Wetting agent

Wetting agents available on the market such as jfc, jfcs, Periga series, el series and aeo series, penetrant t, etc., are surfactants and textile wetting agents. Textile wetting agents are fatty carbon chains as hydrophobic base, and the chemical structure of the dye (pigment) aromatic hydrocarbons have no similarity, low affinity, and the combination is not firm. Therefore, the hydrophobic application of the wetting agent for dyes (pigments) is an aromatic hydrocarbon, which binds the dye (pigment) particles in a strong anchoring manner, and does not fall off the surface of the particles during long-term placement, and the hydrophilic group stretches in the water to provide steric or electric repulsion.

The wetting agent whose hydrophobic group is aromatic hydrocarbon has different bonding degree with dye (pigment) particles. The comparison between tx-10 and solsperse27000 is taken as an example.

tx-10,s-27000 and emulsifier 600 sulfate were esterified to obtain two hydrophilic groups in one molecule.

In addition to sulfuric acid esterification, carboxylic acid esterification is also available, which has good compatibility with many commonly used organic pigment carboxylic acid polymer dispersants.

In order to improve the affinity with the hydrophobic part of organic pigments, Xu Yanli et al., Beijing University of Chemical Technology, studied tmeen20 carboxylate as a water-based decomposition agent to modify the surface of phthalocyanine blue.

The critical surface tension σc(σsc) increased from 23mn/m to 34.8mn/m by 351% when 0.5%~3.0% of the above additives were added to phthalocyanine blue. The contact Angle to water is reduced from 82.4 to 47, a decrease of 347%. Therefore, the wettability of phthalocyanine blue in water is greatly improved, the fluidity after treatment is increased by 2.5 times, and the dispersion stability in water is increased by 29%.

The non-ionic surfactant is carboxylated to obtain the corresponding product, which can be used as a surfactant for wetting and dispersing dyes (pigments).

dispersant

Lignosulfonic acid is the most effective dispersant. Lignosulfonate is an anionic surfactant consisting of a plurality of 4-carboxyl-3-methoxypropane hydroxyl and sulfonic acid based polymerization of plies, with an average molecular weight of 8000~13000, sulfonate is generally sodium salt, calcium salt, but also ammonium salt, is a polymer electrolyte.

The use of ammonium lignosulfonate is more effective than other sulfonates in improving the solubility of dyes. However, ammonium lignosulfonate has not been mass-produced in China. Some suggest using borregard's borresperseam-320; reed's lignosol tsf, lignosol tsd, lignosol TSF-65, and lignosol sfx-65.
