PM2.5 mask filter paper and preparation method thereof

Abstract

The invention discloses PM2.5 mask filter paper which is prepared from the following components in parts by weight: 20 to 30 parts of modified hemp pulp, 5 to 8 parts of a diatomite / ferroferric oxidecomposite material and 6 to 8 parts of a hot melt adhesive. A preparation method of the PM2.5 mask filter paper is characterized by comprising the following steps of: A1, preparing hemp pulp; A2, modifying the hemp pulp; A3, preparing a diatomite / ferroferric oxide composite material; A4, flaking and molding. The diatomite is applied in the invention; the diatomite has the effects of absorbing formaldehyde, absorbing peculiar smell, deodorizing, sterilizing, disinfecting, purifying air, releasing negative oxygen ions and the like, are uniformly distributed after being loaded by a ferroferric oxide nano material, and are not easy to agglomerate.

Description

technical field [0001] The invention mainly relates to the technical field of environmental protection, in particular to a PM2.5 mask filter paper and a preparation method thereof. Background technique [0002] With the gradual enhancement of people's awareness of environmental protection, the consumption of protective masks is also increasing, but the quality of protective masks in the domestic market varies widely. On November 1, 2016, my country's first national standard for protective masks for civilian use - GB / T32610--2016 "Technical Specifications for Daily Protective Masks"... was officially implemented, which marks that protective masks have been included in standardized management. At present, the protection of domestic protective masks is far from that of imported protective masks, which makes people prefer to buy imported protective masks at high prices rather than low-priced domestic protective masks. But in fact, regardless of whether it is an imported or a do...

Problems solved by technology

At present, the protection of domestic protective masks is far from that of imported protective masks, which makes people prefer to buy imported protective masks at high prices rather than low-priced domestic protective masks.

But in fact, no matter whether it is an imported or a domestic protective mask, because each person's face shape is different, it is impossible to fit the face very tightly when wearing it, and there will be more or less a gas short circuit phenomenon (that is, the peripheral air Enter from the gap between the mask and the face and be inhaled by the human body)
