| titleOfInvention | Acrylic acid rosin-based high-molecular surfactant and preparation method and application thereof |
| abstract | The invention discloses an acrylic rosin-based high molecular surfactant which is obtained by copolymerizing oleophylic monomer acrylic rosin glycidyl methacrylate and hydrophilic monomer polyethylene glycol methacrylate, wherein the general structural formula of a main product is as follows: wherein the molecular weight range of the methacrylic acid polyethylene glycol ester monomer is 200-1000. The invention also discloses a preparation method of the surfactant, which comprises the following steps: performing D-A addition on rosin and acrylic acid to prepare acrylic rosin, performing esterification reaction on the acrylic rosin and glycidyl methacrylate to generate oleophylic monomer acrylic rosin glycidyl methacrylate, and performing free radical copolymerization reaction on the oleophylic monomer acrylic rosin glycidyl methacrylate and hydrophilic monomer polyethylene glycol methacrylate (200-1000) according to the weight ratio of different substances to obtain a high molecular surfactant, wherein the number average molecular weight range of the obtained high molecular surfactant is 2282-6598; the critical micelle concentration range of the prepared surfactant is 0.008-0.01 g/L, and the surface tension range is 54.8-55.5 mN/m; the invention also discloses the application of the surfactant as a dispersing agent, the carbon nano tube is dispersed by strong hydrophobic effect and van der Waals force, and a transmission electron microscope shows that the surfactant has good dispersing performance on the carbon nano tube. |
