摘要
Abstract
Rigid polyurethane foam(RPUF),as a type of high-performance thermal insulation material,is widely used in construction,refrigeration,pipeline transportation,and other fields.However,its flammability presents a significant safety hazard.Although conventional halogenated flame retardants can effectively enhance its flame retardancy,they also pose serious environmental risks.Therefore,the development of halogen-free flame retardant systems has become partic-ularly crucial.This article reviews recent research progress in halogen-free flame retardant systems for the flame retar-dant modification of rigid polyurethane foam.These systems include inorganic flame retardants,organic phosphorus-based flame retardants,and other halogen-free alternatives,with a focus on the effects of these three types of flame retar-dants on the flame retardancy of RPUF.Finally,the article discusses the application of novel materials in RPUF flame retardant modification in recent years and outlines potential future research directions.关键词
