2017-3-5 16:19:04
Modified polyether amine coating crosslinking agent, the main chain structure of polyether amine for containing polyether keys, the crosslinking products still have good flexibility at low temperature and cold heat shock resistance, so it can be used as a crosslinking agent. As amino modified polyether main chain and sealing end structure is different, its comprehensive performance changes.
JEFFAMINE polyether amine series crosslinking agent is a representative of the flexible crosslinking agent products. Has developed the monoamine, diamine and three amine products, recently, and developed a secondary amine, a resistance amine and poly methylene glycol (PTMEG) base polyether amine products, further widening the scope of products.
Polyoxyethylene diamine (XTJ - S90) is a kind of low relative molecular mass of the active polyether amine, crosslinking speed is four times that of ordinary polyether amine D - 230, color light, flexible, can be used alone or mixed with normal polyether amine, the crosslinking products with excellent mechanical properties and resistance to impact.
Beren and so on synthesis of A series of amino aryl ether ketone crosslinking agent, such as terminal amino poly ether bisphenol A diphenyl ketone (BPAPK), end amino 3 - isobutyl hydroquinone ether diphenyl ketone (t - BPK), etc.
With such crosslinking agent crosslinked epoxy resin as a result of the existence of ether network, improve the junction between the chain segment of kindliness and reverse characteristics, thus make the crosslinking product presents high flexibility.
Huafeng jun such as development of poly (propylene oxide polyamine, main chain of poly (propylene oxide, use sealing side of polyamine, add it to to bisphenol A epoxy resin/diethylene triamine system, with the increase of the dosage, the impact strength of the crosslinked product have improved greatly.
Zhang Entian developed A series of polyether diamine type such as crosslinking agent, including diamino diphenyl ether of bisphenol A, diamino diphenyl ether diphenyl sulfone, improves the flexibility of the crosslinked product and the wet and heat resistance.
Li-ying zhao has been developed, such as a kind of flexible chain segment, and the end of the rigid structure unit is fat amino polyether (APPEG) crosslinking agent, used in toughening modification of epoxy resin, an environmental performance of coating, at 60 ℃ the balance of the bibulous rate is about 2.1%, salt fog corrosion resistance can reach more than 500 h and amino polyurethane coating is superior to end.
Chinese name: Diethyl toluene diamine(DETDA)
Physical and chemical properties: light yellow transparent liquid, slightly soluble in water, soluble in alcohols, ethers, ketones and other polar organic solvents, and polyether, polyester polyol compatibility.
Density 1.022
Viscosity (20 ℃) ??mPa·ss290±10
Pour Point ℃-9
Boiling point of310°C
Flash Point°C161.1°C
Polyether amine application field
(1) high performance composite materials: polyether amine can be a high performance epoxy resin curing agent, used in the production of high strength, high toughness of composites;
(2) the polyurea: as key components of polyurea material, high in iron bridge, bridge, dam, large venues such as waterproof concrete structure system has a lot of application examples, and shows excellent performance;
(3) coating has lower viscosity, used in epoxy floor paint or anticorrosive coatings, can reduce the dosage of solvent, reduce the system viscosity;
(4) adhesive: as curing agent of epoxy resin, solidified completely after excellent toughness and fatigue resistance, widely used in the adhesive and structural adhesive.
Polyether amine synthesis process including intermittent and continuous two kinds of technology, it adopts the production process for the continuous fixed bed process, using the load on the carrier of metal catalysts, the advanced production equipment and technology, catalysts with high efficiency, therefore the product conversion rate is high, less side effects, low production cost and stable performance, but the equipment investment is huge.
Compared to continuous production, small batch process equipment investment, can easily switch different product categories, but low production efficiency, high cost, product quality at the same time also exists a certain gap compared with continuous method.
