Application of phenylphosphine ferrocene as smoke suppressant in epoxy resin

Abstract

The invention discloses the application of phenylphosphine ferrocene as a smoke suppressant in epoxy resin. On the premise of ensuring the smoke suppressant, the invention does not reduce the flame retardant efficiency of phosphorus flame retardant, which is very important. application value.

Description

Application of phenylphosphine ferrocene as smoke suppressant in epoxy resin technical field The present invention relates to flame retardant field, be specifically related to a kind of phenylphosphine ferrocene in epoxy resin as smoke suppressant application. Background technique Epoxy resin, as one of the three major thermosetting resins, has been widely used in fields such as adhesives, coatings, and electrical appliances. use. Due to its flammability, the limiting oxygen index (LOI) is only 19.0%, which can easily lead to fire. Therefore, phosphorus-based systems are commonly used. The flame retardant DOPO is used for flame retardant treatment. However, in recent years, people have found that burning in fire through research on fire. The large amount of smoke generated during the combustion process can easily lead to casualties. Therefore, it is of great significance to reduce the generation of smoke during the combustion process. righteous. As a kind of tra...
