| titleOfInvention | A kind of hindered phenol damping modification agent and preparation method thereof |
| abstract | A kind of preparation method of hindered phenol damping modification agent is by 3- (3- tertiary butyl-4-hydroxy -5- aminomethyl phenyl) propionic acid or 3- (3,5- di-tert-butyl-hydroxy phenyl) propionic acid and 1,12- dodecanediol, add catalyst, water entrainer carry out double esterification modification obtain.The present invention prepares hindered phenol damping modification agent synthesis and post-processing is simple and efficient, it is added in hindered phenol material, hindered phenol material over time may make not reunite, damping capacity greatly promotes, to enable hybrid damping material obtained to keep original damping capacity for a long time, stability is excellent, hindered phenol modifying agent of the present invention purity is high, impurity is few, storage process will not the moisture absorption it is rotten, product quality is suitable with when just producing after long-term placement, therefore shelf life is long, is 24 months, raw material of the present invention is easy to get, preparation process simple possible is worth marketing application. |
