts of chlorohydrocarbon, 5 20 parts of lignin derivative, 20 parts of polyether polyol, the efficiency that the synergistic effect of each component reaches grinding process is optimized and is combined together to the modification of cement granules, the quality and performance that cement is improved while improving cement output, saving power consumption is reached, rather than just a kind of grind -aiding effect.Make to dramatically increase grain size (30 μm or less) particle that strength of cement plays a major role, 10 μm of particles below that water requirement plays a major role are basically unchanged, cement is kept to have higher mobility and lower water requirement.
Description
Technical field
The present invention relates to cement additive technical field more particularly to a kind of retardation setting type cement grinding aids.
Background technology
Currently, cement grinding is necessary process and key link in manufacture of cement, energy consumption and power consumption account for manufacture of cement
70% or more 30% and the total power consumption of total energy consumption, currently, national low-carbon environment-friendly requirement is higher and higher, cement price is dispirited, former material
Material and energy prices appreciate, and industry competition is white-hot, and the benefit of cement production enterprise is made to have too many difficulties to cope with.So energy-saving and emission-reduction, development is low
Carbon economy reduces cost, improves grinding aid performance, is that cement industry compels highly necessary to solve the problems, such as.To reduce energy consumption, grinding is improved
Efficiency, China show grinding aid in use there are still many problems, and the durability such as villaumite to cement and concrete is brought
Prodigious security risk；Grinding aid unstable quality, volume is big, so as to cause cement quality fluctuation etc..In the prior art, cement
Using the outstanding feature of triethanolamine it is that can improve 1 day cement mortar strength of cement in grinding aid, but for 28 days and later intensity
Do not contribute；Triethanolamine is also selected to enhance 7 days of cement, 28 days or later intensity, but three in many cement grinding aids
Ethanol amine cannot increase the early strength within 1 day or 7 days of cement.
Invention content
In consideration of it, the present invention provides a kind of retardation setting type cement grinding aid, it is prepared from the following raw materials in parts by weight：Three second
20-25 parts of hydramine, 10-15 parts of triisopropanolamine, 8~10 parts of sodium tripolyphosphate, 2-3 parts of calcium formate, 2-8 parts of molasses, alkyl sugar
2~6 parts of glycosides, 1~6 part of zinc stearate, 1-2 parts of sulfosuccinate, 35~55 parts of water, 5-7 parts of chlorohydrocarbon, lignin derive
5-20 parts of object, 20 parts of polyether polyol.
The present invention is further described, the calcium formate solution is the calcium formate water solution that mass concentration is 45%.
Using above-mentioned technical proposal, have the advantages that：
The efficiency that the synergistic effect of each component reaches grinding process is optimized and is combined together to the modification of cement granules, makes it
Reach the quality and performance that cement is improved while improving cement output, saving power consumption, rather than just a kind of grind -aiding effect.
Make to dramatically increase grain size (30 μm or less) particle that strength of cement plays a major role, reduced coarse granule (60 μm of ＞), to needing
10 μm of particles below that water plays a major role are basically unchanged, and cement is kept to have higher mobility and lower water requirement.
Specific implementation mode
A kind of retardation setting type cement grinding aid, is prepared from the following raw materials in parts by weight：20-25 parts of triethanolamine, three isopropyls
10-15 parts of hydramine, 8~10 parts of sodium tripolyphosphate, 2-3 parts of calcium formate, 2-8 parts of molasses, 2~6 parts of alkyl glycosides, zinc stearate 1
~6 parts, 1-2 parts of sulfosuccinate, 35~55 parts of water, 5-7 parts of chlorohydrocarbon, 5-20 parts of lignin derivative, polyether polyol
20 parts.
The present invention is further described, the calcium formate solution is the calcium formate water solution that mass concentration is 45%.
The efficiency that the synergistic effect of each component reaches grinding process is optimized and is combined together to the modification of cement granules,
The quality and performance that cement is improved while improving cement output, saving power consumption are reached, rather than just a kind of grinding aid
Effect.Make to dramatically increase grain size (30 μm or less) particle that strength of cement plays a major role, reduced coarse granule (60 μm of ＞),
10 μm of particles below that water requirement plays a major role are basically unchanged, cement is kept to have higher mobility and lower need water
Amount.
The foregoing describe the basic principles and main features of the present invention, It should be understood by those skilled in the art that of the invention
It is not restricted to the described embodiments, the above embodiments and description only illustrate the principle of the present invention, is not departing from
Under the premise of spirit and scope of the invention, various changes and improvements may be made to the invention, these changes and improvements both fall within requirement
In the scope of the invention of protection, invents claimed range and be defined by the appending claims and its equivalent thereof.
