Preparation of a parent-modified acrylate copolymer adhesive

Preparation of amphiphilic oligomers 12g octadecyl alcohol, 7g maleic anhydride, and 65g xylene were mixed evenly and poured into a round-bottom flask; The monoester of octadecyl maleate was obtained at 120℃ for 4h. 10g octadecyl maleate, 7.5g polyethylene glycol 600, 1.6g p-toluene sulfonic acid, and 150g toluene was poured into a round-bottomed flask, mixed evenly, and reacted at 90℃ for 16h to obtain amphiphilic oligomers.

• (1) Take 10g methacrylate, 15g ethyl acrylate, 40g toluene, 40g ethyl acetate, and 5g acetone and mix evenly; Then, 5g dimethylacryloxy (trimethyl) hexamethyldiurethane, 1g ammonium persulfate and 1g potassium persulfate were added in the stirring state, and the reaction was stirred at 60℃ for 6h.
• (2) Adding 15g of the amphiphilic oligomer, 2g methylene diacrylamide, 1.2g sodium p-toluene thiosulfate, 0.1g methyl persulfate, stirring reaction at 60℃ for 6h;
• (3) Add 0.3g sodium hydrogen phosphate, 0.3g tartaric acid, 1.4g phosphate PM1500, 2 calcium carbonate whiskers, and 5g silicon dioxide successively, stirring until evenly dispersed;
• (4) In stirring state, vacuum, parental oligomer block modified acrylate copolymer adhesive.
