Preferably：Include the raw material of following parts by weight,
Preferably：Include the raw material of following parts by weight,
The present invention to achieve the above object, using following technical scheme：A kind of preparation side of the polyurethane coating of PET film
Method includes the following steps,
(1) by nitrogen gas stirring after being dehydrated polyoxypropyleneglycol 2000, it is different that toluene two is added dropwise dropwise at 50-53 DEG C
Cyanate is mixed；
(2) dimethicone, epoxy resin, Diethylaminoethanol, trimethylolpropane, inclined benzene are added into step (1)
Three sour three monooctyl esters, diisononyl phthalate, bentonite are mixed, and whipping temp is 50-53 DEG C.
Preferably：It is 1-1.3 hours a length of when the mixing of step (2).
The beneficial effects of the invention are as follows：The present invention prepares polyurethane with polyoxypropyleneglycol and toluene di-isocyanate(TDI)
Performed polymer, then in modifying agent, chain extender, crosslinking agent prepares the modified polyurethane of better performances under the action of plasticizer etc.
Coating, coating have the advantages that mechanical strength is high, adhesive force and resistance to acid and alkali are good, water absorption rate is low.
