Description
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,
