Embodiment 1
[0014] [Example 1] A new type of mixed release agent, including the following raw material formula components in parts by mass: 70-95 parts of graphite milk, 2-3 parts of salt, 7-8 parts of emulsifier, 1-5 parts of polypropylene Amide, 1-2 parts of defoamer, 1-7 parts of silicone resin, 20-30 parts of deionized water.
[0015] The release agent is a functional substance between the mold and the finished product. It is chemically resistant and will not be dissolved when in contact with the chemical components of different resins, especially styrene and amines. The release agent also has Heat and stress resistance, not easy to decompose or wear, the release agent adheres to the mold and does not transfer to the workpiece to be processed, and does not hinder painting or other secondary processing operations.
[0016] 70-100 parts of graphite milk is added to the raw material formula components in parts by mass. The graphite milk has no odor and no toxic gas generation, and has a ...
Embodiment 2
[0024] [Example 2] A new type of mixed release agent, including the following raw material formula components in parts by mass: 70 parts of graphite milk, 3 parts of salt, 7 parts of emulsifier, 1 part of polyacrylamide, 1 part of defoamer, 3 parts silicone resin, 20 parts deionized water.
[0025] The preparation process is as follows:
[0026] Add graphite milk and silicone resin into a container, heat to 50-65°C, stir and dissolve to make an oil phase solution, put salt into another container, add appropriate amount of deionized water to dissolve completely, and then add polyacrylamide , after stirring evenly, add emulsifier, finally add defoamer, stir evenly and heat to 60-80°C to make water phase solution; The water phase is slowly added to the oil phase. At this time, it is necessary to stir quickly and add a small amount to make it emulsify slowly, invert the phase, and make the solution uniform. The stirring speed is gradually slowed down as the emulsification temperatu...
Embodiment 3
[0027] [Example 3] A new type of mixed release agent, including the following raw material formula components in parts by mass: 85 parts of graphite milk, 2 parts of salt, 8 parts of emulsifier, 3 parts of polyacrylamide, 2 parts of defoamer, 4 parts silicone resin, 25 parts deionized water.
[0028] The preparation process is as follows:
[0029] Add graphite milk and silicone resin into a container, heat to 50-65°C, stir and dissolve to make an oil phase solution, put salt into another container, add appropriate amount of deionized water to dissolve completely, and then add polyacrylamide , after stirring evenly, add emulsifier, finally add defoamer, stir evenly and heat to 60-80°C to make water phase solution; The water phase is slowly added to the oil phase.
