[0026]The present invention also provides a method of preparing an oil-soluble thick oil-up adhesive, comprising: 2,2,3,3-tetrafluoropropyl methacrylate, styrene, maleic anhydride, and armor, according to the molar ratio Eporpostate mixture, dissolve, heating, and initiation reaction to obtain an oil-soluble thick oil-up adhesive.
[0027]Preferably, the molar ratio is: 2,2,3,3-tetrafluoropropyl methacrylate: styrene: maleic anhydride: methyl methacrylate = 1: 3: 2: 10.
[0028]Preferably, the solvent selected by the dissolution process is toluene, the mass of the toluene is 90% and 110% by weight of the four monomers. This solvent toxicity is smaller than other solvents and does not affect the reaction.
[0029]Preferably, the heating temperature of the heating process is 60 ° C to 80 ° C.
[0030]Preferably, the initiator of the initiator is a peroxide, and the mass of the oxide oxide is from 1% to 2% of the four monomers.
[0031]Preferably, the initiation reaction has a time of 5 h-7 h, and he...

[0035]Example 1
[0036]The molar ratio of the reaction monomer is: 2,2,3,3-tetrafluoropropyl methacrylate: styrene: maleic anhydride: methyl methacrylate is 1: 2: 1: 9.
[0037]The preparation process is: 0.2 g of 2,2,3,3-tetrafluoromethyl methacrylate, 0.22 g of styrene, 0.1 g of 0.22 g of styrene, 0.1 g of 0.22 g of styrene, 0.1 g of 0.22 g of styrene, 0.1 g The maleic anhydride and 3.05 g of methyl methacrylate were added to the addition of 1.57 g of toluene as a solvent. When heated in the oil bath pan, stirred at a temperature of 60 ° C, dissolved by 0.714 g of sodium oxidized benzoyl. In 2 g of toluene, it was added dropwise to the three flask, and after 5 h to be reacted, the heating was stopped, and the reaction solution was evaporated under vacuum conditions, and solvent toluene was removed.

[0038]Example 2
[0039]The molar ratio of the reaction monomer is: 2,2,3,3-tetrafluoropropyl methacrylate: styrene: maleic anhydride: methyl methacrylate is 1: 4: 3: 11.
[0040]The preparation process is: 0.2 g of 2,2,3,3-tetrafluoropropyl methacrylate, 0.44 g of styrene, 0.3 g of 0.44 g of styrene, 0.3 g of 0.44 g of styrene, 0.3 g of 0.44 g of styrene, 0.3 g of styrene, 0.3 g of styrene The maleic anhydride and 3.72 g of octhacrylate were added to 2.66 g of toluene as a solvent. When heated in the oil bath pan, stirred at a temperature of 60 ° C, dissolved by 0.0932 g of the benzoyl oxide. In 2 g of toluene, it was added dropwise to the three flask, and after 5 h to be reacted, the heating was stopped, and the reaction solution was evaporated under vacuum conditions, and solvent toluene was removed.
