Abstract

The invention belongs to the technical field of high polymer materials, and particularly relates to modified graphene oxide / eleostearic acid maleic anhydride vinyl ester anticorrosive resin as well as a preparation method and application thereof. Modified graphene oxide covered with silicon dioxide and containing terminal epoxy groups is synthesized, the modified graphene oxide is ultrasonically dispersed in epoxy resin, unsaturated monobasic acid is used for semi-blocking, eleostearic acid maleic anhydride is used for chain extension, finally, an active diluent is added for adjusting viscosity, and the finished resin is obtained. The modified graphene oxide is introduced into the eleostearic acid maleic anhydride vinyl ester anticorrosive resin and is uniformly dispersed in the resin, so that the anticorrosive property of the resin is greatly improved.

Description

Technical field [0001] The present invention belongs to the field of polymer material technology, specifically relates to a modified graphene oxide / tung oleic acid maleic acid vinyl ester antiseptic resin preparation method and the use of the preparation method prepared of modified graphene oxide / tung oleic acid maleic anhydride vinyl ester antiseptic resin and its application. Background [0002] Surface coating technology plays an important role in daily life, by coating the substrate surface of metal, textiles, plastics, can play a role in protection, decoration, protection and so on. The marine area accounts for 71% of the earth's area, and the marine environment is a highly corrosive environment due to the large number of metal ions, so the research of marine anti-corrosion coatings is crucial. [0003] Vinyl ester coating is a metal anti-corrosion coating that has emerged in recent years, because its structure contains more benzene ring rigid structure, so it has certai...
