Abstract

The invention relates to a polypropylene melt-blow non-woven filter material, in particular to an antibacterial polypropylene melt-blow non-woven filter material and a preparation method thereof. The polypropylene melt-blow non-woven filter material is prepared from the following raw materials in parts by weight: 85-95 parts of melt-blow polypropylene slices, 1-5 parts of nanometer tourmaline, 1-3 parts of nanometer titanium oxide, 1-3 parts of nanometer zinc oxide, 0.1-3 parts of a coupling agent, 0.1-2 parts of a dispersing agent and 0-0.5 part of an antioxidant. According to the antibacterial polypropylene melt-blow non-woven filter material prepared with the method, a formula and a preparation process are improved, so that the electret polarity time of the prepared filter material can be up to 5-6 years, and the antibacterial performance is superior to the prior art.

Description

technical field [0001] The invention relates to a polypropylene melt-blown non-woven filter material, in particular to an antibacterial polypropylene melt-blown non-woven filter material and a preparation method. Background technique [0002] At present, electrets have been widely used in air filter materials. Electret refers to a functional dielectric material with the ability to store charges for a long time, and electrostatic, piezoelectric and pyroelectric effects are its basic physical effects. By applying a strong electric field to certain dielectric materials (such as polymers, etc.), and using certain physical and chemical methods to make the charge or electric polarization state stay on the dielectric for a long time, long-life electrets can be made. [0003] At present, electret has been widely used in engineering technology, medicine, biology and so on. In the electret air filter material, the electrostatic effect is used. Ordinary air filter materials generall...
