It is coated on corona surface and is formed after 36 parts of ethyl ester hybrid modulation.
PET film be optical grade high transparency PET film or plain edition biaxial stretching polyester PET film, the PET film
With a thickness of 12um-188um, the mould release is 7458 type mould releases of Dow Corning Corporation's production, and the off-type force regulator is
7201 type mould releases of Dow Corning Corporation's production, the crosslinking agent are 7672 type crosslinking agents of the Dow Chemical Company, the attachment addition
Agent is that 9176 types of the Dow Chemical Company adhere to additive, and the catalyst is 4000 type catalyst of the Dow Chemical Company.
Release layer by 60 parts of butanone, 30 parts of 120# gasoline, 10 parts of isopropanol, 82 parts of mould release, 18 parts from
Type power regulator, 13 parts of crosslinking agent, 4 parts of attachment additive, 5 parts of catalyst, 40 parts of toluene, the mixing of 30 parts of ethyl ester
It is coated on corona surface and is formed after modulation.
The hybrid modulation process of release layer successively includes:
1) prepared and diluted agent: toluene, butanone, ethyl ester, 120# gasoline and isopropanol, which are successively sequentially added into agitator, to be made
2 minutes formation mixed solvents are at the uniform velocity stirred with agitator air；
2) mould release is slowly added into the in the mixed solvent stirred evenly and continues stirring 10 minutes；
3) off-type force regulator is slowly added into again after small glass is first stirred with glass bar, is stirred 3 minutes；
4) crosslinking agent is slowly added into again after small glass is first stirred with glass bar, is stirred 2 minutes；
5) attachment additive is slowly added into again after small glass is first stirred with glass bar, is stirred 1 minute；
6) catalyst is slowly added into again after small glass is first stirred with glass bar, is stirred 2 minutes.
The beneficial effects of the present invention are: explosion-proof release film of the invention, can effective protection rupture pressure disc, and effectively solve
Release film surface has the problems such as crystal point, rainbow, piebald and lines, moreover it is possible to be effectively improved and control its stability, when use subtracts
The generation of few defective products.
