[0021] Example 1
[0022] A manufacturing method of heat-shrinkable self-adhesive vacuum plating protective film, including the following steps:
[0023] (1) Synthesize polyvinyl polyacrylate first: Dissolve 5 kg of glycidyl acrylate, 30 kg of methyl methacrylate, 10 kg of ethyl acrylate, 50 kg of butyl acrylate, and 5 kg of hydroxyethyl methacrylate in 200 mL of ethyl acetate. Obtain the comonomer solution from the ester, take out 1 / 2 comonomer solution, add 0.5kg azobisisoheptonitrile initiator and polymerize for 1 h at 80℃, then add the remaining 1 / 2 comonomer solution and the remaining 0.5 kg of azobis-isoheptonitrile initiator, after the addition is complete, continue to react for 3h, then, maintaining the reaction temperature unchanged, slowly add 0.2kg of triethylamine catalyst and 5kg of acrylic functional monomer, after the addition, continue React for 3 hours, and finally, use a rotary evaporator to concentrate the solution, let the solvent volatilize, and then obtain th...

[0026] A manufacturing method of heat-shrinkable self-adhesive vacuum plating protective film, including the following steps:
[0027] (1) Synthesize polyvinyl polyacrylate first: Dissolve 10 kg of allyl glycidyl ester, 32 kg of methyl methacrylate, 40 kg of butyl acrylate, 10 kg of isooctyl acrylate, and 8 kg of hydroxyethyl methacrylate. Obtain the comonomer solution in 200L of toluene, take out 1 / 2 comonomer solution, add 0.6kg azobisisobutyronitrile initiator and polymerize at 85℃ for 1 h, then add the remaining 1 / 2 comonomer solution dropwise And the remaining 0.4 kg of azobisisobutyronitrile initiator, after the addition is complete, continue to react for 3h, then, maintaining the reaction temperature unchanged, slowly add 0.2kg of cetyltrimethylammonium bromide catalyst and 5kg of coat After the addition of the functional monomer of aconic acid, the reaction is continued for 3 hours. Finally, the solution is concentrated using a rotary evaporator to allow...
