Embodiment 1

[0027] Such as figure 1 As shown, the traditional Chinese medicine protective mask filter element for purifying PM2.5 includes a three-layer structure. From the outside to the inside, there are spunbond non-woven fabric layer, activated carbon fiber non-woven fabric layer and inner cotton spinning layer. It is made of melt glue, and the outer periphery of the inner cotton spinning layer is provided with self-adhesive.

[0028] The preparation method of the activated carbon fiber type non-woven fabric layer is to make the activated carbon fiber type non-woven fabric by spraying the mixed extract of traditional Chinese medicine.

[0029] The preparation method of the mixed Chinese medicine extract is to weigh 20g magnolia magnolia, 10g peppermint, 10g licorice, 40g isatidis, and 20g Baibu five kinds of traditional Chinese medicines, and mix the extracts obtained by extracting each Chinese medicine separately, and the mixed extracts are mixed according to the volume of 1:5 More ...

Embodiment 2

[0031] The structure of the traditional Chinese medicine protective mask filter element for purifying PM2.5 is the same as that in Example 1.

[0032] The preparation method of the activated carbon fiber type non-woven fabric layer is to make the activated carbon fiber type non-woven fabric by spraying the mixed extract of traditional Chinese medicine.

[0033] The preparation method of the mixed Chinese medicine extract is to weigh 30g magnolia magnolia, 5g peppermint, 20g licorice, 35g isatidis, and 10g Baibu five kinds of traditional Chinese medicines. Soluble in 65% ethanol solution, that is.

Embodiment 3

[0035] The structure of the traditional Chinese medicine protective mask filter element for purifying PM2.5 is the same as that in Example 1.

[0036] The preparation method of the activated carbon fiber type non-woven fabric layer is to make the activated carbon fiber type non-woven fabric by spraying the mixed extract of traditional Chinese medicine.

[0037] The preparation method of the mixed Chinese medicine extract is to weigh 26g magnolia magnolia, 8g peppermint, 18g licorice, 30g isatidis, and 18g Baibu five kinds of traditional Chinese medicines, and mix the extracts obtained by extracting each traditional Chinese medicine separately. It is more soluble in 90% ethanol solution, that is, too.

Abstract

The invention belongs to the technical field of mask filter elements and particularly relates to a traditional Chinese medicine protective mask filter element capable of filtering PM2.5, which comprises three layers of structures, including a spunbond non-woven fabric layer, an activated carbon fiber non-woven fabric layer and a lining cotton textile layer from outside to inside in sequence, wherein all the layers are adhered to one another through hot melt adhesive; non-setting adhesive is arranged at the periphery of the outer side of the lining cotton textile layer; the activated carbon fiber non-woven fabric layer is prepared through the method that a traditional Chinese medicine mixed extracting solution is sprayed onto an activated carbon fiber non-woven fabric. The traditional Chinese medicine protective mask filter element capable of filtering PM2.5 is simple in structure, low in cost and simple to manufacture, has high filtration and absorption effects, adopts a traditional Chinese medicine nursing leaching solution, and can moisten and protect lung and treat respiratory diseases; besides, the hot melt adhesive is applied to connecting of the mask filter element and a mask main body for the first time, the operation is simple and convenient, the efficiency is improved and resources are saved.

Description

technical field [0001] The invention belongs to the technical field of mask filter elements, in particular to a traditional Chinese medicine protective mask filter element for purifying PM2.5. Background technique [0002] Current status of PM2.5 pollution: my country's urban ambient air particulate pollution presents a multi-type pollution situation, which can be divided into: traditional soot type, such as Urumqi, Lanzhou, Taiyuan, etc. (especially in winter); soot, dust and motor vehicle mixed type, such as Zhengzhou, Shijiazhuang, etc.; compound type, such as Beijing, Tianjin, Guangzhou, etc. With the rapid development of the economy, the air pollution problems that have occurred in foreign countries for decades have concentrated in many cities in my country, presenting a complex and compressed form. At present, more than two-thirds of the cities in my country have substandard air quality and have entered the stage of large-scale ecological degradation and complex enviro...
