Preparation of a parent-modified acrylate copolymer adhesive 3

Preparation of amphiphilic oligomers. Mix 8g octadecyl alcohol, 6g maleic anhydride, and 55g toluene evenly and pour them into a round-bottom flask; The monoester of octadecyl maleate was obtained at 60℃ for 48h. 7g octadecyl maleate monoester, 5g polyethylene glycol 800, 0.8 g p-toluene sulfonic acid, and 150g toluene were poured into a round-bottomed flask, mixed evenly, and reacted at 120℃ for 4h to obtain amphiphilic oligomers.

• (1) Take 12g methyl methacrylate, 16g acrylic acid, 70g xylene, 20g ethyl acetate, and 5g acetone and mix evenly; Then, 12g dimethylacryloxy (trimethyl) hexamethyldiurethane, 3g ammonium persulfate and 2g potassium persulfide were added in the stirring state, stirring at 60℃ for 6h;
• (2) Add 5g amphiphilic oligomer, 1.5g methylene acrylamide, 1g sodium p-toluene thione-sulfonate, and 1g ammonium persulfate, stirring reaction at 70℃ for 5h;
• (3) Add 0.5g sodium metaphosphate, 0.1g citric acid, 1.6g phosphate PM2000, and 10 calcium carbonate whisker successively, stirring until evenly dispersed;
• (4) In stirring state, vacuum, parental oligomer block modified acrylate copolymer adhesive.
