Coatings additive(s):
Dispersion agent
Dispersion agent can reach the object of dispersion color stuffing by the process that wetting, grinding and dispersion, coupling and parcel are stable, and in the present invention, dispersion agent is preferably acidic polyester class dispersion agent.
In emulsion paint, dispersion agent is generally divided into two big classes: inorganic dispersant and organic dispersing agent. Maximum in inorganic dispersant are polyphosphoric acid salts, such as Sodium hexametaphosphate 99, Potassium tripolyphosphate, sodium polyphosphate and tetrapotassium pyrophosphate. The mechanism of its effect is by hydrogen bond and chemisorption, plays electrostatic repulsion stabilization. Organic dispersing agent comprises polyacrylate (being mainly ammonium polyacrylate salt), polystyrene/maleic acid salt, polyisobutene/maleic acid salt etc. Their feature is, produces strong absorption or anchorage effect at pigment and filling surface, has longer molecular chain to form space steric hindrance, and the end of the chain has water-soluble, and what have also auxiliary has electrostatic repulsion, reaches stable result. Making dispersion agent have good dispersion effect and just must strictly control the size of molecular weight, molecular weight is too little, and space steric hindrance is inadequate, and molecular weight is conference generation flocculation too.

Thickening material
Coating thickener kind is a lot, mainly contains cellulose family, polyacrylate-type thickeners, polyurethanes thickening material and inorganic thickening agent four class.
Cellulose thickener has methylcellulose gum, carboxymethyl cellulose, Natvosol, Vltra tears etc., and wherein the most frequently used is Natvosol. The thickening mechanism of cellulose thickener cellulose thickener is that hydrophobic main chain and surrounding water molecules pass through hydrogen bond association, it is to increase the fluid volume of polymkeric substance itself, decreases the space of Particle free activity, thus improves system viscosity. The raising of viscosity can also be realized by the winding of molecular chain, show as and have high viscosity at static and low sheraing, be low-viscosity under high shear. This is because when static state or low shearing speed, cellulose molecular chain is in state of disarray and makes system present high viscosity; And when high shear rates, molecule is parallel to flow direction and makes ordered arrangement, it is easy to mutual slip, so system viscosity degradation.
Polyacrylate thickeners can be divided into two kinds substantially: a kind of is water-soluble polyacrylate; Another kind is vinylformic acid, the homopolymer of methacrylic acid or copolymer emulsion thickening material, and this kind of thickening material itself is acid, just must can reach thickening effectiveness with alkali or ammonia neutralization to pH8��9, also referred to as vinylformic acid alkali swollen thickener. Its thickening mechanism of agent for polyacrylic acid thickening is that thickening material is dissolved in water, and by the same sex electrostatic repulsion of carboxylic acid ion, molecular chain is stretched to bar-shaped by spirrillum, thus improves the viscosity of aqueous phase. It also forms reticulated structure by building bridge between emulsion particle and pigment in addition, adds the viscosity of system.
Polyurethanes thickening material is non-ionic type associative thickener newly developed in recent years. The molecular structure of this kind of thickening material introduces hydrophilic radical and hydrophobic grouping so that it is present the character of certain tensio-active agent. When its concentration of aqueous solution exceedes a certain certain concentration, forming micella, micella and polymer particle associate and form reticulated structure, and system viscosity is increased. Molecular band several micellas, reduces the transport property of water molecules, aqueous phase viscosity is also improved on the other hand. The rheological of coating is not only had an impact by this kind of thickening material, and interacts with existing between adjacent latex particle, if this effect is too strong, it is easy to cause latex layering.
Inorganic thickening agent is a class water-swelling and forms thixotropic gel mineral. Mainly containing wilkinite, attapulgite, pure aluminium silicate etc., wherein wilkinite is the most conventional. Inorganic thickening agent wilkinite is a kind of layered silicate, and expanding after water suction forms flocculent substance, has good suspension and dispersion property, is combined into colloid with appropriate water, can discharge charged corpuscle in water, increases system viscosity.
It is Natvosol, polyurethane thickener at thickening material of the present invention.
Flow agent
Flow agent can impel coating to form a film complete, smooth, uniform in drying and forming-film process, reduces the possibility producing spot and spot when brushing. Flow agent of the present invention is urethane flow agent.
