Dispersant
In emulsion paint, dispersant is generally divided into two big classes: inorganic dispersant and organic dispersing agent.In inorganic dispersant
Most is polyphosphoric acid salt, such as sodium hexameta phosphate, PTPP (potassium tripolyphosphate), sodium polyphosphate and tetrapotassium pyrophosphate.The machine of its effect
Reason is by hydrogen bond and chemisorbed, plays electrostatic repulsion Stabilization.Organic dispersing agent includes that polyacrylate is (the most poly-
Ammonium acrylate salt), polystyrene/maleic acid salt, polyisobutylene/maleic acid salt etc..Their feature is,
Producing strong absorption or anchorage effect at pigment and filling surface, have longer strand sterically hindered to be formed, the end of the chain has
Water solublity, have the most auxiliary has electrostatic repulsion, reaches stable result.Dispersant to be made has good dispersion effect and is necessary for sternly
Lattice control molecular weight size, molecular weight is the least, sterically hindered not, molecular weight too conference produce flocculation.

Thickening agent
Coating thickener kind is a lot, mainly have cellulose family, polyacrylate-type thickeners, polyurethanes thickening agent and
Inorganic thickening agent four class.
Cellulose thickener has methylcellulose, carboxymethyl cellulose, hydroxyethyl cellulose, hydroxypropyl methyl cellulose
Deng, most common of which is hydroxyethyl cellulose.The thickening mechanism of cellulose thickener cellulose thickener is hydrophobic master
Chain and surrounding water molecules, by hydrogen bond association, improve the fluid volume of polymer itself, decrease the sky that Particle free is movable
Between, thus improve system viscosity.The raising of viscosity can also be realized by the winding of strand, show as static and low cut
Cut with high viscosity, be low-viscosity under high shear.This is because when static state or low shearing speed, cellulose molecular chain is in unordered
State and make system present high viscosity；And when high shear rates, molecule is parallel to flow direction and makees ordered arrangement, it is easy to mutually
Slide, so system viscosity degradation.
Polyacrylic ester thickener can be basically divided into two kinds: one is water miscible polyacrylate；Another kind is third
Olefin(e) acid, the homopolymer of methacrylic acid or copolymer emulsion thickening agent, this thickening agent itself is acid, must be with alkali or ammonia
It is neutralized to pH8～9 and can be only achieved thickening effect, also referred to as propylene soda acid swollen thickener.Its thickening of agent for polyacrylic acid thickening
Mechanism is that thickening agent is soluble in water, and by the same sex electrostatic repulsion of carboxylic acid ion, strand is stretched to bar-shaped by helical form, from
And improve the viscosity of aqueous phase.Additionally it forms network structure also by building bridge between emulsion particle and pigment, adds system
Viscosity.
Polyurethanes thickening agent is nonionic association thickener the most newly developed.A.J.Reuvers is to association
The thickening mechanism of type polyurethane class thickening agent has made detailed research.The molecular structure of this kind of thickening agent introduces hydrophilic group
And hydrophobic group so that it is present the character of certain surfactant.When its concentration of aqueous solution exceedes a certain certain concentration
Time, form micelle, micelle and polymer particle association and form network structure, make system viscosity increase.On the other hand a molecule
Carry several micelle, reduce the animal migration of hydrone, make aqueous phase viscosity also improve.This kind of thickening agent not only rheological characteristic to coating
Produce impact, and interact with existing between adjacent latex particle, if this effect is too strong, easily cause latex
Layering.
Inorganic thickening agent is a class imbibition and forms thixotropic gel mineral.Mainly have bentonite, attapulgite,
Aluminium silicate etc., wherein bentonite is the most commonly used.Inorganic thickening agent bentonite is a kind of phyllosilicate, expands and form wadding after water suction
Shape material, has good suspension and dispersibility, is combined into colloid with appropriate water, can discharge charged micro-in water
Grain, increases system viscosity.
