Basic introduction: Melamine (chemical formula: C3H6N6), commonly known as melamine and albumen essence, is a triazine nitrogen containing heterocyclic organic compound named "1,3,5-triazine-2,4,6-triamine" by IUPAC, and is used as chemical raw material. It is a white monoclinic crystal, almost tasteless, slightly soluble in water (3.1g/L room temperature), soluble in methanol, formaldehyde, acetic acid, hot ethylene glycol, glycerin, pyridine, etc., insoluble in acetone, ether, harmful to the body, and cannot be used for food processing or food additives. Melamine is the trimer of cyanamide. When the resin made of melamine is heated and decomposed, it will release a large amount of nitrogen, so it can be used as a flame retardant. It is also a metabolite of the insecticide cyromazine in animals and plants.
Basic Properties: Appearance and properties: white, monoclinic crystal. Melting point (ºC):>300 (sublimation) Relative density (water=1): 1.573 Relative vapor density (air=1): 4.34 Saturated vapor pressure (kPa): 6.66 Solubility in water (20 ºC): 0.33g Solubility: insoluble in cold water, soluble in hot water, slightly soluble in ethylene glycol, glycerin, ethanol, insoluble in ether, benzene, carbon tetrachloride. molecular structure Chemical formula (molecular formula) C3H6N6 Relative molecular weight 126.15
Usage: Melamine resin can be prepared by condensation polymerization with formaldehyde, which can be used in plastics and coatings industry, and also can be used as anti crease and anti shrink treatment agent for textiles. The modified resin can be used as a metallic coating with bright color, durability and good hardness. It can also be used for solid and heat-resistant decorative sheet, moisture-proof paper and grey leather tanning agent, adhesive for synthetic fireproof laminate, fixing agent or hardening agent for waterproof agent, etc. 582 melamine resin is prepared from melamine, formaldehyde and butanol. As a leveling agent for solvent based polyurethane coatings, the effect is excellent. The main raw materials for manufacturing melamine formaldehyde resin are used as organic element analysis reagents, as well as organic and resin synthesis as tanning agent and filler for leather processing.
