2017-3-14 21:57:59
Basic class coating crosslinking agent: including aliphatic diamine and polyamine, aromatic amines and other nitrogen compounds and modified alicyclic amine.
Aromatic amino attached directly to the aromatic ring in multivariate amine, compared with aliphatic amine diversity, weak alkali, reaction influenced by aromatic ring space steric hindrance, crosslinking rate dropped substantially, tend to be heated to further crosslinking. But crosslinking content than fat amine system of crosslinking content in heat resistance, good chemical resistance.
Aromatic amine diversity must be modified to make adduct, etc., or join a catalyst, such as phenol, salicylic acid, benzyl alcohol, etc., to make good crosslinking agent, can at low temperature crosslinking, paint the calorific value of the blend is not high, good corrosion resistance, acid resistance and heat resistance of water, widely used in the factory floor coating, splashing drop resistance, abrasion resistance. Aromatic amine diversity crosslinking agent mainly have 4, 4 '- diamino diphenyl methane, 4, 4' - diamino diphenyl sulfone, m-phenylene diamine, etc.
On the molecular structure of the crosslinking agent with excellent hydrophobic and room temperature high reactivity (with double bond) of flexible chain long fat, also with a benzene ring structure of chemical resistance, make its have general phenolic aldehyde amine rapid crosslinking properties at low temperature, moisture, and is generally low molecular polyamide crosslinking agent of long life.
Fatty amine, refers to the length of carbon chain within the scope of the C8 C22 - the major types of organic amine compound, it is the same as general amine, primary amine, secondary amine and tertiary amine and polyamine four categories, and the primary, secondary, tertiary amine depends on the number of hydrogen atoms are replaced by alkyl of ammonia.
Aliphatic amine is ammonia organic derivatives, C8-10 short chain fatty amine has certain solubility in water, long chain aliphatic amine generally insoluble in water, room temperature is liquid or solid, is alkaline, as an organic alkali of the skin and mucous membranes with a stimulus and corrode action.
Fatty alcohol as raw material to synthesis. Is mainly composed of fatty alcohol and dimethylamine reaction single alkyl dimethyl tertiary amine, fatty alcohol and a methylamine reaction with alkyl methyl tertiary amines, fatty alcohols generated three alkyl tertiary amine and ammonia reaction.
Fatty acid as raw material to synthesis. First fatty acid and ammonia reaction to generate nitrile, fat fat fat hydrogenation generate nitrile primary amine or secondary amine, primary amine or secondary amine im hydrogenation of methyl tertiary amine, primary amine by nitrile ethylation after hydrogenation can generate diamine, further by cyanide diamine ethylation, hydrogenation can generate three amine, three amine further by nitrile ethylation, hydrogenation can generate tetramine.

One of the most successful modified fatty amines (ring) should be adipic amine adduct and whorls diamine and adduct. Hexamethylenediamine alone is rarely used as a crosslinking agent, but will hexamethylenediamine through modification can be made into useful liquid complaisant agent and sexual intercourse.
Its crosslinking flexibility than with polyamide resin and whorls diamine modified crosslinking system more and more than 00% elongation in l. Literature reports, hexamethylenediamine and c. aliphatic glycidyl ester and c. one, single glycidyl ether alkyl phenol reaction, liquid made of crosslinking agent has good storage stability, small irritating to the skin, crosslinking with flexure resistance, low temperature resistance and chemical resistance. Jing-min liu and others with reactive diluent after adjusting the viscosity of epoxy resin, and hexamethylenediamine flexibility of crosslinking agent was addition reaction
, 12 h under room temperature (25 ~ C)/crosslinked epoxy resin, the epoxy resin crosslinked with transparency and flexibility. Tian Xinghe et al. Synthesis of J series crosslinking agent, compared with the commonly used aliphatic amine crosslinking agent, the crosslinking agent of colour and lustre and good storage stability, low toxicity, low exotherm, its flexibility is expected to reduce or eliminate the internal stress of crosslinking content, improve the mechanical properties and thermal shock performance.
Aromatic amine refers to have a sexual substituent aromatic amine - - NH2, NH - or nitrogen groups connected to an aromatic hydrocarbon, aromatic hydrocarbon structure usually contains one or more of the benzene ring. Aniline is the most simple example these compounds. Aromatic amine molecules high reactivity.
In aromatic amine, on the nitrogen lone electron pair occupy the SP2 hybrid orbitals, and benzene ring of PI electron orbital overlap, the formation of nitrogen and benzene ring, conjugated PI molecular orbitals.
