What can be made with melamine and formaldehyde as raw materials

What can be made with melamine and formaldehyde as raw materials. Melamine resin can be prepared by condensation polymerization of melamine and formaldehyde, which can be used in plastics and coatings industry, and can also be used as anti-folding and anti-shrinking treatment agent for textiles.

 

(1) Application of melamine in various fields

In a large-scale application, melamine is combined with formaldehyde and other reagents to produce melamine resin. Such resins are characteristic durable thermosetting plastics used in high-pressure decorative laminates, melamine tableware, laminate flooring and dry erase boards.

Melamine foam is used as heat and sound insulation materials and polymer cleaning products.

Melamine is one of the main components of Pigment Yellow 150, which is a colorant in inks and plastics.

Melamine has also entered the manufacturing process of melamine polysulfonate and is used as a superplasticizer for the manufacture of high-strength concrete. Sulfonated melamine formaldehyde (SMF) is a polymer used as a cement admixture to reduce the water content in concrete, while increasing the fluidity and workability of the mixture during processing and pouring. It results in concrete with lower porosity and higher mechanical strength, showing improved resistance to aggressive environments and longer service life.

Due to the high nitrogen content of melamine (2/3), the use of melamine as a fertilizer for crops was envisaged in the 1950s and 1960s. However, the production of melamine is much more expensive than other common nitrogen fertilizers (such as urea). The rate of mineralization (degradation into ammonia) of melamine is very slow, making the product economically and scientifically unsuitable for use as a fertilizer.

Melamine and its salts are used as flame retardant additives in coatings, plastics and paper.

The melamine fiber Basofil has low thermal conductivity, excellent flame retardancy and self-extinguishing. This allows it to be used alone or in combination with other fibers for flame-retardant protective clothing.

Sometimes melamine is illegally added to food to increase the apparent protein content. Standard tests (such as the Kjeldahl method and the Dumars test) estimate protein levels by measuring nitrogen content, so they can be misled by adding nitrogen-rich compounds such as melamine. There are instruments available today that can distinguish between melamine nitrogen and protein nitrogen.

 

(2) The main use of melamine and formaldehyde as raw materials

Melamine resin can be prepared by condensation polymerization of melamine and formaldehyde, which can be used in plastics and coatings industry, and can also be used as anti-folding and anti-shrinking treatment agent for textiles. The modified resin can be used as a metallic paint with bright color, durability and good hardness. It can also be used for sturdy, heat-resistant decorative sheets, moisture-proof paper and gray leather tanning agents, adhesives for synthetic fireproof laminates, fixatives or hardeners for waterproofing agents, etc.

The 582 melamine resin made from melamine, formaldehyde and butanol as raw materials is used as a leveling agent for solvent-based polyurethane coatings with particularly good effects.

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 in leather processing. Condensation and polymerization with formaldehyde can produce melamine resin, which can be used in the plastics and coatings industry, and can also be used as an anti-folding and anti-shrinking treatment agent for textiles. The modified resin can be used as a metallic paint with bright color, durability and good hardness.

 

(3) Conclusion

At present, China is the world's largest exporter of melamine, and its domestic consumption is still growing at an annual rate of 10%.
