Description
Technical field
The present invention relates to a kind of mineral dispersant and preparation method thereof.
Background technology
The occasions such as grinding distribution of filler all need to use a kind of mineral dispersant in the grinding distribution of the grinding distribution of papermaking filler, porcelain, cement diminishing, water body antiscale, water paint, so that slurry content is high when grinding distribution, stable system, good fluidity, when water treatment, can stablize carbonate in the water body, phosphate, silicate etc. easily scale forming matter be microcrystalline state and be suspended in the water body and do not deposit.
This dispersant relies on acrylate homopolymer for a long time in the performance leading role, and the copolymer of various interpolation trace function monomers also has research report or a small amount of production and sales, but there are in the following problems one or more in they, so that uses limited:
1) is the Molecular regulator amount, uses in a large number sodium hypophosphite or other phosphorus compound; Cause the applied environment eutrophication, easily grow algae, cause environmental pollution.
2) be the Molecular regulator amount, use in a large number the organic solvents such as isopropyl alcohol, such as patent CN92101664, WO2002049765 etc., increased on the one hand energy consumption and complexity; The time spent volatilizing loss of solvent recovery cover is larger on the other hand, and is unfavorable to environment; In addition, the organic matter that remains in the dispersant can enter the downstream application system along with dispersant, produces negative influence.
3) be the Molecular regulator amount, patent CN200610098170 has used mercaptoethanol, and there is the problem of security, stability in mercaptoethanol, so substantially can't promote the use of.
4) active group unreasonable allocation, the not good and afunction of effect.Patent CN20081002010 pointed out once that " best water treatment agent should have strong acid and two kinds of functional groups of weak acid; wherein strong acid functional group is keeping slight ion characteristic (helping dissolving), and the weak acid group then has stronger restriction ability (inhibition crystalline growth) to active site.In addition ,-COOH to the resistance CaCO
3Dirt is effective ,-OH ,-SO
3H is to resistance Ca

4)
2Dirt is useful, only have-COOH ,-OH ,-SO
3H three's synergy just can show best scale inhibition effect, just lacks in the market all very desirable anti-incrustation corrosion inhibitors of this scale inhibition and corrosion mitigating effect." patent CN200610098170, CN200780029577, CN200710013677, CN200910115477,200910039140 mentioned products lack strong acid group and cause afunction; can significantly weaken if be used for phosphatic system dispersion effect, be difficult to avoid phosphate and in fact contain the mineral matter system.
5) commercially available grinding distribution agent also often occur slurry return sticking, slurry system is unstable, free dispersant is too many in the slurry (has side effects on the one hand, reduced on the other hand the product utilization rate) etc. problem, commercially available water treatment dispersant often occur flocculating deposition, the phenomenon of poor effect when disperseing zinc and phosphate radical.
