Physical and Chemical Properties | This product is colorless to yellowish thick liquid. It belongs to the category of thermosetting resin primary polymer. In case of cold gel, it can be diluted by cold water in any proportion. When it is gel, it is dissolved with 3~5 times of hot water (70~80 ℃). It can be used in the same bath with cationic and nonionic surfactants. From soluble to insoluble at high temperature, once finalized, it cannot be reversed. Common sense in non-acidic water can be maintained for several days. |
Use | Used as a crosslinking agent for polyacrylate and a fabric finishing agent. The product is used as a flame retardant matching resin and has achieved satisfactory results in wrinkle resistance, shrinkage resistance, flame retardancy, washability, and tactile properties of fabrics. |
It is irritating and should not come into direct contact with the skin. During operation, in addition to wearing masks and goggles, there must be good ventilation devices in the production workshop. Place in a cool and ventilated warehouse, do not store with flammable materials, and keep away from ignition sources.
Add 32kg of formaldehyde (37% aqueous solution) to the reactor, adjust the pH value to 8.0 with alkali, and slowly add 7.5kg of melamine under stirring. Heat to 70 ℃ and stop heating. The temperature naturally rises to 80-85 ℃, and stir for 1 hour. Dilute the cooling water to the specified content and stir for 15 minutes. Discharging. It is the finished product.
