[0113] The preparation method of the antistatic photocurable monomer of one embodiment, comprises the steps:
[0114] S10, dissolving the acylating reagent in an organic solvent, mixing to obtain an acylating reagent solution, and cooling the acylating reagent solution to below 5°C.
[0115] The acylating reagent used in this preparation method is a compound containing two or more acid chloride groups, such as sulfone dichloride, phosphorus oxychloride, phosphorus trichloride, phosphorus pentachloride, phosgene, polybasic acid chloride, Polybasic acid chloride, cyanuric chloride, etc.
[0116] The organic solvent can be toluene, xylene, ethyl acetate, butyl acetate, acetonitrile, tetrahydrofuran and other solvents that do not contain groups such as hydroxyl, carboxyl, amino, etc., to prevent the solvent from participating in the acylation reaction.
[0117] Preferably, step S10 is: add 1 part (number of moles) of an acylating agent to the reaction kettle, then add a certain a...
Embodiment 1
[0140] Add 10g of phosphorus oxychloride to the reaction kettle, then add 200g of butyl acetate, stir evenly, and place the container in an ice-water bath to cool down to below 5°C.
[0141] Add 22g of pentaerythritol triacrylate dropwise in the reactor to prevent the reaction from being too violent; then add 20g of triethylamine dropwise to absorb the generated hydrogen chloride, which is beneficial to the alcoholysis reaction; remove the ice-water bath and stir React for 1 hour.
[0142] Add 20 g of ATO antistatic dispersion liquid dropwise into the reaction kettle, stir and react for 3 hours, then add 10 g of butanol and stir for 1 hour to react the excess phosphorus oxychloride.
[0143] Filter the reaction residue with a 0.22 μm microporous membrane, add 200 g of deionized water, mix and extract to obtain a reaction product. The product was placed in a rotary evaporator at 70° C. to evaporate the solvent in the product to obtain a 100% solid antistatic photocurable monomer...
Embodiment 2
[0145] Add 8 g of sulfone dichloride to the reaction kettle, then add 200 g of butyl acetate, stir evenly, and place the container in an ice-water bath to cool down to below 5°C.
[0146] Add 22g of pentaerythritol triacrylate dropwise in the reactor to prevent the reaction from being too violent; then add 20g of triethylamine dropwise to absorb the generated hydrogen chloride, which is beneficial to the alcoholysis reaction; remove the ice-water bath and stir React for 1 hour.
[0147] 20 g of the aminated graphene dispersion was added dropwise into the reactor, and after stirring for 4 hours, 10 g of butanol was added and stirred for 1 hour to react the excess sulfone dichloride.
[0148] Filter the reaction residue with a 5 μm microporous membrane, add 200 g of deionized water, mix and extract to obtain a reaction product. The product was placed in a rotary evaporator at 75°C to rotate the solvent in the product to obtain a 100% solid antistatic photocurable monomer.
