Industry share: Preparation of a two-parent modified acrylate copolymer adhesive 1

16g octadecyl alcohol, 3.5g maleic anhydride, and 155g toluene were mixed evenly and poured into a round-bottom flask; The monoester of octadecyl maleate was obtained at 120℃ for 4h. 7g octadecyl maleate monoester, 8.5g polyethylene glycol 600, 0.8 g p-toluene sulfonic acid, and 65g toluene was poured into a round-bottom flask, mixed well, and reacted at 95℃ for 12h to obtain amphiphilic oligomers.

Preparation of acrylate copolymer adhesive

(1) Take 6g methyl methacrylate, 4g butyl acrylate, 65g toluene, and 15g ethanol mixed evenly; Then 20g bisphenol A-glycyl glyceryl methacrylate resin (Bis-GMA) and 1g potassium persulfate were added in the stirring state, and the stirring temperature was 70℃ for 4h.

(2) Add 8g amphiphilic oligomer, 0.6g glycol dimethacrylate, 1g ammonium persulfate, stir and react at 75℃ for 5h;

(3) Add 0.1g ethylenediamine glyoxalic acid, 0.2g sodium hydrogen phosphate, 1g phosphate PM1510, and 8g silicon dioxide, and stir until evenly dispersed;

(4) In stirring state, vacuum, parental oligomer block modified acrylate copolymer adhesive.
