Abstract
The invention discloses an azo pigment acid coupling reaction auxiliary and application thereof. The azo pigment acid coupling reaction auxiliary comprises, by weight, 30-50% of polyoxyethylene ether surfactant, 20-30% of dispersant, 20-30% of thiourea and 5-15% of water. The azo pigment acid coupling reaction auxiliary is mainly composed of the surfactant, the dispersant and the thiourea, coupling components and generated pigment particles can be fully wetted, the grinding efficacy can be improved, and thus the reaction speed and the product yield can be improved.
Description
Technical field
The present invention relates to a kind of reaction promoter, relate in particular to a kind of azo pigment even reaction promoter of acid and application thereof.
Background technology
Pigment dyestuff is applied with dispersion state, keeps its crystal or particle structure state in coloring process.Different with heterocyclic pigment from phthalocyanines, azo pigment is wished to get good dispersion state, must be from synthetic.In building-up process, first forming water-fast nucleus, then grow into crystal, is primary particle.Primary particle is easily assembled for offspring, and particle diameter increases to 0.5～10 μ m from 0.1～0.5 μ m.So some physical properties of pigment, for example crystal configuration, crystallographic dimension, crystal mass, and size of particles and distribution, all must be in synthetic and pigmenting process, by regulating reaction parameter (pH value, temperature, concentration and stirring velocity etc.), and add tensio-active agent to be controlled, to meet application quality requirement.
Do not add different tensio-active agents by the stage, role difference what react.Before dissolving, diazo component adds tensio-active agent, its dissolving of mainly useful for, for example dissolving of CLT phenol.After diazotization reaction finishes, add tensio-active agent, be conducive to decolouring.Before dissolving, coupling component add tensio-active agent to contribute to the dissolving of powdery coupling component.Added tensio-active agent is all wetting agent above.In coupling process, add tensio-active agent to be conducive to generate the pigment of primary particle, slow down it and further assemble, to obtain more transparent and higher tinting strength.Before pigment thermal treatment, add tensio-active agent, can avoid pigment further to assemble and cause tinting strength to decline.Above added tensio-active agent is all dispersion agent.
Surface of pigments modification can be improved many physical propertiess, as granular size, size distribution, surface property, specific surface area and crystal formation etc., improve thus the application performance of pigment, as coloured light, tinctorial strength, vividness, transparency or opacifying property, dispersiveness and mobility etc.Reach above requirement, need add special surface modification auxiliary agent.
Show according to published data, adjuvant used in the synthetic and pigmenting process of existing pigment have alizarin assistant (Viscotrol C sulfuric ester sodium salt), penetrant t (disecoctylmaleate sodium sulfonate), Igepon T (18 oleylamide-N-methyl-ethylene sulfonate sodium), Nekal BX (diisobutyl sodium naphthalene sulfonate), Emulphor FM (triethanolamine monostearate), dispersion agent NNO, rosined soap, non-ionic type polyoxyethylene ether surface active agent, an anion surfactant etc.Existing pigment additive synthesis is independent use mostly, and often effect is not good enough.
