Amine coating crosslinking agent
2017-3-16 16:49:03
Amine coating crosslinking agent,Secondary amine and primary amine crosslinking effect of epoxy resin by active hydrogen on the nitrogen atom of epoxy group, and makes the crosslinking of crosslinking. Multiplex aliphatic amine such as ethylenediamine and hexamethylenediamine, divinyl three amine, triethylene tetramine and diethyl amino propylamine activity is bigger, can make epoxy cross-linking cross-linking at room temperature; And low aromatic amine diverse activities, such as m-phenylene diamine, crosslink to completely at 150 ℃.
After replaced by alkyl amine is ammonia hydrogen atoms of organic compounds. Ammonia in one, two, or three hydrogen atoms are replaced by alkyl compounds generated, respectively called first amine, primary amine, second amine (secondary amine) and the amine (tertiary amine). Their general formula is: RNH2 - primary amine, R2NH - secondary amine, R3N - tertiary amine. Amines are widely exist in nature, have very important physiological functions. As a result, most of the drugs contain amine functional group - amino. Many proteins, nucleic acids, hormones, antibiotics and alkaloid, contain amino, is amine complex derivatives.
Divinyl three amine has hygroscopic transparent yellow viscous liquid, stimulating ammonia smell, flammable, in strong alkali. Soluble in water, acetone, benzene, ethanol, methanol, hardly soluble in n-heptane, for copper and its alloy corrosive. Melting point - 35 ℃, boiling point 207 ℃, relative density 0.9586 (20, 20 ℃), the refractive index of 1.4810. Flash point is 94 ℃. This product is the reaction of secondary amine, easy to react with a variety of compounds, its derivatives have a wide range of USES. Easy to absorb moisture and carbon dioxide in the air.
Divinyl three amine main use: use the credential that catalyzes the complexing indicator, gas purifying agent, epoxy resin crosslinking agent, film for textile, also used in synthetic rubber. Active hydrogen equivalent to 20.6. Every 100 standard resin with 8 to 11. Crosslinking: 25 ℃ for 3 hours + 200 ℃ for 1 hour clock or 25 ℃ for 24 hours. Performance: the applicable period of 50 grams of 25 ℃ for 45 minutes, thermal deformation temperature of 95-124 ℃, the bending strength of 1000-1160 kg/cm2, the compressive strength of 1120 kg/cm2, the tensile strength of 780 kg/cm2, elongation is 5.5%, the impact strength 0.4 ft - pounds/rockwell hardness of 99-108. Dielectric constant (50 hz, 23 ℃), power factor 4.1 (50 hz, 23 ℃) 0.009 volume resistance 2 x1016 Ω - cm normal temperature crosslinking, toxicity, heat quantity, suitable period is short.
Sanya is C6H18N4, ethyl tetramine formula is its strong alkali medium viscosity and light yellow liquid. Sanya ethyl tetramine except as a solvent, also used in the manufacture of epoxy crosslinking agent, metal chelating agent and synthetic polyamide resin and ion exchange resin, etc.

Triethylene tetramine is strong alkali medium viscosity yellow liquid, and its volatile under diethylene triamine, but the nature of the phase approximation. Boiling point: 266-267 ℃ (272 ℃), 157 ℃ (2.67 kPa), 12 ℃, freezing point (20, 20 ℃), relative density 0.9818, refractive index (nD20) 1.4971, flash point 143 ℃, spontaneous combustion point 338 ℃. Soluble in water and ethanol, slightly soluble in ether.
Flammable. Low volatile, hygroscopicity strong, strong alkaline. Can absorb carbon dioxide from the air. Combustible, contact flame and high temperature have the risk of burning. Corrosion resistance is strong, can stimulate the skin mucous membrane, eyes and respiratory tract, and cause skin allergy, such as bronchial asthma symptoms.
Triethylene tetramine react with strong oxidizer contact, there is a risk of combustion and explosion. React with nitrogen compounds, chlorinated hydrocarbon contact. React with acid exposure. And amino compounds, isocyanate, alkenyl oxide, epoxy chloropropane, aldehydes, alcohols, ethylene glycol, phenol, cresol, caprolactam solution cannot compatibility. Contact with cellulose nitrate react. And acrolein, acrylonitrile, tertiary butyl nitro acetylene, ethylene oxide, chlorine formic acid isopropyl ester, maleic anhydride, 3 isobutyl aluminum cannot compatibility. Corrosion of copper, copper alloy, cobalt and nickel.
Triethylene tetramine production methods for dichloroethane ammoniation method. Will be 1, 2 - dichloroethane and ammonia into tubular reactor in 150-250 ℃ temperature and hot pressing ammonification reaction under 392.3 kPa pressure.
Liquid with alkali neutralization reaction, get mixed amine, the concentration at the same time to remove sodium chloride, then coarse vacuum distillation, the interception of between 195-215 ℃ fraction, a quick finished product. This method at the same time the all-round ethylenediamine; Diethylene triamine; More than five and four ethylidene ethylidene polyamine, by controlling the temperature distillation column amine mixture, interception of different fractions separation.
