More Information
Summary:The invention provides a support layer material used for a filter membrane, and a preparation method of the support layer material. The support layer material is quantified to be 40-80g/m , the thickness is 50-130mum, the average pore size is 9-35mum, the quantitative uneven rate is smaller than or equal to 3%, and the porosity is larger than or equal to 80%. The invention further provides a filter membrane prepared by adopting the support layer material. The support layer material provided by the invention has better surface smoothness, compactness and overall evenness, and is strong in tension stress.
