melamine

Melamine (chemical formula: C3H6N6), commonly known as melamine and protein essence, IUPAC named "1,3,5-triazine-2,4,6-triamino", is a triazine nitrogen-containing heterocyclic organic compound, which is used as a chemical raw material. It is a white monoclinic crystal, almost odorless, slightly soluble in water (3.1g/L room temperature), soluble in methanol, formaldehyde, acetic acid, hot ethylene glycol, glycerin, pyridine, etc., insoluble in acetone, ethers, harmful to the body, can not be used in food processing or food additives. Melamine is a trimer of aminocyanide, and the resin made from it releases a large amount of nitrogen when heated and decomposed, so it can be used as a flame retardant. It is also a metabolite of the insecticide ciprolamine in animals and plants.

Melamine resins are widely used in the manufacture and processing of wooden building formwork. It can be used for the waterproofing of the surface of the formwork and the adhesion of the wood core board to increase the number of reuse of the formwork. It can be used in the plastic and coating industry, and can also be used as an anti-folding and anti-shrinkage treatment agent for textiles. Its modified resin can be used as a metal coating with bright color, durability and good hardness. It can also be used for strong, heat-resistant decorative sheets, moisture-resistant paper and gray leather tanning agents, adhesives for synthetic fireproof laminates, fixatives or hardeners for water-repellent agents, etc. 582 melamine resin prepared from raw materials. It is used as a leveling agent for solvent-based polyurethane coatings, and the effect is excellent.

The main raw material for the manufacture of melamine formaldehyde resin, used as an organic element analysis reagent, and also used in the synthesis of organic and resin as a tanning agent and filler for leather processing. Melamine resin can be prepared by condensation and polymerization with formaldehyde, which can be used in the plastic and coating industries, and can also be used as an anti-folding and anti-shrinkage treatment agent for textiles. Its modified resin can be used as a metal coating with bright color, durability and good hardness.
