Study on Fire-Retardant Mechanism and Fire-Retardant Recipe of Self-Lock FRP Bolt

摘要

The important significance of the fire-retardant property of fibre reinforced plastics bolt for production safety of coal mine is illustrated. The fire-retardant mechanism of general composite is analyzed. Especially, bromine-antimony compounding fire-retardant characteristics is studied. According to the properties of the raw material of fibre reinforced plastics bolt, appropriate fire retardant agents are choose and tested. The results show the fire-retardant agents have fine performance when ratio of Sb2O3 to C_(12)Br_(10)O is 1:4. So the rational experimental recipe of fibre reinforced plastics bolt with fire-retardant characteristics is found.
