| Abstract: | The title aqueous polyurethane(APU) has been prepared by using polyether,dimethylol propionic acid and toluene diisocyanate(TDI) and siloxane monomer.The experimental results show that the storage stability of the modified APU is good when the post-addition technology of siloxane monomer is used.The GPC result shows that the molecular weight of APU modified by siloxane is higher than that of traditional APU.The measured properties show that the aqueous polyurethane modified by siloxane has high hardness,good contamination resistance,excellent water and solvent resistance. |
| Keywords: | aqueous polyurethane siloxame modification dimethylol propionic acid |
