| Abstract: | During the in-situ polymerization,solvent oil as the core of the microcapsules,the urea-melamine- formaldehyde resin as the shell of the microcapsules.Firstly the system is alkaline,then it changes to acidic. Using condensation polymerization process adding system modifier,10～20μm and 93% microcapsules were obtained.The microcapsules have smooth shell.The microcapsules apply to rubber pressure adhesive, the produces have good performance. |
