Abstract
The invention discloses a novel grinding enhancer for cement and a preparation thereof. The grinding enhancer comprises the following components in parts by weight: 7-25 parts of triethanolamine, 4-12 parts of diethanolisopropanolamine, 10-40 parts of polymeric polylol, 7-20 parts of molasses, 5-12 parts of industrial salt, and 20-60 parts of water. The invention further provides a preparation method for the grinding enhancer for the cement; 20-60 weight parts of water is added into a reaction container; 5-12 parts of industrial salt is then added; the mixture is mixed until the industrial salt is fully dissolved; 10-40 weight parts of polymeric polylol, 7-20 weight parts of molasses,4-12 weight parts of diethanolisopropanolamine, and 7-25 weight parts of triethanolamine are sequentially added; the mixture is mixed at 50 DEG C for 1h to obtain the end product. The novel grinding enhancer has a reasonable mixture ratio, and can increase the output of the grinding per machine per hour by 25%, increase the cement intensity, reduce consumption of clinker, reduce energy and consumption, and lower the comprehensive cost of the cement.
Description
Technical field
The present invention relates to a kind of cement industry admixture technical field, relate to specifically a kind of novel liquid grinding aid of cement and its preparation method and application.
Background technology
In cement production process, in order to improve mill efficiency, reduce grinding energy.Adding cement grinding aid is in order to improve the grindability of material, alleviates the adhesive aggregation unity effect between particle, eliminate the subparticle ball and stick with paste the liner plate phenomenon, thereby in the raising grinding machine, the mobility of material realizes the ball grinder saving energy high yield.Therefore, use cement grinding aid to there is larger economic and social benefit and good development prospect.As a kind of cement additire, can improve the size distribution of cement and promote the aquation of cement, thereby improve the mechanical property in each length of time of cement.
Summary of the invention
The invention provides a kind of reasonable ratio, manufacture craft is simple, and grinding aid and reinforced effects are remarkable, the liquid water cement grinding reinforcing agent good with the concrete admixture consistency.
The novel liquid cement grinding aid reinforcing agent that the present invention proposes is comprised of trolamine, di-alcohol monoisopropanolamine, polymerized polyalcohol, molasses, Industrial Salt and water.
Each massfraction formed is
Trolamine 7 ~ 25
Di-alcohol monoisopropanolamine 4 ~ 12
Polymerized polyalcohol 10 ~ 40
Molasses 7 ~ 20
Industrial Salt 5 ~ 12
Water 20 ~ 60
The present invention adopts the following methods preparation.
The water that adds 20 ~ 60 massfractions, and then add 5 ~ 12 Industrial Salt, starting to be stirred to Industrial Salt all dissolves, then add successively molasses, 4 ~ 12 massfraction di-alcohol monoisopropanolamines of polymerized polyalcohol, 7 ~ 20 massfractions of 10 ~ 40 massfractions, the trolamine of 7 ~ 25 massfractions, stir 1h under 50 ℃, get product.
Beneficial effect of the present invention and characteristics.
1, the polymerized polyalcohol that in component of the present invention, unique oiling massfraction is 10 ~ 40, can improve mill efficiency effectively, the highlyest improves 30%.
2, but the present invention is liquid grinding aid long-term storage under differing temps, without layering and precipitating.
3, grinding aid of the present invention has wide range of applications, and can be used for the cement of the different compounds of admixture.
4, after application the present invention, cement 3 days and 28 days intensity all can improve 20% ~ 30%, simultaneously can effectively improve the cement granules grating, same specific surface area, cement fineness 4 ~ 6%(80 μ m sieve that can descend).
5, volume is few compared with similar products, and admixture 0.03% just can play obvious effect, reduces costs.
