Abstract
The utility model discloses an antistatic BOPET (Biaxially Oriented Polyester) release film with light release force. The antistatic BOPET release film is divided into three layers, which orderly are a BOPET film layer, a silicone oil layer and a release layer. The three-layer BOPET release film disclosed by the utility model is compact in structure, easy to strip, small in release force on the basis of ensuring that the characteristics of a rubber surface are not affected, and better in effect, can be applied to automatic adsorption and mounting of a machine, and does not generate a newton ring. A preparation method of the BOPET release film provided by the utility model adopts a ligature coating method; the problem of high release force can be solved; meanwhile, the antistatic capacity is provided to the release film; especially the problems that the traditional antistatic coating is uneven to coat and uneven in antistatic force are solved; the practical value is promoted.

Described silicon layer is that hydrogen content is the containing hydrogen silicone oil of 0.1wt%-5 wt%, in silicon layer, is added with antistatic particle.
Preferably, described silicon layer is that hydrogen content is the containing hydrogen silicone oil of 2wt%; Described antistatic particle includes but not limited to that poly-sulfonic compound, polythiophene class compound, nickel powder, copper powder, silver powder, carbon nanotube particulate, season are by salt particle, and particle diameter is 1-20 μ m, and optimal selection is that particle diameter is the nickel powder of 10 μ m.
Described release layer includes but not limited to organic release layer of platinum oxide catalysis additional organosilicon release layer or pink salt, zinc salt, trivalent iron salt catalysis or weak acid, weak base hydrolysis siloxanes release layer, preferential oxidation platinum catalysis additional organosilicon release layer.
The preparation method of the antistatic BOPET mould release membrance of above-mentioned light off-type force, the method silicon-coating oil reservoir and the release layer that adopt line-connection type to be coated with, concrete steps are as follows,
1) antistatic particle is mixed with silicone oil;
2) silicone oil that coating mixes on the BOPET film, and precuring, form silicon layer on the BOPET film;
3) method with the line-connection type coating is coated with release layer on silicon layer;
4) enter baking oven and carry out the heat cure processing, get final product.
Preferably, described step 2) in, the silicon layer heat curing temperature is 25-50 ℃, and be 3-6min hardening time; Under 40 ℃ of heat curing temperatures, solidify 5min, best results.
Preferably, in described step 4), the release layer solidification temperature is 90-180 ℃, and be 7-15min hardening time; Under 150 ℃ of heat curing temperatures, solidify 10min, best results.
Described BOPET film blows surface moisture off with hot blast before use.
The utility model beneficial effect:
Three-layer type BOPET mould release membrance provided by the utility model, structure is compacted and is easily peeled off, and off-type force is little guaranteeing not affect on the basis of glue face characteristic, mounts applicable to the machine automatic absorbing, can not produce rainbow line, better effects if.The preparation method of the BOPET mould release membrance that the utility model provides, adopt the line-connection type coating process, can solve the higher problem of off-type force, give again simultaneously the mould release membrance antistatic effect, particularly customer service traditional coating antistatic coating, the problem that the even antistatic force of crawling is inhomogeneous, promoted its practical value.
