Cerium ion coordinated terpyridyl anticorrosive flame-retardant difunctional filler as well as preparation method and application thereof

Abstract

The invention discloses a cerium ion coordinated terpyridyl anticorrosive flame-retardant difunctional filler as well as a preparation method and application thereof. The structural formula of the cerium ion coordinated terpyridyl anticorrosive flame-retardant difunctional filler is # imgabs0. The corrosion-resistant flame-retardant EP material has corrosion-resistant and flame-retardant dual-functional characteristics, and the toughness of EP is improved by using a siloxane skeleton structure as a connecting agent; dOPO contains phosphorus, a phosphorus compound can be decomposed at high temperature to generate phosphorus oxides, the oxides can form a protective layer in flame, interaction between oxygen and combustible materials is reduced, and combustion reaction is slowed down or inhibited; pyridine can adsorb metal ions in a corrosive environment, so that an anti-corrosion effect is achieved; meanwhile, N atoms on a pyridine ring can generate N2 in the combustion process, so that the concentration of oxygen in the gas can be reduced, and an important role is played in the intumescent flame retardant process; ce < 3 + > and pyridine are coordinated to form a coordination compound, a compact adsorption film is formed on the surface of a matrix, and corrosion protection is provided; meanwhile, various micromolecular monomers can be combined to form a long-chain chelate, so that the performance of the filler is further improved.
