Abstract

The invention relates to an energy increasing additive added multi-layer melt-blown composite filter material and a preparation method thereof. The multi-layer melt-blown composite filter material comprises a dust surface layer melt-blown material, a middle layer melt-blown material and a fine filtration layer melt-blown material and is prepared by steps: subjecting raw materials to melt blowing in a melt blowing device to form the dust surface layer melt-blown material, the middle layer melt-blown material and the fine filtration layer melt-blown material sequentially, compounding, and performing corona electret treatment to obtain the energy increasing additive added multi-layer melt-blown composite filter material. The energy increasing additive added multi-layer melt-blown composite filter material is simple in process route, low in implementation cost and easy in industrial popularization; on the one hand, due to a gradient structure, material bulkiness can be improved, and filtration efficiency attenuation can be decelerated while filtration efficiency is improved.

Description

technical field [0001] The invention belongs to the field of composite filter material and its preparation, in particular to a multi-layer melt-blown composite filter material added with energy-enhancing additives and a preparation method thereof. Background technique [0002] In recent years, with the development of the economy and the improvement of people's living standards, people's requirements for the quality of the environment are also getting higher and higher. But at the same time of economic development, it also brought a series of environmental problems. Since 2012, the smog weather in Beijing and other places has intensified. The smog is mainly composed of sulfur dioxide, nitrogen oxides and inhalable particulate matter. These fine particulate matter inhaled into the human body may cause great damage to the respiratory tract and lungs. Therefore, effective control of harmful substances in the air is a major problem to be solved, and the application of air filter...
