Description
Technical field
The present invention relates to construction material preparation technical fields, and in particular to a kind of concrete high stability water-reducing agent.
Background technique
Retardation water reducing agent is a kind of additive being of wide application in concrete admixture, has both slow setting and reduces mix
The characteristic of water consumption, and high performance retardation water reducing agent has stronger peptizaiton to cement, can keep coagulation well
The slump of soil.
Since general polycarboxylate water-reducer influences not being very greatly, to want in setting time on the setting time of concrete
The method of compounding retarder is generallyd use when asking longer.But in actual application, to the biggish retarder of dosage is equal
Even compounding into water-reducing agent be it is relatively difficult, need being stirred for long period, seriously affect the compounding efficiency of water-reducing agent;
And when the polycarboxylate water-reducer time of repose for having compounded more retarder is slightly long, it may appear that contained slow setting in upper and lower level water-reducing agent
The very big problem of constituent content difference, to influence the service performance stability of concrete obtained by mix.
Summary of the invention:
Technical problem to be solved by the present invention lies in providing, a kind of formula is reasonable, simple production process, and performance is stable
Concrete high stability water-reducing agent.
The technical problems to be solved by the invention are realized using following technical scheme:
A kind of concrete high stability water-reducing agent, which is characterized in that be prepared from the following raw materials in parts by weight: polyethylene glycol
20-30 parts of monomethyl ether, 10-15 parts of adsorbent, 5-10 parts of xanthan gum, 2-8 parts of beta-cyclodextrin, is handed over 20-30 parts of lignosulfonates
Join povidone 1-5 parts, 2-5 parts of polyethyleneglycol diacrylate, 2-6 parts of ascorbic acid, 1.5-3 parts of iron chloride, potassium peroxydisulfate 2-5
Part, 0.2-2 parts of lauryl sodium sulfate.
The adsorbent is made of zeolite powder, active powdered carbon, rice straw, alum according to mass ratio 1:1:1.5:0.5,
Production method are as follows: rice straw is placed in 120-150 DEG C of drying box and is dried to moisture content no more than 2%, be ground into 40-60 mesh
Powder is added suitable quantity of water and is evenly stirred until cement paste, be then placed in 400-600 DEG C of retort and be carbonized 1-3 hours, takes out cold
But it is ground into 60-80 mesh powder afterwards, obtains carbonized powder;Alum is dissolved in suitable quantity of water, is concentrated under reduced pressure, then after being dried
80-100 mesh powder is pulverized into, alum powder cleaning is obtained;The carbonized powder and alum powder cleaning are mixed, are added
Zeolite powder and active powdered carbon and pure water are ground 2-3 hours, are finally spray-dried to obtain the final product.
The concrete high stability water-reducing agent, the production method is as follows:
(1) poly glycol monomethyl ether, lignosulfonates are mixed, add water until being completely dissolved, is heated to reflux state,
Xanthan gum is added, stirs evenly, continues heating 5-10 minutes, adds beta-cyclodextrin, is then heated to reflux state heat preservation and stirs
It mixes 3-5 hours, obtains material I;
(2) adsorbent, polyethyleneglycol diacrylate are mixed, is heated to 115-125 DEG C of insulated and stirred 5-10 minutes, then
Crospovidone is added and continues insulated and stirred 5-10 parts, adds iron chloride, continues stirring 5-10 minutes, obtains material II;
(3) material I, material II are mixed, carries out heating grinding 10-20 minutes, potassium peroxydisulfate is added, continue heating grinding
10-20 minutes, ascorbic acid, lauryl sodium sulfate are continuously added, continues heating grinding 10-15 minutes, obtains material III;
(4) material III is put into frequency 20KHZ, carries out ultrasonication 5-15 in the processor for ultrasonic wave of power 900W
Minute, then vacuum compression is blocking, is transferred to sealing and standing 3-5h in -10 DEG C of environment, micro mist most is made through micronizer afterwards, i.e.,
Obtain concrete high stability water-reducing agent.
The beneficial effects of the present invention are:
1, present invention process process is succinct, reasonable raw material proportioning, and use is nontoxic chemical substance production, former
To expect cheap, the cement water reducing agent of preparation, water-reducing effect is good, and applicable performance is strong, and using effect is obvious, and market value is high,
Convenient for promoting and using;
2, the present invention is using poly glycol monomethyl ether and lignosulfonates as primary raw material, then cooperates adsorbent, enhances
Water imbibition, while joined xanthan gum, beta-cyclodextrin, the comixing compatibility of different water-reducing agent ingredients is increased, viscosity is glued;This hair
It is bright to also added crospovidone, polyethyleneglycol diacrylate, ascorbic acid, improve the compatible dispersion of each ingredient of water-reducing agent
Property and stability, can be good at being scattered in cement when reapplying water-reducing agent, reinforce using effect.
