Description

Applications and water-based paint compositions of the high polymer material PAMAM as pH adjusting agent
Technical field
The present invention relates to a kind of pH adjusting agent, the technical field of water paint, more particularly, to one Application, water-based paint compositions kind using PAMAM as pH adjusting agent.
Background technology
Dendritic and dissaving polymer are all the height branch with the three-dimensional branched structure of nano-scale Change macromolecule.It has been generally acknowledged that dendrimer structure is very regular, with molecular vibrational temperature Mw/MnConnect The near or molecular structure equal to 1, generally combines complex steps.Compare with dendritic, surpass Branched polymer is no so regular, and molecular vibrational temperature is wider, and usual 1.2<Mw/Mn<2.5, because with Dendrimers have similar structure, thus performance also close to.But the letter of dissaving polymer synthetic method It is single, typically can be using one-step polymerization method synthesis.Dendritic has similar ball with dissaving polymer The cramped construction of shape, the hydrodynamics radius of gyration is small, and the degree of branching is very high, and molecular entanglement is few, therefore viscous Spend smaller with the increase change of relative molecular mass.Meanwhile, because dendritic and hyperbranched polymerization Many big compared with small molecule monomer of the molecular weight of thing, volatility is very low, does not almost have smell, belongs to ring The friendly ep-type material in border.
Water paint particularly emulsion paint is typically maintained between alkalescence, pH=7.5~10.Its important original Because including:First, high pH value can provide anionic dispersing agents stable ensure;Second, alkalescence Medium can slow down the corrosion to packing metal bucket;3rd, alkaline medium is conducive to coating and pH to be also in alkali Property the construction substrate of cement mortar form stable attachment.
Early stage adjusts pH value using NaOH and KOH, but NaOH and KOH alkalescence is too strong, right The stability and performance of product are exerted an adverse impact, rear to use small molecule amine, and such as ammoniacal liquor is adjusted Save pH value.So, substantial amounts of ammoniacal liquor is all contained in many water paint products.Ammoniacal liquor is a kind of easy The weak base of volatilization, to the irritant smell of human body, and the also easily generation pH value drift in storing process Move, cause product stability to decline, or even cause sedimentation, divide the adverse consequences such as water, have a strong impact on aqueous The use of coating.
At present, modified pH adjusting agent is the AMP-95 produced using ANGUS chemical companies of the U.S. (its main chemical compositions is -2 methyl isophthalic acids of 2- amino-propyl alcohol).AMP-95 pH value is relatively stable, The drawbacks of pH value is drifted about can be reduced when using, but it is still volatile odorous, it usually needs some gas of adapted The essence of taste smoke agent for shielding or detergent improves the smell of coating.
