The invention discloses an efficient plastic
toughening agent, and belongs to the field of
high polymer materials. According to the efficient plastic
toughening agent,
acrylic acid,
maleic anhydride and the like are taken as monomers, different degrees of graft modification are conducted in a reaction kettle to form a
monomer mixture with good compatibility, so that good
toughness is achieved after application to plastic, and cracks are not prone to being generated; an added
dopamine solution can undergo oxidative auto-
polymerization reaction under alkalescence conditions, through the effectsof covalent bonds, non-covalent bonds, and
hydrogen bonds, a role of adhesion between components is firmly played, internal stability is improved, the component of
graphene oxide added in the subsequent process has a large specific surface area, the surface contains functional groups such as carboxyl groups, absorption on the surface of positively charged
polyelectrolyte can be realized through electrostatic action, reinforcing action on a multilayer
network structure is realized, the
toughness can be improved to a large extent, so that the cracks are not prone to being generated. According tothe efficient plastic
toughening agent, the problems that in the prior art the commonly used plastic toughening agent is great in
brittleness after being used and prone to generating cracks when subjected to external forces are solved.
