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 […]
The use of emulsion acrylic pressure-sensitive adhesive, for low surface energy substrates such as polyolefin surface adhesion, is poor. Therefore, tackifiers often need to be added to improve their sticking performance. Viscosifying resin was usually mixed with rosin resin as an emulsion acrylic pressure-sensitive adhesive. Rosin resin source is an acidic natural resin extracted from […]
