Embodiment 1
[0062] Prepare the self-healing emulsion with core-shell structure according to the composition and consumption of raw materials in Table 1 and the following steps:
[0063] a. Add still bottom liquid A to the polymerization kettle with stirring device, condenser and peristaltic pump feeding device;
[0064] b. Add pre-emulsion B1 to the first pre-emulsification tank, stir and mix evenly for later use;
[0065] c. Add thermal initiator solution C1 to thermal initiator tank one;
[0066] d. Add pre-emulsion B2 to the second pre-emulsion, stir and mix evenly for later use;
[0067] E, add thermal initiator solution C2 in thermal initiator tank two;
[0068] f. When the temperature in the polymerization tank reaches 80°C, add 10% of the pre-emulsion B1 and 10% of the thermal initiator solution C1 into the tank, and then add the remaining pre-emulsion B1 and thermal initiator dropwise to the polymerization tank at the same time. Initiator solution C1; when pre-emulsion B1 and C1 ...
Embodiment 2-5
[0074] The self-healing emulsion was prepared according to the raw material composition in Table 1, and other operating conditions and methods were the same as in Example 1.
