Abstract
The invention discloses a kind of collapse protection type water reducer, it is mixed by the raw material of following weight part: methyl naphthalene sulfonic acid salt formaldehyde condensation products 48-62, polycyclic aromatic hydrocarbon sulfonate formaldehyde condensation products 24-36, glycerin polyoxyethylene ether ethylhexoate 16-28, porous calcium phosphate 15-20, rock wool powder 10-15, sodium polystyrene sulfonate 5-10, aloe powder 5-10, squalane 4.5-6.5, diisobutyl carbinol(DIBC) 3-5, algin oligosaccharide 2-4, hyaluronate sodium 2.5-4.5, sand amasss stone flour 6-12, volcanic ash 10-15, lauric acid diethyl amide 3-6, hydroxypropyl guar rubber powder 4-8, auxiliary agent 3-6.Collapse protection type water reducer slump retaining of the present invention is excellent, little loss of slump, and water-reducing rate is high, avoid segregation or bleeding, obvious to concrete reinforced effects, good to concrete adaptability, especially under summer high temperature environment and centering, low flow concrete there is good adaptability.
Description
Technical field
The present invention relates to a kind of collapse protection type water reducer, belong to concrete admixture field.
Background technology
Concrete admixture, is called for short admixture, refers to before mixing concrete mixing or mixes to improve the material of concrete performance in mix process.Because admixture can improve concrete performance effectively, and have good economic benefit, be all widely used in many countries, the application in engineering more and more comes into one's own, and becomes material indispensable in concrete.Wherein collapse protection type water reducer is the one in concrete admixture, and it can keep concrete slump not immediate loss, reaches the effect keeping the slump.Still there is the defect of slump retention time long and high temperature failure in collapse protection type water reducer used in the market, and water-reducing property is poor, cannot meet the construction requirement of high performance concrete.
Summary of the invention
The object of the invention is to solve the defect existed in prior art, a kind of collapse protection type water reducer with very strong slump save power, higher water-reducing rate and good thermotolerance is provided.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of collapse protection type water reducer, is mixed by the raw material of following weight part: methyl naphthalene sulfonic acid salt formaldehyde condensation products 48-62, polycyclic aromatic hydrocarbon sulfonate formaldehyde condensation products 24-36, glycerin polyoxyethylene ether ethylhexoate 16-28, porous calcium phosphate 15-20, rock wool powder 10-15, sodium polystyrene sulfonate 5-10, aloe powder 5-10, squalane 4.5-6.5, diisobutyl carbinol(DIBC) 3-5, algin oligosaccharide 2-4, hyaluronate sodium 2.5-4.5, sand amass stone flour 6-12, volcanic ash 10-15, lauric acid diethyl amide 3-6, hydroxypropyl guar rubber powder 4-8, auxiliary agent 3-6;
The preparation method of described auxiliary agent is as follows: a, get the raw material of following weight part: activated magnesia 5-10, tuff micro mist 10-15, desulphurize fly ash 9-16, melamine urea-formaldehyde resin 12-18, microporous calcium silicate 6-12, polyisobutene 5-10, tertiary ethylene carbonate 4-6,2-methyl-2,4-pentanediol polyoxyethylene polyoxypropylene ether 2-4, sodium pentachlorophenol 1.5-2.5, Coconut Fatty Acid Monoethanolamide 3-5, bone meal 4-8, Poly Dimethyl Diallyl Ammonium Chloride 2-4, sulfonated phenylethylene-maleic anhydride copolymer 5-10; B, by sulfonated phenylethylene-maleic anhydride copolymer, Poly Dimethyl Diallyl Ammonium Chloride, 2-methyl-2,4-pentanediol polyoxyethylene polyoxypropylene ether mixes, then activated magnesia, tuff micro mist, desulphurize fly ash is added successively, 10-15min is stirred under 45-55 DEG C of bath temperature, be cooled to normal temperature, dry, obtain compound A; C, bone meal, microporous calcium silicate to be mixed, then add melamine urea-formaldehyde resin, Coconut Fatty Acid Monoethanolamide, polyisobutene, tertiary ethylene carbonate, sodium pentachlorophenol successively, high speed dispersion 5-10min, dry, obtain compound B; D, compound A and compound B to be mixed, obtain described auxiliary agent.
Beneficial effect of the present invention:
Collapse protection type water reducer slump retaining of the present invention is excellent, little loss of slump, and water-reducing rate is high, avoid segregation or bleeding, obvious to concrete reinforced effects, good to concrete adaptability, especially under summer high temperature environment and centering, low flow concrete there is good adaptability.
