Abstract
The invention relates to a sulphamate-based cement grinding aid, which comprises the following components of: by weight, 40-60 parts of a sulphamate water reducer, 5-10 parts of triethanolamine, 5-20 parts of glycerol, 3-5 parts of sodium acetate, 2-5 parts of sodium hyposulfite and 10-45 parts of water. By the adoption of the sulphamate-based cement grinding aid provided by the invention, the yield of a cement bowl mill is raised by 10-15%, cement early strength is appropriately raised, and cement later strength is increased; or under the condition that the cement strength maintains the same, the cement clinker ratio is reduced by 4-6% and accordingly the mixing amount of cement mixed materials is increased by 4-6%. In addition, the cement production cost is remarkably reduced, and the economic and social benefits of cement enterprises are raised.
Description
Technical field
The present invention relates to a kind of cement grinding aid, belong to the cement additive technical field.
Background technology
Cement grinding aid is to be used to improve cement mill output, reduces the cement grinding power consumption or/and increase cement fineness (grinding aid effect), or/and improve the technology admixture of cement quality (for example: significantly improve strength of cement).Its add-on is no more than 0.5% of cement quality.
The equipment that the cement grinding operation is used mainly is ball mill, and the capacity usage ratio of ball mill is less than 5%.Cause the cement grinding operation to consume a large amount of electric energy, account for 35% of the total power consumption of manufacture of cement; Moreover, as the production of the half-finished cement clinker of manufacture of cement, need to consume a large amount of natural resourcess (raw material, fuel) a large amount of CO of discharging in the production process
2And other can cause the gas and the dust of environmental pollution.Reduce the grog consumption in the manufacture of cement, significant to the energy-saving and emission-reduction of Cement industry.Therefore, the power consumption when how to reduce cement grinding and use cement clinker less is the key subjects of Cement industry.When cement grinding, adding an amount of grinding aid, is to improve mill output, reduce grinding pow consumption, improve the cement quality, many admixtures blended material, uses one of the effective way of cement clinker less.
Existing cement grinding aid kind is more, and patent CN 101898879A discloses a kind of output-increased composite portland cement grinding additive, and weight percent consists of: trolamine 40～65; Terepthaloyl moietie 1.5～6; USP Kosher 1～2; Calcium lignin sulphonate 1.5～6; Zero(ppm) water 25～50.CN101125742A discloses a kind of cement grinding aid, and the weight ratio of each component is: trolamine 10%～30%, tri-isopropanolamine 12%～30%; Terepthaloyl moietie 5%～20%; Ucar 35 3%～10%, water 15%～40%, X 2073 1%～5%; Xylogen 3%～10%, SODIUM SULPHATE ANHYDROUS 99PCT 2%～5%.This cement grinding aid can improve mill efficiency, improves the early stage and later strength of cement, reduces cement cost.But these two kinds of grinding aids have used the alcamines raw material in a large number, and raw materials cost is higher, and cost performance is lower.
Sulfamate is amino-aryl sulfonic acid salt-P-F condenses; Being called for short ASPF, as water reducer of cement concrete, is a kind of resin type high efficiency water reducing agent of non-bleed usually; Belong to no chlorine, low alkali, environmentally friendly machine; Water-reducing rate can reach more than 25%, and slump-loss is little, is fit to high-strength, the super high strength concrete of preparation C50～C100.But the sulfamate volume is prone to cause excessive bleeding and slow setting when higher; Usually with sulfamate and the compound diminishing and the concrete slump retentivity of enhancing preferably of just reaching of naphthalene series high-efficiency water-reducing agent; Therefore this has influenced the actual use of sulfamate, and needing the better approach of research to give full play to sulfamate does not have chlorine, low alkali, environmental protection, advantage that water-reducing property is good.Though sulfamate water reducer is good to the water-reducing effect of cement concrete, can not be used for the additive of pulverizing cement simply, it does not have the visible action effect.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency and a kind of thionamic acid alkali cement grinding aid is provided, this product cost price is low, low alkali, environmental protection, and grinding aid, reinforced effects are good.
A kind of thionamic acid alkali cement grinding aid, its weight part ratio consists of: 40～60 parts of sulfamate water reducers, 5～10 parts of trolamines, 5～20 parts of USP Kosher, 3～5 parts of sodium-acetates, 10～45 parts in 2～5 parts in Sulfothiorine and water.
Described thionamic acid alkali cement grinding aid, its weight part ratio composition is preferably: 50 parts of sulfamate water reducers, 8 parts of trolamines, 15 parts of USP Kosher, 3 parts of sodium-acetates, 20 parts in 4 parts in Sulfothiorine and water.
The preparation method of above-mentioned thionamic acid alkali cement grinding aid proportions each raw material, stirs, and promptly gets.
Cement grinding aid of the present invention adds in the grinding machine with each constituent materials when pulverizing cement, and add-on is 0.04%～0.08% of a cement quality.
The invention has the beneficial effects as follows: thionamic acid alkali cement grinding aid of the present invention has and improves cement ball mill output 10%～15%, suitably improves cement early strength and increase the effect of cement later strength; Or keeping reducing by 4～6 percentage points of cement clinker proportionings, 4～6 percentage points of corresponding increase cement mixture addition contents under the identical condition of strength of cement.Significantly reduce the manufacture of cement cost, improved the economic benefit and the social benefit of cement production enterprise.
Thionamic acid alkali cement grinding aid of the present invention, raw material is inexpensive, and the preparation method is simply easy, and the product cost price is low, and grinding aid, reinforced effects are good.
