| titleOfInvention | A kind of amine-methylated lignin-base dispersant and preparation technology and application |
| abstract | The invention discloses a kind of amine-methylated lignin-base dispersant and preparation technology and application, with black liquor of pulp making that solid content is 11.8 ~ 60% as raw material, it is warming up to 20 ~ 80 DEG C, add sulphonic acids amino-compound, regulation pH value is to 10.0 ~ 13.5, it is subsequently adding the aldehyde compound that mass fraction is 1.0 ~ 9.0%, 0.5 ~ 3h is reacted at 60 ~ 110 DEG C, adding mass fraction is the sulfonating agent of 2.5 ~ 15%, 2 ~ 5h is reacted at 95 ~ 180 DEG C, cooling discharge, obtains brown-black liquid, i.e. obtains solid powder by being spray-dried.The amine-methylated lignin-base dispersant that the present invention prepares has the several functions such as dispersion, complexation, chelating, can be used for the multiple fields such as dye dispersant, concrete admixture, ceramic additive. |
