영문 초록

Although the basalt fiber has superior fire-resistance and chemical resistance, it has many disadvantages in its applications. Generally, the tensile and loop strengths of basalt fiber were decreased with generated frictional heat during industial appplications. To solve this problem, polytetrafluoroethylene (PTFE) coating system was introduced and a sutable coating condition was evaluated. The basalt fiber was pre-treated with triethoxytrifluoropropylsilane (TMTFPS) at various pHs and then coated with PTFE dispersions with penetrating agent sodium bis(2-ethylhexyl)sulfo succinate (DOS-Na) to increase the tensile and loop strengths as well as to reduce the fibril during working. A universial testing machine (Instron Model 3366) was used to measure tensile and loop strengths. When the PTFE dispersion with 0.25 wt% of DOS-Na was coated on the surface of basalt fiber after pre-treating with 5 wt% of PTFE, the highest tensile and loop strengths were reached to 3.5 gf/D and 2.4 gf/D, respectively
