Enamine coating crosslinking agent and amine
2017-4-12 20:05:40
Enamine coating crosslinking agent and amine,Acrylic resin containing enamine functional groups, amine occurs crosslinking reaction are available, and can be crosslinked at room temperature, and good storage stability.
Enamine is aldehydes or ketones with secondary amine water condensation to form a kind of unsaturated compounds, can be seen as nitrogen enol, general formula for R2C = CR - NR2.
If the two substituents on nitrogen, one for hydrogen, the formation of enamine and imine tautomer each other; If there is no hydrogen enamine nitrogen, that is, to become a stable compounds, similar to the ene alcohol ether. Enamine - imine tautomerism and ketone - enol tautomerism, general equilibrium tend to imine side, but there are a few exceptions (such as aniline).
Enamine has two reactivity, the alkylation reaction can occur on the carbon, can also occur on the nitrogen, both for the competition. With lively halogenated (such as methyl iodide, halide, benzene a/c halide, alpha halogenated ester, etc.), mainly carbon alkylation.
Enamine is typically used with at least one alpha hydrogen atoms with a secondary amine acid such as p-toluene sulfonic acid catalyst preparation, and join the strong water loss (such as titanium tetrachloride) or water segregator azeotropic reaction completely. The mechanism of the reaction as below:
Commonly used for four secondary amine hydrogen pyrrole, morpholine and six hydrogen pyridine, diminishing their reactivity from left to right. Unsymmetrical ketones react with secondary amine, mainly produce the double bond as a carbon to replace the least enamine, this is because even in the double bond of carbon will methyl pyrrole ring with four hydrogen hydrogen repel each other, reduce the stability of the product.
Enamine synthetic reaction is a reversible reaction, dilute acid, enamine hydrolyzed to ketone and secondary amines.
Acrylic resin, English name: poly real (1 - carboxyethylene) or poly real (acrylic acid). By acrylate and methyl acrylate and other resin made of olefinic monomer copolymerization, by choosing different resin structure, different formulations, production process and solvent composition, synthesis of different types, different performance and applications of acrylic resin, acrylic resin according to the differences in structure and film-forming mechanism and can be divided into thermoplastic acrylic resin and thermosetting acrylic resin.

Risk Codes: R10; R35
RIDADR: UN 3082
Safety instructions: S2; S26; S39; S61
Packing Group: III
Hazard Class: 6.1
Copolymerization with acrylate and methyl acrylate monomer synthesis of acrylic resin is outside the scope of the main absorption peaks in the solar spectrum of light, so the acrylic paint system has excellent light resistance and outdoor aging resistance.
Thermoplastic acrylic resin does not occur in the process of film crosslinked further, so its relative molecular weight is bigger, it has good light colour retention, resistance to water, chemical resistance, quick drying, construction is convenient, easy construction, painting and rework preparation of aluminum powder paint aluminum powder whiteness, good location. Thermoplastic acrylic resin in the automotive, electrical appliances, machinery, building in areas such as widely used.
Thermosetting acrylic resin refers to the structure of a certain functional groups, in the paint by amino resin, epoxy resin, polyurethane and join the reticular structure of functional groups such as reaction, thermosetting resin generally low relative molecular weight.
Thermoset acrylic coating has excellent fullness, gloss, hardness, solvent resistance, weatherability, when high temperature baking yellow discoloration, does not return. And made from amino resin is the most important application of amino - acrylic paint, currently in automobile, motorcycle, bicycle, coil and other products are widely used on.
With acrylic monomers (methyl acrylate, ethyl acrylate, n-butyl acrylate (ba) and methyl methacrylate, n-butyl methacrylate, etc.) as the basic composition, couplet network structure of the insoluble don't melt acrylic polymer.
Besides has general performance of the acrylic resin, heat resistance, water resistance, solvent resistance, wear resistance more excellent scratch resistance. A ontology pouring casting material, solution, emulsion, water-based many forms.
