Abstract: Reviews were made on researches on wood fire-retardanting in China, including halogen fire-retardant, metal fire-retardant,nitrogen-phosphorus-boron compounded fire-retardant. Relative standards of the EU, USA, Japan, China were presented as well as drug loadingcapacity, smokiness, hygroscopicity, environmental protection of fire-retarding wood. Suggestions were put forwarded on the further researchdirection of wood fire-retarding, such as high fire-retarding wood with low hygroscopicity-smokiness and new treatments of fire-retardants.
