dispersant also by is wet lubricating dispersant, it main/primary to lubricating wet function, remove tool has wet made function outer, its active property 基团一端 can in powder formed fine small micro 粒 颜 material surface, 另一端 solvent agent 化进入漆基形 formed 吸附层, generate electrical force or force, make material pellets long dispersion 悬浮于漆基 in, again 次絮凝, ensure made formed color system stability, can 说一 良 good material dispersion system 离不开 lubricating wet dispersant 辅助. currently material in commonly used dispersant has very multiple, its structure separation, main/primary can separation is below/following types type type.

non type lubricating wet dispersant in water in belt/tape electrical 荷, therefore in material surface relatively low, it main/primary separation is ethylene glycol type and more alcohol type types non type lubricating wet dispersant, it can and anionic type dispersant combined make used as is wetting agent or emulsification agent, therefore 广泛 应 used for water property color 浆, water property coating material and ink in, can reduce coating material surface force and improve/increase lubricating wet property and other.

两 property type lubricating wet dispersant is anionic and cationic 离子 组 formed types combined material, used for acid ester salt type polymer/macromolecule polymer, this category of polymer acid value relatively high, can can effect/influence between force.

electrical in property type lubricating wet dispersant in in anionic and cationic has machine large small basic versus and other, therefore, although separation 子呈现 in property, tool has 一定 极 property.

polymer/macromolecule non type dispersant is types commonly used dispersant, it stability property non good. polymer/macromolecule type dispersant separation is more inner more ester more alcohol - more ethylene amine copolymer type dispersant, acrylic ester polymer/macromolecule type dispersant, polyurethane ester, polymer/macromolecule polyether and polyester type polymer/macromolecule dispersant and other, due to it 们 锚定基团一头 and material pellets 包附, 另一头 also and resin 缠绕吸附, therefore stability property relatively good.

anionic type lubricating wet dispersant is lubricating wet dispersant in types, it large separation is non property belt/tape negative electrical hydrophilic carbon hydrogen separation and property hydrophilic water 基团构 formed, this types separation in separation 子 两端, therefore, formed for hydrophilic water hydrophilic separation structure, meanwhile anionic type lubricating wet dispersant versus property very good, more by used for water property coating material and ink in, can used for solvent agent type coating material as is 受控絮凝 type dispersant use, it main/primary product types has: acid 钠, acid salt, acid ester salt, acid salt and other.

cationic type lubricating wet dispersant is types non property belt/tape positive electrical 荷 化 combined material, main/primary product types has amine salt, amine salt, 吡啶鎓 salt and other. cationic surface active property agent force relatively strong/high, for 炭黑, various oxidation iron, has machine material type and other material dispersion relatively good, need it and material in 羧基起 chemical reaction, meanwhile also need attention/notes need and anionic dispersant meanwhile use.

受控自由基 type ultra- dispersant using/adopting most new free radical polymerization technology, can make dispersant structure more add 规整. commonly used methods has: 原子转移 free radical polymerization, can add formed fracture 链转移 can free radical polymerization, stability free radical polymerization and other, through using/adopting free radical polymerization technology, can make dispersant versus for separation quality distribution more is in, 锚定基团也 more is in, improve/increase production efficiency. 受控自由基 type ultra- dispersant chemical dispersant property 广, 广泛 应 used for nano general purpose color and other industry.
