Polypropylene electret filter material with efficient filtering and sterilizing performance and preparing method thereof

Abstract

The invention discloses a polypropylene electret filter material with efficient filtering and sterilizing performance. The polypropylene electret filter material is prepared from, by weight, 55-65 parts of polypropylene, 9-14 parts of silicon monoxide, 11-17 parts of powdered activated carbon, 2-5 parts of a 3-aminopropyl triethoxysilane coupling agent, 0.5-1.5 parts of glacial acetic acid, a proper amount of deionized water, 1-3 parts of low-density polyethylene wax, 0.5-2 parts of an antioxidant 1010, 0.6-1.4 parts of a titanate coupling agent, 7-10 parts of silicon dioxide and 5-8 parts of far-infrared ceramic powder. According to the polypropylene electret filter material with efficient filtering and sterilizing performance, silicon nanowires containing alpha-quartz are prepared and added into a melt-blow polypropylene electret material, and the melt-blow polypropylene electret material has excellent filtering efficiency and a remarkable bacterium propagation suppressing function; active carbon is used for carrying the silicon nanowires treated with the silane coupling agent, so that the carrying amount of active carbon on the silicon nanowires is increased, and more harmful substances in air can be effectively adsorbed by the filter material.

Description

technical field [0001] The invention belongs to the field of air filtration, and in particular relates to a polypropylene electret filter material with high-efficiency filtration and bactericidal performance and a preparation method thereof. [0002] technical background [0003] With the progress of the times, people's requirements for environmental quality are getting higher and higher. However, the rapid economic development has aggravated the pollution of the environment, and the dust, chemicals, and harmful microorganisms in the air have had adverse effects on people's health. Therefore, effective control of harmful substances in the air is a major problem to be solved. The application of air filters and filter materials is an important means of purifying the air. Ordinary air filter materials are not thorough enough to remove fine particles, and harmful microorganisms are easy to breed on the filter materials, and there is a possibility of secondary pollution.
