Epoxidized soybean oil modified phenolic resin as well as preparation method and application thereof

Abstract

The invention provides epoxidized soybean oil modified phenolic resin as well as a preparation method and application thereof. The epoxidized soybean oil modified phenolic resin provided by the invention is prepared from the following raw materials in parts by weight: 1200-1600 parts of epoxidized soybean oil, 500-700 parts of phenol, 1000-1300 parts of bisphenol A, 5-10 parts of 2-methylimidazole, 800-1200 parts of formaldehyde, 60-150 parts of basic catalysts, 2500-3000 parts of solvents, 5-60 parts of graphene and 5-40 parts of graphene oxide. The epoxidized soybean oil modified phenolic resin provided by the invention has the beneficial effects that the epoxidized soybean oil modified phenolic resin utilizes the epoxidized soybean oil, graphene and graphene oxide to simultaneously achieve the effects of toughening modification and heat resistance modification and meets the performance requirements of the industry for phenolic resin; the epoxidized soybean oil modified phenolic resin provided by the invention is simple in preparation method and low in raw material prices, meets the increasing production requirements of a copper-clad plate and has high economic benefits; besides, the quality of the copper-clad plate prepared from the epoxidized soybean oil modified phenolic resin is improved while reduction of the production cost is ensured; the copper-clad plate has high use value.
