Abstract

In this paper, N,2- hydroxyethyl, FRC-6, hexanediol and so on were used as raw materials to synthesize and design a new type of JZP, to detect its structure by infrared spectroscopy and nuclear magnetic resonance, and to use it as a chain extender for soft chain segments, and to react with both PPG1000 and TDI, so as to prepare coating materials except TPU. this material has many characteristics. testing this material, it can be seen that the increase of JZP content has an increasing effect on the average particle size of the TPU emulsion, its viscosity is reduced and its water resistance is enhanced. at the same time, the effect of JPZ addition on the TPU is also huge, which can improve the flame retardancy of the material very well, and the application effect of the material is good.
