Problems solved by technology

Traditional anti-smog masks and filter-type anti-particulate respirators can only intercept larger particles in the air, which is difficult to play a protective role. The existing N95 masks have poor ventilation and large gas resistance while ensuring filtration efficiency. It cannot be worn for a long time, and it cannot play an antibacterial role

Embodiment Construction

[0018] A method for preparing a graphene filter particle respirator antibacterial filter element, comprising the steps of:

[0019] Step 1. Prepare graphite oxide, mix nitric acid and sulfuric acid and lower the temperature to 5ºC and maintain this temperature, add graphite and then add NaClO 3 solution, continue to stir and react, then filter and wash to obtain graphite oxide.

[0020] The mixed acid of nitric acid and sulfuric acid has strong oxidizing properties, which is beneficial to the oxidation of graphite and the intercalation reaction. During the process of mixing sulfuric acid and nitric acid solutions, a lot of heat will be released, and the reaction speed with graphite is too fast to be controlled. It is necessary to lower the temperature of the solution to 5ºC before adding graphite to ensure the safety of subsequent reactions. NaClO 3 HClO will be generated in the mixed acid system 3 , has strong oxidizing properties, and achieves the purpose of re-oxidizing ...

Abstract

The invention relates to the technical field of mask filter elements, in particular to a graphene filter particle respirator anti-microbial filter element preparing method and a prepared filter element. The graphene filter particle respirator anti-microbial filter element preparing method comprises the following steps that firstly, graphite oxide is prepared; secondly, a graphene oxide viscous solution is prepared; and thirdly, melt-blown non-woven fabrics continuously pass through the obtained viscous solution and then are dried through rolling liquid and a roller, and a graphene oxide melt-blown non-woven fabric composite film is prepared to serve as the mask anti-microbial filter element. According to the graphene filter particle respirator anti-microbial filter element preparing methodand the prepared filter element, the excellent adsorption performance, obstruction performance and anti-microbial performance of graphene are utilized, the graphene material is used for the mask filter element so that the filter performance of a mask for solid particles in air can be effectively improved, meanwhile, the function of peculiar smell removal is achieved, and good anti-microbial performance is achieved.

Description

technical field [0001] The invention relates to the technical field of mask filter elements, in particular to a method for preparing an antibacterial filter element for a graphene-filtered particle respirator and the prepared filter element. Background technique [0002] The domestic economy is in a period of rapid development, people's living standards continue to improve, car ownership continues to increase, and industrial activities are more active. As a result, the environment on which human beings depend has been seriously polluted, especially the smog and sudden outbreaks in recent years. Infectious diseases have seriously affected human health. At the same time, fine particles in smoggy weather can carry a large amount of bacteria, viruses, toxic and harmful organic substances and heavy metals. Such particles stay in the air for a long time and travel long distances, which are extremely harmful to human health. The most effective personal protective measure in haze w...
