The Japan Science and Technology Agency recently issued a press release saying that a chemical company in Osaka Prefecture has been commissioned by the agency to develop a new technology that will help mass-produce environmentally friendly phosphorus-based flame retardants in the future.
According to the communique, plastic is an indispensable material for daily life and industrial production, but most types of plastic are flammable. In order to make plastics difficult to burn, the flame retardants currently used are mostly halogen flame retardants. The agent contains harmful halogen elements, which tend to pollute the environment after the product is discarded.
Environmental friendly phosphorous flame retardants have attracted attention as substitutes for halogenated flame retardants for many years. However, these flame retardants are mostly liquid, and the added durability and water resistance of plastics are reduced.
In this study, the researchers at Kitayama Chemical Industrial Co., Ltd. abandoned the previous method of physical mixing and instead introduced phosphorus directly into the backbone of the polymer resin to achieve a stable flame retardant performance. The mechanical properties and water resistance of the plastic added with this flame retardant have not decreased, and the flame resistance has been greatly improved.
The communique said that in this study, the researchers used cationic nickel metal hydride catalysts that were developed using cheap nickel chloride as a raw material to efficiently catalyze the synthesis of flame retardants, which will help future mass production Environmentally friendly phosphorus flame retardant.
