The research status of flame-retardant straw composite materials were reviewed.The flame-retardant methods of straw materials and the research progress on flame retardant of straw composite board,straw foam materials and wood plastic materials were mainly introduced,and analyzed the shortcomings of straw composites.A large number of straw burning has caused the air pollution in rural areas and surrounding cities to intensify.Therefore,it is imperative to improve the utilization rate of crop straw resources.With the continuous innovation in straw material research technology,flame-retardant straw composite materials have become a research hotspot in the field of straw building materials.
