Automobile formaldehyde eliminating cushion

Abstract

The invention relates to an automobile formaldehyde elimination back cushion. The technical solution adopted is that there are adsorption particles built into the core of the cushion, and the adsorption particles include fruit shell activated carbon, wood activated carbon, and coconut shell activated carbon. The adsorption particles are wrapped in a graphene film, and the surface of the graphene film is loaded with nanometer particle. The specific measures are: the adsorption particles are packed in a non-woven bag, the non-woven bag is packed in a graphene film bag, the graphene film bag has holes on both sides to facilitate air circulation from here, and the outer layer of the graphene film bag is provided with a flexible material , the outermost layer is the cushion cover. In this way, the minimum graphene is used to achieve the maximum extended specific surface area on the surface of the activated carbon, and more nanoparticles can be loaded to achieve high adsorption while reducing costs. And when the nanoparticles are photocatalytic nanoparticles, the purifier can absorb the polluted gas under the light and catalyze it to decompose, so that the graphene film bag can be reused. In the absence of light, the activated carbon particles and the graphene film can also be opened. Adsorption function. The beneficial effect is that one thing can be used for two purposes, and the effect of eliminating formaldehyde is good.

Description

technical field [0001] The invention relates to the technical field of purification and sterilization, in particular to an automobile formaldehyde elimination cushion. Background technique [0002] Formaldehyde in newly purchased cars is quite serious. Consumers often solve it through natural elimination. This is undoubtedly a negative attitude. Although there are also methods such as putting citrus shells and onions in the car, the effect is not certain. In the prior art, activated carbon such as bamboo charcoal is also used to purify the air by adsorbing polluted gases. However, during the use of activated carbon, a large amount of pollutant gases are adsorbed and covered on the surface of activated carbon, which makes activated carbon invalid. Graphene is a single-atom-thick two-dimensional carbon atom crystal with unique electrons, and its unique two-dimensional structure makes graphene a very ideal carrier for nanoparticles to prepare graphene-based composite materials...

However, during the use of activated carbon, a large amount of pollutant gas is adsorbed and covered on the surface of activated carbon, which makes activated carbon invalid.

Graphene is a single-atom-thick two-dimensional carbon atom crystal with unique electrons, and its unique two-dimensional structure makes graphene a very ideal carrier for nanoparticles to prepare graphene-based composite materials. In the prior art, CN201210237714 .5 discloses a preparation method of nano-magnetic cyclodextrin / graphene bio-adsorption material. Nano-magnetic cyclodextrin is modified on the surface of graphene, which greatly increases the specific surface area of ​​the adsorption material and expands the range of adsorption objects. However, the production cost of the above materials is too high
