Abstract

Flame retardants are key ingredients for gas sealing materials used in the coal mine wall. In this paper, the types and doses of flame retardants are investigated. The results showed that a gas sealing material with 11 wt % complex flame retardants had a good performance when the complex flame retardants were composed of aluminum hydroxide and chlorinated paraffin at a ratio of 3:8. The flame resistant property of this gas sealing material conforms to the safety standards of coal mines (MT113-1995). Furthermore, their mechanical properties met the standard requirements of the polymer cement waterproof coatings (GB/T23445-2009). The costs are very low compared with similar products in current practical use.
