Embodiment 1
[0019] A kind of preparation method of antistatic type release agent is:
[0020] The temperature of the reactor is controlled at 75°C, the rotation speed is 200rpm, 120 parts of reaction medium and 8 parts of resin powder are added to the reactor, and after it is completely dissolved, 2 parts of coupling agent, 2 parts of initiator, 8 parts Add 1 part of silicone oil and 4 parts of antistatic agent into the reactor, and react for 3 hours. After the reaction is complete, add 3 parts of starch and 1 part of leveling agent into the reactor, react for 2 hours, and then lower the temperature of the reactor Raise to 80°C, carry out reflux reaction for 2 hours, stop heating, cool down to room temperature naturally, and seal the obtained substance, which is the antistatic release agent.
[0021] The resin powder is as follows: 50 parts by mass of polyvinyl alcohol, 11 parts of polyglycidol, 16 parts of polyurethane, 7 parts of polyhydroxyethyl acrylate, and 4 parts of polyacetate fib...
Embodiment 2
[0029] A kind of preparation method of antistatic type release agent is:
[0030] The temperature of the reactor is controlled at 70°C, the rotation speed is 300rpm, 110 parts of reaction medium and 6 parts of resin powder are added to the reactor, and after they are completely dissolved, 2 parts of coupling agent, 1 part of initiator, 7 parts of Add 5 parts of silicone oil and 5 parts of antistatic agent to the reactor and react for 3 hours. After the reaction is complete, add 6 parts of starch and 2 parts of leveling agent to the reactor and react for 2 hours. After raising the temperature to 80° C. for reflux reaction for 3 hours, stop the heating, cool down to room temperature naturally, and seal the obtained substance, which is the antistatic release agent.
[0031] The resin powder is: adding 45 parts of polyvinyl alcohol, 12 parts of polyglycidyl alcohol, 14 parts of polyurethane, 5 parts of polyhydroxyethyl acrylate, and 5 parts of polyacetate fiber into the mixture by...
