Name | Trimethylolmelamine Resin |
Synonyms | Trimethylolmelamine Resin N,N',N''-Trihydroxymethyl-melamin N,N',N''-Trihydroxymethyl-melamin [german] Tris(hydroxymethyl)-1,3,5-triazine-2,4,6-triamine 1,3,5-Triazine-2,4,6-triamine, tris(hydroxymethyl)- |
CAS | 51505-94-3 |
Molecular Formula | C6H12N6O3 |
Physical and Chemical Properties | This product is white solid. It belongs to the primary shrinkage of hot solid resin. Insoluble in water, soluble in 80 ℃ hot water. Present a clear solution. It is easy to produce intermolecular polymerization in weakly alkaline medium. Therefore, the stability is poor, should be used now. |
Use | Used as a fabric shrinkproof and wrinkle resistant finishing agent to make the fabric firm, plump, and dust-free. |
It is irritating and should not come into direct contact with the skin. Place in a cool and ventilated warehouse and do not store with flammable materials. Stay away from ignition sources.
Add 16kg of formaldehyde (37% solution) to the reactor and adjust the pH to 8.0 by adding 0.2kg of triethanolamine. Add 10kg of water under stirring, then slowly add 7.5kg of melamine, uniformly raise the temperature to 68 ℃, and stop heating. Automatically raise the temperature to 76 ℃ and stir between 76~79 ℃ for 30 minutes. Cool down and mix with water to adjust the content according to the specifications. The discharge is finished product.
Use | used as a fabric anti-shrinkage, anti-wrinkle finishing agent to make the fabric stiff, full, and dust-free. |
production method | 16 kg of formaldehyde (37% solution) was added to the reactor, the pH was adjusted to 0.2 by adding 8.0 of triethanolamine. Under stirring, 10 kg of water was added, and then 7.5 of melamine was added to each level. The temperature was raised to 68 ° C., and the heating was stopped. The temperature was raised to 76 degrees C, and the mixture was stirred at 76~79 degrees C for 30 min. Cooling, mixing does not adjust the content according to the index. The output is the finished product. |
