[0030] The synthesis steps of the low refractive index fluorine-containing acrylic resin photopolymer film-forming agent are as follows:
[0031] Step 1: First take 60g of anhydrous ethanol as a solvent and divide it into two parts, the first part is 24g and the second part is 36g. The first part of the solvent was added to the four-necked flask, the temperature was controlled at 60°C, and nitrogen was introduced for 10min.
[0032] Step 2: Mix the mixed monomer, initiator and the second solvent and pour it into a constant pressure funnel to form a mixed liquid, slowly drop the mixed liquid into the four-necked flask, and control the dropping time to 4h; the stirring rate is controlled 200r / min, pass nitrogen, and control the temperature at 60°C.
[0033] Described mixed monomer is obtained by the following way: 8 g of methyl methacrylate, 8 g of hydroxypropyl methacrylate, 14 g of butyl acrylate, 2 g of acrylic acid and 23 g of dodecafluoroheptyl methacrylate are mixed to fo...

[0044] The synthesis steps of the fluorine-containing acrylic resin photopolymer film-forming agent are as follows:
[0045] Step 1: first take 60g of solvent acetone, divide into two parts, the first part is 24g, the second part is 36g, the first part of acetone is added to the four-necked flask, the temperature is controlled at 80 ° C, and nitrogen is introduced for 10min;
[0046] Step 2: Mix the mixed monomer, the initiator and the second solvent and pour it into a constant pressure funnel to form a mixed liquid. The mixed liquid was slowly and uniformly added dropwise to the first portion of acetone, and the dropwise addition time was controlled to 2h; during the dropwise addition, the stirring was continued, the stirring rate was controlled at 400 r / min, the nitrogen was passed through, and the temperature was controlled at 80°C.
[0047] Mixed monomers: 8 g of reaction monomers methyl methacrylate, 8 g of hydroxypropyl methacrylate, 14 g of butyl acrylate, 2 g of acryli...

[0054] The synthesis steps of the fluorine-containing acrylic resin photopolymer film-forming agent are as follows:
[0055] Step 1: First, take 60 g of a mixed solvent of butyl acetate and xylene in a mass ratio of 2:1, and divide it into two parts, the first part is 24 g and the second part is 36 g. The first part of the solvent was added to a four-necked flask, the temperature was controlled at 70° C., and argon gas was introduced for 10 min.
[0056] Step 2: Mix the mixed monomer, the initiator and the second solvent and pour it into a constant pressure funnel to form a mixed liquid. The mixed liquid was slowly and uniformly added dropwise to the first part of the solvent, and the dropping time was controlled to 3h; the dropping process was continuously stirred, the stirring rate was controlled at 300 r / min, and the temperature was controlled at 70 °C with argon.
[0057] The initiator is 0.6 g of dibenzoyl peroxide.
[0058] Described mixed monomers: 8 g of reaction mon...
