Alicyclic amine diversity coatings crosslinking agent
2017-3-4 23:34:56
Alicyclic amine diversity coatings crosslinking agent, alicyclic amine as the molecular structure to contain alicyclic (cyclohexyl, impurity oxygen and nitrogen atoms six-member ring) amine compounds. Most of low viscosity liquid, applicable period is longer than fatty amine, crosslinking of chromaticity, gloss is better than that of fatty amine and polyamide; Medium temperature crosslinking, the price is high, good transparency, good weatherability, crosslinking content of high mechanical strength; Ambient crosslinking of the modified products.
The most common for isophorone diamine (alicyclic amine). They are usually, though, is not directly used as crosslinking agent of paint, but by introducing new addition or condensation reaction using modified molecular structure.
Three, aromatic amine
M-phenylene diamine
Between benzene dimethylamine
4, 4 '2 amino diphenyl methane (DDM)
4, 4 '2 amino diphenyl sulfone (DDS)
The characteristics of aromatic amine diversity crosslinking agent
Advantage: the crosslinked heat resistance, chemical resistance, mechanical strength than aliphatic amine. (molecule contains one or more of the benzene ring)
Disadvantages: (1) active low, mostly crosslinking after heating.
Reason: compared with aliphatic amine diversity, nitrogen atoms on the electron cloud density is reduced, makes the alkaline, and the steric effect of benzene ring;
(2) most of the solid, its high melting point, poor manufacturability.
Aromatic amine cannot directly as a crosslinking agent of coating at room temperature, but to be liquefied, bottom coating can be used as the crosslinking agent. Such as, aromatic amine diversity with single glycidyl ether reaction liquid adduct. Such as 590-31, H, T - 113, crosslinking agent, etc.
Alicyclic compounds. The carbon in these compounds molecular chain compounds are connected into a chain, because it was first found in fat, so also called aliphatic compounds.
Chinese name: Diethyl toluene diamine(DETDA)
Diethyltoluenediamine Raw material ：
TDA industrial, Sichuan production
Ethylene (Et) polymer grade, Shanghai production
TEA industrial imports
A reagent grade additives
According to the basic skeleton of carbon atoms in different organic compounds are divided into three categories: 1. The chain compounds The carbon in these compounds molecular are connected into a chain, because its was originally found in fat, so also called aliphatic compounds. 2. Carbon ring compounds This kind of compound molecules composed of carbon atom is contained in annular structure, therefore calls carbocyclic compounds.
It can be divided into two categories: alicyclic compounds: is a kind of nature and aliphatic compounds similar carbon ring. Aromatic compounds: is a molecular compound containing benzene ring or thick benzene system. 3. The heterocyclic compound: ring of such compounds in addition to the carbon atom, also contain other elements of the atoms, called heterocyclic compounds.
Example: such as double loop pentadiene as raw material to synthesis a new type of three functional groups liquid alicyclic epoxy resin. Through infrared spectrum, nuclear magnetic resonance hydrogen spectrum and mass spectrum etc. The structure of the intermediates and epoxy resin have been characterized.
The alicyclic epoxy resin by cationic initiator six fluoride phosphate dimethyl phenyl iodide anchor for uv-curable, studied its curing light activity, at the same time discusses the oxidant benzoyl peroxide sensitization effect of the uv curing system. The research results show that the new synthesis of alicyclic epoxy resin using dimethyl phenyl iodide anchor six fluoride phosphate can cause light curing, benzoyl peroxide significantly accelerated the light curing speed, curing film has good thermal stability.
Alicyclic compounds refers to the hydrocarbon molecules contain carbon ring, which can be saturated and unsaturated carbon ring, a typical carbon ring ring and six-member ring five yuan, five yuan carbon ring of the more important is conjugate structure, and of course multiple hydrocarbon of ring structure, such as serial, and ring, new ring bridge hydrocarbon, etc.
