Flame retardant coating crosslinking agent

Flame retardant coating crosslinking agent,Three bromine phenyl glycidyl ether or bromine cresol glycidyl ether and lower aliphatic amine such as divinyl three amine addition reaction with flame retardant crosslinking agent, the bromine content is more than 25%, have certain flame retardant after crosslinking.

Phenyl glycidyl ether colorless transparent liquid, soluble in ether, benzene, insoluble in water, with water vapor can volatilize. Store in a cool place. With a drain or sewer With strong oxidizer, strong alkali, strong acid and amine. Kept in the dark. Used as reactive diluent of epoxy resin adhesives, organic synthetic intermediate.

Phenyl glycidyl ether by phenol; Epichlorohydrin in the presence of sodium hydroxide condensation. The phenol; Sodium hydroxide; Mix to dissolve, cooled to 5 or 6 ℃, slowly add epoxy chloropropane. Stir in 25 ℃ by finish, 45 h, reactant with ether extract, extract and anhydrous potassium carbonate and dry, filtering. Filtrate recycling ethyl ether by reduced pressure distillation, collected 120-123 ℃ (1.46 kPa) fractions of epoxy propyl phenyl ether.

2 minus 2 - three bromine phenyl glycidyl ether (TBPGE) is a kind of containing epoxy group of aryl bromide flame retardants, in the presence of alkali catalyst, with hydroxyl-terminated polyether type of polyurethane prepolymer (PUP) N - H lively hydrogen open-loop alkylation reaction.

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 English alias: 2, 2 - iminodi (ethylamine); Di (2 aminoethyl) amine; Diethylenetriamine, polymer - bound; N - (2 - Aminoethyl) - 1, 2 - ethanediamine; 2, 2 '- Diaminodiethylamine; 2, 2 '- Iminodi (ethylamine); DETA.

Divinyl three amine mainly used as solvent and organic synthesis intermediates, used for making gas purifying agent (CO2), lubricating oil additive, emulsifying agent, photographic chemicals, surface active agent, fabric finishing agents, paper strengthening agent, metal, hydrometallurgy of heavy metals and chelating agent without cyanide electroplating diffusion agent, brightener, ion exchange resin and polyamide resin, etc.

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.

Electrophoretic coating mainly refers to "cathodic electrophoretic coating", is widely used in automobile industry, and applied to building materials, light industry, household appliances and other industries as well as the anti-corrosion and decorative hardware and crafts. Cathodic electrodeposition is positively charged cationic resin after electrify to the cathode, due to the increasing pH near cathode, particle exchange, cathodic coating will precipitate onto the specimen.

Cathodic electrophoretic coating of paint film adhesion, strong hiding power, high resistance to corrosion (neutral salt spray test of 1000 h). Electrophoretic paint for water-based paint, common cathode electrophoresis paint epoxy resin paint, acrylic paint and polyurethane paint. Electrophoresis there exists no problem of solvent evaporation.
