Melamine, also known as Melamine, IUPAC named "1,3,5-triazine-2,4,6-triamine", is a triazine nitrogen-containing heterocyclic organic compound, which is used as chemical raw material.
Melamine resin can be prepared by condensation polymerization with formaldehyde, which can be used in plastic and coating industries, and also as anti-folding and anti-shrinking agent for textile fabrics. The modified resin can be used as a metal coating with bright color, durability and good hardness. It can also be used for strong and heat-resistant decorative sheet, moisture-proof paper and gray leather tanning agent, adhesive for synthetic fireproof laminate, fixing agent or hardener for waterproof agent, etc. 582 melamine resin prepared from melamine, formaldehyde and butanol. As a leveling agent for solvent-based polyurethane coatings, the effect is particularly good.
The main raw material for manufacturing melamine formaldehyde resin is used as organic element analysis reagent, and also used for the synthesis of organic and resin as tanning agent and filling agent for leather processing. Melamine resin can be prepared by condensation polymerization with formaldehyde, which can be used in plastic and coating industries, and also as anti-folding and anti-shrinking agent for textile fabrics. The modified resin can be used as a metal coating with bright color, durability and good hardness.
China's research and development of melamine fiber started late. It began in 2000. Due to its rapid development, since 2005, China has become a country with large capacity, the largest consumption and the largest export of melamine in the world. The melamine industry has been in a serious surplus for a long time.
The raw material of melamine is urea, and most of the melamine production enterprises are nitrogen fertilizer production enterprises relying on their urea production capacity, and a small part of purchased urea is produced, generally close to large-scale urea production areas. According to the industry statistics in 2012, China's melamine production enterprises are mainly concentrated in Sichuan, Shandong, Henan and Xinjiang. Sichuan, Shandong, Henan and Xinjiang are rich in natural gas and coal resources, and there are many large nitrogen fertilizer enterprises. The melamine production capacity in this region accounts for about 75% of the domestic production capacity.
The composition of melamine consumption in China is basically the same as that in the world. The main application fields are wood processing, molded plastics, adhesives and coatings, and the main consumption markets are concentrated in the light industry developed areas such as southern Jiangsu, Zhejiang and Guangdong.
