Abstract
The invention discloses a cement grinding additive. The cement grinding additive comprises the following components in parts by weight: 10-25 parts of anhydrous sodium sulphate, 2-5 parts of polymeric alkylol amine, 1-3 parts of calcium formate, 0.5-2.3 parts of aluminum sulfate, 8-12 parts of ethylparaben, 5-10 parts of waste sugar residue, 2-6 parts of pulverized fuel ash, 2-8 parts of polyethylene glycol, 1-4 parts of an initiator and 20-30 parts of water. The cement grinding additive is high in stability and low in cost, and can be used for effectively increasing the utilization rate of the energy in the cement grinding process.
Description
Technical field
The present invention relates to building material technical field, be specifically related to a kind of cement grinding aid.
Background technology
Cement abrasive dust, as the highest process procedure of energy consumption in cement production process, in milling process, often causes cement grinding efficiency to decline, degradation problem under mill efficiency.Generally need to add cement grinding aid to improve grinding grinding situation.But conventional cement grinding aid to there is manufacturing cost high, the problems such as demand is large.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of cement grinding aid, and it is high that this grinding aid solves existing grinding aid cost, the problem that demand is large.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of cement grinding aid, comprises the component of following weight part, Sodium sulfate anhydrous.min(99) 10-25 part, polyalcohol amine 2-5 part, calcium formiate 1-3 part, Tai-Ace S 150 0.5-2.3 part, ethyl p-hydroxybenzoate 8-12 part, useless sugared slag 5-10 part, flyash 2-6 part, polyoxyethylene glycol 2-8 part, initiator 1-4 part, water 20-30 part.
Further, a kind of cement grinding aid, comprises the component of following weight part, Sodium sulfate anhydrous.min(99) 15 parts, polyalcohol amine 3 parts, calcium formiate 2 parts, 1.5 parts, Tai-Ace S 150, ethyl p-hydroxybenzoate 9 parts, useless sugared slag 7 parts, 4 parts, flyash, polyoxyethylene glycol 6 parts, initiator 3 parts, 25 parts, water.
Further, described initiator is Benzoyl Peroxide.
The invention has the beneficial effects as follows: this cement grinding aid good stability, and cost is low, effectively improves the utilization ratio of energy in cement milling process.
