Dispersion agent
Dispersion agent generally is divided into two big types in the rubber-emulsion paint: inorganic dispersant and organic dispersing agent.Use in the inorganic dispersant maximum be the polyphosphoric acid salt, like Sodium hexametaphosphate 99, Potassium tripolyphosphate, sodium polyphosphate and TKPP.The mechanism of its effect is through hydrogen bond and chemisorption, plays the electrostatic repulsion stabilization.Organic dispersing agent comprises polyacrylate (being mainly the ammonium polyacrylate salt), PS/maleic acid salt, polyisobutene/maleic acid salt etc.Their characteristics are, produce strong absorption or anchorage effect at pigment and filling surface, and it is sterically hindered to form to have long molecular chain, and the end of the chain has water-soluble, and what have also auxilliaryly has electrostatic repulsion, reaches stable result.Make dispersion agent have the size of good dispersion effect with regard to necessary strict control molecular weight, molecular weight is too little, and is sterically hindered not enough, and molecular weight too conference generation flocculates.In addition; Owing to added Nano filling in the coating composition of the present invention; And the particle surface polarity of considering Nano filling is big, and surface energy is high, and particle diameter is little; Thereby very easily take place reuniting becomes micro-size particles and makes nanometer number of phases ratio reduce or disappear, and in coating composition of the present invention, has also added the hydrophobic nano interfacial spreading agent to promote the homodisperse of Nano filling.
In an embodiment, described dispersion agent is a ROHM homopolymer ammonium salt.
Skimmer
Employed emulsion in the rubber-emulsion paint, the dispersion agent skimmer, thickening material, raw materials such as sterilant all contain tensio-active agent.Therefore very easily produce foam.Foam has hindered the dispersion of color stuffing, has reduced usage ratio of equipment, has prolonged the production cycle, and more serious is to have brought many defectives to filming, like shrinkage cavity, and pin hole etc.It is generally acknowledged that froth breaking can be divided into following four processes: 1, skimmer is adsorbed onto the foamy surface; 2, skimmer is penetrated into the foamy surface; 3, skimmer spreads on foam surface, and the adsorption surface promoting agent; 4, the broken bubble of foam tension imbalance.Should have following characteristic according to this mechanism skimmer: 1, the surface tension of skimmer is less than the surface tension that needs froth breaking liquid self; 2, the solubleness in needing the liquid of froth breaking is as far as possible little; 3, good dispersiveness to be arranged.4, can not react with the liquid of want froth breaking, can not influence the force of cohesion of pigment in the coating and the stability of emulsion.5, stronger diffusive force to be arranged.6, can not influence the performance of finished product rubber-emulsion paint.7, unpleasant odor can not be arranged.

Thickening material
The coating thickener kind is a lot, mainly contains four types of cellulose family, polyacrylate-type thickeners, polyurethanes thickening material and inorganic thickening agents.
Cellulose thickener has methylcellulose gum, CMC 99.5, 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 ambient water molecule pass through hydrogen bond association, has improved the fluid volume of polymkeric substance itself, has reduced the free active of particle space, thereby has improved the system viscosity.Also can realize the raising of viscosity through the winding of molecular chain, showing as static and low the shearing has high viscosity, is low-viscosity under high-shear.This is that cellulose molecular chain is in state of disarray and makes system present high viscosity because when static state or low shearing speed; And when high shear rates, molecule parllel is made ordered arrangement in flow direction, is easy to mutual slip, so the system viscosity degradation.
Polyacrylate thickeners can be divided into two kinds basically: a kind of is water miscible polyacrylate; Another kind is the homopolymer or the copolymer emulsion thickening material of vinylformic acid, methylacrylic acid, and this thickening material itself is a tart, must be neutralized to pH8～9 with alkali or ammoniacal liquor and just can reach thickening effectiveness, is also referred to as propylene soda acid swelling thickening material.Its thickening mechanism of polyacrylic thickening material is that thickening material is soluble in water, and through the same sex electrostatic repulsion of carboxylic acid ion, molecular chain is stretched to bar-shaped by spirrillum, thereby has improved the viscosity of water.It also forms reticulated structure through between emulsion particle and pigment, building bridge in addition, has increased the viscosity of system.
The polyurethanes thickening material is a non-ionic type associative thickener newly developed in recent years.A.J.Reuvers has done detailed research to the thickening mechanism of association type polyurethanes thickening material.Introduced hydrophilic radical and hydrophobic grouping in the molecular structure of this type thickening material, made it demonstrate the character of certain tensio-active agent.When its concentration of aqueous solution surpasses a certain certain concentration, form micella, micella and polymer particle associate and form reticulated structure, and the system viscosity is increased.Several micellas of branch subband have on the other hand reduced the transport property of water molecules, and the water viscosity is also improved.This type thickening material not only exerts an influence to the rheological of coating, and and adjacent latex particle between exist and interact, if this effect is too strong, cause the latex layering easily.
Inorganic thickening agent is one type of water-swelling and form thixotropic gel mineral.Mainly contain wilkinite, attapulgite, pure aluminium silicate etc., wherein wilkinite is the most commonly used.The inorganic thickening agent wilkinite is a kind of layered silicate, and the suction after forms flocculent substance, has good suspension and dispersiveness, is combined into colloid with an amount of water, in water, can discharge charged corpuscle, increases the system viscosity.
In an embodiment of the present invention, described thickening material is polyurethanes rheology control agent, cellulose thickener or its compsn.Particularly for example, described thickening material is commercial polyurethane class rheology control agent (solid content is 20%, and is colourless translucent, presents similar Newtonian liquid figure), commercially available cellulose thickener (pure-natural biological stable form Mierocrystalline cellulose; Available from the commercially available prod of Aqulon, trade(brand)name Natursol250HBR).
