Product Specification

Product package

200kg/Drum or according your requirement of  2-Propenoicacid.

Add 30g of acetone to reduce the viscosity of the system; If NCO cannot be detected in

the system after 4 hours of reaction, add acetone directly after cooling to room temperature

then Stir at 500 r/min for 20 min and add TEA to salt at room temperature for 15 min.

Disperse the mixture in water at a stirring rate of 1200 r/min, continue stirring for 40

minutes after dispersion Finally, reduce the pressure and evaporate acetone.

The preparation of PU-AC involves replacing the solvent acetone with AC monomer

during the synthesis of PU Add a certain amount of BA, MMA, TMPTA mixed monomers

and initiator AIBN to PU prepolymer (without NCO), stir for 20 minutes, and then add

TEA to form salt. After 15 minutes of reaction at 35 ℃, add the system.

Transfer the mixture into a 1L sealed reaction vessel containing a certain amount of water

and disperse it at 1200 r/min for 40 minutes. Then, raise the temperature of the dispersed

mixture 2-Propenoicacid to 75 ℃.

The PU-AC lotion is prepared after reaction for 6h at 230 r/min When other conditions

remain unchanged, the formula of synthetic PU-AC lotion is changed after adding HEA.
Different series of lotion were synthesized by the reaction temperature of PU prepolymer,

the type of capping agent and the amount of HEA.2-Propenoicacid..
