ECTFE melt-blown filter material and preparation method thereof

The invention discloses an ECTFE melt-blown filter material and a preparation method thereof. The ECTFE melt-blown filter material has an average pore size of 0.1 [mu] m-100 [mu] m, a fiber diameter of 0.05 [mu] m-50 [mu] m, a longitudinal tensile breaking strength of 15-100 N and a transverse tensile breaking strength of 10-50 N. The invention also discloses a preparation method of the ECTFE melt-blown filter material. The ECTFE melt-blown filtering material has the advantages of high tensile strength, high elongation at break and high filtering precision, and is suitable for severe environments with high temperature resistance, acid and alkali resistance, corrosion resistance and the like. 本发明公开了一种ECTFE熔喷过滤材料及其制备方法，所述ECTFE熔喷过滤材料平均孔径为0.1μm～100μm，纤维直径为0.05μm～50μm，纵向拉伸断裂强力为15N～100N，横向拉伸断裂强力为10N～50N。本发明的ECTFE熔喷过滤材料拉伸强度大，断裂伸长率高，过滤精度高，适用于耐高温、耐酸碱及耐腐蚀等苛刻环境。
