A cement disperser in the form of liquid for increasing the pulverization effect in ball grinding, cement output greatly, and cement quality by 100 numbers is prepared from sulfuric acid, sodium hydroxide, sodium sulfate, refined naphthalene, triethanolamine, urea, calcium nitrate, formaldehyde, calcium lignosulfonate, sodium dodecylbenzenesulfonate, soap base and epoxy ethane through sulfonation reaction of part of raw materials, preparing non-ionic surfactant and cationic surfactant and mixing. Its preparation has no environmental pollution.
Description
The present invention be a kind of in cement production process, dose in order to cement liquid dispersion agent of improving cement output and preparation method thereof.
Existing cement dispersants all is pulverous, aborning cement and dispersion agent is mixed in proportion, and makes the ball mill workload strengthen for mixing, though can improve cement output, the dispersion dosage that adds is also many.
The objective of the invention is to, a kind of cement liquid dispersion agent that can increase substantially manufacture of cement amount and cement quality and preparation method thereof is provided.
The present invention can realize with following mode:
The proportioning raw materials of cement dispersants is sulfuric acid 20-60, sodium hydroxide 10-30, sodium sulfate 40-80, refined naphthalene 5-15, trolamine 80-100, urea 40-60, nitrocalcite 50-90, formaldehyde 30-60 calcium lignin sulphonate 120-160, Sodium dodecylbenzene sulfonate 3-15, soap base 6-30, oxyethane 280-320.
The preparation method of described cement dispersants, the first step prepares beta-naphthalenesulfonic-acid formaldehyde condensation compound, and step is as follows, take by weighing 128 gram naphthalenes addings, 128 gram sulfuric acid sulfonation under 160-163 ℃ of condition and reach 2--3 hour, be cooled to then about 120 ℃, add water 250ml, stir, continue to be cooled to 90 ℃, add sulfuric acid 35 grams, add formaldehyde 80ml, divide for several times to drip, controlled temperature is at 85-90 ℃, carry out condensation and reach 2-3 hour, with alkali neutralization, filter dry beta-naphthalenesulfonic-acid formaldehyde condensation compound then again.Oxyethane 280-320 gram is got in the second step nonionogenic tenside preparation, under the trolamine katalysis, under 150-160 ℃ of condition polymerization 2-3 hour, product.The cats product preparation of the 3rd step.Get trolamine 80-100 gram, with sulfuric acid 5-7 gram react product, the 4th step emulsifying agent preparation: in the ratio of 3-15 gram Sodium dodecylbenzene sulfonate and 6-30 gram soap base, Hybrid Heating under 100 ℃ condition, being clear solution is products therefrom, the 5th step mixed, and got beta-naphthalenesulfonic-acid formaldehyde condensation compound 8.5-27.5 gram, calcium lignin sulphonate 6-8 gram, urea 4-6 gram, thorough mixing stirs, and adds second one and the 3rd product that goes on foot then, stirs about 10 hours, add nitrocalcite 6-9 gram again, after continuing to be stirred to dissolving fully, add 4-8 gram sodium sulfate again and stir, dissolving, leave standstill, promptly get the cement dispersants finished product.
The present invention can improve cement output 30% (1 ton of cement adds 300-350 gram dispersion agent), improve cement quality, label improves No. 100, and this dispersion agent is a liquid, when carrying, grog at the uniform velocity in material, drips, grog disperses rapidly, prolongs ball mill work-ing life, cuts down the consumption of energy, reduce production costs, this dispersion agent also can improve concrete every performance, produce this dispersion agent to environment without any pollution, to the person without any injury.
