The present invention discloses an ultra-light anti-adhesion release film preparation method, which comprises: 1, mixing 3-4 parts of D120
solvent oil, 3-4 parts of D30
solvent oil, 4-5 parts of
butanone, and 1-1.5 parts of isopropanol to obtain a mixture as a
solvent, adding 1-1.2 parts of a 7458
silicone oil main agent, 0.1-0.2 part of a 7672 cross-linking agent, 0.02-0.03 part of a 297 anchoring agent, and 0.05-0.06 part of a 4000 catalyst, stirring for 30-40 min at a speed of 1200-1300 rotation / min, filtering with a 200-230 mesh
filtration screen, using within 3-3.5 h, carrying out raw film treatment, precisely
coating, carrying out
drying curing, and carrying out material receiving winding; 2, mixing 2-2.5 parts of D120 solvent oil, 2-2.5 parts of D30 solvent oil, 2.5-3 parts of
butanone and 0.8-1.2 parts of isopropanol to obtain a mixture as a solvent, adding 0.8-1 part of a 9106
silicone oil main agent, 0.1-0.2 part of a 7672 cross-linking agent, 0.02-0.03 part of a 297 anchoring agent, and 0.06 part of a 4000 catalyst, stirring for 30-40 min at a speed of 1200-1300 rotation / min, filtering with a 200-230 mesh
filtration screen, using within 3-3.5 h, carrying out raw film treatment, precisely
coating, carrying out
drying curing, and carrying out material receiving winding; and 3, carrying out post-curing treatment. According to the present invention, the produced release film has the light
transmittance of more than 88%, has the mist degree of less than 3, and has the
peel force stability (normal temperature) of 3-5 g.
